本文介绍如何在Objective-C中实现对象与JSON之间的相互转换。包括定义对象类的方法以从JSON初始化对象及将对象转化为JSON字符串的过程。

Define two methods in an object class as follows:

@interface MyObject : NSObject
@property (nonatomic,copy) NSString *property;

- (id)initWithJson:(NSDictionary *)item;
- (id)proxyForJson;

- (id)initWithJson:(NSDictionary *)item {  
   self = [superinit];
   if (self) {
       self.property = [itemobjectForKey:@"Property"];
    }
    return self;
}

- (id) proxyForJson {
    return [NSDictionarydictionaryWithObjectsAndKeys:property,@"Property",
            nil];
}

Convert json to object

   NSData *dataReply = [NSURLConnectionsendSynchronousRequest:urlRequest returningResponse:&response error:&error];

   NSDictionary *results = [dataReply JSONValue];
    
   MyObject *object = [[MyObjectalloc] initWithJson:results];

Convert object to json string

MyObject *object = [[MyObjectalloc]init];

NSString*json = [objectJSONRepresentation];
