在objective-c中从NSDictionary创建NSObject [英] Create NSObject from NSDictionary in objective-c

问题描述

我想使用for ... in循环将字典中的每个项目分配到我的对象中

我有一个像这样的NSDictionary： p>

  {user_id：1，user_name：John} 
  
  
 
 
我有一个NSObject变量：
 
 pre $  NSString * user_id; 
 NSString * user_name 
  

使用for循环，我想从my我的NSObject中的NSDictionary

  for（NSString * param in userDictionary）{
 
} 
  

我该如何做？

















$ - （void）setValue：（id）value forKey：（NSString *）key;


例如：



  [userDictionary enumerateKeysAndObjectsUsingBlock：^（id key，id obj，BOOL * stop）{
 [myObject setValue：obj forKey：（NSString *）key]; 
}]; 
  




I would like to assign each item from a dictionary into my object using a "for...in" loop

I have a NSDictionary like that :

{"user_id" : "1", "user_name" : "John"}

And I have an NSObject with variable :

NSString *user_id;
NSString *user_name

With a for in loop, I want to assign each item from my NSDictionary in my NSObject

for (NSString *param in userDictionary) {

}

How I can do that ?

Thanks,

解决方案

Have a look at the NSObject class method:

- (void)setValue:(id)value forKey:(NSString *)key;

For example:

[userDictionary enumerateKeysAndObjectsUsingBlock:^(id key, id obj, BOOL *stop){
    [myObject setValue:obj forKey:(NSString *)key];
}];
