我用下面的代碼iPhoto的風格，左右滑動即可用UISwipeGestureRecognizer展現在我的應用程序的照片以類似的方式到iPhoto。「適應」我目前UISwipeGestureRecognizer代碼通過圖像彈到利用UIPanGestureRecognizer
CATransition *animation = [CATransition animation];
[animation setDuration:0.5];
[animation setType:kCATransitionPush];
[animation setSubtype:kCATransitionFromRight];
[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
[[self.imageHolder layer] addAnimation:animation forKey:@"SwitchToView"];
此滑動在下一圖像和舊圖像出像示於下面的照片：
圖像中的一個：
過渡：
圖片二：
我想知道如何使這個像iPhoto中時，我明白了，我應該使用一個UIPanGestureRecognizer代替。
我需要「控制」與我在iPhoto中做，順便手指動畫即通過讓我開始拖動到下一個圖像，然後反向拖動方向。此外，與iPhoto類似，如果在下一張圖像顯示的第一張圖像比下一張圖像更多時釋放手指，則希望下一張圖像能夠滑入（在上面的過渡圖片中未發生此情況，如果我已發佈。我的手指在iPhoto中這一點上，將滑回第一圖像
我以前從來沒有這樣，如果有人可以幫助我走出那簡直太好了使用UIPanGestureRecognizer
編輯：
使用由列維提供的代碼，我已經創建了與3樣本圖像很好地工作的解決方案。對於任何人埃爾斯Ë誰是有興趣在使用UIPanGestureRecognizer，代碼：
接口：

嗨。我希望能夠接受你的答案，因爲這聽起來像是我需要的，但是我做了一個新的項目，簡化了你的想法，但卻無法實現。請看看你是否有時間。 [下載鏈接]（http://rapidshare.com/files/1837376668/scrollTest.zip）'imageViewToPresent.view.center = nextCenter;'提供了一個錯誤，所以我想你的意思是'imageViewToPresent.center = nextCenter;'？然而，在這一行上給出了一個未使用的警告：'CGPoint center = recognizer.view.center;'如果你有機會，請看看我不想實現帶分頁的scrollView。謝謝 –
哇！非常感謝。明天我會檢查一下。歡呼聲 –
不客氣。目前它只能用於肖像模式。在風景中，圖像重疊。 – Levi
