Question

在第13行之后无法加载UITableView行。数据再次从0重新加载。我发现行已加载到13行。然后行将从头开始。

如果我将每行的高度设置为20.所有行都可以在一个屏幕中加载，然后一切都很好。

但是我需要将高度设置为40.然后就会出现问题。

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *MyIdentifier = @"GroupsCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier];
if (cell == nil) {
    NSLog(@"test indexpath = %ld",(long)indexPath.row);
    cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault  reuseIdentifier:MyIdentifier];
}
if(indexPath.row == 0){
    UIImageView *profileImageView = [[UIImageView alloc] initWithFrame:CGRectMake(10.0, 10, 80.0, 80.0)];
    NSString *url = [[NSString alloc] init];
    NSString *tempurl =self.iconimgpath;
    NSLog(@"tempurl = %@",tempurl);
    url = [NSString stringWithFormat:@"%@",tempurl];
    NSURL * imageURL = [NSURL URLWithString:url];
    profileImageView.contentMode = UIViewContentModeScaleAspectFit;
    [profileImageView sd_setImageWithURL:imageURL placeholderImage:[UIImage imageNamed:@"loadinglogo.png"]];

    profileImageView.tag = 11;
    if([cell.contentView viewWithTag:11])
        [[cell.contentView viewWithTag:11] removeFromSuperview];
    [cell.contentView addSubview:profileImageView];
    //[cell.contentView addSubview:profileImageView];



}
else{
        if(_feedItems.count>0 && (indexPath.row > 0))
            {

                UILabel * groupnamelabel = [[UILabel alloc] initWithFrame:CGRectMake(10.0, 15.0, 300,20)];
                groupnamelabel.text = [_feedItems[indexPath.row-1] groupname];
                //groupnamelabel.font = [UIFont fontWithName:@"TrebuchetMS-Bold" size:18];
                groupnamelabel.tag = 99;
                if([cell.contentView viewWithTag:99]){
                    [[cell.contentView viewWithTag:99] removeFromSuperview];
                }
                [groupnamelabel setFont:[UIFont systemFontOfSize:15]];
                [cell.contentView addSubview:groupnamelabel];


                    UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(pushAction:)];
                    [groupnamelabel addGestureRecognizer:tap];
                    groupnamelabel.userInteractionEnabled = YES;

            }
    }

return cell;

我发现问题是

self.MyGrouptableview = [[UITableView alloc] initWithFrame:CGRectMake(0,65,screenWidth,screenHeight-150) style:UITableViewStylePlain];

如果我将tableview的高度设置得足够长，一切都会好的，但用户无法滚动到底部。

无法正确加载tableview行
