iphone – 如何使用来自xib文件的任何Subview(在xib中创建)的多

我有多个UIView IBoutlet的对象.

IBOutlet UIView *viewOpenDoor;
IBOutlet UIView *viewOpenDoor_Second;

viewOpenDoor仅连接到xib中的一个视图.
现在我使用此代码在viewdidload方法中多次重用相同的视图 –

[viewOpenDoor setFrame:CGRectMake(30,80,viewOpenDoor.frame.size.width,viewOpenDoor.frame.size.height)];
[self.view addSubview:viewOpenDoor];
viewOpenDoor.layer.borderColor = [UIColor blackColor].CGColor;
viewOpenDoor.layer.borderWidth = 0.9f;
viewOpenDoor.layer.cornerRadius = 6.0f;

 [viewOpenDoor setHidden:YES];

viewOpenDoor_Second = [[UIView alloc] init];
viewOpenDoor_Second = [viewOpenDoor copy];

[viewOpenDoor_Second setFrame:CGRectMake(184,viewOpenDoor.frame.size.height)];

[self.view addSubview:viewOpenDoor_Second];

它给予例外 –

-[UIView copyWithZone:]: unrecognized selector sent to instance 0x95ba140



Terminating app due to uncaught exception 'NSInvalidArgumentException',reason: '-[UIView copyWithZone:]: unrecognized selector sent to instance 0x95ba140'

所以,我的问题是如何重用这个在xib中创建的IBOutlet对象,多次使用不同的实例？
