在 Afnetworking 2.0 中取消发布请求

Question

您好，我正在使用 AFnetworking 2.0 发出发布请求。 我的请求如下所示。

 AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
            manager.responseSerializer = [AFXMLParserResponseSerializer serializer];
            [manager.requestSerializer setValue:@"some value" forHTTPHeaderField:@"x"];

            [manager POST:url parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {

                //doing something

            } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
                // error handling.
            }];

我怎样才能取消这个请求？？？

Answer 1

POST 方法返回AFHTTPRequestOperation 操作。您可以拨打cancel取消。

AFHTTPRequestOperation *post =[manager POST:nil parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
  //doing something
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
   // error handling.
}];

//Cancel operation
[post cancel];

Answer 2

试过[manager.operationQueue cancelAllOperations]？
