iOS 通过屏幕时间API实现应用上锁和隐藏【更新】

(最近有小伙伴说申请权限时间太长，没反应。我分享下我的一次授权经历：我有一次也是等了个把月，后面问了客服，说没有渠道去查询状态或者加急，所以重新提交了一遍权限申请，第三天就收到了授权成功的邮件。仅代表个人经历，非绝对)

经过一段时间断断续续的琢磨，终于实现了在自己App内实现应用隐藏、上锁和解锁的功能。

授权

AuthorizationCenter.shared.requestAuthorization(for: .individual)

获取列表

.familyActivityPicker(isPresented: $isLockPresented, selection: $lockModel.selectionToLock)

上锁和隐藏

store.shield.applications = applications.isEmpty ? nil : applications
store.shield.applicationCategories = ShieldSettings.ActivityCategoryPolicy.specific(categories, except: Set())

被锁的App页面定制

App上锁后，打开这个App会出现如下页面：

如何自定义页面？

直接上代码

class ShieldConfigurationExtension: ShieldConfigurationDataSource {
    override func configuration(shielding application: Application) -> ShieldConfiguration {
        let appname = application.localizedDisplayName ?? ""
        return ShieldConfiguration(
            backgroundBlurStyle: UIBlurEffect.Style.light,
            backgroundColor: UIColor.white,
            icon: UIImage(named: "ic_unlock_gb"),
            title: ShieldConfiguration.Label(text: "\(appname) \(localizedString("title_shield_unlocked"))", color: .black),
            subtitle: ShieldConfiguration.Label(text: localizedString("title_shield_text"), color: .black),
            primaryButtonLabel: ShieldConfiguration.Label(text: localizedString("title_shield_button"), color: .white),
            secondaryButtonLabel: ShieldConfiguration.Label(text: "", color: .white)
          )
    }

可以看到使用的是ShieldConfigurationExtension

如何响应自定义页面的按钮点击？

class ShieldActionExtension: ShieldActionDelegate {
    override func handle(action: ShieldAction, for application: ApplicationToken, completionHandler: @escaping (ShieldActionResponse) -> Void) {
        // Handle the action as needed.
        switch action {
        case .primaryButtonPressed:
            sendNotification(application: application)
            completionHandler(.defer)//close
        case .secondaryButtonPressed:
            completionHandler(.defer)
        @unknown default:
            fatalError()
        }
    }

可以看到使用的是ShieldActionExtension

本文也是给有经验的伙伴准备的，所以不做一些基础的创建之类的说明。

参考文档

There is a video about it from WWDC 2021 called Meet the Screen Time API: [https://developer.apple.com/videos/play/wwdc2021/10123/](https://developer.apple.com/videos/play/wwdc2021/10123/)

There are actually 3 APIs (none of them have Screen Time in the name)

*   Managed Settings ([https://developer.apple.com/documentation/ManagedSettings](https://developer.apple.com/documentation/ManagedSettings))
*   Family Controls ([https://developer.apple.com/documentation/familycontrols/](https://developer.apple.com/documentation/familycontrols/))
*   Device Activity ([https://developer.apple.com/documentation/deviceactivity/](https://developer.apple.com/documentation/deviceactivity/))
