  • xCode complitions, spelling checkings stoped

    - by SentineL
    My xCode 4.3.2 stopped to show up spelling errors and completions for code. The only way to find out if there is any error in the code - build it. xCode colores only keywords such as if, else, for etc. All other code hasn't colored. Shown only a few very strange completions. For example: CGPoint p; p.y // complition is "YES" p.x // complition is "xor" Completions for methods calls are only nearaly used methods. How can I fix this? I rebooted my mac several times allready, and didn't find any staff obout this in xCode's preferences.

  • cocos2d 2.x scene retainCount

    - by Shefy Gur-ary
    I'm pushing a scene to the game I'm working on, after pressing a button in the main menu. This scene is a gameplayScene which should have two layers ad childs: boardLayer and hudLayer. for now I'm testing with the boardLayer, I'm using block to call the gameplayScene to close both itself and the boardLayer, but by the time I get there the retain count of both layer is 3 (seems to be increasing after setting the block to 2, and I'm not sure when it is going up to 3) What cause this, and how should it be handled?

  • how do i get a layer's frame to automatically resize based on its superlayer's frame or its view's f

    - by Kevlar
    I'm experimenting with using cagradientlayer to draw gradients in our app instead of having a subclass of uiview manage gradients. One snafu that i've come across is that when the view that has the gradient as a sublayer of its main layer gets resized to fit the data i am trying to show, the layer doesn't resize along with it. I end up having the gradient layer end at the original frame size while my view's frame is much larger. Is there a way to have the sublayer autoresize to fit its superlayer's frame, or the superlayer's view's frame?

  • Interface Builder layout ViewController with its own nib

    - by Sean Clark Hess
    I would like to be able to decide where a sub view is placed, when that view is controlled by its own view controller. This happens frequently on the iPad when you have a semi-complicated view that doesn't fill the entire screen. So, imagine that I want the sub view controller's nib to decide its own width, components, connections, etc, while the parent nib would decide where that view/nib would be placed. I'd really like to lay it out visually instead of programatically. How can I?

  • My UITabBarController isn't appearing, but its first view is?

    - by E-Madd
    I've done some reorganizing of my project recently and now I'm not seeing my tab bar controller, but its first view controller's view is appearing. Here's a breakdown of everything that happens prior to the problem. App Delegate loads FirstViewController with nib. FirstViewController loads the application data from my server and then presents MainViewController with a modal transition. MainViewController is where the UITabBarController is supposed to be appearing. It's a very simple class. The .h @interface MainViewController : UIViewController <UITabBarControllerDelegate> { IBOutlet UITabBarController *tabBarController; } @property (nonatomic, retain) UITabBarController *tabBarController; @end The .m @implementation MainViewController @synthesize tabBarController; - (void)viewDidLoad { NSLog(@"MainViewController viewDidLoad"); //set tab bar controller delegate to self tabBarController.delegate = self; // home view HomeViewController *home = [[HomeViewController alloc] initWithTab]; // menu view MenuViewController *menu = [[MenuViewController alloc] initWithTab]; // special offers view SpecialOffersViewController *so = [[SpecialOffersViewController alloc] initWithTab]; // events view EventsViewController *events = [[EventsViewController alloc] initWithTab]; // info view InfoViewController *info = [[InfoViewController alloc] initWithTab]; //populate the tab bar controller with view controllers NSArray *controllers = [NSArray arrayWithObjects:home, menu, so, events, info, nil]; tabBarController.viewControllers = controllers; //release view controllers [home release]; [menu release]; [so release]; [events release]; [info release]; [controllers release]; //add tab bar controller to view [self.view addSubview:tabBarController.view]; [super viewDidLoad]; } and here's the bit from FirstViewController that modally presents the MainViewController... MainViewController *controller = [[MainViewController alloc] initWithNibName:@"MainViewController" bundle:nil]; controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [self presentModalViewController:controller animated:YES]; [controller release]; I'm not getting any compiler errors or warnings and the app runs swell... no crashing. It just isn't showing the darned TabBar, and it used to when I was creating it on my AppDelegate. I checked everything in my NIB and my outlets seem to be hooked up ok. I have no idea what's happened. Help!

  • Unable to call storyboard from xib

    - by Shruti Kapoor
    I am new to iOS development. I am trying to connect to a storyboard from xib file. My xib View Controller has a "Login" which if successful should connect to storyboard. I have googled and searched on stackoverflow for a solution and I am using this code that is given everywhere: UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil]; YourViewController * yourView = (YourViewController *)[storyboard instantiateViewControllerWithIdentifier:@"identifier ID"]; I have created an identifier for my storyboard as well. However, I am not being redirected to the storyboard no matter what I try. When the login finishes, I go back to my main View Controller (xib). I should be instead redirected to the storyboard. Here is what my code looks like in a file called ProfileTabView.m: -(void) loginViewDidFinish:(NSNotification*)notification { [[NSNotificationCenter defaultCenter] removeObserver:self]; UIStoryboard* storyboard = [UIStoryboard storyboardWithName:@"Storyboard" bundle:nil]; ProfileTabView * yourView = (ProfileTabView *)[storyboard instantiateViewControllerWithIdentifier:@"myID"]; } I have implemeted this code in the function that gets called once the login is successful. However, the storyboard "Storyboard" never gets called. Am i doing this right? Am I supposed to be writing this code anywhere else? Thanks a lot for any help :)

  • How to intercept touch events globally?

    - by mystify
    I have an view which is sometimes covered by some other views. However, if the user slides the finger across the screen, I want to slide that underlying view across the screen, too. I could start making custom views for all those covering subviews and forward all kinds of touch events, but that's somewhat cumbersome. Maybe there's some kind of notification or another way that a UIView or UIControl subclass can be aware of touch events happening right now, no matter where they are. In short: I need an UIView subclass or UIControl subclass which knows about any touch events happening on the entire screen. Or at least if tht's not possible, knowing about any touch events happening above itself in the same underlying superview. Another description: There are 20 views, all reside inside the same superview. The first view is covered by 19 others. But if the user slides across the screen, that first view must slide too, so it must be aware of touch events. Is there any better solution that making all 19 views forward touch events? (yes, all 19 views respond to touch events in this example)

  • iPad UISPlitViewController Common View

    - by saikamesh
    is it possible to have a common view for both master and detail view controllers. What if I need to add a header image(at top, the very first view) common for both the master and detail view controllers. When the device is in the portrait mode the width of the header image view has to shrink to fit to the detail view controller's view and when the orientation changes to landscape the width of the same header image view has to be expanded that is the width of it has to be 1024. Please tell me whether doing this is possible. or any workaround for this?

  • Will it use more and more memory if I keep drawing on the UIView?

    This is my drawRect: CGContextRef context = UIGraphicsGetCurrentContext(); CGContextSetLineWidth(context, 2.0); CGContextSetStrokeColorWithColor(context, [UIColor redColor].CGColor); CGContextMoveToPoint(context, x1, y1); CGContextAddLineToPoint(context, x2, y2); CGContextStrokePath(context); If I run this code thousand times or more. My UIView will have many lines on that. Will it use more memory than only just one line on it? Er... ...I mean, will the program remember the line I draw or after it draw the lines, it won't have any information in the memory. thz .
