Question

我正在尝试检查我的应用的PushNotifications是否已启用。

在AppDelegate.m中，我注册了远程通知应用程序，并且在iPhone上的设置（iOS 8）中启用了此应用程序的推送通知。

我已经搜索了方法：

UIRemoteNotificationType types = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];

BOOL check = [[UIApplication sharedApplication] isRegisteredForRemoteNotifications];

结果， types = UIRemoteNotificationTypeNone and check = NO 。

我使用此code sample注册推送通知申请：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions
{
    //-- Set Notification
    if ([application respondsToSelector:@selector(isRegisteredForRemoteNotifications)]) 
    {
           // iOS 8 Notifications
           [application registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];

           [application registerForRemoteNotifications];
    }
    else
    {
          // iOS < 8 Notifications
          [application registerForRemoteNotificationTypes:
                     (UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound)];
    }

     //--- your custom code
     return YES;
}

这里有什么问题？

Answer 1

我认为您已经找到了解决方案，但以防万一：在iOS 8中，不推荐使用enabledRemoteNoficationTypes，您应该使用：

if ([[UIApplication sharedApplication] respondsToSelector:@selector(currentUserNotificationSettings)]) {
        UIUserNotificationSettings *currentSettings = [[UIApplication sharedApplication] currentUserNotificationSettings];
        if (currentSettings.types == UIUserNotificationTypeNone) {}

最佳

尝试使用以下代码检查您的州：

UIRemoteNotificationType allOnType = UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeBadge ;
UIRemoteNotificationType offType = UIRemoteNotificationTypeNone ;

UIRemoteNotificationType currentTypes = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];

if (currentTypes == allOnType) {
    // all are on
} else if (currentTypes == offType) {
    // all are off
} else {
    // some are on, some are off
}

修改

另外，尝试实现推送通知回调：

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken { NSLog(@"Token%@",deviceToken); } - (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)err { NSLog(@"err:%@",err); } -(void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings { //for iOS8 }

IOS 8推送通知检查返回错误的UIRemoteNotificationType
