解决方法:自定义textField,给textField添加NSIndexPath类型的属性indexPath。我们这次给textField的indexPath赋值而不是tag。...有可能冲突 // cell.contentTextField.tag = indexPath.row; // 所以传递indexPath,相当于把section也传递给contentTextField...cell.contentTextField.indexPath = indexPath; return cell; } 监听到通知后调用的方法 // 在这个方法中,我们就可以通过自定义.../** * indexPath属性用于区分不同的cell */ @property (strong, nonatomic) NSIndexPath *indexPath; @end 给自定义cell...作为协议方法的参数传进去 4>数据源方法cellForRowAtIndexPath:中对cell的indexPath赋值为当前的indexPath。
