本文介绍了UNUserNotificationCenter确实收到了从未被称为iOS10，Swift 2.3的完成处理程序的响应的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在安排iOS10中的新通知，例如:
I am scheduling new notifications in iOS10, like this:
func scheduleNotification (event : Meeting, todaysBadgeCounter: Int) {
if #available(iOS 10.0, *) {
let minutesBefore = 10
//interval in seconds from current point in time to notification
let interval : NSTimeInterval = NSTimeInterval(secondsFromNowTo(event.startTime.dateByAddingTimeInterval(-minutesBefore * 60)))
//only schedule in the future
if(interval > 0){
let category = NotificationsController.notificationCategory
let center = NotificationsController.notificationCenter
center.setNotificationCategories([category])
let content = UNMutableNotificationContent()
content.title = NSString.localizedUserNotificationStringForKey(event.title, arguments: nil)
if(minutesBefore <= 1){
content.body = NSString.localizedUserNotificationStringForKey("IOS10: Your \(event.title) is about to start", arguments: nil)
}else{
content.body = NSString.localizedUserNotificationStringForKey("IOS10: You have \(event.title) in \(Int(minutesBefore)) minutes", arguments: nil)
}
content.sound = UNNotificationSound.defaultSound()
let trigger = UNTimeIntervalNotificationTrigger.init(timeInterval: interval, repeats: false)
let identifier = NSString.localizedUserNotificationStringForKey("sampleRequest\(event.UUID)", arguments: nil)
let request = UNNotificationRequest.init(identifier: identifier, content: content, trigger: trigger)
//setting the delegate
center.delegate = self
center.addNotificationRequest(request, withCompletionHandler: { (error) in
// handle the error if needed
log.error(error?.localizedDescription)
print("SCHEDULING >=iOS10:", event.title, ", interval:", interval)
})
}
//return category
@available(iOS 10.0, *)
class var notificationCategory : UNNotificationCategory {
struct Static {
static let callNow = UNNotificationAction(identifier: NotificationActions.callNow.rawValue, title: "Call now", options: [])
static let clear = UNNotificationAction(identifier: NotificationActions.clear.rawValue, title: "Clear", options: [])
static let category : UNNotificationCategory = UNNotificationCategory.init(identifier: "CALLINNOTIFICATION", actions: [callNow, clear], intentIdentifiers: [], options: [])
}
return Static.category
}
我能够安排通知，并在适当的时间接收本地通知.但是:我从未按照本教程使用的委托方法永远不会执行，但是每次我点击通知时都会执行didReceiveLocalNotification:
I am able to schedule notifications, and receive local notifications at the right time. BUT: my delegate methods that I used according to the tutorial are never executed, however the didReceiveLocalNotification is executed each time I tap on the notification:
extension NotificationsController: UNUserNotificationCenterDelegate {
@available(iOS 10.0, *)
func userNotificationCenter(center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: () -> Void) {
print("IOS10 delivered")
// Response has actionIdentifier, userText, Notification (which has Request, which has Trigger and Content)
switch response.actionIdentifier {
case NotificationActions.NotifyBefore.rawValue:
print("notify")
break
case NotificationActions.callNow.rawValue:
print("callNow")
break
case NotificationActions.clear.rawValue:
print("clear")
default: break
}
}
@available(iOS 10.0, *)
func userNotificationCenter(center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: (UNNotificationPresentationOptions) -> Void) {
// Delivers a notification to an app running in the foreground.
print("IOS10 delivered 2222")
}
}
ReceiveLocalNotification是否不被弃用?如何使这些方法被调用?
Wasn't didReceiveLocalNotification deprecated? How to make these methods to be called?
更新:
我从这里更新了代码，并提出了一些建议:
I updated my code with some suggestions from here, namely:
- 我将UNUserNotificationCenter.delegate的分配添加到applicationDidFinishLaunchingWithOptions.
