JSON解析与RestKit

单字符串元素的列表如何配置RestKit解析此JSON：JSON解析与RestKit

{"platform":["This field is required."],"push_token":["This field is required."]}

可以在此JSON的RestKit支持不同的各套场的？如示例所示，只有一个字段“平台”或一个字段“push_token”或两个字段。

UPD：

@interface Register : NSObject 

@property (nonatomic, copy) NSString * platform; 
@property (nonatomic, copy) NSString * push_token; 

+ (void) initEntityForRestKit; 
+ (NSString *) getURL; 
+ (NSDictionary*) elementToPropertyMappings; 
+ (RKObjectMapping *) entityMapping; 

@end 

@implementation Register 

+ (NSString *) getURL { 
    return @"/api/register/"; 
} 

+ (void) initEntityForRestKit { 
    RKResponseDescriptor *responseFaultDescriptor = [RKResponseDescriptor 
                responseDescriptorWithMapping:[Register entityMapping] 
                pathPattern:[Register getURL] 
                keyPath:nil 
                statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassClientError)]; 
    [[RKObjectManager sharedManager] addResponseDescriptor:responseFaultDescriptor]; 
} 

+ (NSDictionary*)elementToPropertyMappings { 
    return @{@"platform":@"platform", 
      @"push_token":@"push_token"}; 
} 

+ (RKObjectMapping *) entityMapping { 
    RKObjectMapping *mapping = [RKObjectMapping mappingForClass:[Register class]]; 
    [mapping addAttributeMappingsFromDictionary:[Register elementToPropertyMappings]]; 

    return mapping; 
} 

@end

不清楚你在问什么，告诉你正在试图映射到类定义。 – Wain

@完成了。但是这段代码不起作用:) – ftp27

在这里感到困惑，你是说上面的代码不能解析你上面提到的json吗？或者你只是问上面的代码是否适合你的目的？ –

我刚才检查的Restkit的源代码。如果它是一个错误响应，它总是会返回一个错误。你可以根据你的情况调试下面的代码。

// If the response is a client error return either the mapping error or the mapped result to the caller as the error 
if (isErrorStatusCode) { 
    if ([self.mappingResult count] > 0) { 
     error = RKErrorFromMappingResult(self.mappingResult); 
    } else { 
     // We encountered a client error that we could not map, throw unprocessable error 
     if (! error) error = RKUnprocessableErrorFromResponse(self.response); 
    } 
    self.error = error; 
    [self willFinish]; 
    return; 
}

您可以在这里找到的代码https://github.com/RestKit/RestKit/blob/development/Code/Network/RKResponseMapperOperation.m#L378
