私はRESTKitを学習しており、以前のバージョンのRESTKitに準拠したこのチュートリアルに従っていますが、v0.20.0では多くの変更が加えられているため、新しいバージョンについて読み、チュートリアルと同じタスクを実行しています。
現在、マッピングに問題があり、私はそれに何時間も費やして成功しませんでした。私が得ているエラーは次のとおりです。
error: Error Domain=org.restkit.RestKit.ErrorDomain Code=1001 "No response descriptors match the response loaded."

Venue.hは：
#import <Foundation/Foundation.h>
@interface Venue : NSObject
@property (strong, nonatomic) NSString *name;
@end
Venue.mは：
#import "Venue.h"
@implementation Venue
@synthesize name;
@end
そして、私はViewDidAppearメソッドのMasterViewController.mですべてを実行しています。これは次のとおりです。
- (void) viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
NSURL *baseURL = [NSURL URLWithString:@"https://api.Foursquare.com/v2"];
AFHTTPClient * client = [AFHTTPClient clientWithBaseURL:baseURL];
[client setDefaultHeader:@"Accept" value:RKMIMETypeJSON];
RKObjectManager *objectManager = [[RKObjectManager alloc] initWithHTTPClient:client];
RKObjectMapping *venueMapping = [RKObjectMapping mappingForClass:[Venue class]];
[venueMapping addAttributeMappingsFromDictionary:@{
@"name" : @"name"
}];
RKResponseDescriptor * responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:venueMapping
pathPattern:nil
keyPath:@"response.venues"
statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];
[objectManager addResponseDescriptor:responseDescriptor];
NSString *latLon = @"37.33,-122.03";
NSString *clientID = [NSString stringWithUTF8String:kCLIENTID];
NSString *clientSecret = [NSString stringWithUTF8String:kCLIENTSECRET];
NSDictionary *queryParams;
queryParams = [NSDictionary dictionaryWithObjectsAndKeys:latLon, @"ll", clientID, @"client_id", clientSecret, @"client_secret", @"coffee", @"query", @"20120602", @"v", nil];
//NSLog(@"object manager: %@ - %@", objectManager.baseURL, [[objectManager responseDescriptors] objectAtIndex:0]);
/*
RKRelationshipMapping* relationShipMapping = [RKRelationshipMapping relationshipMappingFromKeyPath:@"venues"
toKeyPath:@"venues"
withMapping:venueMapping];
[venueMapping addPropertyMapping:relationShipMapping]; */
[objectManager getObjectsAtPath:@"https://api.Foursquare.com/v2/venues/search"
parameters:queryParams
success:^(RKObjectRequestOperation * operaton, RKMappingResult *mappingResult)
{
NSLog(@"success: mappings: %@", mappingResult);
}
failure:^(RKObjectRequestOperation * operaton, NSError * error)
{
NSLog (@"failure: operation: %@ \n\nerror: %@", operaton, error);
}];
}
ブラウザで応答を確認しましたが、問題はありませんが、何らかの理由でエラーを取り除くことができませんでした。マッピングの最初のステップで立ち往生していて、先に進むことができません。インターネット上の主題に関するすべての例とドキュメントは古く、RESTKitの古いバージョンの経験がないので私は物事を理解することができません。私が間違っていることを教えてください。
xcode4.5を使用してiOS6用にビルドします。
