如何處理IOS推送通知時，應用程序是在前臺？

Question

如何設置我的AppDelegate處理推時，應用程序是在前臺，並在迅速3個iOS 10後臺發生的通知？包括如果我收到通知時如何使手機在前臺振動。

Answer 1

這是我如何設置我的AppDelegate文件來做到這一點：

要處理推送通知，導入以下框架：

import UserNotifications 

爲了使在任何設備進口下列框架手機震動：

import AudioToolbox 

讓你的AppDelegate一個UNUserNotificationCenterDelegate：

@UIApplicationMain 
class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate { 

在你的「didFinishLaunchingWithOptions」補充一點：

UNUserNotificationCenter.current().delegate = self 
    UNUserNotificationCenter.current().requestAuthorization(options: [.badge, .sound, .alert], completionHandler: {(granted, error) in 
     if (granted) { 
      UIApplication.shared.registerForRemoteNotifications() 
     } else{ 
      print("Notification permissions not granted") 
     } 
    }) 

這將確定用戶是否此前曾表示，您的應用程序可以發送通知。如果沒有，處理它，你怎麼樣。

要訪問該設備令牌一旦註冊：

//Completed registering for notifications. Store the device token to be saved later 
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) { 

    self.deviceTokenString = deviceToken.hexString 
} 

比特產是一個擴展我添加到我的項目：

extension Data { 
    var hexString: String { 
     return map { String(format: "%02.2hhx", arguments: [$0]) }.joined() 
    } 
} 

爲了處理時會發生什麼你的應用程序收到通知在前景：

//Called when a notification is delivered to a foreground app. 
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) { 
    //Handle the notification 
    //This will get the text sent in your notification 
    let body = notification.request.content.body 

    //This works for iphone 7 and above using haptic feedback 
    let feedbackGenerator = UINotificationFeedbackGenerator() 
    feedbackGenerator.notificationOccurred(.success) 

    //This works for all devices. Choose one or the other. 
    AudioServicesPlayAlertSoundWithCompletion(SystemSoundID(kSystemSoundID_Vibrate), nil) 
} 

要處理您的應用收到

//Called when a notification is delivered to a background app. 
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping() -> Void) { 
    //Handle the notification 
    print("did receive") 
    let body = response.notification.request.content.body 
    completionHandler() 

}
