第一次启动时如何防止通知许可？

Question

我有一个特殊的按钮，请求允许通知的权限，但我在点击按钮之前看到权限。有人知道如何禁用它吗？

谢谢！

Answer 1

我一直在使用中AppDelegate.swift

 alarmScheduler.setupNotificationSettings() 
    window?.tintColor = UIColor.red 

    let notificationSettings = UIUserNotificationSettings(types: .alert, categories: nil) 
    UIApplication.shared.registerUserNotificationSettings(notificationSettings) 

所以我刚刚删除它，解决了我的麻烦

试试这个想法，未经测试与控制器

呼叫UIApplicationDelegate在您的视图控制器

在按钮操作，

registerForRemoteNotification() 

func registerForRemoteNotification() { 
    if #available(iOS 10.0, *) { 
     let center = UNUserNotificationCenter.current() 
     center.delegate = self 
     center.requestAuthorization(options: [.sound, .alert, .badge]) { (granted, error) in 
      if error == nil{ 
       UIApplication.shared.registerForRemoteNotifications() 
      } 
     } 
    } 
    else { 
     UIApplication.shared.registerUserNotificationSettings(UIUserNotificationSettings(types: [.sound, .alert, .badge], categories: nil)) 
     UIApplication.shared.registerForRemoteNotifications() 
    } 
} 

并实行跟踪代表，

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) 
    { 
}
