UIImageView点按手势不适用于图像点按

Question

我已在表格页脚中分配了图片，点击仅在图片左上角的几个像素处被识别出来，但在图片上没有被识别。 您能在我做错的地方纠正我吗？ 我想在点击图像时调用方法。

这是代码。

-(UIView *) tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section
{    

if(section==1)
{
    UIView *headerView = [[UIView alloc] init];
    timgview = [[UIImageView alloc] initWithFrame:CGRectMake(285, 5, 20, 20)];
    timgview.image = [UIImage imageNamed:@"icon.png"];

    UITapGestureRecognizer *tapped = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(openURL:)];
    tapped.numberOfTapsRequired = 1;
    tapped.numberOfTouchesRequired = 1;
    [timgview addGestureRecognizer:tapped];
    timgview.userInteractionEnabled = YES;

    [headerView addSubview:timgview];

    return headerView;
 }
}

-(void)openURL:(id) sender
{
    NSLog(@"Opening URL");
}
