How to cancel network request with afnetworking

Question

Is there a way to cancel all network request (the request started by another method) before I do a network request with AFNetworking I tried like below but not work:

Answer 1

[[httpClient operationQueue] cancelAllOperations];

Answer 2

Both the other two answers are right. Don't Create new AFHTTPRequestOperationManager instance

        @interface OperateCustomerView () <WYPopoverControllerDelegate>{

        AFHTTPRequestOperationManager *manager;// = [AFHTTPRequestOperationManager manager];
    }
- (void)viewDidLoad {
    [super viewDidLoad];
    manager = [AFHTTPRequestOperationManager manager];

Answer 3

Don't Create new AFHTTPClient instance.

try "[self cancelAllHTTPOperationsWithMethod:@"POST" path:@"product/like"];
