override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view,typically from a nib.
askForPermission()
}
@IBAction func addlocalnotification(_ sender: AnyObject) {
addlocalnotification()
}
func addlocalnotification() {
let content = UNMutableNotificationContent()
content.title = "iOS10.0"
content.body = "Hello Buddy"
content.sound = UNNotificationSound.default()
// Deliver the notification in five seconds.
let trigger = UNTimeIntervalNotificationTrigger.init(timeInterval: 5,repeats: false)
let request = UNNotificationRequest.init(identifier: "FiveSecond",content: content,trigger: trigger)
// Schedule the notification.
let center = UNUserNotificationCenter.current()
center.add(request) { (error) in
print(error)
}
print("should have been added")
}
func askForPermission() {
UNUserNotificationCenter.current().requestAuthorization(options: [.alert,.sound,.badge]) { (granted,error) in
}
}
解决方法
您必须实现UNUserNotificationCenter的委托,以告知系统您希望在应用程序运行时显示通知.请参见此处的示例：
