  • @synthesize with UITabBarController?

    - by fuzzygoat
    I am curious if there is a good reason I should / should not be using @synthesize for the tabBarController below, or does it not matter? @implementation ScramAppDelegate @synthesize window; @synthesize tabBarController; -(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { [self setTabBarController:[[UITabBarController alloc] init]]; [window addSubview:[tabBarController view]]; [window makeKeyAndVisible]; return YES; } -(void)dealloc { [tabBarController release]; [self setTabBarController: nil]; [window release]; [super dealloc]; } OR @implementation ScramAppDelegate @synthesize window; -(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { tabBarController = [[UITabBarController alloc] init]; [window addSubview:[tabBarController view]]; [window makeKeyAndVisible]; return YES; } -(void)dealloc { [tabBarController release]; [window release]; [super dealloc]; } cheers Gary

  • Drupal Views Bonus Pack export issue

    - by evanmcd
    Hi, In trying to solve the problem of getting data from Drupal into XML, I found the Views Bonus Pack module, which with a little figuring out works great. Except... When setting the Style property in the Basic settings of Feed view to XML file no items show up unless I am authenticated. If I log in, I see all the entries. If I log out, I see only <xml> <node/> </xml> The Access setting is set to unrestricted in both the Defaults and the Feed view. Anybody have any ideas as to how to fix this? Thanks a lot.

  • WPF TreeView PreviewMouseDown on TreeViewItem

    - by imekon
    If I handle the PreviewMouseDown event on TreeViewItem, I get events for everything I click on that TreeViewItem include the little +/- box to the left (Windows XP). How can I distinguish that? I tried the following: // We've had a single click on a tree view item // Unfortunately this is the WHOLE tree item, including the +/- // symbol to the left. The tree doesn't do a selection, so we // have to filter this out... MouseDevice device = e.Device as MouseDevice; // This is bad. The whole point of WPF is for the code // not to know what the UI has - yet here we are testing for // it as a workaround. Sigh... // This is broken - if you click on the +/- on a item, it shouldn't // go on to be processed by OnTreeSingleClick... ho hum! if (device.DirectlyOver.GetType() != typeof(Path)) { OnTreeSingleClick(sender); } What I'm after is just single click on the tree view item excluding the extra bits it seems to include.

  • Simple CanCan problem

    - by sscirrus
    I have just started with CanCan and here's a sample of the code: # Ability.rb def initialize(user) user ||= User.new can :read, Link end # view.html.erb <% if can? :read, @link %> ... <% end %> This is from the github repo for CanCan but this doesn't seem to work (it returns false and stops the ... code from running). When I change the view to <% if can? :read, Link %>, it works. But, this is different to the CanCan readme. Do you know where I'm going wrong here?

  • Why can't I store a float value - it's always zero!

    - by just_another_coder
    I have a view controller that is created by the app delegate - it's the first one shown in the app. In its interface I declare float lengthOfTime; I also set it as a property: @property (nonatomic) float lengthOfTime; And in it's implemetation: @synthesize lengthOfTime; In the class viewDidLoad method, I set the value: self.lengthOfTime = 3.0f; However, after this, the value is always zero. No errors, no compile warnings, nothing. Just zero. The class is instantiated, it is showing in the view, so I'm pretty sure it's not a nil reference. I've searched all over Google and can't figure it out. What's going on?!? :(

  • UITabBarController "More" tab issues

    - by codemonkey
    I've got a UITabBarController with 7 tabs. Each of the 7 tabs has its own UINavigationController and customizes its toolbar. When a view is loaded via the UITabBarController's "More" menu its custom toolbar isn't appearing. If i switch the order of the views around so that the same view is now accessible from the UITabBar without going through the "More" menu then the custom toolbar shows up like it's supposed to. Is there a way to customize a NavigationController's toolbar when that NavigationController is loaded via the "More" menu of a TabBarController? I'm actually also interested in replacing the "More" menu navigation controller with my own custom one on views loaded via the "More" menu... not sure whether that's even possible. Any feedback will be appreciated.

  • Semantic Fish-eye zoom on table cells in UIKit?

