使用RestKit执行同步请求

- (BOOL)do_a_Restkit_request_and_return_a_boolean
{
     [manager postObject:nil path:@"/mypath" parameters:@{@"password":password} success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
          myResult = [mappingResult firstObject] == 5;
      } failure:^(RKObjectRequestOperation *operation, NSError *error) {
      }];

      return myResult;

}

您好，我想像上面的 Synchronous 一样进行 RestKit 调用，以便在调用 Success 块后返回 myResult。

您可以使用这样的方法：

NSMutableURLRequest *request = // create a request…
RKObjectRequestOperation *operation = [manager objectRequestOperationWithRequest:request success:nil failure:nil];
[operation start];
[operation waitUntilFinished];

BOOL myResult = NO;

if (!operation.error) {
      myResult = [operation.mappingResult firstObject] == 5;
}

return myResult;

Notes:

• The completion blocks are called after the operation is finished, so if you provide success/failure blocks, they won't be called until after the method returns
  • （这就是为什么我建议你通过nil进入完成块。）
• waitUntilFinished将阻塞您所在的任何线程，因此请确保它不是主线程。
• 如果您需要帮助创建request, see 在 RKObjectManager 类参考中创建请求对象 http://restkit.org/api/latest/Classes/RKObjectManager.html#task_Creating%20Request%20Objects.
• 同样，如果您可以重写代码以异步工作，那可能会比这个解决方案更好。
