AFNetworking超时无效

Question

我正在使用AFNetworking V2.5.4。

AFN的默认超时为60秒，这对我的应用来说太长了。我想把它设置为20秒。 所以我尝试按照代码manager.requestSerializer.timeoutInterval = 20; 但它不起作用。我搜索了一些帖子，说我需要添加[manager.requestSerializer willChangeValueForKey:@"timeoutInterval"]; manager.requestSerializer.timeoutInterval = 3; [manager.requestSerializer didChangeValueForKey:@"timeoutInterval"];

但是，它还没有用。

关注是我的代码

+ (AFHTTPRequestOperation *)sendRequestWithRequest:(NSMutableURLRequest*) request
                                       manager:(AFHTTPRequestOperationManager *)manager
                                       success:(void (^)(AFHTTPRequestOperation *operation, id responseObject))success
                                       failure:(void (^)(AFHTTPRequestOperation *operation, NSError *error))failure{
[manager.requestSerializer willChangeValueForKey:@"timeoutInterval"];
manager.requestSerializer.timeoutInterval = 3;
[manager.requestSerializer didChangeValueForKey:@"timeoutInterval"];
NSLog(@"manager %@, start time %lf",manager, [[NSDate date] timeIntervalSince1970]);
AFHTTPRequestOperation *operation = [manager HTTPRequestOperationWithRequest:request
                                                                     success:^(AFHTTPRequestOperation *operation,  id responseObject) {
                                                                         if (operation.response.statusCode) {
                                                                             success(operation, responseObject);
                                                                         }else{
                                                                             failure(operation, nil);
                                                                         }
                                                                     }
                                                                     failure:^(AFHTTPRequestOperation *operation,  NSError *error) {
                                                                            failure(operation, error);
                                                                     }];

[manager.operationQueue addOperation:operation];
return operation;}
