UITapgestureRecogniser in tableViewCell

Question

我在显示电话号码的UITableViewCell中有一个UILabel。当我点击它时，我应该能够打电话到那个特定的号码。因此，为了使它可点击，我添加了一个UITapGestureRecognizer，但我不知道如何参考哪个点击被点击，我的意思是哪个数字被点击。

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    lblphone = [[UILabel alloc] initWithFrame:CGSizeMake(20,30,50,100)];
    lblphone.tag = 116;
    lblphone.backgroundColor = [UIColor clearColor];
    lblphone.text=[NSString stringwithFormat:@"%@",phone];
    [lblphone setFont:[UIFont fontWithName:@"Helvetica" size:12]];
    [lblphone setLineBreakMode:UILineBreakModeWordWrap];
    [lblphone setUserInteractionEnabled:YES];
    UITapGestureRecognizer *tapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(labelButton:)];
    [tapGestureRecognizer setNumberOfTapsRequired:1];
    [lblphone addGestureRecognizer:tapGestureRecognizer];
    [tapGestureRecognizer release];
    [cell addSubview:lblphone];
}
-(IBAction)labelButton:(UITapGestureRecognizer*)tapGestureRecognizer
{
    NSIndexPath *indexPath;
    UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:indexPath];
    UILabel *phoneno = (UILabel*)[cell viewWithTag:116];
    NSString *phoneNumber = [@"telprompt://" stringByAppendingString:phoneno.text];
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:phoneNumber]];
}

但每次我都能看到NSString *phoneNumber最后一个cell的电话号码;

如何查看在UITapGestureRecognizer中单击了哪个标签?

Answer 1

在cellForRowAtIndexPath中用lblphone.tag = indexPath.row + 1;代替lblphone.tag = 116;

你也可以不使用标签来达到这个目的。

参见下面的示例

-(void)labelButton:(UITapGestureRecognizer*)tapGestureRecognizer
{
   UILabel *phoneno = (UILabel *) tapGestureRecognizer.view;
}
