没有可见@interface为'AFHTTPSessionManager'声明选择'POST：参数：进展：成功：失败：'

Question

我是新来的目标c和IOS，我试图发布一些值到一个URL，并试图获得响应。

，而是因为，我遇到这个错误

/用户/桌面/ MyIOSApps /聊天系统，我不能编译我的项目/聊天系统/ SignInVC.m：92：14：无 可见@interface为 'AFHTTPSessionManager' 宣布选择 'POST：参数：进展：成功：失败：'

Objective-C代码

- (void)submitLoginRequest:(NSString *)email password:(NSString *)password { 

    AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]]; 
    manager.requestSerializer = [AFJSONRequestSerializer serializer]; 

    NSMutableDictionary *dict = [[NSMutableDictionary alloc] init]; 
    [dict setValue:email forKey:@"Email"]; 
    [dict setValue:password forKey:@"Password"]; 

    NSLog(@"Login dicxtionary : %@", dict); 
    MBProgressHUD *hud; 
    hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES]; 
    hud.label.text = @"Please wait. Logging in..."; 

    [hud showAnimated:YES]; 


    // send user login data to hosting via AFHTTP Async Request in AFNetworking 
    [manager POST:BASEURL parameters:dict progress:nil success:^(NSURLSessionTask *task, id responseObject) { 

     [hud hideAnimated:YES]; 
     // Login response validation 
     if (responseObject == [NSNull null]) { 
      [self showMessage:@"Login Failed" Message:@"Unable to login. Please try again!"]; 
     }else { 
      //NSError *error = nil; 
      NSLog(@"response type : %@", NSStringFromClass([responseObject class])); 
      //NSDictionary *response = [NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingMutableContainers error:&error]; 
      [self checkResultValue:(NSDictionary *)responseObject]; 
     } 

    } failure:^(NSURLSessionTask *task, NSError *error) { 

     NSLog(@"AFHTTPSession Failure : %@", [error localizedDescription]); 
    }]; 

} 

有人可以帮我解决这个问题。 TNX。

您正在查找的方法是POST:parameters:success:failure:。因此，只需从方法调用中删除progress:nil即可。整个方法调用如下所示。

[manager POST:BASEURL parameters:dict success:^(NSURLSessionTask *task, id responseObject) { 

     [hud hideAnimated:YES]; 
     // Login response validation 
     if (responseObject == [NSNull null]) { 
      [self showMessage:@"Login Failed" Message:@"Unable to login. Please try again!"]; 
     }else { 
      //NSError *error = nil; 
      NSLog(@"response type : %@", NSStringFromClass([responseObject class])); 
      //NSDictionary *response = [NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingMutableContainers error:&error]; 
      [self checkResultValue:(NSDictionary *)responseObject]; 
     } 

    } failure:^(NSURLSessionTask *task, NSError *error) { 

     NSLog(@"AFHTTPSession Failure : %@", [error localizedDescription]); 
    }];
