没有NIB,UIWindow不填充屏幕,iOS 7

Question

我完全避免使用NIB.我在iOS 7.1上遇到问题,但在iOS 8.x上没有.

iOS 7与iOS 8

代码看起来像这样 UIResponder <UIApplicationDelegate>

- (void) setupViewController {
    CGRect frame = UIScreen.mainScreen.bounds;
    self.window = [[UIWindow alloc] initWithFrame:frame];
    self.window.backgroundColor = UIColor.whiteColor; // viewController's view is green
    ViewController *viewController = [[ViewController alloc] init];
    UIView *view = [[UIView alloc] initWithFrame:self.window.bounds];
    viewController.view = view;
    self.window.rootViewController = viewController;
    [self.window makeKeyAndVisible];
}

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    [self setupViewController];
    return YES;
}

我也尝试了一些方法处理的iOS 8,但即使设置了UIWindow frame以5000, 5000产生相同的结果.

[我已经看到了一些相关的问题,并尝试了这些建议,但无济于事,包括如果它是iOS 8等,则翻转界限等]

问题是你没有4英寸屏幕的启动图像,所以iPhone 5s将这个应用程序视为一个3.5英寸的应用程序(iPhone 4)和letterboxing它.
