UITapGestureRecognizer* singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleSingleTap:)];
[self.view addGestureRecognizer:singleTap];　//這個可以加到任何控件上,比如你只想響應WebView，我正好填滿整個屏幕
singleTap.delegate = self;
singleTap.cancelsTouchesInView = NO;
[singleTap release]; - (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer
{
return YES;
}

如果沒有將自己賦值給UITapGestureRecognizer的委托，那么gestureRecognizer就不會被執行
