点击本地推送通知时如何跳转至指定页面？iOS星座APP问题

问题根源排查 #

• 未设置通知中心代理：若未在AppDelegate的启动方法中绑定代理，通知回调不会触发，系统默认打开首页。
• 页面跳转逻辑错误：直接替换rootViewController的方式，在APP已启动（后台/前台）场景下可能失效，还会破坏原有导航结构。
• 标识匹配问题：需确认Storyboard中目标控制器的ID为deneme，且类名与代码中的detailView完全一致（建议Swift类名首字母大写，改为DetailView避免潜在问题）。

修正后的代码实现 #

1. 完善AppDelegate的通知代理绑定 #

在AppDelegate的启动方法中添加代理设置：

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    // 其他初始化代码
    UNUserNotificationCenter.current().delegate = self
    return true
}

2. 优化通知点击回调逻辑 #

区分APP状态，采用更稳妥的跳转方式：

extension AppDelegate: UNUserNotificationCenterDelegate {
    // 前台收到通知时的回调（按需实现）
    func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
        completionHandler([.alert, .sound])
    }

    func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
        guard response.notification.request.identifier == "asd" else {
            completionHandler()
            return
        }

        let storyboard = UIStoryboard(name: "Main", bundle: nil)
        guard let targetVC = storyboard.instantiateViewController(withIdentifier: "deneme") as? DetailView else {
            completionHandler()
            return
        }

        // 根据APP当前状态处理跳转
        if let rootVC = self.window?.rootViewController {
            if let navVC = rootVC as? UINavigationController {
                // 根控制器是导航控制器时，直接push目标页面
                navVC.pushViewController(targetVC, animated: true)
            } else {
                // 否则以present方式打开
                rootVC.present(targetVC, animated: true)
            }
        } else {
            // APP未启动时，将目标页面设为根控制器（可嵌套导航控制器）
            self.window?.rootViewController = UINavigationController(rootViewController: targetVC)
            self.window?.makeKeyAndVisible()
        }

        completionHandler()
    }
}

3. 修正本地推送代码的拼写错误 #

func checkPermission() {
    let notificationCenter = UNUserNotificationCenter.current()
    notificationCenter.getNotificationSettings { settings in
        switch settings.authorizationStatus {
        case .authorized:
            self.dispatchNotification()
        case .denied:
            return
        case .notDetermined:
            notificationCenter.requestAuthorization(options: [.alert, .sound]) { didAllow, error in
                if didAllow {
                    self.dispatchNotification()
                }
            }
        default:
            return
        }
    }
}

func dispatchNotification() {
    let identifier = "asd"
    let userNotification = UNUserNotificationCenter.current()
    let content = UNMutableNotificationContent()
    content.title = "Hu huu"
    content.body = "Yeni Geldi Yorumlar..."
    content.sound = .default
    let hour = 22
    let minute = 29
    let isDaily = true

    let calendar = Calendar.current
    var dateComponent = DateComponents(calendar: calendar, timeZone: TimeZone.current)
    dateComponent.hour = hour
    dateComponent.minute = minute

    let trigger = UNCalendarNotificationTrigger(dateMatching: dateComponent, repeats: isDaily)
    let request = UNNotificationRequest(identifier: identifier, content: content, trigger: trigger)

    userNotification.removePendingNotificationRequests(withIdentifiers: [identifier])
    userNotification.add(request)
}

额外注意事项 #

• 确认Storyboard中目标控制器的Storyboard ID为deneme，类名与代码中的DetailView完全匹配（注意大小写）。
• 若APP使用iOS 13+的SceneDelegate，需在SceneDelegate中同步处理通知回调逻辑，或确保AppDelegate的window设置正常。
• 测试时需覆盖APP后台、完全关闭两种状态，验证跳转效果。
