问题 There seems to be a some post related to my problem but none seems to help. How do I adjust the anchor point of a CALayer, when Auto Layout is being used? I have a scaled preview of my app (as a tutorial), which the standard view (and viewcontroller) scaled down and shown on another view. ============= = = = --------- = = - - = = -Preview- = = - - = = --------- = = View = ============= For this I use this code: previewViewController.view.transform = CGAffineTransformMakeScale(scale*2, scale*2

问题 our app got rejected by apple for Design - 4.0 We noticed that the user is taken to Safari to sign in or register for an account when logging in with Google+, which provides a poor user experience.

问题 I am new in autolayout (I am good in autoresizing). My requirement is:- I have 2 view (say blue and green, width and height of both view is 300 pixel in iPhone5). height and width of both view can change according to screen resolution. X and Y origin can also change. What constraints should I use for this autoresizing masks. 回答1: It is unclear if the blue and green are siblings or if one contains the other.

问题 My images are not displaying on iPad AIRs, but are displaying on other iPads. They are not displaying in Image views or on buttons. Besides my images, the Segmented Control image is also not displaying, although I can still tap on the buttons and segmented control where I know they exist on the UI. I found that background images on my buttons do display, but an image on my buttons do not. Maybe this will help - I think this started after I got the message about required 64 bit support as of 2

问题 I have an interesting problem. I have a very basic tableview with a bunch of cells of varying height. It's using the iOS 8 UITableViewAutomaticDimension and auto layout constraints. @interface ViewController () <UITableViewDataSource> @property (weak, nonatomic) IBOutlet UITableView *tableView; @property (strong, nonatomic) NSArray *sentences; @end @implementation ViewController - (void)viewDidLoad { [super viewDidLoad]; self.tableView.estimatedRowHeight = 44; self.tableView.rowHeight =

问题 My app crashes when I launch it in iOS 7.1 but works fine in iOS 8.1 The error I get is this: dyld: Library not loaded: /System/Library/Frameworks/AVKit.framework/AVKit Referenced from: MY APP Reason: no suitable image found.

问题 My app handles URL Schemes. When it is already running and gets called from another app, it behaves correctly and without a problem. However, when it is completely closed (as in not-in-background-mode), and another app calls it, it crashes immediately. I've already set the "Wait for executable to be launched" option so I could debug the application:willFinishLaunchingWithOptions: but it seems that it is not getting called. I've also implemented -application:openURL:sourceApplication
