iphone - 应用程序在ipod上显示黑屏

Question

该应用程序具有通用性，并且在除iPod之外的所有其他设备上均可正常运行。我用了两个分镜脚本。

这是我在AppDelegate中编写的代码。

 -(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
 {    
    UIImage* background = [UIImage imageNamed:@"navigation-bar-background"];
    [[UINavigationBar appearance] setBackgroundImage:background forBarMetrics:UIBarMetricsDefault];

    [[UIBarButtonItem appearance] setBackButtonBackgroundImage:[[UIImage imageNamed:@"black-back-button"]resizableImageWithCapInsets:UIEdgeInsetsMake(0, 10, 0, 10)] forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
    [[UIBarButtonItem appearance] setBackButtonBackgroundImage:[[UIImage imageNamed:@"black-back-button-landscape"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 10, 0, 10)] forState:UIControlStateNormal barMetrics:UIBarMetricsLandscapePhone];

    [[UISlider appearance] setThumbImage:[UIImage imageNamed:@"knob-button"] forState:UIControlStateNormal];
    return YES;
}

Answer 1

只需更改图像(确保新的试用图像为png格式)，然后查看它是否显示。
