swift - 关于SKStoreReviewController.requestReview()的回调

Question

如果显示从 View Controller 启动的审核弹出窗口，由于缺少 SKStoreReviewController.requestReview( )。

我想在审查弹出窗口关闭时调用 becomeFirstResponder()。有什么想法吗？

有没有办法扩展 SKStoreReviewController 并以某种方式添加回调？

警告这可能会在某个时候中断。

第 1 步:将此代码添加到您的 didFinishLaunchingWithOptions

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.
    let windowClass: AnyClass = UIWindow.self

    let originalSelector: Selector = #selector(setter: UIWindow.windowLevel)
    let swizzledSelector: Selector = #selector(UIWindow.setWindowLevel_startMonitor(_:))

    let originalMethod = class_getInstanceMethod(windowClass, originalSelector)
    let swizzledMethod = class_getInstanceMethod(windowClass, swizzledSelector)

    let didAddMethod = class_addMethod(windowClass, originalSelector, method_getImplementation(swizzledMethod!), method_getTypeEncoding(swizzledMethod!))

    if didAddMethod {
        class_replaceMethod(windowClass, swizzledSelector, method_getImplementation(originalMethod!), method_getTypeEncoding(originalMethod!))
    } else {
        method_exchangeImplementations(originalMethod!, swizzledMethod!)
    }

    return true
}

第二步:添加这个类

class MonitorObject: NSObject {
    weak var owner: UIWindow?

    init(_ owner: UIWindow?) {
        super.init()
        self.owner = owner
        NotificationCenter.default.post(name: UIWindow.didBecomeVisibleNotification, object: self)
    }

    deinit {
         NotificationCenter.default.post(name: UIWindow.didBecomeHiddenNotification, object: self)
    }
}

第 3 步:添加此 UIWindow 扩展

private var monitorObjectKey = "monitorKey"
private var partialDescForStoreReviewWindow = "SKStore"

extension UIWindow {
    // MARK: - Method Swizzling
    @objc func setWindowLevel_startMonitor(_ level: Int) {
        setWindowLevel_startMonitor(level)

        if description.contains(partialDescForStoreReviewWindow) {
             let monObj = MonitorObject(self)
             objc_setAssociatedObject(self, &monitorObjectKey, monObj, objc_AssociationPolicy.OBJC_ASSOCIATION_RETAIN_NONATOMIC)
        }
    }
}

第 4 步:将其添加到 Controller 的 ViewDidLoad 中您想要的地方

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
    NotificationCenter.default.addObserver(self, selector: #selector(windowDidBecomeHiddenNotification(_:)), name: UIWindow.didBecomeHiddenNotification, object: nil)
}

第五步:为通知添加回调并检查关联对象是否匹配

@objc func windowDidBecomeHiddenNotification(_ notification: Notification?) {
    if notification?.object is MonitorObject {
        print("hello")
    }
}

现在，当评论对话框关闭时，将触发通知并调用 'print("hello")。
