ios - 从明天开始在 Swift 中安排本地通知每天重复

Question

我正在尝试安排本地通知在特定时间每天触发（即重复），但从明天开始。

即“从明天开始，每天晚上 8 点触发通知”

我一直使用这个SO question 作为指导，我相信我正在做它所说的，但是当我运行以下代码时，我今天仍然收到通知（例如，如果我在晚上 8 点之前安排通知）：

    func testDateNotification(){

    let content = UNMutableNotificationContent()
    content.title = "Test"
    content.body = "This is a test"
    let tomorrow = Calendar.current.date(byAdding: .day, value: 1, to: Date())

    let userCalendar = Calendar.current
    var components = userCalendar.dateComponents([.hour, .minute], from: tomorrow!)

    components.hour = 20
    components.minute = 00


    let trigger = UNCalendarNotificationTrigger(dateMatching: components, repeats: true)
    let request = UNNotificationRequest(identifier: "test", content: content, trigger: trigger)

    UNUserNotificationCenter.current().add(request) { (error) in
        if ((error) != nil){
            print("Error \(String(describing: error))")
        }
    }

}

Answer 1

import UserNotifications

1. 检查用户权限

   UNUserNotificationCenter.current().requestAuthorization(options:[.badge, .alert, .sound]) {
   if $0 { } }
   

2. 添加通知

    let fromDate = Date(timeIntervalSince1970: Double(0.0))
   
    let dateComponent = Calendar.current.dateComponents([.year, .month, .day, .hour, .minute, .second], from: fromDate)
   
    let trigger = UNCalendarNotificationTrigger(dateMatching: dateComponent, repeats: true)
    print(trigger.nextTriggerDate() ?? "nil")
   
    let content = UNMutableNotificationContent()
    content.title = "title"
    content.body = "body"
    let request = UNNotificationRequest(identifier: "identify", content: content, trigger: trigger)
    UNUserNotificationCenter.current().add(request) { 
        if let error = $0 {
            print(error)
            return
        }else { 
            print("scheduled") 
        }
    }