- 我还尝试将这些方法(委托方法)从扩展名移至NotificationsController.swift类，并将此类设置为UNUserNotificationCenterDelegate.也不适合我.
推荐答案
请求标识符不是通知类别.
Request identifier is not the notification category.
只需添加以下行:
content.categoryIdentifier = identifier
更新:刚做了一个简单的应用程序.一切似乎都正常:
Update: Just made a simple app. Everything seems to working fine:
class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
UNUserNotificationCenter.current().delegate = self
UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .badge, .sound]) { (granted, error) in
if granted {
self.registerCategory()
self.scheduleNotification(event: "test", interval: 3)
self.scheduleNotification(event: "test2", interval: 5)
}
}
return true
}
func registerCategory() -> Void{
let callNow = UNNotificationAction(identifier: "call", title: "Call now", options: [])
let clear = UNNotificationAction(identifier: "clear", title: "Clear", options: [])
let category : UNNotificationCategory = UNNotificationCategory.init(identifier: "CALLINNOTIFICATION", actions: [callNow, clear], intentIdentifiers: [], options: [])
let center = UNUserNotificationCenter.current()
center.setNotificationCategories([category])
}
func scheduleNotification (event : String, interval: TimeInterval) {
let content = UNMutableNotificationContent()
content.title = event
content.body = "body"
content.categoryIdentifier = "CALLINNOTIFICATION"
let trigger = UNTimeIntervalNotificationTrigger.init(timeInterval: interval, repeats: false)
let identifier = "id_"+event
let request = UNNotificationRequest.init(identifier: identifier, content: content, trigger: trigger)
let center = UNUserNotificationCenter.current()
center.add(request, withCompletionHandler: { (error) in
})
}
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
print("didReceive")
completionHandler()
}
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
print("willPresent")
completionHandler([.badge, .alert, .sound])
}
}
更新2:在Swift 2.3中重写
Update 2: Rewritten in Swift 2.3
class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate {
var window: UIWindow?
func applicationDidFinishLaunching(application: UIApplication) {
UNUserNotificationCenter.currentNotificationCenter().delegate = self
UNUserNotificationCenter.currentNotificationCenter().requestAuthorizationWithOptions([.Badge, .Sound, .Alert]) { (granted, error) in
if granted {
self.registerCategory()
self.scheduleNotification("test", interval: 3)
self.scheduleNotification("test2", interval: 5)
}
}
}
func registerCategory() -> Void{
let callNow = UNNotificationAction(identifier: "call", title: "Call now", options: [])
let clear = UNNotificationAction(identifier: "clear", title: "Clear", options: [])
let category : UNNotificationCategory = UNNotificationCategory.init(identifier: "CALLINNOTIFICATION", actions: [callNow, clear], intentIdentifiers: [], options: [])
let center = UNUserNotificationCenter.currentNotificationCenter()
center.setNotificationCategories([category])
}
func scheduleNotification(event : String, interval: NSTimeInterval) {
let content = UNMutableNotificationContent()
content.title = event
content.body = "body"
content.categoryIdentifier = "CALLINNOTIFICATION"
let trigger = UNTimeIntervalNotificationTrigger.init(timeInterval: interval, repeats: false)
let identifier = "id_"+event
let request = UNNotificationRequest.init(identifier: identifier, content: content, trigger: trigger)
let center = UNUserNotificationCenter.currentNotificationCenter()
center.addNotificationRequest(request) { (error) in
}
}
func userNotificationCenter(center: UNUserNotificationCenter, willPresentNotification notification: UNNotification, withCompletionHandler completionHandler: (UNNotificationPresentationOptions) -> Void) {
print("willPresent")
completionHandler([.Badge, .Alert, .Sound])
}
func userNotificationCenter(center: UNUserNotificationCenter, didReceiveNotificationResponse response: UNNotificationResponse, withCompletionHandler completionHandler: () -> Void) {
print("didReceive")
completionHandler()
}
}
