我使用IB和Storyboard在UITableView中创建了一个自定义单元格。下面的代码是加载该自定义单元格的代码;问题是虽然cA.cBusName和cA.cOrderDate中有有效数据,但是单元格标签(cell.busNameLabel.text,cell.orderDateLagbel.text)没有设置。 问题是:为什么这不起作用?

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

    static NSString *CellIdentifier = @"CustomerListingsCell";

    CustomerListingsCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[CustomerListingsCell alloc]
                initWithStyle:UITableViewCellStyleDefault 
                reuseIdentifier:CellIdentifier];
    }

    // Configure the cell...
    SingletonListOfCustomers *shareInstance = [SingletonListOfCustomers sharedInstance];
    cArray *cA = [shareInstance.listOfCustomers objectAtIndex: indexPath.row];

    cell.busNameLabel.text = cA.cBusName;
    cell.orderDateLabel.text = cA.cOrderDate;

    NSLog(@"\n\nindexPath.row: %d, busNameLabel: %@, orderDateLabel: %@", indexPath.row, cA.cBusName, cA.cOrderDate);
    NSLog(@"\nindexPath.row: %d, cell.busNameLabel: %@, cell.orderDateLabel: %@", indexPath.row, cell.busNameLabel.text, cell.orderDateLabel.text);

    return cell;

}

CustomerListingsCell定义为:

@interface CustomerListingsCell : UITableViewCell  {

}

@property (nonatomic, strong) IBOutlet UILabel *busNameLabel;
@property (nonatomic, strong) IBOutlet UILabel *orderDateLabel;

@end

NSLog语句输出为:

indexPath.row:0,busNameLabel:Hidden Stitches,orderDateLabel:   05/24/2012 2012-05-24 14:01:55.364空白面料[4876:f803]   indexPath.row:0,cell.busNameLabel:(null),cell.orderDateLabel:   (null)2012-05-24 14:01:55.365空白面料[4876:f803]

     

indexPath.row:1,busNameLabel:Prager,Software,orderDateLabel:   05/24/2012 2012-05-24 14:01:55.373空白面料[4876:f803]   indexPath.row:1,cell.busNameLabel:(null),cell.orderDateLabel:   (空)

答案 0 :(得分:1)

您的IBOutlets是否都设置了两个标签?检查cell.busNameLabel是否不是......
