是否在前台禁用特定视图控制器的推送通知？

import UserNotifications

class YourViewController: UIViewController, UNUserNotificationCenterDelegate {
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 设置UNUserNotificationCenter的delegate为当前视图控制器
        UNUserNotificationCenter.current().delegate = self
    }
    
    // 实现UNUserNotificationCenterDelegate的方法
    func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
        
        // 检查当前显示的视图控制器是否是需要禁用推送通知的特定视图控制器
        if self is YourSpecificViewController {
            // 禁用推送通知的显示
            completionHandler([])
        } else {
            // 允许推送通知的显示
            completionHandler([.alert, .badge, .sound])
        }
    }
}
