[英]Daily local notification on iOS
我需要发出本地通知,每天19:30提醒用户。
这是我所做的:
var dateComponents = DateComponents()
dateComponents.hour = 19
dateComponents.minute = 30
let trigger = UNCalendarNotificationTrigger(dateMatching: dateComponents, repeats: true)
let identifier = "daily.alarm"
let request = UNNotificationRequest(identifier: identifier, content: content, trigger: trigger)
UNUserNotificationCenter.current().removeAllPendingNotificationRequests()
UNUserNotificationCenter.current().add(request, withCompletionHandler: { (error) in
if error != nil {
debugPrint("center.add(request, withCompletionHandler: { (error)")
}
})
但是,我发现通知在19:30时没有发出警报。 相反,它会提前15分钟发出警报。 此外,它也无法每天发出警报。 我做错了什么?
使用以下功能安排您的通知:
func registerLocal() {
let center = UNUserNotificationCenter.current()
center.requestAuthorization(options: [.alert, .badge, .sound]) { (granted, error) in
if granted {
print("Yas!")
} else {
print("Ohhh No!!")
}
}
}
func scheduleLocal() {
let center = UNUserNotificationCenter.current()
let content = UNMutableNotificationContent()
content.title = "Drink Milk"
content.body = "Two Servings A Day Keeps Bone Problems At Bay."
content.categoryIdentifier = "alarm"
content.userInfo = ["customData": "whater"]
content.sound = UNNotificationSound.default()
var dateComponents = DateComponents()
dateComponents.hour = 19
dateComponents.minute = 30
let trigger = UNCalendarNotificationTrigger(dateMatching: dateComponents, repeats: true)
let request = UNNotificationRequest(identifier: UUID().uuidString, content: content, trigger: trigger)
center.add(request)
}
