可能重复：
此类与键的键值编码不兼容

代码

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
   return self;
}

输出

在界面生成器中打开 xib 文件。在最右边的视图打开的连接面板（带箭头的磁盘）上，连接上可能会有一个感叹号，称为“drawSign”。删除或重新连接它

I agree with paras joshi. Just check the class names again. Changing to the correct class names should resolve the problem. Or try reassigning the classes.

用 xib 检查类名，这是由于您的ReaderDeployment类或 xib 在项目中不可用，所以只需检查它并给出正确的名称..

有关更多详细信息，请参阅this 可能您可以从中获得想法..
