Question

我使用解析sdk将当前用户频道添加到工作代码中但我想在应用示例中更改当前频道（在Viewcontroller.m中）

我的代码在这里

Appdelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.

    sleep(2);

    [Parse setApplicationId:@"sdfsdfsdfsdfsdf"
                  clientKey:@"sdfsdfsdfsdf"];

    // Register for Push Notitications
    UIUserNotificationType userNotificationTypes = (UIUserNotificationTypeAlert |
                                                    UIUserNotificationTypeBadge |
                                                    UIUserNotificationTypeSound);
    UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:userNotificationTypes
                                                                             categories:nil];
    [application registerUserNotificationSettings:settings];
    [application registerForRemoteNotifications];

    return YES;
}




- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
    // Store the deviceToken in the current installation and save it to Parse.
    PFInstallation *currentInstallation = [PFInstallation currentInstallation];
    [currentInstallation setDeviceTokenFromData:deviceToken];




    [currentInstallation saveInBackground];
}

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
    [PFPush handlePush:userInfo];
}

我的视图controller.m文件

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.


    PFInstallation *currentInstallation = [PFInstallation currentInstallation];

    currentInstallation.channels = @[@"Second"];
    [currentInstallation saveInBackground];

}

但不要将当前用户频道Frist更改为Second。我尝试了一切但不改变我需要帮助。谢谢！

您是否尝试将用户取消订阅旧频道，然后将其订阅到新频道？

这是我订阅和取消订阅频道的代码，它运行正常：

PFInstallation *currentInstallation = [PFInstallation currentInstallation];
[currentInstallation removeObject:@"type1user" forKey:@"channels"];
//subcribing to the second channel
[currentInstallation addUniqueObject:@"type2user" forKey:@"channels"];
[currentInstallation saveInBackground];

以及取消订阅和订阅第二频道：
