没有NIB，UIWindow不填充屏幕，iOS 7 [英] No NIBs, UIWindow Not Filling Screen, iOS 7

问题描述

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。

I'm avoiding using NIBs completely. I'm getting problems on iOS 7.1, but not on iOS 8.x.

iOS 7与iOS 8

代码在 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;
}

我也试过一些处理iOS 8的方法，但即使设置了 UIWindow frame 到 5000,5000 会产生相同的结果。

I've also tried some methods dealing with iOS 8, but even settings the UIWindow frame to 5000, 5000 produces the same results.

[我已经看过一些相关的问题，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]

[I've seen a number of related questions and tried out the suggestions, but to no avail, including flipping the bounds if it's iOS 8, etc. etc.]

推荐答案

问题是你没有4英寸屏幕的启动图像，所以iPhone 5s正在治疗这个应用程序作为一个3.5英寸的应用程序（iPhone 4）和letterboxing它。

The problem is that you don't have a launch image for the 4-inch screen, so the iPhone 5s is treating this app as a 3.5-inch app (iPhone 4) and letterboxing it.
