我在应用程序中使用本地通知时遇到问题。
我正在安排带有自定义内容和自定义操作类别的本地通知。它在 iOS 11 中进行调度和触发，但在 iOS 10 中则不然。
根据文档，它应该也可以在 iOS 10 中运行。
为什么我的代码在这种特定情况下不起作用？
代码如下：
AppDelegate.swift
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
.......
if #available(iOS 10.0, *) {
UNUserNotificationCenter.current().delegate = self
}
.......
return true
}
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
completionHandler([.alert, .sound, .badge])
}
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
print("Local Notification :: ", response)
}
自定义操作代码
func configureNotificationCenter() {
let actionRemindAgain = UNNotificationAction(identifier: NTConstants.LocalNotification.action.remindMeAgain, title: "Remind me Again!⏰", options: [.authenticationRequired])
let actionViewDetails = UNNotificationAction(identifier: NTConstants.LocalNotification.action.viewDetails, title: "View Details!", options: [.foreground])
let actionClose = UNNotificationAction(identifier: NTConstants.LocalNotification.action.dismiss, title: "Dismiss", options: [])
//Event Category
let eventCategory = UNNotificationCategory(identifier: NTConstants.LocalNotification.category.reminder, actions: [actionRemindAgain, actionViewDetails, actionClose], intentIdentifiers: [], options: [])
//Register Category
UNUserNotificationCenter.current().setNotificationCategories([eventCategory])
}
时间表代码
func scheduleLocalNotification() {
self.configureNotificationCenter()
//Local Notification
let content = UNMutableNotificationContent()
content.title = notifyTitle
content.subtitle = notifySubTitle
content.body = notifyDesc
//Category
content.categoryIdentifier = "reminder"
//Trigger
let scheduleDate = Date(timeIntervalSince1970: TimeInterval(scheduleTimeInterval / 1000)) //My Schedule Data
let triggerDate = Calendar.current.date(byAdding: .hour, value: -2, to: scheduleDate) // Should be call before 2 hours
let dateComponents = Calendar.current.dateComponents([.year, .month, .day, .hour, .minute], from: triggerDate!)
let trigger = UNCalendarNotificationTrigger(dateMatching: dateComponents, repeats: false)
//Request
let request = UNNotificationRequest(identifier: "notification_\((notifyId))", content: content, trigger: trigger)
//Add Request
UNUserNotificationCenter.current().add(request) { (error) in
if let error = error {
NTPrint("Unable to add notification : \(error.localizedDescription)")
}
else {
NTPrint("Scheduled :: ", request.identifier)
}
}
}
此代码成功运行并安排本地通知。结果如下：
<UNNotificationRequest: 0x18d65360;
identifier: notification_111,
content: <UNNotificationContent: 0x18daead0;
title: Event..!!,

中午 12 点设置正确，因为我在 2 小时前设置。它在 iOS 11 设备上运行良好。但在 iOS 10 中不起作用。更新后的代码有什么问题吗？或者还有什么需要处理的吗？
