技巧-使用翻转效果

//翻转效果：
    CATransition *animation = [CATransition animation];//准备动画
    [animation setDuration:0.3f];////动画播放持续时间
    //动画速度,何时快、慢:
    [animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseIn]];
    [animation setType:kCATransitionPush];//动画效果    
    [animation setSubtype:kCATransitionFromLeft];//动画方向

    MyBabyViewController *myBabyViewController = [[MyBabyViewController alloc] initWithNibName:@"MyBabyViewController" bundle:nil]; 
    [myBabyViewController.view.layer addAnimation:animation forKey:@"animationID"];
    [self.view.window addSubview:myBabyViewController.view];
