【问题描述】：

我正在尝试检查我的应用程序的 PushNotifications 是否已启用。

在 AppDelegate.m 中，我为远程通知注册了应用程序，并在 iPhone (ios 8) 上的设置中启用了此应用程序的推送通知。

我已经用谷歌搜索了方法：

UIRemoteNotificationType types = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];

BOOL check = [[UIApplication sharedApplication] isRegisteredForRemoteNotifications];

结果，types = UIRemoteNotificationTypeNone 和 check = NO。

我正在使用这个code sample 注册推送通知应用程序：

- (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？

【参考方案1】：

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

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

最好的

【讨论】：

谢谢它解决了我的问题。它会检测用户是否关闭通知。

【参考方案2】：

尝试使用以下代码检查您的状态：

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

编辑

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

【讨论】：

此代码进入“全部关闭”状态。显然是因为 [[UIApplication sharedApplication] enabledRemoteNotificationTypes];返回 UIRemoteNotificationTypeNone 正如我在问题中提到的那样。

如何注册远程通知。我很确定你没有得到错误的回应。您的应用根本没有正确配置推送

嗯，我假设如果 iPhone 设置菜单中的应用程序通知设置正确，则应用程序配置正确。为问题添加了注册码

必须与 iOS 8 兼容，这在 iOS8 中已被弃用
