Question

我正在尝试将UITapGestureRecognizer附加到我正在创建的webview，然后在用户点击webview时删除该视图。以下是我的示例代码。我究竟做错了什么？谢谢！

- (void) setupPuzzle1
{
puzzleDuration--;
//Create object circle
UIImageView *circleView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"red-circle.png"] highlightedImage:[UIImage imageNamed:@"red-circle.png"]];

UITapGestureRecognizer *recognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(removeImage:)];
recognizer.numberOfTapsRequired = 1;
recognizer.numberOfTouchesRequired = 1;
recognizer.delegate = self;

[circleView addGestureRecognizer:recognizer];

[recognizer release];

int x = rand()%280;
int y = rand()%420;

circleView.frame = CGRectMake(x,y,40,40);
[self.view addSubview:circleView];

if (puzzleDuration > 0)
{
    [NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(setupPuzzle1) userInfo:nil repeats:NO];
}

}



#pragma mark - UITapGestureRecognizer methods


- (void)removeImage:(UITapGestureRecognizer *)recognizer
{
NSLog(@"Remove Image");
[[recognizer view] removeFromSuperview];
}

@end

我认为你根本不是在谈论UIWebView。如果你这样做，你的代码没有反映出来。因此，您正在处理UIImageView，原因非常简单，因为默认情况下任何UIImageView对象都将userInteractionEnabled设置为NO。您应该将其更改为YES。所以添加这一行，

circleView.userInteractionEnabled = YES;

你也没有发布它。所以添加

[circleView release];

将其添加为子视图后。

我如何将点击事件附加到uiwebview？
