RestKit에서 개체를 매핑하는 동안 오류가 발생합니다. 0.20

Question

Rest Kit 0.2o에서 작업 중이며 웹에서 Json 형식의 샘플 URL을 사용하고 있습니다. 응답은 아래와 같습니다. 개체 매핑을 사용하고 있습니다. 나는 아래의 링크를 참조로 사용하고있다. "https://github.com/RestKit/RestKit/wiki/Object-Mapping"나는 링크에서 주어진 것과 거의 같은 응답을 사용하고있다. 다음은

{ 
    "geonames": [ 
    { 
     "fcodeName":"capital of a political entity", 
     "toponymName":"Mexico City", 
     "countrycode":"MX", 
     "fcl":"P", 
     "fclName":"city, village,...", 
     "name":"Mexiko-Stadt", 
     "wikipedia":"en.wikipedia.org/wiki/Mexico_City", 
     "lng":-99.12766456604, 
     "fcode":"PPLC", 
     "geonameId":3530597, 
     "lat":19.428472427036, 
     "population":12294193 
    }, 
    { 
     "fcodeName":"capital of a political entity", 
     "toponymName":"Manila", 
     "countrycode":"PH", 
     "fcl":"P", 
     "fclName":"city,village,...", 
     "name":"Manila", 
     "wikipedia":"en.wikipedia.org/wiki/Manila", 
     "lng":120.9822, 
     "fcode":"PPLC", 
     "geonameId":1701668, 
     "lat":14.6042, 
     "population":10444527 
    }] 
} 

코드입니다

RKObjectMapping *newsMapping = [RKObjectMapping mappingForClass:[News class]]; 
[newsMapping addAttributeMappingsFromDictionary:@{ 
    @"fcodeName": @"fcodeName", 
    @"toponymName": @"toponymName", 
    @"countrycode": @"countrycode", 
    @"fcl": @"fcl", 
    @"fclName": @"fclName", 
    @"name":@"name", 
    @"wikipedia":@"wikipedia", 
    @"lng":@"lng", 
    @"fcode":@"fcode", 
    @"geonameId":@"geonameId", 
    @"lat":@"lat", 
    @"population":@"population", 
}]; 

RKResponseDescriptor* responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:newsMapping 
                        pathPattern:nil 
                         keyPath:@"newsMapping" 
                        statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)]; 

NSURL* url = [[NSURL alloc]initWithString:@"http://api.geonames.org/citiesJSON?north=44.1&south=-9.9&east=-22.4&west=55.2&lang=de&username=demo"]; 

NSURLRequest *request = [NSURLRequest requestWithURL:url]; 
RKObjectRequestOperation *objectRequestOperation = [[RKObjectRequestOperation alloc] initWithRequest:request responseDescriptors:@[ responseDescriptor ]]; 

[objectRequestOperation setCompletionBlockWithSuccess:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) { 
    RKLogInfo(@"Load collection of Articles: %@", mappingResult.array); 
} failure:^(RKObjectRequestOperation *operation, NSError *error) { 
    // RKLogError(@"Operation failed with error: %@", error); 
    NSLog(@"THIS IS TEST %@",error); 
}]; 

[objectRequestOperation start]; 

"뉴스는"모든 일을 한 후 "GeoNames을"

@interface News : NSObject

실제로 오류가 발생하면 마지막 줄에 keyPath가 null로 표시됩니다. 그러나 브라우저에서 나는 위에서 언급 한 응답을 얻고 있습니다.

도와주세요

Answer 1

응답 설명자 키 패스가 잘못되었습니다. 변경하려면 :

{"status":{"message":"the deaily limit of 30000 credits for demo has been exceeded. Please use an application specific account. Do not use the demo account for your application.","value":18}} 

당신이 기대하는 내용과 일치하지 않는 분명히 어떤 ...

: 실제로 반환 된 JSON이기 때문에

RKResponseDescriptor* responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:newsMapping pathPattern:nil keyPath:@"geonames" statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)]; 

현재보고있는 오류가 될 것 같다
