克隆或复制UIViewController或UIView [英] Clone or Copy UIViewController or UIView

问题描述

UII需要copy，self controller或self.view，我试过：

  UIView * viewOfSelf = [self.view复制]; 
 UIViewController * controller = [self copy]; 
 
 UIView * viewOfSelf = [self.view mutableCopy]; 
 UIViewController * controller = [self mutableCopy]; 
  

错误是：

   -  [UIViewController mutableCopyWithZone：]：无法识别的选择器发送到实例0xb803490 
  -  [UIView copyWithZone：]：无法识别的选择器发送到实例0x6e0acb0

解决方案
使用 -  
  NSData * tempArchiveView = [NSKeyedArchiver archivedDataWithRootObject：self.view]; 
 UIView * viewOfSelf = [NSKeyedUnarchiver unarchiveObjectWithData：tempArchiveView]; 
  
同样 -  
 code> NSData * tempArchiveViewController = [NSKeyedArchiver archivedDataWithRootObject：self]; 
 UIViewController * controller = [NSKeyedUnarchiver unarchiveObjectWithData：tempArchiveViewController]; 
  
 
UII need copy, self controller or self.view, i have tried:
UIView* viewOfSelf =[self.view copy];
UIViewController* controller = [self copy];

UIView* viewOfSelf =[self.view mutableCopy];
UIViewController* controller = [self mutableCopy];
The error is: 
    -[UIViewController mutableCopyWithZone:]: unrecognized selector sent to instance 0xb803490
    -[UIView copyWithZone:]: unrecognized selector sent to instance 0x6e0acb0

解决方案
Use - 
NSData *tempArchiveView = [NSKeyedArchiver archivedDataWithRootObject:self.view];
UIView *viewOfSelf = [NSKeyedUnarchiver unarchiveObjectWithData:tempArchiveView];
Similarly -
NSData *tempArchiveViewController = [NSKeyedArchiver archivedDataWithRootObject:self];
UIViewController *controller = [NSKeyedUnarchiver unarchiveObjectWithData:tempArchiveViewController];
