iOS上的每日本地通知

Question

我需要製作本地通知，每天在19:30提醒用戶。

這裏是我做的：

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)") 
     } 
    }) 

然而，我發現，該通知是不警惕19:30。相反，它提前15分鐘提醒。而且，它也不能每天報警。我做錯了什麼？以下功能

使用安排您的通知：

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) 
}
