在Parse上删除iOS的用户推送通知

Question

您将如何使用解析将用户从接收推送通知中删除？ 例如，如果用户转到其设置（在应用程序内）并决定关闭推送通知...

我以为删除他们的“全局”频道可以解决问题，但用户似乎仍然可以使用它们。 并考虑一下，如果确实可行，他们仍然可以将推送发送到与用户关联的其他渠道。 无论如何，对此有什么解决方案？

我尝试了以下两种方法：

currentInstallation.channels = @[ @"global" ]; //enable

currentInstallation.channels = @[]; //disable

和

[currentInstallation addUniqueObject:@"global" forKey:@"channels"]; //enable

[currentInstallation removeObject:@"global" forKey:@"channels"]; //disable

然后，我尝试为“所有人”和仅与“全局”频道匹配的用户发送“通过解析” Web UI。 运气不好，用户仍然收到了它。

我几乎遵循了Parse iOS Push设置教程。 这是我的实现外观：

-(void)displayPushAuthRequest{
    UIApplication *app = [UIApplication sharedApplication];
    if([app respondsToSelector:@selector(registerUserNotificationSettings:)] && [app respondsToSelector:@selector(registerForRemoteNotifications)]){
        //ios 8
        UIUserNotificationType userNotificationTypes = (UIUserNotificationTypeAlert |
                                                        UIUserNotificationTypeBadge |
                                                        UIUserNotificationTypeSound);
        UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:userNotificationTypes
                                                                                 categories:nil];
        [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
        [[UIApplication sharedApplication] registerForRemoteNotifications];
    }
    {
        //ios 7
        UIRemoteNotificationType myTypes = UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound;
        [[UIApplication sharedApplication] registerForRemoteNotificationTypes:myTypes];

    }

}


- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
    // Save the settings locally (first time)
    [[NSUserDefaults standardUserDefaults] setBool:YES forKey:@"didRegisterForRemoteNotifications"];
    [[NSUserDefaults standardUserDefaults]synchronize];

    // Store the deviceToken in the current installation and save it to Parse.
    PFInstallation *currentInstallation = [PFInstallation currentInstallation];
    [currentInstallation setDeviceTokenFromData:deviceToken];
    currentInstallation.channels = @[ @"global" ];
    [currentInstallation saveInBackground];

}

Answer 1

你可以通过以下方法尝试

PFInstallation *currentInstallation = [PFInstallation  currentInstallation];
currentInstallation.channels = [NSArray array];
[currentInstallation saveEventually];

Answer 2

如何处理pasrse，app是appdelegate对象，uuidDT是在应用程序委托方法中存储在字符串formate中的设备令牌。

-(IBAction)notificationTapped:(UISwitch*)sender;

 {

PFInstallation *currentInstallation = [PFInstallation currentInstallation];

if (sender.isOn)
{
    if ([[UIApplication sharedApplication]respondsToSelector:@selector(isRegisteredForRemoteNotifications)])
    {
        // iOS 8 Notifications
            [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
        [[UIApplication sharedApplication] registerForRemoteNotifications];
        [currentInstallation setDeviceToken:app.uuidDT];
        [currentInstallation saveInBackground];
    }
}
else
{
    [[UIApplication sharedApplication] unregisterForRemoteNotifications];
        [currentInstallation setDeviceToken:@""];
    [currentInstallation saveInBackground];
}

}

下面将如何将设备令牌转换为字符串，请在appdelegate的didRegisterForRemoteNotificationsWithDeviceToken中输入此代码

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
    // Store the deviceToken in the current installation and save it to Parse.
    PFInstallation *currentInstallation = [PFInstallation currentInstallation];
    NSString * deviceTokenString = [[[[deviceToken description]stringByReplacingOccurrencesOfString: @"<" withString: @""]stringByReplacingOccurrencesOfString: @">" withString: @""]  stringByReplacingOccurrencesOfString: @" " withString: @""];
    self.uuidDT=deviceTokenString;

    [currentInstallation setDeviceToken:uuidDT];

    [currentInstallation saveInBackground];



}

和它的工作正常..可能这不是正确的方法。 但无论如何它的工作.....
