  • Cannot return view model after POST

    - by Interfector
    HI, I am trying to return a model after a POST but I receive the following error: Exception Details: System.InvalidOperationException: Operation is not valid due to the current state of the object. Line 29: public UsersModel getUser(Int32 id) { Line 30: return ( Line 31: from users in db.NUsers Line 32: join userSettings in db.NUsersSettings The code in the controller looks like this: [AcceptVerbs( HttpVerbs.Post )] public ActionResult Edit( NUsers user ) { //Other code that doesn't affect the error :) UsersModel userDetails = this.usersObj.getUser( user.UserID ); return View( userDetails ); } The getUser method looks like this: public UsersModel getUser(Int32 id) { return ( from users in db.NUsers join userSettings in db.NUsersSettings on users.UserID equals userSettings.UserID where users.UserID == id select new UsersModel { UserId = Convert.ToInt32( users.UserID ), Email = Convert.ToString( users.Email ), FirstName = Convert.ToString( users.FirstName ), LastName = Convert.ToString( users.LastName ), Language = Convert.ToString( userSettings.Language ), Phone = Convert.ToString( users.Phone ) } ).First(); } and finally the UsersModel if you think it is relevant: public class UsersModel { public int UserId; public string Email; public string FirstName; public string LastName; public string Language; public string Phone; public List<NLanguages> Languages; public UsersModel() { Models.Languages languagesObj = new Models.Languages(); Languages = languagesObj.getLanguages(); } } Any thoughts on what might be causing the error and what can I do to fix it? Thx

    Hi all I read http://forum.kohanaframework.org/comments.php?DiscussionID=5744&page=1#Item_0 and I want to use similar solution, but with db. In my site controller after(): $theme = $page->get_theme_name(); //Orange Kohana::set_module_path('themes', Kohana::get_module_path('themes').'/'.$theme); $this->template = View::factory('layout') I checked with firebug: fire::log(Kohana::get_module_path('themes')); // D:\tools\xampp\htdocs\kohana\themes/Orange I am sure that path exists. I have directly in 'Orange' folder 'views' folder with layout.php file.

  • Cache of Objects or OutPut in View ? Wich is better ?

    - by Felipe
    Hi everybody, I have an ecommerce working in ASP.Net MVC. i'm using Caching to improve more performace in my pages and it's working fine. I'd link to know what is more performative, for example, I can set OutPutCache in my views and and use this cache for all page OR I could get my List of Products in controller, put it on cache (like the code below) and send it to View to render for the user??? private IEnumerable<Products> GetProductsCache(string key, ProductType type) { if (HttpContext.Cache[key] == null) HttpContext.Cache.Insert(key, ProductRepository.GetProducts(type), null, DateTime.Now.AddMinutes(10), Cache.NoSlidingExpiration); return (IEnumerable<Products>)HttpContext.Cache[key]; } public ActionResult Index() { var home = new HomeViewModel() { Products = GetProductsCache("ProductHomeCache", ProductType.Product) Services = GetProductsCache("ServiceHomeCache", ProductType.Service) }; return View(home); } Both works fine, but I'd like to know what is suggested to improve more performace ? Or is there others way to do it better ? PS: sorry for my english! thanks all... Cheers

  • Sorting by dates (including nil) with NSFetchedResultsController

    - by glorifiedHacker
    In my NSFetchedResultsController, I set a sortDescriptor that sorts based on the date property of my managed objects. The problem that I have encountered (along with several others according to Google) is that nil values are sorted at the earliest end rather than the latest end of the date spectrum. I want my list to be sorted earliest, earlier, now, later, latest, nil. As I understand it, this sorting is done at the database level in SQLite and so I cannot construct my own compare: method to provide the sorting I want. I don't want to manually sort in memory, because I would have to give up all of the benefits of NSFetchedResultsController. I can't do compound sorting because the sectionNameKeyPaths are tightly coupled to the date ranges. I could write a routine that redirects indexPath requests so that section 0 in the results controller gets mapped to the last section of the tableView, but I fear that would add a lot of overhead, severely increase the complexity of my code, and be very, very error-prone. The latest idea that I am considering is to map all nil dates to the furthest future date that NSDate supports. My left brain hates this idea, as it feels more like a hack. It will also take a bit of work to implement, since checking for nil factors heavily into how I process dates in my app. I don't want to go this route without first checking for better options. Can anyone think of a better way to get around this problem?

