地图程序那样的Curl效果分享

看了很多例子的CurlUp和CurlDown，都是翻页效果，没有像地图那样翻到一半停下的，偶然在网上看到了方法，自己做了一个例子，不敢独享，拿出来大家看一下。
关键代码如下：

复制代码 - (IBAction)curlUp{     NSLog(@"Curl");     // Curl the image up or down     CATransition *animation = [CATransition animation];     [animation setDelegate:self];     [animation setDuration:0.35];     [animation setTimingFunction:UIViewAnimationCurveEaseInOut];     if (!curled){         animation.type = @"pageCurl";         animation.fillMode = kCAFillModeForwards;         animation.endProgress = 0.58;     } else {         animation.type = @"pageUnCurl";         animation.fillMode = kCAFillModeBackwards;         animation.startProgress = 0.42;     }     [animation setRemovedOnCompletion:NO];     [view exchangeSubviewAtIndex:0 withSubviewAtIndex:1];          [view addAnimation:animation forKey:@"pageCurlAnimation"];          // Disable user interaction where necessary     if (!curled) {              } else {              }          curled = !curled; }
