iOS8检查remotenotificationtype的权限

Question

我可以检查用户是否在iOS8之前授予了通知(警告)权限:

UIRemoteNotificationType types = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];
if (types & UIRemoteNotificationTypeAlert)
{
    //user granted
}

它不适用于iOS8,它说:

iOS (3.0 and later) Deprecated:Register for user notification settings using the  registerUserNotificationSettings: method instead.

控制台说:

enabledRemoteNotificationTypes is not supported in iOS 8.0 and later.

那么如何在iOS 8上查看呢？

好的,我这样解决了我的问题:

BOOL isgranted = false;

#if __IPHONE_OS_VERSION_MAX_ALLOWED >= 80000
    if ([[UIApplication sharedApplication] respondsToSelector:@selector(isRegisteredForRemoteNotifications)])
    {
        isgranted =  [[UIApplication sharedApplication] isRegisteredForRemoteNotifications];
    }
#else
    UIRemoteNotificationType types = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];
    if (types & UIRemoteNotificationTypeAlert)
    {
        isgranted = true;
    }
#endif
