Iphone 从阵列崩溃模拟器设置UITableViewCell

我已经尝试了很多事情来实现这一目标，但我完全失败了

我得到以下错误

-[\uu NSArrayM isEqualToString:]：发送到实例0x4d41210的选择器无法识别
2011-01-31 17:03:49.496 I故障[11954:207]***由于未捕获的异常“NSInvalidArgumentException”而终止应用程序，原因：'-[\uu NSArrayM isEqualToString::]：未识别的选择器发送到实例0x4d41210

我的代码如下所示

// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    NSLog(@"FIRST LINE ROW");
    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

    if (cell == nil) {

        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];

    }
    // Set up the cell...

     hold = [self.names objectAtIndex:[indexPath row]];
    //NSString *hold = [big objectAtIndex:indexPath.row];
    //NSLog(@"%@",hold);
    //hold = @"TEST TEST";
    cell.textLabel.font = [UIFont fontWithName:@"Helvetica" size:15];
    cell.textLabel.text = hold; 
    return cell;

}

如果我取消注释

hold=@“test test”

表将正确填充“test test”

抱歉，代码太多了，但我想如果我展示的更多，我可能会得到更多的帮助

我不知道是什么导致了这个错误。我的Json解析是正确的，我的名称数组在我想将其显示到完全分离的表时正确填充

愚蠢的是我在使用断点调试时所做的堆栈跟踪日志

问题是nss指出我的数据不是字符串。当我把它展示在桌子上时，我不得不投下它

cell.textLabel.text = [[self.names objectAtIndex:indexPath.row]description] 

---

关键字是description这将其强制转换为字符串

问题在于，无论您在哪里拥有isEqualToString：您都在对数组而不是字符串调用此方法。把代码贴在那里。我哪里都没有。我不在任何地方使用isEqualToString..你有完整的堆栈跟踪吗？那会有很大帮助。另外，您是否确认

NSLog（@“%@，[status objectForKey:@“Name]”）点击此行cell.textlab.text=hold时，它确实正在打印
NSStrings
；我在我的原始问题中发布了错误日志我很确定这是一个字符串，有没有办法测试它是否确实是一个字符串？当我不填充表格，但单击某一行时会显示一条警告消息，并在我的字符串显示为（“测试”）时显示hold对象，这是否会导致表格显示出现问题？
