• UIWebView in multithread ViewController

  - by Tao

  I have a UIWebView in a viewcontroller, which has two methods as below. The question is if I pop out(tap back on navigation bar) this controller before the second thread is done, the app will crash after [super dealloc], because "Tried to obtain the web lock from a thread other than the main thread or the web thread. This may be a result of calling to UIKit from a secondary thread.". Any help would be really appreciated. -(void)viewDidAppear:(BOOL)animated { [super viewWillAppear:animated]; NSInvocationOperation *operation = [[NSInvocationOperation alloc] initWithTarget:self selector:@selector(load) object:nil]; [operationQueue addOperation:operation]; [operation release]; } -(void)load { [NSThread sleepForTimeInterval:5]; [self performSelectorOnMainThread:@selector(done) withObject:nil waitUntilDone:NO]; }

• Editing a UIViewController from another class.

  - by Guy

  I am trying to programmatically change the user interface of a UIViewController from another NSObject class. The problem is that I am unsure of how to access the UIViewController's view from the NSObject class. So for example, in my NSObject class, I say something like: self.view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)]; self.view.backgroundColor = [UIColor yellowColor]; but I keep getting errors saying "Request for member "view" in something not a strut or union." Is there something I need to allow my NSObject class to see my UIViewController? Thanks!

• UISlider disappearing when calling setValue with 0

  - by Kai

  I have several UISliders in my application which all work fine until I call the following code: ... frame = CGRectMake(43, 210, 201, 23); mySlider = [[UISlider alloc] initWithFrame:frame]; [mySlider addTarget:self action:@selector(sliderUpdate:) forControlEvents:UIControlEventValueChanged]; mySlider.minimumValue = 0.0; mySlider.maximumValue = 1.0; mySlider.continuous = YES; tempNum = [myArray objectAtIndex:2]; mySlider.value = [tempNum floatValue]; // only breaks if value is 0 [self.view addSubview:mySlider]; ... For some reason the slider doesn't show up unless mySlider.value is set to greater than 0. The only workaround I've found so far is to set it to an extremely small value (such as 0.000000001), which makes the slider appear as expected. Does anyone have any idea why this might be happening and how it can be fixed?

• python fdb save huge data from database to file

  - by peter

  I have this script SELECT = """ select coalesce (p.ID,'') as id, coalesce (p.name,'') as name, from TABLE as p """ self.cur.execute(SELECT) for row in self.cur.itermap(): xml +=" <item>\n" xml +=" <id>" + id + "</id>\n" xml +=" <name>" + name + "</name>\n" xml +=" </item>\n\n" #save xml to file here f = open... and I need to save data from huge database to file. There are 10 000s (up to 40000) of items in my database and it takes very long time when script runs (1 hour and more) until finish. How can I take data I need from database and save it to file "at once"? (as quick as possible? I don't need xml output because I can process data from output on my server later. I just need to do it as quickly as possible. Any idea?) Many thanks!

• @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

• python json_encode throws KeyError exception

  - by MattM

  In a unit test case that I am running, I get a KeyError exception on the 4th json object in the json text below. I went through the sub-objects and found that it was the "cpuid" object that is the offending object, but I am completely at a loss as to what is wrong with the formatting. response = self.app.post( '/machinestats', params=dict(record=self.json_encode([ {"type": "crash", "instance_id": "xxx", "version": "0.2.0", "build_id": "unknown", "crash_text": "Gah!"}, {"type": "machine_info", "machine_info": "I'm awesome.", "version": "0.2.0", "build_id": "unknown", "instance_id": "yyy"}, {"machine_info": "Soup", "crash_text": "boom!", "version": "0.2.0", "build_id": "unknown", "instance_id": "zzz", "type": "crash"}, {"build_id" : "unknown", "cpu_brand" : "intel", "cpu_count" : 4, "cpuid": { "00000000": {"eax" :123,"ebx" :456, "ecx" :789,"edx" :321}, "00000001": {"eax" :123,"ebx" :456, "ecx" :789,"edx" :321}}, "driver_installed" : True, "instance_id" : "yyy", "version" : "0.2.0", "machine_info" : "I'm awesome.", "os_version" : "linux", "physical_memory_mib" : 1024, "product_loaded" : True, "type" : "machine_info", "virtualization_advertised" : True} ])))

