问题 I am trying to add a UILabel in UIWindow of AppDelegate from a UIViewController. This is how I am doing this: AppDelegate code : - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease]; // Override point for customization after application launch. if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) { self.viewController

iOS: Programmatically creating UIWindow results in wrong position

问题 In iOS 5.1.1, I have found that if I create my UIWindow (I'm tired of IB), and set its frame to [UIScreen mainScreen].bounds, the window shows up under the status bar . However if I do the same thing is iOS 6, it appears in the right spot just below the status bar. CGRect r = [[UIScreen mainScreen] bounds]; self.window = [[UIWindow alloc] initWithFrame: r]; self.detailViewController = [[DetailViewController alloc] init]; self.window.rootViewController = self.detailViewController; [self.window

How does one eliminate the rounded corners on the main window on an iPad app?

由 一笑奈何 提交于 2019-12-07 02:05:35
问题 I have seen some iPad apps that fill the screen (e.g. Stanza) or have squared off corners under the status bar (e.g. the iPod player has square corners at the top; can't tell at the bottom). Anyone know how this is done? It seems that, by default, the top-level UIWindow has a clipping region applied, as any subviews I place in that window get clipped off in those corners. If that is the case, is there a way to get rid of this? BTW, the clipping only seems to be there on the iPad, not on my

Get Application's main window

问题 UIApplication has a method keyWindow , however if an alert view is showing then this returns the window of the alert view and not the main window of the application. How can I get the app's main window? 回答1: The UIApplicationDelegate usually has a reference to the "main window": [[[UIApplication sharedApplication] delegate] window]; Furthermore, UIApplication has an array of windows [[UIApplication sharedApplication] windows] . See the UIApplication Class Reference. 回答2: I'm not 100% sure

Setting UIScreen's mode / resolution

问题 I have to set the external UIScreen's mode to run with the resolution 1024x768. First I search if the screen supports this resolution: if ([[UIScreen screens] count] > 1){ CGSize size1024; size1024.height = 0; size1024.width = 0; UIScreenMode *screenMode1024 = nil; UIScreen *secondScreen = [[UIScreen screens] objectAtIndex:1]; for(int i = 0; i < [[secondScreen availableModes] count]; i++) { UIScreenMode *current = [[[[UIScreen screens] objectAtIndex:1] availableModes] objectAtIndex: i]; if

trouble with displaying another UIWindow

问题 I'm writing an iPad app, and I'm trying to display a second UIWindow on top of the main window in my app. The main thing I'm trying to do is create a log in window (how to present a login, with UISplitViewController?), and it seems that creating a second window here might be a good option. I've made a very simple app to try this out. When the user hits a button, then I'm trying to show the second window. Here's the code: - (IBAction)showOtherWindow:(id)sender { UIWindow* otherWindow = [

问题 I'm looking for the proper way to snapshot the entire iPhone screen including the keyboard. i found some code to snapshot the screen: CGRect screenCaptureRect = [UIScreen mainScreen].bounds; UIView *viewWhereYouWantToScreenCapture = [[UIApplication sharedApplication] keyWindow]; //screen capture code UIGraphicsBeginImageContextWithOptions(screenCaptureRect.size, NO, [UIScreen mainScreen].scale); [viewWhereYouWantToScreenCapture drawViewHierarchyInRect:screenCaptureRect afterScreenUpdates:NO];

“Normal” UIButton causing obj_stack_overflow or EXC_BAD_ACCESS exception

问题 It sure looks innocuous enough. In my App Delegate, I check NSUserDefaults for a flag to show tips at startup. If it’s set then, at the end of applicationDidFinishLaunching: , I do this: TipsViewController *vc = [[TipsViewController alloc] initWithNibName:@“TipsView" bundle:nil]; [window addSubview:vc.view]; [vc release]; The idea is to show this view temporarily. (Note that it’s not a modal VC. No Navigation Controller at this point, plus there’s no navigation bar in this view anyway.) Once

UIWindow frame in ios 8 different from ios 7 in Landscape

I've create simple module where I add subview to UIWindow. In simulator ios 7(Xcode 5.1.1) I have printed self.windows and I get: <UIWindow: 0x8db1670; frame = (0 0; 768 1024); autoresize = W+H; gestureRecognizers = <NSArray: 0x8db1a70>; layer = <UIWindowLayer: 0x8db17d0>> but on ios8 (Xcode 6 beta 6) I get: <UIWindow: 0x794320d0; frame = (0 0; 1024 768); gestureRecognizers = <NSArray: 0x79437a80>; layer = <UIWindowLayer: 0x7943c400>> The question is: why there is a difference in frame property? fdiaz Probably in your AppDelegate you initializing your UIWindow like this self.window = [
