您能將UIGestureRecognizer附加到多個視圖嗎？UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:
self action:@selector(tapTapTap:)];[self.view1 addGestureRecognizer:tapGesture];
[self.view2 addGestureRecognizer:tapGesture];[tapGesture release];在上面的代碼中，只點擊view2都被認(rèn)可了。如果我注釋掉第三行，然后點擊view1都被認(rèn)可了。如果我是對的，而且您只能使用手勢識別器一次，我不確定這是否是一個錯誤，或者它只是需要更多的文檔。
