我目前正在尝试让 RestKit 0.20 与我当前的项目一起运行,但我遇到了一些困难。
我尝试将我的请求映射到一个对象,它显然是映射,但结果只返回空对象。
愿你们知道该怎么做。
这是代码
// Create object mapping for MVMyCar
RKObjectMapping *mapping = [RKObjectMapping mappingForClass:[MVMyCar class]];
[mapping addAttributeMappingsFromDictionary:@{
@"my_car_id" : @"uuid"
}];
// ResponseDescriptor
RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:mapping
method:RKRequestMethodGET
pathPattern:kAPIPathGarage
keyPath:@"result"
statusCodes:[NSIndexSet indexSetWithIndex:200]];
[[RKObjectManager sharedManager] addResponseDescriptor:responseDescriptor];
[RKObjectManager.sharedManager getObjectsAtPath:kAPIPathGarage parameters:nil success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
NSLog(@"Mapping: %@",[mappingResult array]);
} failure:^(RKObjectRequestOperation *operation, NSError *error) {
}];
这是 restkit 跟踪:
2013-07-18 18:32:01.566 [12722:3a07] T restkit.object_mapping:RKMappingOperation.m:953 Performing mapping operation: <RKMappingOperation 0xc2920b0> for 'MVMyCar' object. Mapping values from object {
"my_car_id" = 76;
} to object *nil description* with object mapping (null)

2013-07-18 18:32:01.573 [12722:3a07] T restkit.object_mapping:RKMappingOperation.m:572 Mapped attribute value from keyPath 'my_car_id' to 'uuid'. Value: 76
2013-07-18 18:32:01.574 [12722:3a07] D restkit.object_mapping:RKMappingOperation.m:1021 Finished mapping operation successfully...
这就是结果,实际上在数量上是正确的:13 个元素。
2013-07-18 18:32:01.575 [12722:3a07] D restkit.object_mapping:RKMapperOperation.m:403 Finished performing object mapping. Results: {
result = (

(null),
(null),

);
}
非常感谢!
