【问题描述】：

我正在尝试安排本地通知在每天的特定时间触发，但从明天开始。

例如"从明天开始，每天下午 2 点触发通知"

这就是我设置日程功能的方式。

func scheduleNotifications(date: Date, identfier: String, after: Bool) 
    
    let content = UNMutableNotificationContent()
    content.title = "App"
    content.body = "Test."
    content.sound = .default
    content.userInfo = ["Hour": Int(hourFormatter.string(from: date)) ?? 0]
    
    let afterDay = Calendar.current.date(byAdding: .day, value: after ? 1 : 0, to: Date())

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

    components.hour = Int(hourFormatter.string(from: date)) ?? 0
    components.minute = Int(minuteFormatter.string(from: date)) ?? 0
    
    
    let trigger = UNCalendarNotificationTrigger(dateMatching: components, repeats: true)
    let request = UNNotificationRequest(identifier: identfier, content: content, trigger: trigger)
    
    UNUserNotificationCenter.current().add(request)

【参考方案1】：

此代码用于每日通知，只需在明天的计划时间调用它

func setupNotificationSettings() 

DispatchQueue.main.async 
    let content: UNMutableNotificationContent = UNMutableNotificationContent()
    
    content.title = AppName
    content.body = "APP_Body"
    content.sound = UNNotificationSound.default
    
    let trigger: UNTimeIntervalNotificationTrigger = UNTimeIntervalNotificationTrigger(timeInterval: 86400, repeats: true)
    let request: UNNotificationRequest = UNNotificationRequest(identifier: "\(AppName)_Local", content: content, trigger: trigger)
    
    let center: UNUserNotificationCenter = UNUserNotificationCenter.current()
    center.removeDeliveredNotifications(withIdentifiers: ["\(AppName)"])
    center.removeDeliveredNotifications(withIdentifiers: ["\(AppName)"])
    center.add(request)  (error) in

但我也希望它在特定时间重复，所以最好使用 UNCalendarNotificationTrigger
