我的tableview单元格内容在滚动和重新加载数据时重复。
我也知道将重用标识符更改为nill会解决问题，但由于此链接中提到的原因我需要使用重用标识符IOS 7 UITextField resignFirstResponder BAD
有没有其他方法可以解决重复问题（以及重复使用单元格）
这是我的代码

答案 0 :(得分：-1)
Profile Cell是一个UITableViewCell。你不能用视图分配它。而不是使用
ProfileCell *profilecell = (ProfileCell *)[tableView dequeueReusableCellWithIdentifier:ProfileTableIdentifier];
if (profilecell == nil)
{
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"ProfileCell" owner:self options:nil];
profilecell = [nib objectAtIndex:0];
}
只使用一行
[[NSBundle mainBundle] loadNibNamed:@"ProfileCell" owner:self options:nil];
