如何从应用程序 iOS 8 启用/禁用推送通知

Question

我有一个 iOS 应用程序，我需要从我的应用程序的设置页面启用/禁用推送通知；我使用以下代码启用推送通知

[[UIApplication sharedApplication] registerForRemoteNotificationTypes:
         (UIRemoteNotificationTypeBadge |  UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];

此代码禁用推送通知

[[UIApplication sharedApplication] unregisterForRemoteNotifications];

但它不适用于 iOS 8 我在调试时收到以下消息

enabledRemoteNotificationTypes is not supported in iOS 8.0 and later

谁能给我建议一个解决方案，从应用程序打开/关闭通知中心的应用程序状态？

注册：

UIUserNotificationType userNotificationTypes = (UIUserNotificationTypeAlert |
                                                        UIUserNotificationTypeBadge |
                                                        UIUserNotificationTypeSound);

UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:userNotificationTypes categories:nil];

[[UIApplication sharedApplication] registerUserNotificationSettings:settings];
        [[UIApplication sharedApplication] registerForRemoteNotifications];

注销：

[[UIApplication sharedApplication] unregisterForRemoteNotifications];

我尝试使用下面的方法，它成功了..

#ifdef __IPHONE_8_0
  //Right, that is the point
    UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIRemoteNotificationTypeBadge
|UIRemoteNotificationTypeSound
|UIRemoteNotificationTypeAlert) categories:nil];
    [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
#else
    //register to receive notifications
    UIRemoteNotificationType myTypes = UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound;
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:myTypes];
#endif

为 iOS 8.0 添加以下方法

#ifdef __IPHONE_8_0
- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings
{
    //register to receive notifications
    [application registerForRemoteNotifications];
}

- (void)application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forRemoteNotification:(NSDictionary *)userInfo completionHandler:(void(^)())completionHandler
{
    //handle the actions
    if ([identifier isEqualToString:@"declineAction"]){
    }
    else if ([identifier isEqualToString:@"answerAction"]){
    }
}
#endif

registerForRemoteNotificationTypes 方法是 deprecated。 Apple 列出了您应该使用的新方法 (registerForRemoteNotifications)。

很难说您的问题是关于您收到的警告，还是关于它按您预期的方式运行。
