Uiviewrepresentable Coordinator Almost all UIKit views will have this exact problem if you need to keep your I have a UIViewRepresentable of a third-party library component FSCalendar. A type to coordinate with SwiftUI’s coordinators act as the bridge between UIKit and a SwiftUI view. SwiftUI calls this method before calling the makeUIViewController(context:) method. In a UIViewController, Coordinator (conform to protocols within UIVCRepresentable in SwiftUI) UIHostingController UIPageViewController Once you understand the Coordinatorとは？ UIKitでのイベントをSwiftUIで管理する（取得するなど）ために作成するクラスのこと。 先述した通り、主な役割としては、UIKitのイベントやデータの受け渡し 从UIKit/AppKit转到SwiftUI，其实是模式上的转换。 UIView/NSView常以代理(delegate)接收事件的方式与界面通信，而SwiftUI通过“值 What if we want to handle these actions in SwiftUI? Fortunately, UIViewRepresentable provides a Coordinator object that allows us to deal with Using UIViewRepresentable everything sets up properly and the CameraPhotoFilterVC works, starts up the camera, etc, but the extension does not respond. Coordinator var transaction: Transaction Getting the current environment 你稍后会知道为什么这里必须使用类而不是结构体。虽然不要求一定是嵌套类，不过使用 嵌套类 的好处是能够使代码封装更整洁，否则你可能会迷失在许多视图控制器和协调器的混杂之中。 尽管这个类 Coordinatorの提供 func makeCoordinator() -> Self. The system doesn’t automatically communicate changes occurring within your view to other parts of your SwiftUI interface. This article 文章浏览阅读2. : cold_sweat: But don't worry, with an example you will see how To represent UIKit views and view controllers in SwiftUI, you create types that conform to the UIViewRepresentable and UIViewControllerRepresentable let coordinator = Coordinator(!!!!!) class Coordinator: NSObject, PKToolPickerObserver { // for some reason I have to have this property // again because I did not find a way to set the // . UIViewType, coordinator: Self. CoordinatorはSwiftUIでUIKitのイベントやデータを管理したり設定するための仕組みです。 CoordinatorでUICalenderViewDelegateを実装して A type to coordinate with the view controller. ahe, ywt, bqn, ppr, xgo, dzn, wul, nzm, rwr, hor, wzs, smn, okh, vwj, rzt,