  • How to create an Universal Binary for iTunes Connect Distribution?

    - by balexandre
    I created an app that was rejected because Apple say that my App was not showing the correct iPad window and it was showing the same iPhone screen but top left aligned. Running on simulator, I get my App to show exactly what it should, a big iPad View. my app as Apple referees that is showing on device: my app running the simulator (50% zoom only): my code in the Application Delegate is the one I published before - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // The default have the line below, let us comment it //MainViewController *aController = [[MainViewController alloc] initWithNibName:@"MainView" bundle:nil]; // Our main controller MainViewController *aController = nil; // Is this OS 3.2.0+ ? #if __IPHONE_OS_VERSION_MAX_ALLOWED >= 30200 if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) // It's an iPad, let's set the MainView to our MainView-iPad aController = [[MainViewController alloc] initWithNibName:@"MainView-iPad" bundle:nil]; else // This is a 3.2.0+ but not an iPad (for future, when iPhone/iPod Touch runs with same OS than iPad) aController = [[MainViewController alloc] initWithNibName:@"MainView" bundle:nil]; #else // It's an iPhone/iPod Touch (OS < 3.2.0) aController = [[MainViewController alloc] initWithNibName:@"MainView" bundle:nil]; #endif // Let's continue our default code self.mainViewController = aController; [aController release]; mainViewController.view.frame = [UIScreen mainScreen].applicationFrame; [window addSubview:[mainViewController view]]; [window makeKeyAndVisible]; return YES; } on my target info I have iPhone/iPad My question is, how should I build the app? Use Base SDK iPhone Simulator 3.1.3 iPhone Simulator 3.2 my Active Configuration is Distribution and Active Architecture is arm6 Can anyone that already published app into iTunes Connect explain me the settings? P.S. I followed the Developer Guideline on Building and Installing your Development Application that is found on Creating and Downloading Development Provisioning Profiles but does not say anything regarding this, as I did exactly and the app was rejected.

  • Passing an NSDate

    - by Garry
    I'm new to the iPhone and objective-c and I am still trying to get my head around ownership of objects so bear with me. I have a DOBViewController that has a datepicker on it. I have created a custom init method: -(id)initWithInitialDate(NSDate *)initialDate; Another view controller has a date instance declared (NSDate *dob) that holds a value. I would like to pass this to the DOBViewController so that it can scroll the datepicker to the passed value. Here is the custom init method: - (id)initWithInitialDate:(NSDate *)initialDate { // Initialise ourselves self = [super init]; // Set the date of the date picker if (initialDate != nil) { datePicker.date = initialDate; } else { // Set it to today datePicker.date = [NSDate date]; } return self; } This is how I am sending the dob NSDate object: DOBViewController *dobViewController = [[DOBViewController alloc] initWithInitialDate:dob]; Where dob is a variable of type NSDate that is declared in the header file. This doesn't seem to work as initialDate is always NULL. What am I doing wrong?

  • jEditable - how do I get the edited textfield variable?

    - by Forkrul Assail
    I have a table that I use jEditable with. Saving to the server works, but the callback for refreshing my table element (that I just edited and saved to the server) does not work. /* Apply the jEditable handlers to the table */ $('#example tbody td').editable( '<%= url_for :controller => 'impact_matrix', :action => 'post', :scenario => params[:id] %>', { "callback": function( sValue, y ) { ^ goes missing var aPos = oTable.fnGetPosition( this ); oTable.fnUpdate( sValue, aPos[0], aPos[1] ); }, "submitdata": function ( value, settings ) { temp = value return { "row_id": this.parentNode.getAttribute('id') }; }, sValue (that I point to in the code) - seems to be blank. I do get values for aPos[0] and aPos[1], but not sValue. Could someone please explain to me 'what triggers the callback function?' Or, if I could just see where to get the 'newly edited text' and then just run fnUpdate() on that, I'd be fine. Thanks in advance for your help.

  • Why do i get exc bad access in cases when object is not nil?

