- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 方法中写入 sleep(5.0)

Write sleep(5.0) in your

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions method.

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    

  /*this will pause main thread for x interval seconds. 
  put on the top of application:didFinishLaunchingWithOptions, so it will not 
  proceed to show window until sleep interval is finished.*/

    [NSThread sleepForTimeInterval:5]; //add 5 seconds longer.
   //other code....
}

您需要创建一个视图控制器来显示启动屏幕,如下所示。

   - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
    {
        [self generateRandomSplashScreen];

        [self performSelector:@selector(removeSplashScreen) withObject:nil afterDelay:SPLASHSCREEN_DELAY];

    [self otherViewControllerLoad]; // the other view controller

        [self.window makeKeyAndVisible];
        return YES;
    }
    -(void) generateRandomSplashScreen
    {
        splashScreenViewController = [[SplashScreenController alloc] initWithNibName:@"SplashScreenController" bundle:[NSBundle mainBundle]];

        [self.window addSubview:self.splashScreenViewController.view];
    }

    -(void) removeSplashScreen
    {
        [splashScreenViewController.view removeFromSuperview];
        self.window.rootViewController = self.tabBarController;
        [splashScreenViewController release];
    }

You need to create a view controller for displaying the splash screen as done below.

   - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
    {
        [self generateRandomSplashScreen];

        [self performSelector:@selector(removeSplashScreen) withObject:nil afterDelay:SPLASHSCREEN_DELAY];

    [self otherViewControllerLoad]; // the other view controller

        [self.window makeKeyAndVisible];
        return YES;
    }
    -(void) generateRandomSplashScreen
    {
        splashScreenViewController = [[SplashScreenController alloc] initWithNibName:@"SplashScreenController" bundle:[NSBundle mainBundle]];

        [self.window addSubview:self.splashScreenViewController.view];
    }

    -(void) removeSplashScreen
    {
        [splashScreenViewController.view removeFromSuperview];
        self.window.rootViewController = self.tabBarController;
        [splashScreenViewController release];
    }

您所说的启动画面可能是“default.png”文件。正如 JustSid 提到的,该文件并不是要用作启动屏幕,而是用作第一个屏幕快照,以改善有关应用程序加载时间的用户体验。检查人机界面指南

如果你想实现闪屏,你应该使用 ie。 NSTimer 和 UIView 组件。

Probably the splash screen you are talking about is "default.png" file. As JustSid mentioned, this file is not intended to be splash screen, rather to be used as a first screen snapshot to improve user experience concerning application loading time. Check human interface guideline
