iOS-使用AFN设置请求超时时间并做处理

AFN设置请求超时时间

第一种：

//设置超时
    [manager.requestSerializer willChangeValueForKey:@"timeoutInterval"];
    manager.requestSerializer.timeoutInterval = 30.f;
    [manager.requestSerializer didChangeValueForKey:@"timeoutInterval"];

第二种：

NSURLSessionConfiguration *config = [NSURLSessionConfiguration defaultSessionConfiguration];
    config.timeoutIntervalForRequest = 15.0;
    AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc] initWithSessionConfiguration:config];

既然有请求超时的设置，自然也有请求超时的错误，其错误码对应如下：\-1001

这时在错误中截取错误码并进行如下处理：

[manager POST:url parameters:data progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
    //        NSLog(@"url====%@\n返回数据%@",url,responseObject);
            if (result) {
                result(responseObject);
            }
        } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
            NSLog(@"error ==%@",error);
            //请求超时
            if (error.code  == -1001) {
                //1、获取当前viewController
                UIViewController *viewController = [[CommFun singleton] getCurrentVC];
                //2、隐藏加载框
                [MBProgressHUD hideHUDForView:viewController.view animated:YES];
                //3、弹出提示：请求超时
                SHOWALERT(@"请求超时,请刷新后再试！", viewController);
            }
        }];

苹果相应的错误码如下：

        NSURLErrorUnknown = -1,
        NSURLErrorCancelled = -999,
        NSURLErrorBadURL = -1000,

    }