    - by DixieFlatline
    I have an app that receives remote notifications. My view controller that is shown after push has a tableview. App crashes very randomly (1 in 20 tries) at line setting frame: if (!myTableView) { NSLog(@"self.myTableView is nil"); } myTableView.frame=CGRectMake(0, 70, 320, 376); This only happens when i open the app, then open some other apps and then receive the push notification. I guess it has something to do with memory. I use ARC (ios 5). The strange thing is that nslog is not displayed, so tableview is not nil. Crash log: Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Codes: KERN_INVALID_ADDRESS at 0x522d580c Crashed Thread: 0 Thread 0 name: Dispatch queue: com.apple.main-thread Thread 0 Crashed: 0 libobjc.A.dylib 0x352b1f7e objc_msgSend + 22 1 Foundation 0x37dc174c NSKVOPendingNotificationCreate + 216 2 Foundation 0x37dc1652 NSKeyValuePushPendingNotificationPerThread + 62 3 Foundation 0x37db3744 NSKeyValueWillChange + 408 4 Foundation 0x37d8a848 -[NSObject(NSKeyValueObserverNotification) willChangeValueForKey:] + 176 5 Foundation 0x37e0ca14 _NSSetPointValueAndNotify + 76 6 UIKit 0x312af25a -[UIScrollView(Static) _adjustContentOffsetIfNecessary] + 1890 7 UIKit 0x312cca54 -[UIScrollView setFrame:] + 548 8 UIKit 0x312cc802 -[UITableView setFrame:] + 182 9 POViO 0x000913cc -[FeedVC viewWillAppear:] (FeedVC.m:303) Dealloc is not called because it is not logged: - (void)dealloc { NSLog(@"dealloc"); }

  • cakephp secure link using html helper link method..

    - by Aaron
    What's the best way in cakephp to extend the html-link function so that I can tell it to output a secure(https) link? Right now, I've added my own secure_link function to app_helpers that's basically a copy of the link function but adding a https to the beginning. But it seems like there should be a better way of overriding the html-link method so that I can specify a secure option. http://groups.google.com/group/cake-php/browse%5Fthread/thread/e801b31cd3db809a I also started a thread on the google groups and someone suggested doing something like $html->link('my account', array('base' => 'https://', 'controller' => 'users')); but I couldn't get that working. Just to add, this is what is outputted when I have the above code. <a href="/users/index/base:https:/">my account</a> I think there's a bug in the cake/libs/router.php on line 850. There's a keyword 'bare' and I think it should be 'base' Though changing it to base doesn't seem to fix it. From what I gather, it's telling it to exclude those keys that are passed in so that they don't get included as parameters. But I'm puzzled as to why it's a 'bare' keyword and the only reason I can come up with is that it's a type.

  • How CPU finds ISR and distinguishes between devices

    - by ripunjay-tripathi-gmail-com
    I should first share all what I know - and that is complete chaos. There are several different questions on the topic, so please don't get irritated :). 1) To find an ISR, CPU is provided with a interrupt number. In x86 machines (286/386 and above) there is a IVT with ISRs in it; each entry of 4 bytes in size. So we need to multiply interrupt number by 4 to find the ISR. So first bunch of questions is - I am completely confused in mechanism of CPU receiving the interrupt. To raise an interrupt, firstly device shall probe for IRQ - then what ? The interrupt number travels "on IRQ" towards CPU? I also read something like device putting ISR address on data bus ; whats that then ? What is the concept of devices overriding the ISR. Can somebody tell me few example devices where CPU polls for interrupts? And where does it finds ISR for them ? 2) If two devices share an IRQ (which is very much possible), how does CPU differs amongst them ? What if both devices raise an interrupt of same priority simultaneously. I got to know there will be masking of same type and low priority interrupts - but how this communication happens between CPU and device controller? I studied the role of PIC and APIC for this problem, but could not understand. Thanks for reading. Thank you very much for answering.

