安排 iOS 本地推送通知

Question

let center = UNUserNotificationCenter.current()
let options: UNAuthorizationOptions = [.alert, .sound];
center.requestAuthorization(options: options) { (granted, error) in
    if !granted {
        print("Something went wrong")
    }
}
center.getNotificationSettings { (settings) in
    if settings.authorizationStatus != .authorized {
        // Notifications not allowed
    }
}
let content = UNMutableNotificationContent()
content.title = "Good Morning"
content.body = "wake up"
content.sound = UNNotificationSound.default()
var dateInfo = DateComponents()
dateInfo.hour = 7
dateInfo.minute = 0
let trigger = UNCalendarNotificationTrigger(dateMatching: dateInfo, repeats: true)
let identifier = "localNotification"
let request = UNNotificationRequest(identifier: identifier, content: content, trigger: trigger)
center.add(request, withCompletionHandler: { (error) in
    if let _ = error {
        LOGG("Something went wrong")
    }
})

以上代码，在早上 7 点完美触发推送通知。我如何使用相同的代码在晚上 9 点或 12 点设置通知。谢谢

尝试在晚上 9 点开火

    var dateInfo = DateComponents()
    dateInfo.hour = 21
    dateInfo.minute = 0
