[Cocoa]_[初级]_[如何复制NSView]

场景:

1. 一般我们使用ib设计器设计好一个NSView之后(通常用NSView组合多个控件), 需要复制一个NSView来重新布局显示.

如果调用[view copy] 消息的话会抛异常.

[XXView copyWithZone:]: unrecognized selector sent to instance 0x600000124240

解决办法就是使用 NSKeyedArchiver 档案来序列化之后再用 NSKeyedUnarchiver 还原.

NSData * archivedView = [NSKeyedArchiver archivedDataWithRootObject:productView];
    DhProductView * myViewCopy = [[NSKeyedUnarchiver unarchiveObjectWithData:archivedView] retain];
