Question

在我的项目中，我有不同的故事板文件来支持不同的iPhone大小，这里是处理在AppDelegate中选择正确的故事板文件的代码：

#define kMain5Name @"Main5"
#define kMain4sName @"Main4s"
#define kMain6Name @"Main6"
#define kMain6plusName @"Main6plus"

if (window.frame.size.height == 568){
    UIStoryboard *storyBoard = [UIStoryboard storyboardWithName:kMain5Name bundle:[NSBundle mainBundle]];
    id rootViewController = [storyBoard instantiateInitialViewController];
    [window setRootViewController:rootViewController];
} else if (window.frame.size.height == 480){
    UIStoryboard *storyBoard = [UIStoryboard storyboardWithName:kMain4sName bundle:[NSBundle mainBundle]];
    id rootViewController = [storyBoard instantiateInitialViewController];
    [window setRootViewController:rootViewController];
} else if (window.frame.size.height == 667){
    UIStoryboard *storyBoard = [UIStoryboard storyboardWithName:kMain6Name bundle:[NSBundle mainBundle]];
    id rootViewController = [storyBoard instantiateInitialViewController];
    [window setRootViewController:rootViewController];
} else if (window.frame.size.height == 736){
    UIStoryboard *storyBoard = [UIStoryboard storyboardWithName:kMain6plusName bundle:[NSBundle mainBundle]];
    id rootViewController = [storyBoard instantiateInitialViewController];
    [window setRootViewController:rootViewController];
}

我也有背景音乐。当我运行应用程序时，它会显示一个黑屏，即使在物理设备上也可播放音乐。我尝试重置模拟器内容和设置，清理项目和评论上面的代码，我也有主界面设置在mt项目导航器中的LaunchImage（.xib），但无济于事.. 难道我做错了什么？还有另一种支持不同iPhone尺寸的方法吗？
