当在 tableviewcell 中单击 imageview 时，我必须调用特定号码。调用的号码显示在 imageview 旁边的标签中。但我无法获得单击的单元格。始终它指的是最后一个单元格。

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{

    if(cell == nil)
    {
        cell =[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault  reuseIdentifier:CellIdentifier];
        lblphone = [[UILabel alloc] initWithFrame:CGRectZero];
        lblphone.tag = 116;
        lblphone.backgroundColor = [UIColor clearColor];
        [lblphone setFont:[UIFont fontWithName:@"Helvetica" size:12]];
        [lblphone setLineBreakMode:UILineBreakModeWordWrap];
        [lblphone setUserInteractionEnabled:YES];

        UITapGestureRecognizer *tapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(labelButton:)];
        tapGestureRecognizer.cancelsTouchesInView=NO;
        [tapGestureRecognizer setNumberOfTapsRequired:1];
        [lblphone addGestureRecognizer:tapGestureRecognizer];
        [tapGestureRecognizer release];
        [cell addSubview:lblphone];

        myImageView = [[UIImageView alloc] initWithFrame:CGRectZero];
        myImageView.tag = 120;
        myImageView.image=[UIImage imageNamed:@"CallImg.png"];

        UITapGestureRecognizer *tapped = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(imageSelectedInTable:)];
        [tapped setNumberOfTapsRequired:1];
        [myImageView addGestureRecognizer:tapped];
        [tapped release];
        [cell addSubview:myImageView];
    }

    [myImageView setFrame:CGRectMake(10, 50,30,30)];
    myImageView= (UIImageView*)[cell viewWithTag:120];
    myImageView.image=[UIImage imageNamed:@"CallImg.png"];
    myImageView.userInteractionEnabled=YES;

    CGSize constraint5 = CGSizeMake(320, 2000.0f);
    CGSize size5=[phone sizeWithFont:[UIFont fontWithName:@"Helvetica" size:14] constrainedToSize:constraint5 lineBreakMode:UILineBreakModeWordWrap];
    lblphone =(UILabel *)[cell viewWithTag:116];
    [lblphone setFrame:CGRectMake(45,name.frame.size.height+name.frame.origin.y,320, size5.height)];
    lblphone.textAlignment=UITextAlignmentLeft;
    lblphone.backgroundColor=[UIColor clearColor];
    lblphone.text=[NSString stringWithFormat:@"%@ ",phone ];
    [lblphone sizeToFit];
}

在 imageclick 的点击手势中，我正在写这个:

-(IBAction)imageSelectedInTable:(UITapGestureRecognizer*)gesture
{
    UIImageView *imgView = (UIImageView *) [gesture view];
    UITableViewCell *cell = (UITableViewCell*)[[imgView superview]superview];
    NSIndexPath *tappedIndexPath = [self.tableView indexPathForCell:cell];
    NSLog(@"Image Tap %@", tappedIndexPath);
    UILabel *phoneno = (UILabel *)[cell viewWithTag:116];

    NSString *phoneNumber = [@"telprompt://" stringByAppendingString:phoneno.text];
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:phoneNumber]];
}

但无论单击哪个单元格，它总是引用最后一个单击的单元格。无法理解我哪里出错了？

最佳答案

我看到你试图访问你的手机，

UITableViewCell *cell = (UITableViewCell*)[[imgView superview]superview];

但是您将 ImageView 添加到

[cell addSubview:myImageView];

您应该将 ImageView 添加到 cell.contentView。
