你不能不使用它将实现的一些技巧

打开你的AppDelegate.m并将下面的代码添加到你的应用程序didFinishLaunching或application didFinishLaunchingWithOptions函数中：

 //1. add the image to the front of the view... UIImageView *splashImage = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)]; [splashImage setImage: [UIImage imageNamed:@"Default"]]; [self.window addSubview:splashImage]; [self.window bringSubviewToFront:splashImage]; //2. set an anchor point on the image view so it opens from the left splashImage.layer.anchorPoint = CGPointMake(0, 0.5); //reset the image view frame splashImage.frame = CGRectMake(0, 0, 320, 480); //3. animate the open [UIView animateWithDuration:1.0 delay:0.6 options:(UIViewAnimationCurveEaseOut) animations:^{ splashImage.layer.transform = CATransform3DRotate(CATransform3DIdentity, -M_PI_2, 0, 1, 0); } completion:^(BOOL finished){ //remove that imageview from the view [splashImage removeFromSuperview]; }];
