ios - uitableviewcells 与 3 个重叠中的前 2 个单元重叠

Question

我一直试图弄清楚我的单元格是否重叠，但我失败了。我的表包含 3 个条目 - 前 2 个条目重叠，但第 3 个条目不重叠。我在网上搜索了一下，发现变量应该在本地定义。我采纳了这个建议，但遗憾的是，它没有帮助。

下面是代码:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    UIColor *rung;
    if (indexPath.row%2 == 0) {
      //  0.662745 0.662745 0.662745
        rung=[UIColor colorWithRed:0.802745 green:0.802745 blue:0.802745 alpha:1];
        color=NO;
    }
    else {
       // 0.972549 0.972549 1
    //0.411765 0.411765 0.411765
        rung=[UIColor colorWithRed:0.862745 green:0.862745 blue:0.862745 alpha:1];
        color=YES;
    }



    //static NSString *MyIdentifier = @"Identifier";
    NSLog(@"====IndexPath is %d",indexPath.row);

    ChatSlideDC *slide = [[HMMainManager getSharedInstance].currentMeeting.resumedChatMessages objectAtIndex:indexPath.section];


    ChatMessageDC *message;

    message = [[slide ChatMessageArray]objectAtIndex:indexPath.row];
    NSLog(@"%i",indexPath.row);

    NSLog(@"%@",message.senderEmail);
    NSLog(@"====Message Type is %@",message.MessageType);
    //--storing Email-ID for Pics
    UIImage *avatar;
    if(message.AttendeeID)
    {
        avatar= [(AppDelegate *)[[UIApplication sharedApplication]delegate] getAvatar:message.AttendeeID andAttendeEmail:message.senderEmail];
    }



    //
    NSLog(@"%@",message.Message);
    if ([message.MessageType isEqualToString: @"0"] || [message.MessageType isEqualToString:@"1"]) {
        ChatCustomCell * cell = (ChatCustomCell *) [tableView dequeueReusableCellWithIdentifier:@"ChatCustomCell"];

        if (cell == nil) {

            NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"ChatCustomCell" owner:self options:nil];
            cell = (ChatCustomCell*)[nib objectAtIndex:0];

如果您有自定义(非 44 点高度)单元格，则需要实现 - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
