AFHTTPRequestOperation을 사용할 때 작업 간의 종속성 만들기

Question

mac 응용 프로그램에서 AFNetworking (2.4.1)을 사용하고 있습니다. 모든 다른 작업 (AFHTTPRequestOperation) 완료 후 내 자신의 블록 작업을 추가하고 싶습니다. completionOperation과 다른 것들 사이에 의존성을 추가하려고 시도했지만, completionOperation 블록은 다른 것들이 성공 또는 실패로 완료되기 전에 여전히 실행됩니다.

기본 사항을 보여주는 코드의 축소 버전이 아래에 나와 있습니다. 누구든지이 작품을 만드는 방법을 제안 할 수 있습니까? 감사.

AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] init]; 

    NSBlockOperation *completionOperation = [NSBlockOperation blockOperationWithBlock:^{ 
     NSLog(@"All operations complete"); 
     }]; 


    NSMutableURLRequest *request1 = [[AFHTTPRequestSerializer serializer] requestWithMethod:@"GET" URLString:[[NSURL URLWithString:@"https://api.parse.com/1/classes/SomeClass"] absoluteString] parameters:nil error:nil]; 
    AFHTTPRequestOperation *operation1 = [manager HTTPRequestOperationWithRequest:request1 success: 
    ^(AFHTTPRequestOperation *operation, id responseObject) 
    { 
      NSLog(@"operation 1 success"); 
    } 
    failure:^(AFHTTPRequestOperation *operation, NSError *error) 
    { 
      NSLog(@"operation 1 failure"); 
    }]; 

    NSMutableURLRequest *request2 = [[AFHTTPRequestSerializer serializer] requestWithMethod:@"GET" URLString:[[NSURL URLWithString:@"https://api.parse.com/1/classes/OtherClass"] absoluteString] parameters:nil error:nil]; 
    AFHTTPRequestOperation *operation2 = [manager HTTPRequestOperationWithRequest:request2 success: 
    ^(AFHTTPRequestOperation *operation, id responseObject) 
    { 
      NSLog(@"operation 2 success"); 
    } 
    failure:^(AFHTTPRequestOperation *operation, NSError *error) 
    { 
      NSLog(@"operation 2 failure"); 
    }]; 

    [completionOperation addDependency:operation1]; 
    [completionOperation addDependency:operation2]; 

    [manager.operationQueue addOperation:operation1]; 
    [manager.operationQueue addOperation:operation2]; 
    [manager.operationQueue addOperation:completionOperation];

- (void) test3:(void (^)(AFHTTPRequestOperation *operation, id responseObject))success 
        failure:(void (^)(AFHTTPRequestOperation *operation, NSError *error))failure 

{ 

    // block 1 
    NSString *string = [NSString stringWithFormat:@"%@weather.php?format=json", BaseURLString]; 
    NSURL *urll = [NSURL URLWithString:string]; 
    NSURLRequest *request = [NSURLRequest requestWithURL:urll]; 
    AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request]; 
    operation.responseSerializer = [AFJSONResponseSerializer serializer]; 

    [operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) { 
     NSLog(@"OPERATION 1 %@",responseObject); 
     test_Sync = @"done"; 
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) { 
     test_Sync = @"faile"; }]; 

    //block 2 
    NSString *string2 = [NSString stringWithFormat:@"%@weather.php?format=json", BaseURLString]; 
    NSURL *urll2 = [NSURL URLWithString:string2]; 
    NSURLRequest *request2 = [NSURLRequest requestWithURL:urll2]; 

    AFHTTPRequestOperation *operation2 = [[AFHTTPRequestOperation alloc] initWithRequest:request2]; 

    [operation2 setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation2, id responseObject) { 
     // Print the response body in text 
     NSLog(@"Response: OPERATION 2 %@", [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding]); 
    } failure:^(AFHTTPRequestOperation *operation2, NSError *error) { 
     NSLog(@"Error: %@", error); 
    }]; 

    // Add the operation to a queue 
    // It will start once added 
    NSOperationQueue *operationQueue = [[NSOperationQueue alloc] init]; 
    // Make operation2 depend on operation1 
    [operation addDependency:operation2]; 
    [operationQueue addOperations:@[operation, operation2] waitUntilFinished:YES];
