swift – 如何创建URL按下通知操作时运行？
|
我创建了一个包含两个操作的通知.我的一个动作叫做“取消”,而另一个叫做“呼叫”.如何使“调用”操作运行我添加到代码中的注释中的URL.这是我的代码：
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"])
}
}
解决方法
假设您的通知正常,您可以符合UNUserNotificationCenterDelegate来处理“调用”操作.
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. （编辑：李大同） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
