ios启动画面等待时间设定，以及动画效果

jxbgoph

delegate里面右个这个函数，只要它没结束，你的等待界面就不会消失。

可以在启动的时候做些动画

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

    

    // Override point for customization after application launch.

    [window addSubview:viewController.view];

    [self.window makeKeyAndVisible];

splashView = [[UIImageView alloc] initWithFrame:CGRectMake(0,0, 320, 480)];  

    splashView.image = [UIImage imageNamed:@"Default.png"];  

    [self.window addSubview:splashView];  

    [self.window bringSubviewToFront:splashView];  

    [UIView beginAnimations:nil context:nil];  

    [UIView setAnimationDuration:2.0];  

    [UIView setAnimationTransition:UIViewAnimationTransitionNone forView: self.window cache:YES];  

    [UIView setAnimationDelegate:self];   

    [UIView setAnimationDidStopSelector:@selector(startupAnimationDone:finished:context:)];  

    splashView.alpha = 0.0;  

    splashView.frame = CGRectMake(-60, -85, 440, 635);  

    [UIView commitAnimations];

    return YES;

}

- (void)startupAnimationDone:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context {

[splashView removeFromSuperview];

[splashView release];

}
