如何使用RestKit（0.20）執行DELETE請求？

Question

我試圖發送一個使用RestKit的DELETE請求，但它似乎總是作爲「GET」發送。這裏是我的代碼：

RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor 
             responseDescriptorWithMapping:[self objectMapping] 
             method:RKRequestMethodDELETE 
             pathPattern:nil 
             keyPath:nil 
statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)]; 


RKObjectRequestOperation *objectRequestOperation = [[RKObjectRequestOperation alloc] initWithRequest:request responseDescriptors:@[ responseDescriptor ]]; 
[objectRequestOperation setCompletionBlockWithSuccess:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) { 

    [delegate onRequestSuccess:mappingResult.array]; 

} failure:^(RKObjectRequestOperation *operation, NSError *error) { 
    RKLogError(@"operation failed with error: %@", error); 
    [delegate onRequestError:operation message:error]; 
}]; 

[objectRequestOperation start]; 

我也試過用RKObjectManager：DeleteObject的，它不會正確地發送一個DELETE請求，但響應不被映射。

RKObjectManager *manager = [RKObjectManager managerWithBaseURL:request.url]; 
[manager addResponseDescriptor:responseDescriptor]; 
[manager deleteObject:nil path:request.urlString parameters:nil 
       success:^(RKObjectRequestOperation *operation , RKMappingResult *mappingResult) { 
        Tag *tag = mappingResult.firstObject; // this is null, does not get mapped 

       } failure:^(RKObjectRequestOperation *operation , NSError *error) { 
        RKLogError(@"Error deleting tag %@, error: %@", tagId, error); 
       }];

如果您使用RKObjectRequestOperation，你需要自己配置request。它是GET，因爲這是默認設置。

如果您使用RKObjectManager，那麼你可以使用deleteObject，而不是你自己。
