使用RestKit执行同步请求 [英] Using RestKit to perform a synchronous request

问题描述

- (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;

}

你好，我想像上面那样拨打RestKit电话同步，以便在调用成功块之后返回myResult。

Hello I would like to make a RestKit call like the above Synchronous so as to return myResult after the call of the Success block.

推荐答案

您可以使用如下方法：

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;

注意：

• 完成块在操作完成后称为 ，因此，如果您提供成功/失败块，则在 after 方法返回$ b之前不会调用它们$ b
  
  
  • （这就是为什么我建议您将 nil 传递到完成块中的原因。）
  
  
  • 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
    • (This is why I suggest you pass nil into the completion blocks.)
