我正在尝试学习restkit,现在正在研究对象映射。这是我尝试接收和处理的 JSON(由 ASP.NET MVC Web API 生成):
[
{
"Id": 0,
"Title": "Test",
"Location": "Test",
"Score": {
"Hill": 10,
"LVille": 12
},
"TimeStart": "2012-11-10T12:30:00",
"TimeEnd": "2012-11-10T13:20:00",
"Gender": 0,
"State": 0
},
{
"Id": 0,
"Title": "ee",
"Location": "12:00",
"Score": {
"Hill": 13,
"LVille": 0
},
"TimeStart": "12:00 PM",
"TimeEnd": "12:00 PM",
"Gender": 1,
"State": 1
}
]
被映射到的对象是(SBGame):
@interface SBGame : NSObject
@property (nonatomic, copy) NSNumber* Id;
@property (nonatomic, copy) NSString* Title;
@property (nonatomic, copy) NSString* Location;
@property (nonatomic, strong) SBScore* Score;
@property (nonatomic, copy) NSString* TimeStart;
@property (nonatomic, copy) NSString* TimeEnd;
@property (nonatomic, copy) NSNumber* Gender;
@property (nonatomic, copy) NSNumber* State;
@end
和 SBScore :
@interface SBScore : NSObject
@property (nonatomic, copy) NSNumber* Hill;
@property (nonatomic, copy) NSNumber* LVille;
@end
最后但并非最不重要的对象映射
RKObjectMapping *ScoreMapping = [RKObjectMapping mappingForClass:[SBScore class]];
[ScoreMapping addAttributeMappingsFromArray:@[@"Hill", @"LVille"]];
RKObjectMapping *GameMapping = [RKObjectMapping mappingForClass:[SBGame class]];
[GameMapping addAttributeMappingsFromDictionary:@{
@"Id" : @"Id",
@"Title" : @"Title",
@"Location" : @"Location",
@"TimeStart" : @"TimeStart",
@"TimeEnd" : @"TimeEnd",
@"Gender" : @"Gender",
@"State" : @"State",
}];
[GameMapping addPropertyMapping:[RKRelationshipMapping relationshipMappingFromKeyPath:@"score" toKeyPath:@"score" withMapping:ScoreMapping]];
RKResponseDescriptor *decp = [RKResponseDescriptor responseDescriptorWithMapping:GameMapping pathPattern:@"/Games" keyPath:nil statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];
[objectManager addResponseDescriptor:decp];
毕竟我收到的错误是
2012-12-29 16:49:19.553 Scoreboard[3004:c07] Failure with error Error Domain=org.restkit.RestKit.ErrorDomain Code=1001
"Unable to find any mappings for the given content" UserInfo=0x75c1460 {DetailedErrors=(

我对 RestKit 很陌生,我已经阅读了对象映射教程,但它仍然不起作用。任何想法都非常感谢。
