如何触发NSOperationQueue并获得多个操作块的结果

我已经问过与NSOperationQueue有关的问题，但是我仍然在用multiples操作实现操作队列。 我有以下代码

  NSMutableArray * operationArray = [[NSMutableArray alloc] init]; for (int i =0; i<[documentModelList count]; i++) { DocumentModel * documentModel = [documentModelList objectAtIndex:i]; NSString *url = [NSString stringWithFormat:@"%@%@/%li", SERVER_URL, DOCUMENTS_DELETE,(long)documentModel.documentID]; [operationArray addObject:[AppHttpClient getDeleteRequest:nil urlQuery:url]]; } NSOperationQueue *operationQueue = [[NSOperationQueue alloc] init]; // Set the max number of concurrent operations (threads) [operationQueue setMaxConcurrentOperationCount:operationArray.count]; [operationQueue addOperations:operationArray waitUntilFinished:NO]; + (AFHTTPRequestOperation *) getDeleteRequest:(NSDictionary *)headerParams urlQuery: (NSString*)action { NSString *jsonString = @""; NSString *authorizationValue = [self setAuthorizationValue:action]; NSString *language = @"en_US"; NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init]; [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"]; [request setValue:@"application/json" forHTTPHeaderField:@"Accept"]; [request setValue:language forHTTPHeaderField:@"Accept-Language"]; [request setValue:authorizationValue forHTTPHeaderField:@"authorization"]; [request setURL:[NSURL URLWithString:action]]; [request setTimeoutInterval:500.0]; [request setHTTPMethod:@"DELETE"]; NSMutableData *postBody = [NSMutableData data]; [postBody appendData:[jsonString dataUsingEncoding:NSUTF8StringEncoding]]; [request setHTTPBody:postBody]; AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc]initWithRequest:request]; operation.responseSerializer = [AFJSONResponseSerializer serializer]; return operation; } 

上面的代码在循环中创build操作并将其添加到operationArray ，然后将此操作数组添加到operationQueue 。 现在我想触发这个并获得整个数组的响应。

}

对于整体状态，您可以创build另一个操作，该操作可以是块操作，并使用addDependency:以确保在所有其他操作完成后运行。 在创build每个删除操作的循环中添加依赖项。

对于每个单独的状态，您需要使用setCompletionBlockWithSuccess:failure:获取有关结果的反馈。
