关于skstoreReviewController.requestReview()的回调

skstorereviewcontroller becomefirstresponder swift

zs2020 · 技术社区 · 7 年前

如果从视图控制器启动的查看弹出窗口出现,则当弹出窗口由于缺少以下回调功能而被取消时,无法将窗口焦点切换回视图控制器: SKStoreReviewController.requestReview() .

我想打个电话给 becomeFirstResponder() 当审查弹出窗口被取消时。有什么想法吗?

有没有办法延长 skstorereview控制器 然后添加一个回调?

警告:这可能会在某个时刻中断。

步骤1:将此代码添加到DidFinishLaunchWithOptions中

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
}

步骤2:添加此类

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)
    }
}

步骤3: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:将此添加到所需控制器的viewdidLoad中

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)
}

步骤5:添加通知的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,当审查对话框关闭时,将触发通知并调用“打印”(“hello”)。
