脱机时的本地通知(Swift)

import UserNotifications

// 请求用户授权通知权限
UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound, .badge]) { (granted, error) in
    if granted {
        // 用户授权成功
    } else {
        // 用户拒绝授权或授权失败
    }
}

// 创建本地通知内容
let content = UNMutableNotificationContent()
content.title = "提醒标题"
content.body = "提醒内容"
content.sound = UNNotificationSound.default

// 创建触发器，设置通知触发时间
let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 60, repeats: false)

// 创建通知请求
let request = UNNotificationRequest(identifier: "localNotification", content: content, trigger: trigger)

// 将通知请求添加到通知中心
UNUserNotificationCenter.current().add(request) { (error) in
    if let error = error {
        print("添加本地通知失败：\(error.localizedDescription)")
    } else {
        print("添加本地通知成功")
    }
}