  • Associations and the Grails webflow

    - by callie16
    Hi, it's my first time using webflows in Grails and I can't seem to solve this. I have 3 domain classes with associations that look something like this: class A { ... static hasMany = [ b : B ] ... } class B { ... static belongsTo = [ a : A ] static hasMany = [ c : C ] ... } class C { ... static belongsTo = [ b : B ] ... } Now, the GSP communicates with the controller via Javascript (due to my use of Dojo). When I try to remoteFunction a normal action, I can do something like this: def action1 = { def anId = params.id def currA = A.get(anId) def sample = currA.b?.c // I can get all the way to 'c' without any problems ... } However, I have a webflow and the contents of that action is in the webflow... It looks something like this: def someFlow = { ... someState { on("next") { def anId = params.id // this does NOT return a null value def currA = A.get(anId) // this does NOT return a null value def sample = currA.b // error already occurs here and I need to get 'c'! }.("somePage") ... } ... } In this case, it tells me that b doesn't exist... so I can't even get to 'c'. Any suggestions on what to do??? Thanks... getting real desperate...

  • My Core Animation block isn't working as I'd expect

    - by Alex Reynolds
    I have a UIView called activityView, which contains two subviews activityIndicator and cancelOperationsButton. These views are embedded in a XIB and wired up to my view controller. I have two methods that deal with activating (showing) and deactivating (hiding) these two subviews: - (void) enableActivityIndicator { [activityIndicator startAnimating]; [cancelOperationsButton setHidden:NO]; } - (void) disableActivityIndicator { [activityIndicator stopAnimating]; [cancelOperationsButton setHidden:YES]; } By themselves, these two methods work fine. To give this a bit of polish, I'd like to add an animation that fades these subviews in and out: - (void) enableActivityIndicator { [activityIndicator startAnimating]; [cancelOperationsButton setHidden:NO]; [UIView beginAnimations:@"fadeIn" context:nil]; [UIView setAnimationDelay:0.0f]; [UIView setAnimationDuration:1.0f]; [UIView setAnimationCurve:UIViewAnimationCurveEaseIn]; activityView.alpha = 1.0f; [UIView commitAnimations]; } - (void) disableActivityIndicator { [UIView beginAnimations:@"fadeOut" context:nil]; [UIView setAnimationDelay:0.0f]; [UIView setAnimationDuration:1.0f]; [UIView setAnimationCurve:UIViewAnimationCurveEaseOut]; activityView.alpha = 0.0f; [UIView commitAnimations]; [activityIndicator stopAnimating]; [cancelOperationsButton setHidden:YES]; } But the animations are not working — the subviews just show up or disappear without the parent view's alpha property having an effect on transparency. How should I write these methods to get the fade-in, fade-out effect I am after?

  • Ruby on Rails: how to get error messages from a child resource displayed?

    - by randombits
    I'm having a difficult time understanding how to get Rails to show explicitly the error messages that a child resource is failing on when I render an XML template. Hypothetically, I have the following classes: class School < ActiveRecord::Base has_many :students validates_associated :students end class Student < ActiveRecord::Base belongs_to :school validates_format_of :email, :with => /^([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})$/i, :message => "You must supply a valid email" end Now, in the controller, let's say we want to build a trivial API to allow us to add a new School with a student in it (again, I said, it's a terrible example, but plays its role for the purpose of the question) class SchoolsController < ApplicationController def create @school = School.new @student = school.students.build @student.email = "bad@email" respond_to do |format| if @school.save # some code else format.xml { render :xml => @school.errors, :status => :unprocessable_entity } end end end end Now the validation is working just fine, things die because the email doesn't match the regex that's set in the validates_format_of method in the Student class. However the output I get is the following: <?xml version="1.0" encoding="UTF-8"?> <errors> <error>Students is invalid</error> </errors> I want the more meaningful error message that I set above with validates_format_of to show up. Meaning, I want it to say: <error>You must supply a valid email</error> What am I doing wrong for that not to show up?

  • What's the best way to develop a debugging window for an ajax ASP.Net MVC application

    - by KallDrexx
    While developing my ASP.NET MVC, I have started to see the need for a debugging console window to assist in figuring out what is going right and wrong in my code. I read the last few chapters of the Pro Asp.net MVC book, and the author details how to use http modules to show page load/creation times and linq to sql query logs, both of which I definitely want to be able to see. However, since I am loading a lot of small sections of my page individually with ajax I don't want the debug information right there in the middle of my screen. So the idea I came up with was to have a separate browser window (open-able by a link or some javascript) with a console log, that can contain logged entries both from javascript and from the asp.net mvc run. The former should be relatively easy, but I'm having trouble coming up with a way to log the asp.net information in ajax requests. The direction I have been thinking of going is to create an httpmodule (like the Pro MVC book does), and have that module contain some that append the javascript's log to console calls with the messages. The issue I see with this is finding a way to get the log messages from the controller's action methods to the httpmodule's methods. The only way I see to do this is with a singleton, but I'm not sure if singletons are bad practice for a stateless web application. Furthermore, it seems like if I return json with my ajax calls (instead of pure html) then that won't work at all anyways and unless there is a way to add data to an existing json structure inside the httpmodule. How does everyone else handle this type of debugging in heavily ajax applications? For reference, the javascript library I am using is jquery.

