如何將RKObjectMapping（Reskit）轉換爲json字符串？

Question

我有以下代碼：

NSString *url =  @"http://mysite.com" 
RKURL *baseURL = [RKURL URLWithBaseURLString:url]; 
objectManager = [RKObjectManager objectManagerWithBaseURL:baseURL]; 
objectManager.client.baseURL = baseURL; 
objectManager.serializationMIMEType = RKMIMETypeJSON; 

NSString *token = @"Token is getting from rest API" 
[[objectManager client] setValue:token forHTTPHeaderField:@"token"]; 

RKClient *client= [objectManager client];  
RKRequest * therequest = [client requestWithResourcePath:@"/create"]; 


[therequest setHTTPBodyString:@"{user:user}"]; //Here receive a JSON value 
[therequest setMethod:RKRequestMethodPOST]; 
[therequest setDelegate:self];        
[therequest send]; 

此代碼工作正常...但我有一個問題，我需要發送到REST API JSON對象（如String），我有值的RKObjectMapping應該發送到Rest Api。

有可能將RKObjectMapping轉換爲JSON？

除非您自己編寫JSON庫，否則您無法在本地執行此操作。否則，考慮利用諸如JSONKit之類的東西，它很容易使用並且運行良好。

Here's an example usage。
