  • UITableView background customization strange behavior

    - by Omer
    Hi, There is a couple of hours that I'm trying to set a tableView background image. My controller is a subclass of UITableViewController, and I simply wrote this lines of code in ViewDidLoad method. UIImage *image = [UIImage imageNamed:@"home-portrait-iphone.png"]; UIImageView *imageView = [[UIImageView alloc] initWithImage:image]; self.tableView.backgroundView = imageView; Everything looks great on the simulator, I mean, I see my table and as background view, y can see the image. But when the app is running on the device (ipod touch), I get this error: Program received signal: “SIGABRT”. and the stack says: * -[UITableView setBackgroundView:]: unrecognized selector sent to instance 0x812e00 Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '** -[UITableView setBackgroundView:]: unrecognized selector sent to instance 0x812e00' and the exception is thrown in the assignment, a mean this line: self.tableView.backgroundView = imageView; any ideas? Thank you in advance.

    - by Alerty
    What are the consequences (positive/negative) of using the unsafe keyword in C# to use pointers? For example, what becomes of garbage collection, what are the performance gains/losses, what are the performance gains/losses compared to other languages manual memory management, what are the dangers, in which situation is it really justifiable to make use of this language feature... ?

  • pushViewController using UINavigationItem instead of UINavigationController

    - by jaume
    Hello, I have implemented a method didSelectRowAtIndexPath that should push another view. I have a code running properly using a navigationController but in this case I am using a navigationItem on a view. How could I trigger a view?

  • Why is UIApplicationWillChangeStatusBarFrameNotification not sent when the in-call status bar is sho

    - by Sbrocket
    I've been trying to listen for changes in the status bar height – such as when the in-call status bar is shown or hidden – by listening for the UIApplicationWillChangeStatusBarFrameNotification notification to be sent. Fairly straightforward code here... [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(statusBarWillChangeFrame:) name:UIApplicationWillChangeStatusBarFrameNotification object:nil]; But the notification never seems to be sent in that case, either on the Simulator by using the "Toggle In-Call Status Bar" option or on the device when a call ends with the application open. In addition, the similar UIApplicationDelegate method is not called. According to the documentation, UIApplicationWillChangeStatusBarFrameNotification Posted when the application is about to change the frame of the status bar. The userInfo dictionary contains an NSValue object that encapsulates a CGRect structure expressing the location and size of the new status bar frame. Use UIApplicationStatusBarFrameUserInfoKey to access this value. Can anyone explain why this notification is not being sent in response to the in-call status bar being shown or hidden? According to the documentation, it should be.

  • progressIndicator does not update till about 10 seconds after awakeFromNib occures

    - by theprojectabot
    I have been trying to get this one section of my UI to immediatly up date when the document loads into view. The awakeFromNib fires the pasted code and then starts a timer to repeat every 10 seconds... I load a default storage location: ~/Movies... which shows up immediately.. yet the network location that is saved in the document that gets pulled from the XML only seems to show up after the second firing of the - (void)updateDiskSpaceDisplay timer. I have set breakpoints and know that the ivars that contain the values that are being put into the *fileSystemAttributes is the network location right when the awakeFromNib occurs... Im confused why it magically appears after the second time firing instead of immediately displaying the write values. - (void)updateDiskSpaceDisplay { // Obtain information about the file system used on the selected storage path. NSError *error = NULL; NSDictionary *fileSystemAttributes = [[NSFileManager defaultManager] attributesOfFileSystemForPath:[[[self settings] containerSettings] storagePath] error:&error]; if( !fileSystemAttributes ) return; // Get the byte capacity of the drive. long long byteCapacity = [[fileSystemAttributes objectForKey:NSFileSystemSize] unsignedLongLongValue]; // Get the number of free bytes. long long freeBytes = [[fileSystemAttributes objectForKey:NSFileSystemFreeSize] unsignedLongLongValue]; // Update the level indicator, and the text fields to show the current information. [totalDiskSpaceField setStringValue:[self formattedStringFromByteCount:byteCapacity]]; [totalDiskSpaceField setNeedsDisplay:YES]; [usedDiskSpaceField setStringValue:[self formattedStringFromByteCount:(byteCapacity - freeBytes)]]; [usedDiskSpaceField setNeedsDisplay:YES]; [diskSpaceIndicator setMaxValue:100]; [diskSpaceIndicator setIntValue:(((float) (byteCapacity - freeBytes) / (float) byteCapacity) * 100.0)]; [diskSpaceIndicator display:YES]; } thoughts? my awakeFromNib: - (void)awakeFromNib { [documentWindow setAcceptsMouseMovedEvents:YES]; [documentWindow setDelegate:self]; [self updateSettingsDisplay]; [self updateDiskSpaceDisplay]; [self setDiskSpaceUpdateTimer:[NSTimer scheduledTimerWithTimeInterval:10.0 target:self selector:@selector(updateDiskSpaceDisplay) userInfo:NULL repeats:YES]]; [self setUpClipInfoTabButtons]; [self performSelector:@selector(setupEngineController) withObject:NULL afterDelay:0.1]; }

  • When we should use pushScene and replaceScene in cocos2d ?

