iOS如何按天、周和小时Swift创建计划本地通知

import UserNotifications

func scheduleDailyNotification() {
    let content = UNMutableNotificationContent()
    content.title = "提醒"
    content.body = "这是每天的通知"
    content.sound = UNNotificationSound.default
    
    var dateComponents = DateComponents()
    dateComponents.hour = 8
    dateComponents.minute = 0
    
    let trigger = UNCalendarNotificationTrigger(dateMatching: dateComponents, repeats: true)
    
    let request = UNNotificationRequest(identifier: "dailyNotification", content: content, trigger: trigger)
    
    UNUserNotificationCenter.current().add(request) { (error) in
        if let error = error {
            print("创建通知失败：\(error.localizedDescription)")
        }
    }
}

import UserNotifications

func scheduleWeeklyNotification() {
    let content = UNMutableNotificationContent()
    content.title = "提醒"
    content.body = "这是每周的通知"
    content.sound = UNNotificationSound.default
    
    var dateComponents = DateComponents()
    dateComponents.weekday = 4 // 周四
    dateComponents.hour = 10
    dateComponents.minute = 0
    
    let trigger = UNCalendarNotificationTrigger(dateMatching: dateComponents, repeats: true)
    
    let request = UNNotificationRequest(identifier: "weeklyNotification", content: content, trigger: trigger)
    
    UNUserNotificationCenter.current().add(request) { (error) in
        if let error = error {
            print("创建通知失败：\(error.localizedDescription)")
        }
    }
}

import UserNotifications

func scheduleHourlyNotification() {
    let content = UNMutableNotificationContent()
    content.title = "提醒"
    content.body = "这是每小时的通知"
    content.sound = UNNotificationSound.default
    
    let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 3600, repeats: true)
    
    let request = UNNotificationRequest(identifier: "hourlyNotification", content: content, trigger: trigger)
    
    UNUserNotificationCenter.current().add(request) { (error) in
        if let error = error {
            print("创建通知失败：\(error.localizedDescription)")
        }
    }