• How to create a controllable flip effect (flip as far (and fast) as you drag) of an UIView

  - by allisone

  I have a card (a flashcard you could say) What I can do: On fingersweeping over the flashcard the card gets turned. It's happening by detecting touchesBegan and touchesMoved and then I do stuff like [UIView beginAnimations:@"View Flip" context:nil]; [UIView setAnimationDuration:0.5]; [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; if (left) { [UIView setAnimationTransition: UIViewAnimationTransitionFlipFromLeft forView:self.flashCardView cache:YES]; }else{ [UIView setAnimationTransition: UIViewAnimationTransitionFlipFromRight forView:self.flashCardView cache:YES]; } What I can't do (but want to): I want to somehow drag the flip. Imagine this, you have a flashcard and you think you know the answer, you start flipping the card around because you want to see if you are correct, but then... no stop... you hesitate, turn back the card to the way it was, rethink, get the real answer and then finally flip to see that you were right to hesitate. Now I only have: once you start flipping, you can't stop it.

• Python module seeing a full list as empty in another module

  - by Nick

  I'm working on a pygame project and have the main engine layed out. The problem is I hit a bug that I just can not seem to figure out. What happens is one module can't read a variable from another module. It's not that the variable can't be read, it just sees an empty list instead of what it really is. Instead of posting the entire source code I reproduced the bug in two small snippets that hopefully a skillful python-ist can interpret in his\her head. Code: main.py (This is the file that gets run) import screen screens = [] #A stack for all the game screens def current_screen(): #return a reference to the current screen return screens[-1] def play(): print'play called' current_screen().update() if __name__=='__main__': screens.append(screen.Screen()) play() screen.py import main class Screen: def __init__(self): print'screen made' def update(self): print main.screens #Should have a reference to itself in there Thanks!

• Implementing a multimap in Swift with Arrays and Dictionaries

  - by stuffy

  I'm trying to implement a basic multimap in Swift. Here's a relevant (non-functioning) snippet: class Multimap<K: Hashable, V> { var _dict = Dictionary<K, V[]>() func put(key: K, value: V) { if let existingValues = self._dict[key] { existingValues += value } else { self._dict[key] = [value] } } } However, I'm getting an error on the existingValues += value line: Could not find an overload for '+=' that accepts the supplied arguments This seems to imply that the value type T[] is defined as an immutable array, but I can't find any way to explicitly declare it as mutable. Is this possible in Swift?

• UIActionSheet cancel button strange behaviour

  - by nevan

  I have a UIBarButtonItem opening an action sheet to offer users choices about what to do. Everything works as expected unless I try to click on the "Cancel" button. The target of the button appears to have moved up from where it should be. I can only activate it by clicking somewhere in the middle of the "Cancel" and "Ok" buttons. I've tried at action sheets in other applications and they work fine, so it's not just my big thumb. The action sheet is opening in a UIViewController - (void)showOpenOptions { UIActionSheet *sheet = [[UIActionSheet alloc] initWithTitle:NSLocalizedString(@"Open link in external application?", @"Open in external application") delegate:self cancelButtonTitle:NSLocalizedString(@"Cancel", @"Cancel") destructiveButtonTitle:NSLocalizedString(@"Open Link", @"Open Link") otherButtonTitles:nil]; [sheet showInView:self.view]; [sheet release]; }

• Is there a recommended command for "hg bisect --command"?

  - by blokeley

  I have an emergent bug that I've got to track down tomorrow. I know a previous hg revision which was good so I'm thinking about using hg bisect. However, I'm on Windows and don't want to get into DOS scripting. Ideally, I'd be able to write a Python unit test and have hg bisect use that. This is my first attempt. bisector.py #!/usr/bin/env python import sys import unittest class TestCase(unittest.TestCase): def test(self): #raise Exception('Exception for testing.') #self.fail("Failure for testing.") pass def main(): suite = unittest.defaultTestLoader.loadTestsFromTestCase(TestCase) result = unittest.TestResult() suite.run(result) if result.errors: # Skip the revision return 125 if result.wasSuccessful(): return 0 else: return 1 if '__main__' == __name__: sys.exit(main()) Perhaps I could then run: hg bisect --reset hg bisect --bad hg bisect --good -r 1 hg bisect --command=bisector.py Is there a better way of doing it? Thanks for any advice.