    - by srikanth rongali
    Hi, I cocos2d, I am using pushScene and replaceScene to move to next scene. But, I am confused which we should use? When I am using replaceScene in some places app is crashing and giving errors like -[UITextView length]: unrecognized selector sent to instance 0x842a750 Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[UITextView length]: unrecognized selector sent to instance 0x842a750' But, in my program I am not passing length to UITextView. My program is in this way In scene1 I have UITextView, and I am replacing this scene with scene2. Then -(id)buttonPressed:(id)sender { [description removeFromSuperview]; // It is the textView(description) CCScene *Scene = [CCScene node]; CCLayer *Layer = [scene2 node]; [Scene addChild:Layer]; [[CCDirector sharedDirector] setAnimationInterval:1.0/60]; [[CCDirector sharedDirector] replaceScene: Scene]; } But, when I am using pushScene in presence of replaceScene it is working good. Please clarify me which one should use in which cases ? Thank You

  • Weak linking on iPhone refuses to work

    - by Jonathan Grynspan
    I've got an iPhone app that's mainly targetting 3.0, but which takes advantage of newer APIs when they're available. Code goes something like this: if (UIApplicationDidEnterBackgroundNotification != NULL) [nc addObserver: self selector: @selector(irrelelvantCallbackName:) name: UIApplicationDidEnterBackgroundNotification object: nil]; Now, according to everything Apple's ever said, if the relevant APIs are weakly linked, that will work fine because the dynamic linker will evaluate UIApplicationDidEnterBackgroundNotification to NULL. Except that it doesn't. The application compiles, but as soon as it hits "if (UIApplicationDidEnterBackgroundNotification != NULL)" it crashes with EXC_BAD_ACCESS. Is this simply a matter of a compiler flag I need to set? Or am I going about this the wrong way?

    I am writing some Selenium tests and I need to be able to find an ancestor of a WebElement that I have already found. This is what I'm trying but is returning no results // checkbox is also a WebElement WebElement container = checkbox.findElement(By.xpath( "current()/ancestor-or-self::div[contains(@class, 'x-grid-view')]") ); The image below shows the div that I have selected highlighted in dark blue and the one I want to find with an arrow pointing at it.

  • UIMenuController Custom Items

    - by Joshua
    I have created a UIMenuController and have set it a custom menu item like so: UIMenuController *menuController = [UIMenuController sharedMenuController]; UIMenuItem *item1 = [[UIMenuItem alloc] initWithTitle:@"Do This" action:@selector(item1)]; [menuController setMenuItems:[NSArray arrayWithObject:item1]]; But I wanted that object to be the only one to appear so I added this code: - (BOOL)canPerformAction: (SEL)action withSender: (id)sender { BOOL answer = NO; if (action == @selector(item1)) answer = YES; return answer; } The problem is it still shows other## Heading ## items, such as "Select", "Select All" and "Paste". This may have something to do with this being displayed in a UITextView. But how do I stop if from displaying all other items?

  • Testing MPMoviePlayerViewController in iPad simulator

    - by hgpc
    I have a view that shows a MPMoviePlayerViewController modally. When testing it in the iPad simulator it works well on the first try. If I dismiss the video and then show the view again, the player only plays the audio, but not the video. Is this a simulator quirk or am I doing something wrong? Here's my code: - (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; MPMoviePlayerViewController* v = [[MPMoviePlayerViewController alloc] initWithContentURL:url]; [[NSNotificationCenter defaultCenter] addObserver:self selector: @selector(playbackDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:v.moviePlayer]; [self presentMoviePlayerViewControllerAnimated:v]; [v release]; } -(void) playbackDidFinish:(NSNotification*)aNotification { MPMoviePlayerController *player = [aNotification object]; [[NSNotificationCenter defaultCenter] removeObserver:self name:MPMoviePlayerPlaybackDidFinishNotification object:player]; [player stop]; [self dismissMoviePlayerViewControllerAnimated]; }