    - by niblha
    How would I go about implementing a table view that looks and works something as illustrated in the link below, with UIKit for the iPhone? http://img442.imageshack.us/img442/4177/uifisheyeview.png I was thinking of using UITableView, and was looking a bit at the UITableViewDelegate methods tableView:willDisplayCell:forRowAtIndexPath: tableView:heightForRowAtIndexPath: But it seems as the UITableView will modify the cell frames after these methods are called and just before the cells are drawn? Maybe skipping the UITableView and go straight for some subclassing of a UIScrollView would be a better approach? So my question is basically that I would just like some overall thought in what might be the best ways to use existing UIKit components to implement this type of table view.

    - by VXtreme
    I am using MPMoviePlayerController for playing the media . I want to set the image at the background of the player.The image is set accordingly but when i set the bounds for the image then the image is not set according to bounds . I have tried following code: UIImageView *imageView=[[UIImageView alloc]initWithImage:[operationControl getCoverImage:stringId]]; imageView.bounds=CGRectMake(0, 100, 200, 200); [moviePlayer.backgroundView addSubview:imageView]; [moviePlayer.backgroundView setBackgroundColor:[UIColor purpleColor]]; moviePlayer.controlStyle = MPMovieControlStyleDefault; moviePlayer.shouldAutoplay = YES; [moviePlayer setScalingMode:MPMovieScalingModeAspectFit]; [self.view addSubview:moviePlayer.view]; [moviePlayer setFullscreen:YES animated:YES];

  • Django: Geocoding an address on form submission?

    - by User
    Trying to wrap my head around django forms and the django way of doing things. I want to create a basic web form that allows a user to input an address and have that address geocoded and saved to a database. I created a Location model: class Location(models.Model): address = models.CharField(max_length=200) city = models.CharField(max_length=100) state = models.CharField(max_length=100, null=True) postal_code = models.CharField(max_length=100, null=True) country = models.CharField(max_length=100) latitude = models.DecimalField(max_digits=18, decimal_places=10, null=True) longitude = models.DecimalField(max_digits=18, decimal_places=10, null=True) And defined a form: class LocationForm(forms.ModelForm): class Meta: model = models.Location exclude = ('latitude','longitude') In my view I'm using form.save() to save the form. This works and saves an address to the database. I created a module to geocode an address. I'm not sure what the django way of doing things is, but I guess in my view, before I save the form, I need to geocode the address and set the lat and long. How do I set the latitude and longitude before saving?

  • Using setSourceType with image picker up hides status bar

    - by Aaron
    I am pretty sure this is a bug but I thought I would check. I used the camera overlay to add a button so that on the iphone a user can switch from the camera view to the photo library. When button is taped the source type switches fine but the status bar is missing from the photo library. Throughout the rest of that session the status bar remains missing from all views evet thougth isStatusBarHidden reports NO. This is how the camera overlay view is created if (cameraOverlayView == nil) { [[NSBundle mainBundle] loadNibNamed:@"CameraOverlayView" owner:self options:nil]; } If camera is available this is when I set source type and add overlay if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) { [imagePicker setSourceType:UIImagePickerControllerSourceTypeCamera]; [imagePicker setCameraOverlayView:cameraOverlayView]; } Here is the action statement to change source type. (IBAction)selectImage; { [imagePicker setSourceType:UIImagePickerControllerSourceTypePhotoLibrary]; } If I don't tap the button on the overlay there is no problem with the status bar. PS. I did submit a bug report on this.

  • UIScrollView: Is 806k Image too much too handle? (Crash, out of memory)?

    - by Jordan
    I'm loading a 2400x1845 png image into a scroll view. The program crashes out of memory, is there a better way to handle this? mapScrollView is an UIScrollView in IB, along with a couple of UIButtons. -(void)loadMapWithName:(NSString *)mapName { NSString* bundlePath = [[NSBundle mainBundle] bundlePath]; UIImage *image = [UIImage imageWithContentsOfFile:[NSString stringWithFormat:@"%@/path/%@", bundlePath, [maps objectForKey:mapName]]]; UIImageView *imageView = [[UIImageView alloc] initWithImage:image]; CGSize imgSize = image.size; mapScrollView.contentSize = imgSize; [mapScrollView addSubview:imageView]; [imageView release]; [self.view addSubview:mapScrollView]; }

  • Why are my ActiveRecord class instance variables disappearing after the first request in development

    - by Paul C
    I have a class instance variable on one of my AR classes. I set its value at boot with an initializer and, after that, never touch it again except to read from it. In development mode, this value disappears after the first request to the web server. However, when running tests, using the console or running the production server this does not happen. # The AR class class Group < ActiveRecord::Base class << self attr_accessor :path end end # The initializer Group.path = File.join(RAILS_ROOT, "public", "etc") # First request in a view %p= Group.path #=> "/home/rails/app/public/etc" # Second request in a view %p= Group.path #=> nil Is there something about development mode that nukes instance variables from classes with each request? If so, is there a way to disable this for specific variables or classes?

