我使用的是 iOS 10.3.2 Beta 4 和 xcode 8.3.2。我试图每天在同一时间触发通知,但是通知似乎从未触发。如果我不使用日历触发器并使用时间间隔触发器,它们会按预期工作。
这是我的代码
let content = UNMutableNotificationContent()
content.title = "Daily Notification"
content.subtitle = ""
content.body = NSLocalizedString("Hello I am a notification", comment: "Comment")
content.badge = 1
content.sound = UNNotificationSound.default()
let calendar = Calendar.current
var dateComponents = calendar.dateComponents([.day, .month, .year, .hour], from: Date())
dateComponents.hour = 14
dateComponents.minute = 55
let trigger = UNCalendarNotificationTrigger(dateMatching: dateComponents, repeats: false)
NSLog("Setting daily notification - \(dateComponents)")
let request = UNNotificationRequest(identifier: "dailyWarning", content: content, trigger: trigger)
center.add(request, withCompletionHandler: { error in
if error != nil {
NSLog("Error occurred")
} else {
NSLog("Request added successfully: %@", request)
}
})
