iphone - 如何将 NSMutableDictionary 值复制到 iPhone 中的另一个 NSMutableDictionary 中？

Question

我想将 NSMUtableDictionary 值复制到另一个 NSMutableDictionary 中。我怎样才能做到这一点？

这是我的代码，

 PersonClass.h file:

 NSMutableDictionary *tempDictionary;
 @property (nonatomic, retain) NSMutableDictionary *tempDictionary;

 PersonClass.m
 @synthesize tempDictionary; 

 tempDictionary = [[NSMutableDictionary alloc] init];

-(PersonClass *) initWithPerson:(NSMutableDictionary *) feedDictionary
{
     // get all the values in feedDictionary.

     //Now i want copy of the details from feedDictionary into the tempDictionary

           tempDictionary = feedDictionary; // Doesn't copy.
}

我想访问 person 类的 tempDictionary 值。那么我如何从 feedDictionary 复制到 tempDictionary。请帮帮我。

谢谢。