  • zend_captcha always fails isValid()

    - by Grant Collins
    Hi, I've got an issue with Zend_Captcha always returning false when the page is submitted and the captcha's isValid() method is being called. It's driving my nuts because this as far as I am concerned should work. I start by declaring this at the top of the action function of the controller $captcha = new Zend_Captcha_Image('captcha', array( 'captcha' => array( 'name' => 'graduatesignupcaptcha', 'wordlen' => 6, 'font' => $this->config->captcha->font, 'imgDir' => $baseUrl.'/images/captcha/', 'imgUrl' => $this->config->webserver->name.'/images/captcha/', ) ) ); $captcha->setHeight(80) ->setTimeout(300); I do usual form validation and that all works, however it is when I come to validate that the value entered into form for the captcha it always returns false. //next we check the captcha text to ensure that the form is a person not a script $captchaText = $form->getElement('captchainput')->getValue(); $captchaId = $form->getElement('captchaid')->getValue(); //$captchaSession = new Zend_Session_Namespace('Zend_Form_Captcha_'.$captchaId); $captchaArray = array( 'id' => $captchaId, 'input' => $captchaText ); if(!$captcha->isValid($captchaArray)){ $log->log(implode(",",$captcha->getErrors()), Zend_Log::DEBUG); $form->getElement('captchainput')->setErrors(array('messages' => 'Bad security code')); $formFailed = true; } I've check to ensure that the id that I am getting and storing as a hidden element in my form match the image that is being generated but no matter what I do this always fails. Am I missing something simple here?? Or is there a better way of dealing with this?? Thanks,

  • In the iPad SplitView template, where's the code that specifies which views are to be used in the Sp

    - by Dr Dork
    In the iPad Programming Guide, it gives the following code example for specifying the two views (firstVC and secondVC) that will be used in the SplitView... - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { MyFirstViewController* firstVC = [[[MyFirstViewController alloc] initWithNibName:@"FirstNib" bundle:nil] autorelease]; MySecondViewController* secondVC = [[[MySecondViewController alloc] initWithNibName:@"SecondNib" bundle:nil] autorelease]; UISplitViewController* splitVC = [[UISplitViewController alloc] init]; splitVC.viewControllers = [NSArray arrayWithObjects:firstVC, secondVC, nil]; [window addSubview:splitVC.view]; [window makeKeyAndVisible]; return YES; } but when I actually create a new SplitView project in Xcode, I don't see any code that specifies which views should be added to the SplitView. Here's the code from the SplitView template... - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // Override point for customization after app launch rootViewController.managedObjectContext = self.managedObjectContext; // Add the split view controller's view to the window and display. [window addSubview:splitViewController.view]; [window makeKeyAndVisible]; return YES; } Thanks in advance for all your help! I'm going to continue researching this question right now.

  • Making one of a group of similar form fields required in CakePHP

    - by Pickledegg
    I have a bunch of name/email fields in my form like this: data[Friend][0][name] data[Friend][1][name] data[Friend][2][name] etc. and data[Friend][0][email] data[Friend][1][email] data[Friend][2][email] etc. I have a custom validation rule on each one that checks to see if the corresponding field is filled in. Ie. if data[Friend][2][name] then data[Friend][2][email] MUST be filled in. FYI, heres what one of the two rules look like: My form validation rule: ( I have an email validation too but that's irrelevant here) 'name' => array( 'checkEmail' => array( 'rule' => 'hasEmail', 'message' => 'You must fill in the name field', 'last' => true ) ) My custom rule code: function hasEmail($data){ $name = array_values($data); $name = $name[0]; if(strlen($name) == 0){ return empty($this->data['Friend']['email']); } return true; } I need to make it so that one of the pairs should be filled in as a minimum. It can be any as long as the indexes correspond. I can't figure a way, as if I set the form rule to be required or allowEmpty false, it fails on ALL empty fields. How can I check for the existence of 1 pair and if present, carry on? Also, I need to strip out all of the remaining empty [Friend] fields, so my saveAll() doesn't save a load of empty rows, but I think I can handle that part using extract in my controller. The main problem is this validation. Thanks.