• converting NSTimer running not on main runloop to GCD

  - by Justin Galzic

  I have a task that runs periodically and it was originally designed to run on a separate run loop than the main runloop using NSThread and NSTimer. What's the best way to adapt this to take advantage of GCD? Current code: -(void)initiateSomeTask { [NSThread detachNewThreadSelector:@selector(startTimerTask) toTarget:self withObject:nil]; } -(void)startTimerTask { // We won't get back the main runloop since we're on a new thread NSRunLoop *myRunLoop = [NSRunLoop currentRunLoop]; NSPort *myPort = [NSMachPort port]; [myRunLoop addPort:myPort forMode:NSDefaultRunLoopMode]; NSTimer *myTimer = [NSTimer timerWithTimeInterval:10 /* seconds */ target:self selector:@selector(doMyTaskMethod) userInfo:nil repeats:YES]; [myRunLoop addTimer:myTimer forMode:NSRunLoopCommonModes]; [myRunLoop run]; } Is there anything I can do besides replace detachNewThreadSelector with dispatch_async?

• dealloc on Background Thread

  - by Mark Brackett

  Is it an error to call dealloc on a UIViewController from a background thread? It seems that UITextView (can?) eventually call _WebTryThreadLock which results in: bool _WebTryThreadLock(bool): Tried to obtain the web lock from a thread other than the main thread or the web thread. This may be a result of calling to UIKit from a secondary thread. Background: I have a subclassed NSOperation that takes a selector and a target object to notify. -(id)initWithTarget:(id)target { if (self = [super init]) { _target = [target retain]; } return self; } -(void)dealloc { [_target release]; [super dealloc]; } If the UIViewController has already been dismissed when the NSOperation gets around to running, then the call to release triggers it's dealloc on a background thread.

• How can I access data that's stored in my App Delegate from my various view controllers?

  - by BeachRunnerJoe

  This question is similar to this other post, but I'm new to iPhone development and I'm getting used to the good practices for organizing my data throughout my app. I understand the ApplicationDelegate object to be the best place to manage data that is global to my app, correct? If so, how can I access data that's stored in my App Delegate from various view controllers? Specifically, I have an array of table section titles for my root table view controller created as such... appdelegate.m sectionTitles = [[NSArray alloc] initWithObjects: @"Title1", @"Title2", @"Title3", nil]; rootViewController.appDelegate = self; and I need to access it throughout the different views of my app, like such... rootviewcontroller.m NSUInteger numSections = [self.appDelegate.sectionTitles count]; Is this the best way to do it or are there any reasons I should organize my data a better way? Thanks so much in advance for your help!

• Constant Expected "{" before ")" token

• Setting Grouping in UITableView under UINavigationController

  - by climbon

  In my UINavigationController app, my first view is a UITableView. I can't seem to find a way to set the property of this UITableView to 'grouped'. Since UITableView is dynamically generated I don't have the luxury of Interface Builder. Searched forums here and googled other places and closest I saw was to override either initWithStyle or initWithCoder as follows. (id)initWithStyle:(UITableViewStyle)style { if (self = [super initWithStyle:UITableViewStyleGrouped]) { } return self; } However this above function never gets called. when I overrided initWithCoder I could see it worked and I was able to change UITableView contents to grouped. But then title automatically became 'Root View Controller' and none of the cells were active anymore although they got grouped fine. That is while they looked active but if you click on them, those cells won't do anything. But I have seen apps which have their very first view being UITableView is grouped. So there must be a way to do it but I don't know how.

