Ios RestKit可以'；t使用'映射对象；空'；结果

我无法解决RestKit的

RestKit

问题。我正试图映射一个结果为

null

的对象，但由于某种原因，

RestKit

无法处理该对象。我知道我做错了什么，但我就是不知道是什么

这是我从服务中得到的响应：

@interface ResponseError : NSObject
@property (nonatomic,assign) NSInteger applicationErrorCode;
@property (nonatomic,strong) NSString *developerMessage;
@property (nonatomic,strong) NSString *userMessage;
@end

@interface ResponseWithError : NSObject
@property (nonatomic,strong) ResponseError *responseError;
@end

RKObjectMapping *responseErrorMapping = [RKObjectMapping mappingForClass:[ResponseError class]];
[responseErrorMapping addAttributeMappingsFromDictionary:@{ @"applicationErrorCode" : @"applicationErrorCode", @"developerMessage" : @"developerMessage",@"userMessage" : @"userMessage"}];

RKRelationshipMapping *responseErrorRelationMapping = [RKRelationshipMapping relationshipMappingFromKeyPath:@"responseError" toKeyPath:@"responseError" withMapping:responseErrorMapping];


RKObjectMapping *checkR = [RKObjectMapping mappingForClass:[ResponseWithError class]];
    [checkR addPropertyMapping:[responseErrorRelationMapping copy]];
    [[RKObjectManager sharedManager] addResponseDescriptor:[RKResponseDescriptor responseDescriptorWithMapping:checkR
method:RKRequestMethodPOST pathPattern:[RequestStringBuilder approveStatementChecks]  keyPath: nil
statusCodes: RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)]];

"No mappable object representations were found at the key paths searched."

{“responseError”：null}

这是ResponseError.h文件：

@interface ResponseError : NSObject
@property (nonatomic,assign) NSInteger applicationErrorCode;
@property (nonatomic,strong) NSString *developerMessage;
@property (nonatomic,strong) NSString *userMessage;
@end

@interface ResponseWithError : NSObject
@property (nonatomic,strong) ResponseError *responseError;
@end

RKObjectMapping *responseErrorMapping = [RKObjectMapping mappingForClass:[ResponseError class]];
[responseErrorMapping addAttributeMappingsFromDictionary:@{ @"applicationErrorCode" : @"applicationErrorCode", @"developerMessage" : @"developerMessage",@"userMessage" : @"userMessage"}];

RKRelationshipMapping *responseErrorRelationMapping = [RKRelationshipMapping relationshipMappingFromKeyPath:@"responseError" toKeyPath:@"responseError" withMapping:responseErrorMapping];


RKObjectMapping *checkR = [RKObjectMapping mappingForClass:[ResponseWithError class]];
    [checkR addPropertyMapping:[responseErrorRelationMapping copy]];
    [[RKObjectManager sharedManager] addResponseDescriptor:[RKResponseDescriptor responseDescriptorWithMapping:checkR
method:RKRequestMethodPOST pathPattern:[RequestStringBuilder approveStatementChecks]  keyPath: nil
statusCodes: RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)]];

"No mappable object representations were found at the key paths searched."

这是响应错误的.h文件：

@interface ResponseError : NSObject
@property (nonatomic,assign) NSInteger applicationErrorCode;
@property (nonatomic,strong) NSString *developerMessage;
@property (nonatomic,strong) NSString *userMessage;
@end

@interface ResponseWithError : NSObject
@property (nonatomic,strong) ResponseError *responseError;
@end

RKObjectMapping *responseErrorMapping = [RKObjectMapping mappingForClass:[ResponseError class]];
[responseErrorMapping addAttributeMappingsFromDictionary:@{ @"applicationErrorCode" : @"applicationErrorCode", @"developerMessage" : @"developerMessage",@"userMessage" : @"userMessage"}];

RKRelationshipMapping *responseErrorRelationMapping = [RKRelationshipMapping relationshipMappingFromKeyPath:@"responseError" toKeyPath:@"responseError" withMapping:responseErrorMapping];


RKObjectMapping *checkR = [RKObjectMapping mappingForClass:[ResponseWithError class]];
    [checkR addPropertyMapping:[responseErrorRelationMapping copy]];
    [[RKObjectManager sharedManager] addResponseDescriptor:[RKResponseDescriptor responseDescriptorWithMapping:checkR
method:RKRequestMethodPOST pathPattern:[RequestStringBuilder approveStatementChecks]  keyPath: nil
statusCodes: RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)]];

"No mappable object representations were found at the key paths searched."

这是对象的映射：

@interface ResponseError : NSObject
@property (nonatomic,assign) NSInteger applicationErrorCode;
@property (nonatomic,strong) NSString *developerMessage;
@property (nonatomic,strong) NSString *userMessage;
@end

@interface ResponseWithError : NSObject
@property (nonatomic,strong) ResponseError *responseError;
@end

RKObjectMapping *responseErrorMapping = [RKObjectMapping mappingForClass:[ResponseError class]];
[responseErrorMapping addAttributeMappingsFromDictionary:@{ @"applicationErrorCode" : @"applicationErrorCode", @"developerMessage" : @"developerMessage",@"userMessage" : @"userMessage"}];

RKRelationshipMapping *responseErrorRelationMapping = [RKRelationshipMapping relationshipMappingFromKeyPath:@"responseError" toKeyPath:@"responseError" withMapping:responseErrorMapping];


RKObjectMapping *checkR = [RKObjectMapping mappingForClass:[ResponseWithError class]];
    [checkR addPropertyMapping:[responseErrorRelationMapping copy]];
    [[RKObjectManager sharedManager] addResponseDescriptor:[RKResponseDescriptor responseDescriptorWithMapping:checkR
method:RKRequestMethodPOST pathPattern:[RequestStringBuilder approveStatementChecks]  keyPath: nil
statusCodes: RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)]];

"No mappable object representations were found at the key paths searched."

这是我从RestKit得到的错误：

@interface ResponseError : NSObject
@property (nonatomic,assign) NSInteger applicationErrorCode;
@property (nonatomic,strong) NSString *developerMessage;
@property (nonatomic,strong) NSString *userMessage;
@end

@interface ResponseWithError : NSObject
@property (nonatomic,strong) ResponseError *responseError;
@end

RKObjectMapping *responseErrorMapping = [RKObjectMapping mappingForClass:[ResponseError class]];
[responseErrorMapping addAttributeMappingsFromDictionary:@{ @"applicationErrorCode" : @"applicationErrorCode", @"developerMessage" : @"developerMessage",@"userMessage" : @"userMessage"}];

RKRelationshipMapping *responseErrorRelationMapping = [RKRelationshipMapping relationshipMappingFromKeyPath:@"responseError" toKeyPath:@"responseError" withMapping:responseErrorMapping];


RKObjectMapping *checkR = [RKObjectMapping mappingForClass:[ResponseWithError class]];
    [checkR addPropertyMapping:[responseErrorRelationMapping copy]];
    [[RKObjectManager sharedManager] addResponseDescriptor:[RKResponseDescriptor responseDescriptorWithMapping:checkR

提前谢谢。

@Wain，也许你知道如何解决这个问题？服务器返回的状态码是400-499范围内的HTTP错误码吗？
