大佬教程收集整理的这篇文章主要介绍了swift – 如何创建URL按下通知操作时运行?,大佬教程大佬觉得挺不错的,现在分享给大家,也给大家做个参考。
func notificationFires(){ /** URL Code: if let url = URL(String: "tel://") { UIApplication.shared.open(url,options: [:]) } **/ let call = UNNotificationAction(identifier:"call",title:"Call",options:[.foreground]) let cancel = UNNotificationAction(identifier: "cancel",title: "Cancel",options: [.destructive ]) let category = UNNotificationCategory(identifier: "category",actions: [call,cancel],intentIdentifiers: [],options: []) UNUserNotificationCenter.current().setNotificationCategories([category]) let notification = UIlocalnotification() notification.category = "category" // 2 notification.soundName = UIlocalnotificationDefaultSoundName notification.fireDate = datePicker.date // 3 if textField.text == "" { notification.alertBody = "You have a call right Now!" } else{ notification.alertBody = self.textField.text } // 4 notification.timeZone = NSTimeZone.default // 5 // 6 notification.applicationIconBadgenumber = 1 // 7 func application(application: UIApplication!,handleActionWithIdentifier identifier:string!,forlocalnotification notification:UIlocalnotification!,completionHandler: (() -> Void)!){ if (identifier == "call"){ if let url = URL(String: "tel://2162964785") { UIApplication.shared.open(url,options: [:]) } }else if (identifier == "cancel"){ } } UIApplication.shared.schedulelocalnotification(notification) func application(application: UIApplication,didReceivelocalnotification userInfo: [NSObject : AnyObject],fetchCompletionHandler completionHandler: (UIBACkgroundFetchResult) -> Void) { print("Recieved: notification") let center = UNUserNotificationCenter.current() center.removeDeliveredNotifications(withIdentifiers: ["notification"]) } }
就像是:
func userNotificationCenter(_ center: UNUserNotificationCenter,didReceive response: UNNotificationResponse,withCompletionHandler completionHandler: @escaping () -> Void) { if response.actionIdentifier == "call" { let body = response.notification.request.content.body if let url = URL(String: "tel://\(body)") { UIApplication.shared.open(url,options: [:],completionHandler: nil) } } }
主体常量将设置为您要“打开”的电话号码.
此外,重要的是要注意这必须在实际设备上进行测试.打开tel方案在模拟器中什么都不做.
UNUserNotificationCenterDelegate API参考:https://developer.apple.com/reference/usernotifications/unusernotificationcenterdelegate
编辑:
您不需要调用委托方法.相反,你实现它.委托方法由UNUserNotificationCenter调用.
为了使其正常工作,确保将uNUserNotificationCenter.current()委托属性设置为符合UNUserNotificationCenterDelegate协议的类非常重要.
例如,如果您在AppDelegate中处理通知,则可能具有以下方法:
func callNotification() { let center = UNUserNotificationCenter.center() // TODO: - Create your actions,category,content,trigger and request... center.delegate = self // Important! center.removeAllPendingNotificationrequests() center.add(request,withCompletionHandler: nil) }
上面的方法将负责定义您的通知并安排它.为简洁起见,我已经省略了所有定义通知的代码,因为您表明这是有效的.相反,您应该注意委托属性设置为self.
然后在扩展中,您将使AppDelegate符合UNUserNotificationCenterDelegate并实现所需的方法.
extension AppDelegate: UNUserNotificationCenterDelegate { func userNotificationCenter(_ center: UNUserNotificationCenter,completionHandler: nil) } } } }
现在,因为您的AppDelegate符合UNUserNotificationCenterDelegate协议并且您将self(AppDelegatE)设置为UNUserNotificationCenter的委托,所以将调用userNotification(_:didReceive:withCompletionHandler :)方法的实现.