• NSUndoManager won't undo editing of a NSMutableDictionary

  - by xon1c

  Hi, I'm experiencing problems with the undo operation. The following code won't undo an removeObjectForKey: operation but the redo operation setObject:ForKey: works. - (void) insertIntoDictionary:(NSBezierPath *)thePath { [[[window undoManager] prepareWithInvocationTarget:self] removeFromDictionary:thePath]; if(![[window undoManager] isUndoing]) [[window undoManager] setActionName:@"Save Path"]; NSLog(@"Object id is: %d and Key id is: %d", [currentPath objectAtIndex:0], thePath); [colorsForPaths setObject:[currentPath objectAtIndex:0] forKey:thePath]; } - (void) removeFromDictionary:(NSBezierPath *)thePath { [[[window undoManager] prepareWithInvocationTarget:self] insertIntoDictionary:thePath]; if(![[window undoManager] isUndoing]) [[window undoManager] setActionName:@"Delete Path"]; NSLog(@"Object id is: %d and Key id is: %d", [[colorsForPaths allKeys] objectAtIndex:0], thePath); [colorsForPaths removeObjectForKey:thePath]; } The output on the console looks like: // Before setObject:ForKey: Object id is: 1184384 and Key id is: 1530016 // Before removeObjectForKey: UNDO Object id is: 2413664 and Key id is: 1530016 I don't get why the Object id is different although the Key id remains the same. Is there some special undo/redo handling of NSMutableDictionary objects? thx xonic

• checking player prefs from unity in xcode

  - by user313100

  I made a simple scene that has some GUI buttons in Unity. When you press a button it will set a player preference to 1. I have a button for facebook, twitter and a store. In XCode, when the value hits 1, it switches to a new window with facebook, twitter or the store. My problem is that when I try and retrieve the player preferences in XCode, they always come up as null. To compound my confusion, my code seems to respond to the switch to 1 and it switches to the new window when the value hits 1. Any ideas why it manages to switch to the other window and why I am getting null values? - (void) applicationDidFinishLaunching:(UIApplication*)application { printf_console("-> applicationDidFinishLaunching()\n"); NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults]; [userDefaults setInteger:0 forKey:@"Store"]; [userDefaults setInteger:0 forKey:@"Facebook"]; [userDefaults setInteger:0 forKey:@"Twitter"]; _storeWindow = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; _facebookWindow = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; _twitterWindow = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; viewControllerSK = [[SKViewController alloc]initWithNibName:@"SKViewController" bundle:nil]; viewControllerFacebook = [[xutils_exampleViewController alloc]initWithNibName:@"FacebookViewController" bundle:nil]; viewControllerTwitter = [[xutils_exampleViewController2 alloc]initWithNibName:@"TwitterViewController" bundle:nil]; [_storeWindow addSubview:viewControllerSK.view]; [_facebookWindow addSubview:viewControllerFacebook.view]; [_twitterWindow addSubview:viewControllerTwitter.view]; [SKStoreManager sharedManager]; [self startUnity:application]; } - (void) applicationDidBecomeActive:(UIApplication*)application { printf_console("-> applicationDidBecomeActive()\n"); if (gDidResignActive == true) { UnitySetAudioSessionActive(true); UnityPause(false); } gDidResignActive = false; [self newTimer]; } - (void) applicationWillResignActive:(UIApplication*)application { printf_console("-> applicationDidResignActive()\n"); UnitySetAudioSessionActive(false); UnityPause(true); gDidResignActive = true; } - (void) applicationDidReceiveMemoryWarning:(UIApplication*)application { printf_console("WARNING -> applicationDidReceiveMemoryWarning()\n"); } - (void) applicationWillTerminate:(UIApplication*)application { printf_console("-> applicationWillTerminate()\n"); UnityCleanup(); } -(void)newTimer { NSTimer *theTimer = [self getTimer]; [theTimer retain]; [[NSRunLoop currentRunLoop] addTimer: theTimer forMode: NSDefaultRunLoopMode]; } -(NSTimer *)getTimer { NSTimer *theTimer; theTimer = [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector: @selector(onLoop) userInfo:nil repeats:YES]; return [theTimer autorelease]; } -(void)onLoop { NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults]; //NSLog(@"FB: %@", [userDefaults integerForKey:@"Facebook"]); if ([userDefaults integerForKey:@"Store"] != 1 && [userDefaults integerForKey:@"Facebook"] != 1 && [userDefaults integerForKey:@"Twitter"] != 1) { UnityPause(FALSE); _window.hidden = NO; _storeWindow.hidden = YES; _facebookWindow.hidden = YES; _twitterWindow.hidden = YES; [_window makeKeyWindow]; } if ([userDefaults integerForKey:@"Store"] == 1) { UnityPause(TRUE); _storeWindow.hidden = NO; _window.hidden = YES; [_storeWindow makeKeyWindow]; } if ([userDefaults integerForKey:@"Facebook"] == 1) { UnityPause(TRUE); _facebookWindow.hidden = NO; _window.hidden = YES; [_facebookWindow makeKeyWindow]; } if ([userDefaults integerForKey:@"Twitter"] == 1) { UnityPause(TRUE); _twitterWindow.hidden = NO; _window.hidden = YES; [_twitterWindow makeKeyWindow]; } } -(void) dealloc { DestroySurface(&_surface); [_context release]; _context = nil; [_window release]; [_storeWindow release]; [_facebookWindow release]; [_twitterWindow release]; [viewControllerSK release]; [viewControllerFacebook release]; [viewControllerTwitter release]; [super dealloc]; }

