iPhone - 我怎麼可能趕上一個接進一個UIWebView或一個UIImageView

Question

我有一個觀點產生這樣的：

oneView = [[UIView alloc] initWithFrame:CGRectMake(x, y , w, h)]; 
oneView.tag = i; 

UITapGestureRecognizer* recognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleSingleTap2:)]; 
[recognizer setNumberOfTouchesRequired:1]; 
[oneView addGestureRecognizer:recognizer]; 
recognizer.delegate = self; 
[recognizer release]; 

- (void)handleSingleTap2:(UITapGestureRecognizer *)recognizer { 
    int viewID = recognizer.view.tag; 
    NSLog(@"id : %d", viewID); 
} 

這工作，但如果我有一個UIWebView或UIImageView的頁頭，然後更換了UIView ALLOC觸摸事件不再被觸發。

我該如何讓它工作？

Answer 1

集userInteractionEnabled = YES，如果需要multipleTouchEnabled = YES

Answer 2

關於你提到的有關UIWebView問題，我建議你看看drawnonward的答：

Does UIGestureRecognizer work on a UIWebView?

而爲的UIImageView部分見本教程：

UIImageView-with-zooming-tapping

我無法在這裏粘貼代碼，但我認爲這將使該區域更清潔，更易於閱讀。

Answer 3

必須覆蓋

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer;

委託功能和返回YES;
