更改iPhone的初始屏幕时间

我如何让启动屏幕停留更长时间，例如5秒钟？

Answer 1

您需要创build一个视图控制器来显示启animation面，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]; } 

Answer 2

写你的sleep(5.0)

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions方法。

Answer 3

 - (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.... } 

Answer 4

可能您所说的启animation面是“default.png”文件。 正如JustSid所提到的，这个文件并不打算成为启animation面，而是用作第一个屏幕快照，以提高用户在应用程序加载时的体验。 检查人机界面指南

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