转：Assertion failure in -[UITableView _configureCellForDisplay:forIndexPath:]

Assertion failure in -[UITableView _configureCellForDisplay:forIndexPath:] 今天做一个tableView遇到一个这么个问题。 经过baidu google，终于找到正解。 因为 - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath     *)indexPath 这个函数的返回值是个null！！ 查stackoverflow 找到下面的解。 CellIdentifier I bet your cellForRowAtIndexPath is returning null.  - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath     *)indexPath {     static NSString *CellIdentifier = @"Photos";      /** NOTE: This method can return nil so you need to account for that in code */     UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];      // NOTE: Add some code like this to create a new cell if there are none to reuse     if(cell == nil)     {         cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];      }      NSString *string = [[self.photosInPlace objectAtIndex:indexPath.row]     valueForKeyPath:@"description._content"];      cell.textLabel.text = string;      return cell; } That's probably why [UITableView _configureCellForDisplay:forIndexPath:] is failing... becausecellForRowAtIndexPath is returning a null value and then configureCellForDisplay is expecting aUITableViewCell.
