ios - 在 Xcode 8 中未调用 didRegisterForRemoteNotificationsWithDeviceToken

Question

我使用 iOS 10 SDK 在 Xcode 8 上构建我的应用程序。didRegisterForRemoteNotificationsWithDeviceToken 不会为 iOS 9.3 设备调用，因此 iOS 9.3 和以下设备无法接收推送通知。但 iOS 10 设备可以接收推送。如果我使用 iOS 9.3 SDK 在 Xcode 7.3 上构建相同的应用程序，则 iOS 9 设备可以接收推送。所以，我确信我的所有设置都应该是正确的。

这是我的实现:

// Push notification
if( SYSTEM_VERSION_LESS_THAN( @"10.0" ) )
{
    if([application respondsToSelector:@selector(registerUserNotificationSettings:)])
    {
        UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound) categories:nil];
        [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
        [[UIApplication sharedApplication] registerForRemoteNotifications];

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


}
else
{
    UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
    center.delegate = self;
    [center requestAuthorizationWithOptions:(UNAuthorizationOptionSound | UNAuthorizationOptionAlert | UNAuthorizationOptionBadge) completionHandler:^(BOOL granted, NSError * _Nullable error)
     {
         if( !error )
         {
             [[UIApplication sharedApplication] registerForRemoteNotifications];
         }

     }];
}


- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {

NSString * tokenAsString = [[[deviceToken description]
                             stringByTrimmingCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"<>"]]
                            stringByReplacingOccurrencesOfString:@" " withString:@""];

}



- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error {

DLog(@"app didFailToRegisterForRemoteNotificationsWithError: %@", error.description);
}

为什么要使用已弃用的方法？？ [[UIApplication sharedApplication] registerForRemoteNotificationTypes:

当我删除它时

[[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge)categories:nil]];

和使用

[[UIApplication sharedApplication] registerForRemoteNotifications];

我从 APNs 获得了 token 。
