Question

我必须针对iPhone 5屏幕尺寸优化我的旧项目之一。 RootViewController没有XIB。我在应用程序didFinishLaunchingWithOptions：方法中尝试了一些技巧。但没有任何效果。

这是应用程序的代码didFinishLaunchingWithOptions：方法。 **注意：注释行是我试过的技巧

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[self createEditableCopyOfFileIfNeeded:@"ChapterInfo.plist"];



mainWindow = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];

//    [mainWindow  setAutoresizingMask:UIViewAutoresizingFlexibleHeight|UIViewAutoresizingFlexibleWidth];
//    [mainWindow setAutoresizesSubviews:YES];


readerDemoController = [[ReaderDemoController alloc] initWithNibName:nil bundle:nil]; // Demo controller

//    [readerDemoController.view setAutoresizingMask:UIViewAutoresizingFlexibleHeight|UIViewAutoresizingFlexibleWidth];
//    [readerDemoController.view setAutoresizesSubviews:YES];

navigationController = [[UINavigationController alloc] initWithRootViewController:readerDemoController];

UIImage *imgeBack = [UIImage imageNamed:@"back.png"];
mainWindow.backgroundColor = [UIColor colorWithPatternImage:imgeBack]; // Window background color

navigationController.navigationBar.barStyle = UIBarStyleBlackOpaque; 
[navigationController.navigationBar setBackgroundImage:[UIImage imageNamed:@"titlebar.png"] forBarMetrics:UIBarMetricsDefault];
navigationController.navigationBar.translucent = YES;

//    [navigationController.view setAutoresizingMask:UIViewAutoresizingFlexibleHeight|UIViewAutoresizingFlexibleWidth];
//    [navigationController.view setAutoresizesSubviews:YES];

mainWindow.rootViewController = navigationController; // Set the root view controller

[mainWindow makeKeyAndVisible];


return YES;
}

如果不从一开始就完成项目，我如何克服这个问题？请给我一些帮助。

据我所知，你处于信箱模式，你总是有2条黑色条纹（一个在顶部，另一个在底部，在纵向模式下），如果是这样 - A-Live是正确的，只需添加正确的闪屏1136x640 72dpi png，名为Default-568h@2x.png，或者只是在关于丢失图像的警告中进行自动修复。
