第二个视图中的SwiftUI提示通知权限

import UserNotifications

UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound, .badge]) { granted, error in
    if granted {
        // 用户授予了通知权限
    } else {
        // 用户拒绝了通知权限
    }
}

let category = UNNotificationCategory(identifier: "myCategory", actions: [], intentIdentifiers: [], options: [])

UNUserNotificationCenter.current().setNotificationCategories([category])

extension AppDelegate: UNUserNotificationCenterDelegate {
    func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
        // 处理通知的点击行为
        completionHandler()
    }
    
    func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
        // 处理在前台收到通知的行为
        completionHandler([.alert, .sound])
    }
}

UNUserNotificationCenter.current().delegate = AppDelegate()
