所以我可以像这样安排通知；
//iOS 10 Notification
if #available(iOS 10.0, *) {
var displayDate: String {
let dateFormatter = DateFormatter()
dateFormatter.dateStyle = DateFormatter.Style.full
return dateFormatter.string(from: datePicker.date as Date)
}
let notif = UNMutableNotificationContent()
notif.title = "I am a Reminder"
notif.subtitle = "\(displayDate)"
notif.body = "Here's the body of the notification"
notif.sound = UNNotificationSound.default()
notif.categoryIdentifier = "reminderNotification"
let today = NSDate()
let interval = datePicker.date.timeIntervalSince(today as Date)
let notifTrigger = UNTimeIntervalNotificationTrigger(timeInterval: interval, repeats: false)
let request = UNNotificationRequest(identifier: "reminderNotif", content: notif, trigger: notifTrigger)
UNUserNotificationCenter.current().add(request, withCompletionHandler: { error in
if error != nil {
print(error)
// completion(Success: false)
} else {
//completion(Sucess: true)
}
})
}
我已经请求了权限，appDelegate并且使用通知扩展程序在我的自定义视图中显示通知很好。
我在appDelegate通知类别中添加了通知操作；这些也会出现。
//Notifications Actions
private func configureUserNotifications() {
if #available(iOS 10.0, *) {
let tomorrowAction = UNNotificationAction(identifier: "tomorrowReminder", title: "Remind Me Tomorrow", options: [])
let dismissAction = UNNotificationAction(identifier: "dismissReminder", title: "Dismiss", options: [])
let category = UNNotificationCategory(identifier: "reminderNotification", actions: [tomorrowAction, dismissAction], intentIdentifiers: [], options: [.customDismissAction])
UNUserNotificationCenter.current().setNotificationCategories([category])
} else {
// Fallback on earlier versions
}
}
我在通知扩展.plist文件中设置了相同的类别。在通知扩展中，当用户点击某个操作时，我有以下内容可以更改文本。
//Handle Notification Actions And Update Notification Window
private func didReceive(_ response: UNNotificationResponse, completionHandler done: (UNNotificationContentExtensionResponseOption) -> Void) {
if response.actionIdentifier == "tomorrowReminder" {
print("Tomrrow Button Pressed")
subLabel.text = "Reminder For Tomorrow"
subLabel.textColor = UIColor.blue
done(.dismissAndForwardAction)
}
if response.actionIdentifier == "dismissReminder" {
print("Dismiss Button Pressed")
done(.dismiss)
} else {
print("Else response")
done(.dismissAndForwardAction)
}
}
然而，文本没有改变，也没有调用任何语句；
在 appDelegate 我有以下内容；
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey : Any]? = nil) -> Bool {
if #available(iOS 10.0, *) {
UNUserNotificationCenter.current().delegate = self
configureUserNotifications()
}
}
extension AppDelegate: UNUserNotificationCenterDelegate {
@available(iOS 10.0, *)
private func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: (UNNotificationPresentationOptions) -> Void) {
completionHandler([.alert, .sound])
}
@available(iOS 10.0, *)
private func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: () -> Void) {
print("Recieved Action For \(response.actionIdentifier)")
if response.actionIdentifier == "tomorrowReminder" {
print("Tomorrow Reminder")
//Set new reminder for tomorrow using the notification content title
completionHandler()
}
if response.actionIdentifier == "dismissReminder" {
print("Dismiss Reminder...")
completionHandler()
}
}
}
这两个函数实际上都没有在其中appDelegate任何一个中调用。我不确定更新扩展视图的问题是否与应用程序委托有关。我不这么认为，我已经关注了 Apple 的 WWDC 视频以及其他教程并查看了文档 API 并无法弄清楚；
- 为什么通知扩展文本标签没有更新？
- 为什么 appDelegate 中的函数没有被调用？
- 如何使用应用程序委托中的通知内容来执行操作？
PS：过去几周我一直在研究并试图弄清楚这一点，这似乎相当简单，我不确定我错过了什么。我知道我不是唯一一个有这些问题的人。
