UITableView布局不刷新，直到滚动

Question

我创建了一个UISplitViewApplication作为我的新项目。在potrait模式下，我有一个按钮，点击后会下拉UITableView。它看起来如下所示：

当我点击了行之一，这是的UITableView驳回。后来，当我再次点击组按钮，呈现的UITableView的布局，现在所有的凌乱：

然而，当我滚动的TableView使一些行被重新装入，那些然后重新加载格式正常。为什么是这个以及如何解决这个问题？

这里是在索引路径为我行单元格：

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
    static NSString *CellIdentifier = @"MyCell"; 

    MyCell *cell = (ConvoreCell *) [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; 
    //if (cell == nil) { 
     NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"MyCell" owner:nil options:nil]; 
     for (id currentObject in topLevelObjects){ 
      if ([currentObject isKindOfClass:[UITableViewCell class]]){ 
       cell = (MyCell *) currentObject; 
       break; 
      } 
     } 
     cell.delegate = self; 
    // } 


    if ([posts count] > 0){ 
     cell.star.hidden = YES; 

     [lazyImages addLazyImageForCell:cell withIndexPath:indexPath]; 
     cell.title.text = [[posts objectAtIndex:indexPath.row] message]; 

     cell.detailed.autoresizesSubviews = YES; 
     cell.detailed.text = [NSString stringWithFormat:@"%@", [[[posts objectAtIndex:indexPath.row] creator] username]]; 


     if ([[[posts objectAtIndex:indexPath.row] embeds] count] != 0){ 
      NSString * URL = [[[[posts objectAtIndex:indexPath.row] embeds] objectAtIndex:0] url]; 
      float height = [[(Embed *)[[[posts objectAtIndex:indexPath.row] embeds] objectAtIndex:0] height] floatValue]; 
      float width = [[(Embed *)[[[posts objectAtIndex:indexPath.row] embeds] objectAtIndex:0] width] floatValue]; 
      [cell.embed setFrame:CGRectMake(cell.detailed.frame.origin.x, cell.detailed.frame.origin.y + 15, width, height)]; 
      cell.embed.image = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:URL]]]; 
     } 

     if ([[[posts objectAtIndex:indexPath.row] stars] count] != 0){ 
      cell.star.hidden = NO; 
      cell.star_creator.text = [(Login *)[[[[posts objectAtIndex:indexPath.row] stars] objectAtIndex:0] user] username]; 
     } 

    } 
    return cell; 
} 

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
    NSString *cellText =[[posts objectAtIndex:indexPath.row] message]; 
    UIFont *cellFont = [UIFont fontWithName:@"Arial" size:14.0]; 
    CGSize constraintSize = CGSizeMake(600.0f, MAXFLOAT); 
    CGSize labelSize = [cellText sizeWithFont:cellFont constrainedToSize:constraintSize lineBreakMode:UILineBreakModeWordWrap]; 
    float height = 0.0; 

    if ([[[posts objectAtIndex:indexPath.row] embeds] count] != 0) 
     height = [[[[[posts objectAtIndex:indexPath.row] embeds] objectAtIndex:0] height] floatValue]; 

    if (labelSize.height + 20 + height < 48) 
     return 55; 
    else 
     return labelSize.height + height + 48; 

}

我经历过在此之前，在你CellForRowAtIndex委托，如果电池等于零只是不停不检查。

更新从之前的评论

NSString *sIdentifier = [NSString stringWithFormat:@"MyIdentifier %i", indexPath.row]; 
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:sIdentifier]; 

    // don't check if(cell == nil) 
    cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:sIdentifier] autorelease];
