iOS UILaunchImageFile：一些4英寸屏幕用户看到黑色边框

我的一些用户在他们的4英寸设备上运行我的应用程序时，似乎总是看到一个裁剪过的屏幕。这可能仅限于iPodtouch5G用户，而且似乎发生在iOS6和iOS7上（我仍在调查）。我有一个简单而正确的UILaunchImageFile配置，它可以在我的iPhone 5和所有模拟器上正常工作。有什么想法吗

Info.plist：

...
<key>UILaunchImageFile~ipad</key>
<string>UILaunchImage-iPad</string>
<key>UILaunchImageFile~iphone</key>
<string>UILaunchImage</string>
...

[编辑：我的启动代码，在MyAppDelegate中]

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    ...

    // screen.bounds is the whole display size;
    // screen.applicationFrame is smaller when you show the status bar
    UIScreen * screen = [UIScreen mainScreen];
    CGRect screenBounds = screen.bounds;
    CGRect applicationFrame = screen.applicationFrame;
    self.window = [[[UIWindow alloc] initWithFrame:screenBounds] autorelease];

    // load main ui
    MyUIViewController * main = [[[MyUIViewController alloc] initWithNibName:@"MyUIViewController" bundle:nil] autorelease];
    UIView * rootView = [[[UIView alloc] initWithFrame:screenBounds] autorelease];
    main.view = rootView;
    [main loadIfNeeded];

    self.viewController = main;
    self.window.rootViewController = self.viewController;
    [self.window makeKeyAndVisible];

    ...
}

将所有viewcontrollers模拟器指标设置为4英寸屏幕，我希望这能起作用…我认为您必须调整窗口大小。。。您可以按照链接调整窗口大小：-@Bhrigesh，该链接用于编程MacOS X，而不是iOS。@Bhrigesh，我不使用模拟度量，而是自己设置视图的框架。我通过传入[[UIScreen mainScreen]边界]在代码中创建自己的窗口——代码现在包括在内。

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    ...

    // screen.bounds is the whole display size;
    // screen.applicationFrame is smaller when you show the status bar
    UIScreen * screen = [UIScreen mainScreen];
    CGRect screenBounds = screen.bounds;
    CGRect applicationFrame = screen.applicationFrame;
    self.window = [[[UIWindow alloc] initWithFrame:screenBounds] autorelease];

    // load main ui
    MyUIViewController * main = [[[MyUIViewController alloc] initWithNibName:@"MyUIViewController" bundle:nil] autorelease];
    UIView * rootView = [[[UIView alloc] initWithFrame:screenBounds] autorelease];
    main.view = rootView;
    [main loadIfNeeded];

    self.viewController = main;
    self.window.rootViewController = self.viewController;
    [self.window makeKeyAndVisible];

    ...
}