  • Showing popup in the new FB JS SDK

  • Detecting rotation to landscape manually

    - by Thomas Joos
    hi all, I am working on an iPhone application based on UITabBarController and UIViewControllers for each page. The app needs to run in portrait mode only, so every view controller + app delegate goes with this line of code: (BOOL)shouldAutorotateToInterfaceOrientation: (UIInterfaceOrientation)interfaceOrientation { return (interfaceOrientation == UIInterfaceOrientationPortrait); } There is one view controller where I would like to pop up a UIImageView when the iPhone is rotaed to landscapeleft. The design of the image looks landscape, although the width and height are 320x460 ( so its portrait ). How can/should I detect this type of rotation manually, just in this specific view controller, withouth having an auto rotation on the entire view? Thomas UPDATE: Thanks! I added this listener in the viewDidLoad: [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(didRotate:)name:UIDeviceOrientationDidChangeNotification object:nil]; the didRotate looks like this: (void) didRotate:(NSNotification *)notification { UIDeviceOrientation orientation = [[UIDevice currentDevice] orientation]; if (orientation == UIDeviceOrientationLandscapeLeft) { //your code here } }

  • Is there an NSCFTimer memory leak?

    - by mystify
    I tracked down a memory leak with instruments. I always end up with the information that the responsible library is Foundation. When I track that down in my code, I end up here, but there's nothing wrong with my memory management: - (void)setupTimer { // stop timer if still there [self stopAnimationTimer]; NSTimer *timer = [NSTimer scheduledTimerWithTimeInterval:0.2 target:self selector:@selector(step:) userInfo:nil repeats:YES]; self.animationTimer = timer; // retain property, -release in -dealloc method } the property animationTimer is retaining the timer. In -dealloc I -release it. Now that looks like a framework bug? I checked with iPhone OS 3.0 and 3.1, both have that problem every time I use NSTimer like this. Any idea what else could be the problem? (my memory leak scan interval was 0.1 seconds. but same thing with 5 seconds)

  • CSS selectors : should I make my CSS easier to read or optimise the speed

    - by Laurent Bourgault-Roy
    As I was working on a small website, I decided to use the PageSpeed extension to check if their was some improvement I could do to make the site load faster. However I was quite surprise when it told me that my use of CSS selector was "inefficient". I was always told that you should keep the usage of the class attribute in the HTML to a minimum, but if I understand correctly what PageSpeed tell me, it's much more efficient for the browser to match directly against a class name. It make sense to me, but it also mean that I need to put more CSS classes in my HTML. It make my .css file harder to read. I usually tend to mark my CSS like this : #mainContent p.productDescription em.priceTag { ... } Which make it easy to read : I know this will affect the main content and that it affect something in a paragraph tag (so I wont start to put all sort of layout code in it) that describe a product and its something that need emphasis. However it seem I should rewrite it as .priceTag { ... } Which remove all context information about the style. And if I want to use differently formatted price tag (for example, one in a list on the sidebar and one in a paragraph), I need to use something like that .paragraphPriceTag { ... } .listPriceTag { ... } Which really annoy me since I seem to duplicate the semantic of the HTML in my classes. And that mean I can't put common style in an unqualified .priceTag { ... } and thus I need to replicate the style in both CSS rule, making it harder to make change. (Altough for that I could use multiple class selector, but IE6 dont support them) I believe making code harder to read for the sake of speed has never been really considered a very good practice . Except where it is critical, of course. This is why people use PHP/Ruby/C# etc. instead of C/assembly to code their site. It's easier to write and debug. So I was wondering if I should stick with few CSS classes and complex selector or if I should go the optimisation route and remove my fancy CSS selectors for the sake of speed? Does PageSpeed make over the top recommandation? On most modern computer, will it even make a difference?

  • JQuery - Ajax saving sortables in connected lists when sortable item is moved

    - by Ben Sinclair
    I have multiple JQuery sortable lists that connect with each other... They allow you to assign users to certain roles. Basically what I want to do is when a user is dragged from one list to another, I want JQuery to pick up the first list that the user was moved from so that I can send an AJAX request to delete it from that list in my database. I tried the following but every time you move the user over a list and haven't even dropped it within a list, it sends this request which means I'll be sending multiple AJAX requests... Does that make sense? $( ".selector" ).sortable({ out: function(event, ui) { ... } }); From my testing, I can use the following code to just update the list that user has been moved to so I've got the second half covered: $( ".selector" ).sortable({ receive: function(event, ui) { ... } }); Hopefully I am making sense :)
