Yangın uyarısı yalnızca bildirim göründükten sonra (swift3)

Question

Benim kodumda datePicker, datePicker değiştirildiğinde ve geçerli aygıtın geçerli tarihiyle eşleşiyor. Bir bildirim başlatır. Ancak AVSpeechUtterance Bildirimi göründüğünde datePickers zaman değiştiğinde yangınları kullanıyorum. AVSpeechUtterance ve bildirimin aynı anda kovulmasını istiyorum. APP DELEAGATE

import AVFoundation 
    import UIKit 
    import UserNotifications 

enum NotificationName: String { 
case mySpeechNotification 
} 


    @UIApplicationMain 
    class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate { 

var window: UIWindow? 

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool { 
    if #available(iOS 10.0, *) { 
     let center = UNUserNotificationCenter.current() 
     center.delegate = self 
     center.requestAuthorization(options: [.alert, .badge, .sound]) { (granted, error) in 
      if error != nil { 
       print("Ops, error trying to get authorization") 
      } else { 
       if !granted { 
        print("Dude, let me use notifications!") 
       } 
      } 
     } 
    } 
    return true 
} 

func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void)  { 
    print("Oh, will present a notification, let's see the identifier: \(notification.request.identifier)") 
    if (notification.request.identifier == NotificationName.mySpeechNotification.rawValue) { 
     print("Speaking...") 
       } else { 
     print("Nothing to say...") 
    } 

    completionHandler(.alert) 
    let begin = AVSpeechUtterance(string: " Hello ") 
    begin.voice = AVSpeechSynthesisVoice(language: "en-US") 
    begin.rate = 0.08 

    let synthesizer = AVSpeechSynthesizer() 
    synthesizer.speak(begin) 


} 

    } 

Answer 1

import UIKit 
import AVFoundation 
import UserNotifications 

class ViewController: UIViewController { 
@IBOutlet var datePicker: UIDatePicker! 

@IBAction func datePicker(_ sender: Any) { 
    let c = UNMutableNotificationContent() 
    c.title = "Lets Roll" 
    c.subtitle = "s" 
    c.body = "d" 

    let begin = AVSpeechUtterance(string: " Hello ") 

    let synthesizer = AVSpeechSynthesizer() 

    begin.voice = AVSpeechSynthesisVoice(language: "en-US") 
    begin.rate = 0.08 

    synthesizer.speak(begin) 

    let triggerDate = Calendar.current.dateComponents([.year, .month, .day, .hour, .minute], from: datePicker.date) 
    let t = UNCalendarNotificationTrigger(dateMatching: triggerDate, repeats: false) 
    let r = UNNotificationRequest(identifier: "any", content: c, trigger: t) 

    UNUserNotificationCenter.current().add(r, withCompletionHandler: nil) 
}} 

Eğer AVSpeechUtterance için preUtteranceDelay ayarı ile denediniz mi?

Answer 2

Bildirim alındığında konuşma işleminizi gerçekleştirebilirsiniz. Bunu başarmak için aşağıdakileri yapabilirsiniz:

iOS 10'un altındaysanız,numaralı telefonu UIAppplicatinoDelegate numaralı telefondan kullanabilir ve konuşma konusuna başlayabilirsiniz.

Uygulama fikri, tetiklemiş olduğunuz "konuşma bildirimi" olduğundan emin olmak için bildirimde bir değeri kontrol etmek olabilir.

iOS 10+ kullanıyorsanız UNUserNotificationCenterDelegateExamplehere'u kullanarak örnek bir uygulamaya bakabilirsiniz.

import UserNotificationsUI //framework to customize the notification 

class TestViewController: UIViewController {

     super.viewDidLoad()

    //MARK:- Date Picker Value Changed 
    func dateChanged(_ sender: UIDatePicker) { 
     let dateFormatter = DateFormatter() 
     dateFormatter.dateFormat = "MMM dd, yyyy" 
     let selectedDate = dateFormatter.string(from: datePicker.date) 
     let currentDate = dateFormatter.string(from: Date()) 
     if selectedDate == currentDate{ 
      self.triggerLocalNotification() 
     } 
     print(selectedDate) 

    } 

    //MARK:- Removed all pending notifications

     let request = UNNotificationRequest(identifier: appDelegate.requestIdentifier, content: content, trigger: trigger) 

     UNUserNotificationCenter.current().add(request){(error) in