  • Pinterest Gridview implementation on iOS

    - by Amal
    I want to implement a grid view like the one in Pinterest I thought about implementing as 3 table views. But I was not able to scroll them together well. When I implemented the scrollViewDidScroll and set the contentOffset for the table views other the scrollView , the scrolling became slow and unusable. Another implementation I did was of was having a set of images to load and calling the viewDraw function in scrollViewDidScroll. THe ViewDraw function just draws the necessary images and removes the rest of the images from the memory which were already drawn but wont be visible . this too makes the ScrollView Scrolling slow. And another issue with it is that there are white(background color) patches before the images are drawn. What should be the best way to implement this grid view ?

  • In an Android TextView, is it possible to insert paragraphs?

    - by johnrock
    Below is an example of the type of problem that I have. I have data in a pojo that I need to display in a textview... the data has pseudo code that denotes each paragraph with [p] I would like to somehow parse the [p]'s into paragraphs when they are displayed in the textview. Can this be done? Is there something I can substitute for the [p] that will make a new paragraph in the textview? Question question = new Question(); question.setText("Here is the first paragraph.[p] And this should be the second."); TextView view = (TextView) findViewById(R.id.qtext); view.setText(question.getParsedText());

  • Dojo slider: update value dynamically

    - by xApple
    I am building an application where the user browses certain objects by scrolling and zooming. To change the zoom level I have successfully implemented a "dijit.form.HorizontalSlider" object. Every time the user changes the position of the silder, I can catch the "onChange" call and do something with that. However, the user can also zoom-in by double clicking inside the view zone, at which point the slider should change position automatically to reflect the new zoom level. My question is the following: what function or method should I call in my javascript to update the position of a dojo silder ? Here is the code that creates the silder object: var zoomSlider = new dijit.form.HorizontalSlider({ name: "zoom_slider", id: "zoom_slider", value: 0, minimum: 0, maximum: 19, discreteValues: 20, intermediateChanges: false, style: "width: 160px;", onChange: function(value) { brwsr.view.zoomTo(value); } }, "zoom_slider"); navbox_silder.appendChild(zoomSlider.domNode);

  • How to extract delegates from ViewController class?

    - by adranle
    Hi I have the problem that my view controller class has too many delegates and starts to get big. I want to write the delegates in separate classes to keep the view controller class small. For delegates that are programmatically created (like UIAlertViewDelegate) I could do it easily. The problem is in the delegates assigned in Interface Builder. How can I tell the IB to assign, for example, another class as the UITableViewDelegate or UITableViewDataSource? Or how to choose another IBAction method for a Touch UP inside Event on a button? One solution would be to delete the connections from IB and write them programmatically at ViewDidLoad, but since I have a lot of ViewControllers, this would take a long time. any other ideas?

  • Silverlight Pixel Shader resource "not found"; what should the URI be?

    - by Grank
    So I've written and compiled an HLSL pixel shader with Shazzam, placed the resulting .ps file in my project, and am trying to instantiate it. No matter what URI I put, Blend tells me that the resource can't be found whenever I try to view any xaml designer, and Visual Studio just shows me a blank page, both in design view and if I try to run the application. This is a Silverlight 4 SketchFlow project, in Blend 4 RC and Visual Studio 2010. I've tried both Resource and EmbeddedResource as the Build Action for the .ps file, neither make any difference (I'm pretty sure it's supposed to be set to Resource). I've tried the following URI formats: "ShaderFileName.ps" "/ShaderFileName.ps" "AssemblyName;component/ShaderFileName.ps" "/AssemblyName;component/ShaderFileName.ps" I also tried moving the shader file from the Screens assembly to the root assembly (that's how SketchFlow projects are created) and that didn't help either. Anyone have any thoughts?