• Changing the title of a MFMailComposeViewController

  - by Badescu Alexandru

  Although i know changing MFMailComposeViewController is fround upon, i'm taking a risk. I found some ideas such as [self presentModalViewController:controller animated:YES]; // Existing line [[[[controller viewControllers] lastObject] navigationItem] setTitle:@"SomethingElse"]; and [[[[(MFMailComposeViewController*)vc navigationBar] items] objectAtIndex:0] setTitle:@" SomethingElse"]; but the odd thing is that the title is "SomethingElse" for like 2 seconds and after that it returns to the subject that is set. I've tried other solutions as well but the same output. I am using SHK (ShareKit) to connect to social. Here is the code from showViewController : if ([vc respondsToSelector:@selector(modalPresentationStyle)]) vc.modalPresentationStyle = [SHK modalPresentationStyle]; if ([vc respondsToSelector:@selector(modalTransitionStyle)]) vc.modalTransitionStyle = [SHK modalTransitionStyle]; [topViewController presentModalViewController:vc animated:YES]; [[[[(MFMailComposeViewController*)vc navigationBar] items] objectAtIndex:0] setTitle:@" "]; [(UINavigationController *)vc navigationBar].barStyle = [(UINavigationController *)vc toolbar].barStyle = [SHK barStyle]; self.currentView = vc;

• EXC_BAD_ACCESS when trying to release an ABRecordRef

  - by synic

  I've got the following class that is a wrapper around an ABPerson (ABRecordRef): @interface Recipient : NSObject { ABRecordRef person; } - (id)initWithPerson:(ABRecordRef)person; @end @implementation - (id)initWithPerson:(ABRecordRef)_person { if(self = [super init]) person = CFRetain(_person); return self; } - (void)dealloc { if(person) CFRelease(person); [super dealloc]; } @end I've left some of the methods out, but they aren't relevant to this question. Everything works fine, except I get an EXC_BAD_ACCESS on the if(person) CFRelease(person); line. Why does this happen? I'm not calling CFRelease or CFRetain at all anywhere else in my app.

• Concatenate String to Evernote Markup Language (ENML) in python

  - by Adam the Mediocre

  I am looking to add a string containing the user's text input to the note.content of my note. After reading, I have found how to add resources, but I don't want the resource to be an attachment, I want it to be the actual text. Here is some of the code: title= self.textEditTitle.text() body= self.textEditBody.text() auth_token = "secret stuff!" client = EvernoteClient(token=auth_token, sandbox=True) note_store = client.get_note_store() nBody = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>" nBody += "<!DOCTYPE en-note SYSTEM \"http://xml.evernote.com/pub/enml2.dtd\">" nBody += "<en-note>%s</en-note>" % body note = Types.Note() note.title = title note.content= nBody Any advice would be great, as I'm just starting out with this api and it looks like it's full of potential once I figure it out!

• Rails migrations: Undo default setting for a column

  - by wulfovitch

  Hi Stack Overflow Community! I have the problem, that I have an migration in Rails that sets up a default setting for a column, like this example: def self.up add_column :column_name, :bought_at, :datetime, :default => Time.now end Suppose, I like to drop that default settings in a later migration, how do I do that with using rails migrations? My current workaround is the execution of a custom sql command in the rails migration, like this: def self.up execute 'alter table column_name alter bought_at drop default' end But I don't like this approach, because I am now dependent on how the underlying database is interpreting this command. In case of a change of the database this query perhaps might not work anymore and the migration would be broken. So, is there a way to express the undo of a default setting for a column in rails? Thanks in advance!

• Why doesn't this UIButton show its text label?
