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

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 code sample注册推送通知申请:

- (BOOL)applicationUIApplication *)application didFinishLaunchingWithOptionsNSDictionary*)launchOptions
{
    //-- Set Notification
    if ([application respondsToSelectorselector(isRegisteredForRemoteNotifications)]) 
    {
           // iOS 8 Notifications
           [application registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypesUIUserNotificationTypeSound | 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？

Best Answer-推荐答案

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] respondsToSelectorselector(currentUserNotificationSettings)]) {
        UIUserNotificationSettings *currentSettings = [[UIApplication sharedApplication] currentUserNotificationSettings];
        if (currentSettings.types == UIUserNotificationTypeNone) {}

最好的