  • NSArraycontroller selectionIndexes bindings

    - by Michael Scherbaum
    Hi all, I have the following set-up: A Window that has a splitView in which I display I NSCollectionView in the left view and a detailView in the right view. Both views are set-up in separate xibs. Furthermore I have a Datacontroller (of class NSArrayController) that manages a mutable Array of NSMutableDictionaries (moviesForChoice). The dataController is set-up as application delegate. The movie objects in the array have properties like (name, plot, genre etc.) so far so good... In the xib for the NScollectionview I bound a NSArraycontroller content property to my datacontroller via Application.delegate.moviesForChoice The collectionView accesses the arraycontroller.arrrangedObjects and arraycontroller.selectionIndexes. This works fine the contents are displayed and the selection works fine in the collectionview (my collectionviewItem renders a selection color) In the xib for the detailView I want to display information for the selected object in the collectionview. Therefore I also added an arraycontroller to the xib, bound the content aray to Application.delegate.moviesForChoice and bound the NSTextfields in the view to e.g. arraycontroller.selection.name Here comes my issue: everytime I open the window with the two xibs, my collectionview displays all movies that are for choice correctly, and the detailview displays the information for the 1st object in my collectionview. Whenever I click on a different movie in the collectionView the res. item renders a selection color, but the detailView doesn't update. My understanding of it would be that the DataController is not informed about updates in the selectionIndexes and can therefore not trigger an update in the detailView. Correct me if I'm wrong... To remedy this I tried to bind the selectionIndexes property of the arraycontroller in the collectionView xib to Application.delegate.moviesForChoice.selecionIndexes but this failed with: addObserver:forKeyPath:options:context:] is not supported. Key path: selectionIndexes I could imagine that this means that the datacontroller is not KVO compliant for my Array moviesForChoice, but I implemented the following methods for it: -(void)insertObject:(NSDictionary *)dict inMoviesForChoiceAtIndex:(NSUInteger)index { [moviesForChoice insertObject:dict atIndex:index]; } -(void)removeObjectFromMoviesForChoiceAtIndex:(NSUInteger)index { [moviesForChoice removeObjectAtIndex:index]; } -(void)setMoviesForChoice:(NSMutableArray *)a { moviesForChoice = a; } -(NSArray*)moviesForChoice { return moviesForChoice; } -(NSUInteger)countOfMoviesForChoice { return [moviesForChoice count]; } - (void)addMovieForChoiceObject:(Movie *)anObject { [moviesForChoice addObject:anObject]; } So where am I wrong? How do I correctly bind to the selectionIndexes? You help is much appreciated! M

  • Tomcat + Spring + CI workflow

    - by ex3v
    We're starting our very first project with Spring and java web stack. This project will be mainly about rewriting quite large ERP/CRM from Zend Framework to Java. Important factor in my question is that I come from php territory, where things (in terms of quality) tend to look different than in java world. Fatcs: there will be 2-3 developers, at least one of developers uses Windows, rest uses Linux, there is one remote linux-based machine, which should handle test and production instances, after struggling with buggy legacy code, we want to introduce good programming and development practices (CI, tests, clean code and so on) client: internal, frequent business logic changes, scrum, daily deployments What I want to achieve is good workflow on as many development stages as possible (coding - commiting - testing - deploying). The problem is that I've never done this before, so I don't know what are best practices to do this. What I have so far is: developers code locally, there is vagrant instance on every development machine, managed by puppet. It contains the same linux, jenkins and tomcat versions as production machine, while coding, developer deploys to vagrant machine, after local merge to test branch, jenkins on vagrant handles tests, when everything is fine, developer pushes commits and merges jenkins on remote machine pulls commit from test branch, runs tests and so on, if everything looks green, jenkins deploys to test tomcat instance Deployment to production is manual (altough it can be done using helping scripts) when business logic is tested by other divisions and everything looks fine to client. Now, the real question: does above make any sense? Things that I'm not sure about: Remote machine: won't there be any problems with two (or even three, as jenkins might need one) instances of same app on tomcat? Using vagrant to develop on php environment is just vise. Isn't this overkill while using Tomcat? I mean, is there higher probability that tomcat will act the same on every machine? Is there sense of having local jenkins on vagrant?

  • Rotation of ViewController in TabbarController

    - by hanno
    I have a custom UIViewController in a UITabbarController and want to respond to rotation events. When a rotation occurs, the tabbarcontroller and the viewcontroller get rotated. However, the view in the viewcontroller doesn't get redrawn properly: the layout doesn't autoresize and it is black on parts of the screen. The strange thing is that it works when I go to another tab and the back again to my original viewcontroller. What could possibly be wrong? I checked that didRotateFromInterfaceOrientation:fromInterfaceOrientation is being called. However, the view.frame.size values are still the old ones from before the rotation. That's probably not correct.
