奇怪的結果與自動UITableViewCellHeight

我幾乎成功地集成了自動UITableViewCellHeight thingy，但一件事情很奇怪。如果我運行它，它會顯示第三部分中的第一部分的文本（也是第一部分中的內容）。有想法該怎麼解決這個嗎？奇怪的結果與自動UITableViewCellHeight

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

你真的* *應適當類的UITableViewCell，不重新設置所有這些內容的兩倍！然後將高度計算權建立到單元中，然後再調用。代碼少，清潔，少車。 – steipete

是的，你顯然是對的。我只是試圖讓我的頭與此。 – mstottrop

嘗試使用不同CellIdentifiers每個部分

static NSString *CellIdentifier; 
switch(indexPath.section){ 
    case 0: 
     CellIdentifier = @"first"; 
     break; 
    case 1: 
     CellIdentifier = @"second"; 
     break; 
    case 2: 
     CellIdentifier = @"third"; 
}