  • UITableView and UITableCellView, how does this work with core plot ?

    - by Luc
    Hello, I'm very new to iPhone programming, and I'm currently following tutos to understand the whole thing. I've been able to do what I needed (retrive data from a JSON http server, parse them with YAJL and plot the data in core plot). I have done this in a "simple" view where I have added a UILayerHostingView as requested by core-plot. I am now trying to follow this tuto: http://blogs.remobjects.com/blogs/mh/2010/01/26/p973 but I am missing the first part regarding the views... My understanding is that I need to create a view with a UITableView first. Then add a UITableCellView to make the first cell be able to contain the graph ? Is this right ? Where does the method "(id)initWithStyle:(UITableViewCellStyle)style" come from ? For my needs, only the first cell needs to contain a graph, I will put some other info in the other cells. As for now, I have created a new GraphListViewController, in the corresponding view I have added a listview but I do not see any auto generated methods regading cell customisation ? Do I need to implements DataSource in this controller and manually add some customisation methods ? Do I need to add a UITagbleViewCell to this UITableViewTable within IB ? Hope I am not getting to confusing... Thanks a lot for your help, Best Regards, Luc

  • Passenger error message I can't figure out

    - by Sam Kong
    Hi, I am testing Rails 3 on DreamHost which just installed Rails 3. I created a simple controller and it failed. Browser shows 500 error (Internal Server Error) and the log shows the following message. Could not find i18n-0.5.0 in any of the sources Try running `bundle install`. *** Exception EOFError in spawn manager (Unexpected end-of-file detected.)

  • Rails : fighting long http response times with ajax. Is it a good idea? Please, help with implementa

    - by baranov
    Hi, everybody! I've googled some tutorials, browsed some SO answers, and was unable to find a recipe for my problem. I'm writing a web site which is supposed to display almost realtime stock chart. Data is stored in constantly updating MySQL database, I wrote a find_by_sql query code which fetches all the data I need to get my chart drawn. Everything is ok, except performance - it takes from one second to one minute for different queries to fetch all the data from the database, this time includes necessary (My)SQL-server side calculations. This is simply unacceptable. I got the following idea: if the data is queried from the MySQL server one point a time instead of entire dataset, it takes only about 1-100ms to get an individual point. I imagine the data fetch process might be browser-driven. After the user presses the button in order to get a chart drawn, controller makes one request to the database and renders, say, a progress bar, say 1% ready. When the browser gets the response, it immediately makes an (ajax) request, and the server fetches the next piece of data and renders "2%". And so on, until all the data is ready and the server displays the requested chart. Could this be implemented in rails+js, is there a tutorial for solving a similar problem on the Web? I suppose if the thing is feasible at all, somebody should have already done this before. I have read several articles about ajax, I believe I do understand general principles, but never did nontrivial ajax programming myself. Thanks for your time!

  • Why can't I initialize a class through a setter?

    - by Rob emenaker
    If I have a custom class called Tires: #import <Foundation/Foundation.h> @interface Tires : NSObject { @private NSString *brand; int size; } @property (nonatomic,copy) NSString *brand; @property int size; - (id)init; - (void)dealloc; @end ============================================= #import "Tires.h" @implementation Tires @synthesize brand, size; - (id)init { if (self = [super init]) { [self setBrand:[[NSString alloc] initWithString:@""]]; [self setSize:0]; } return self; } - (void)dealloc { [super dealloc]; [brand release]; } @end And I synthesize a setter and getter in my View Controller: #import <UIKit/UIKit.h> #import "Tires.h" @interface testViewController : UIViewController { Tires *frontLeft, *frontRight, *backleft, *backRight; } @property (nonatomic,copy) Tires *frontLeft, *frontRight, *backleft, *backRight; @end ==================================== #import "testViewController.h" @implementation testViewController @synthesize frontLeft, frontRight, backleft, backRight; - (void)viewDidLoad { [super viewDidLoad]; [self setFrontLeft:[[Tires alloc] init]]; } - (void)dealloc { [super dealloc]; } @end It dies after [self setFrontLeft:[[Tires alloc] init]] comes back. It compiles just fine and when I run the debugger it actually gets all the way through the init method on Tires, but once it comes back it just dies and the view never appears. However if I change the viewDidLoad method to: - (void)viewDidLoad { [super viewDidLoad]; frontLeft = [[Tires alloc] init]; } It works just fine. I could just ditch the setter and access the frontLeft variable directly, but I was under the impression I should use setters and getters as much as possible and logically it seems like the setFrontLeft method should work. This brings up an additional question that my coworkers keep asking in these regards (we are all new to Objective-C); why use a setter and getter at all if you are in the same class as those setters and getters.

