我目前正在尝试设置推送通知，尽管 xcode 认为代码中没有问题，但如果有人可以看到任何问题或对其他可能出现问题的地方提出建议，那么该功能将无法正常工作，我们将不胜感激。

func tokenRefreshNotification(notification: NSNotification){
let refreshedToken = InstanceID.instanceID().token()!
print("InstanceID token: \(refreshedToken)")
connectToFCM()

func messaging(_ messaging: Messaging, didRefreshRegistrationToken fcmToken: String) {

func connectToFCM(){

}
最佳答案
