UITableViewCell不能正常顯示/從NIB中正確地重複使用

Question

我已經從NIB創建了一個自定義的UITableViewCell。當rowHeight沒有被設置時，所有東西都會出現（儘管一切都被壓扁了）。我不知道如果我再利用和妥善創建細胞：

// Customize the appearance of table view cells. 
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { 

    static NSString *MyIdentifier = @"ARCell"; 
    ARObject *myARObject; 
    myARObject = [items objectAtIndex:indexPath.row]; 

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier]; 
    if (cell == nil) { 
     [[NSBundle mainBundle] loadNibNamed:@"ARCell" owner:self options:nil]; 
     cell = arCell; 
     self.arCell = nil; 
    } 

    UILabel *label; 
    label = (UILabel *)[cell viewWithTag:0]; 
    label.text = [NSString stringWithFormat:@"%@", myARObject.username]; 

    label = (UILabel *)[cell viewWithTag:1]; 
    label.text = [NSString stringWithFormat:@"%@", myARObject.created_at]; 

    label = (UILabel *)[cell viewWithTag:2]; 
    label.text = [NSString stringWithFormat:@"%@", myARObject.articleTitle]; 

    label = (UILabel *)[cell viewWithTag:3]; 
    label.text = [NSString stringWithFormat:@"%@", myARObject.intro_text]; 

    return cell; 
} 

- (CGFloat)tableView:(UITableView *)tblView heightForRowAtIndexPath:(NSIndexPath *)indexPath 
{ CGFloat rowHeight = 105; 
    return rowHeight; 
} 

問題：

1. 不是當rowHeight時設置的所有標籤出現。如果沒有設置rowHeight時，標籤被壓扁
2. 當rowHeight時未設置，選擇一個項目顯示了所有標籤的

Answer 1

刪除else子句

Answer 2

你叫loadNibNamed，但不存儲結果無處不在不明白爲什麼你的代碼在所有工作...總之，寫瞎我會嘗試這樣的事：

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
    static NSString *MyIdentifier = @"ARCell"; 
    ARObject *myARObject = [items objectAtIndex:indexPath.row]; 

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier]; 
    if (cell == nil) { 
     NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"ARCell" owner:self options:nil]; 
     cell = (UITableViewCell *)[nib objectAtIndex:0]; 
    } 

    UILabel *label; 
    label = (UILabel *)[cell viewWithTag:0]; 
    label.text = [NSString stringWithFormat:@"%@", myARObject.username]; 

    label = (UILabel *)[cell viewWithTag:1]; 
    label.text = [NSString stringWithFormat:@"%@", myARObject.created_at]; 

    label = (UILabel *)[cell viewWithTag:2]; 
    label.text = [NSString stringWithFormat:@"%@", myARObject.articleTitle]; 

    label = (UILabel *)[cell viewWithTag:3]; 
    label.text = [NSString stringWithFormat:@"%@", myARObject.intro_text]; 

    return cell; 
} 

- (CGFloat)tableView:(UITableView *)tblView heightForRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
    return 105.0; 
}
