點擊手勢不起作用

我正在開發一個應用程序，用戶可以在其中添加一些圖標，如帽子，捕獲的圖片上的頭髮。爲此，我在屏幕上有一個圖像視圖來保存捕獲的圖像，在下面我有一個滾動視圖顯示用戶可以應用的各種圖標。當我點擊放置在滾動視圖中的任何圖標時，我需要將此圖標移動到中心捕獲的圖片，但是當我使用代碼嘗試時，會將圖像設置爲滾動視圖的中心而不是整個視圖。但是，當我刪除滾動視圖，並把圖像以外的圖像視圖這個作品。請建議。點擊手勢不起作用

這是來自ViewController或不同類的代碼嗎？ – Literphor

要添加tapgestuer你必須參考這個http://stackoverflow.com/questions/11355671/how-do-i-implement-the-uitapgesturerecognizer-into-my-application – Jay

您正在設置從self.view的中心圖像的中心，但我想你也必須採取滾動視圖幀從原點偏移的照顧。所以，你的image_15中心應設置像

self.image_15.center = CGPointMake(currentCenter.x-yourScrollView.frame.origin.x, currentCenter.y-yourScrollView.frame.origin.y);
（提供滾動型也是self.view直接子視圖）

我可以改進我的回答如果你提供我你的視圖層次incode細節。