  • Crash on iOS when system purges memory and closes a UIViewController

    - by Amiramix
    My application is crashing when one of the views is purged from memory because of low-memory condition. At least this is what I understand from the crashlog. It happens on numerous screens but only when opening a Facebook dialog (using the Facebook SDK). Basically, looks like the system sometimes runs out of memory when we need to present a Facebook dialog (e.g. to let user post something on the Facebook timeline). Date/Time: 2012-03-14 19:47:33.819 +0000 OS Version: iPhone OS 5.1 (9B176) Report Version: 104 Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Codes: KERN_INVALID_ADDRESS at 0x30000008 Crashed Thread: 0 Thread 0 name: Dispatch queue: com.apple.main-thread Thread 0 Crashed: 0 libobjc.A.dylib 0x30f2bf78 objc_msgSend + 16 1 MyApp 0x00003c0e -LTBaseViewController viewDidUnload (LTBaseViewController.m:145) 2 MyApp 0x00004ea2 -LTBaseTableViewController viewDidUnload (LTBaseTableViewController.m:90) 3 UIKit 0x33766bd8 -[UIViewController unloadViewForced:] + 244 4 UIKit 0x338ae492 -[UIViewController purgeMemoryForReason:] + 58 5 Foundation 0x3071a4f8 __57-NSNotificationCenter addObserver:selector:name:object:_block_invoke_0 + 12 6 CoreFoundation 0x30e95540 ___CFXNotificationPost_block_invoke_0 + 64 7 CoreFoundation 0x30e21090 _CFXNotificationPost + 1400 8 Foundation 0x3068e3e4 -NSNotificationCenter postNotificationName:object:userInfo: + 60 9 Foundation 0x3068fc14 -NSNotificationCenter postNotificationName:object: + 24 10 UIKit 0x3387926a -UIApplication _performMemoryWarning + 74 11 UIKit 0x33879364 -UIApplication _receivedMemoryNotification + 168 12 libdispatch.dylib 0x36a12252 _dispatch_source_invoke + 510 13 libdispatch.dylib 0x36a0fb1e _dispatch_queue_invoke$VARIANT$up + 42 14 libdispatch.dylib 0x36a0fe64 _dispatch_main_queue_callback_4CF$VARIANT$up + 152 15 CoreFoundation 0x30e9c2a6 __CFRunLoopRun + 1262 16 CoreFoundation 0x30e1f49e CFRunLoopRunSpecific + 294 17 CoreFoundation 0x30e1f366 CFRunLoopRunInMode + 98 18 GraphicsServices 0x33fb6432 GSEventRunModal + 130 19 UIKit 0x336f5e76 UIApplicationMain + 1074 20 MyApp 0x00004818 main (main.m:16) 21 MyApp 0x000023b4 0x1000 + 5044 I checked and there are almost no memory leaks, e.g. when testing the app for an hour the total memory leaked was around 2-3Kb caused by some string-copying libraries. So I don't believe this is caused by the application. I guess that when the phone is not restarted for some time there are applications running in the background and when using Facebook SDK the memory becomes a problem and the system tries to recover the memory from random applications, including my application. My question is, how can I prevent this crash from happening? How should I handle unloadViewForced on a view controller to make the app more robust in low-memory conditions? And lastly, am I right that this crashlog suggests the crash occurred because the system tried to free memory and my application didn't handle it properly? Any help greatly appreciated.
