我正在尝试使用SwiftUI做类似this的操作。到目前为止,我已经能够从一个主视图转到基于页面的视图,但是我无法在页面视图之间滚动。
如您所见,情节提要中没有任何segues
或next page relationships
。
我正在WKHostingController
的HC3
(三个中的一个)中的代码中实现它们。
HostingController
的HC3
:
class HC3: WKHostingController<CV> {
override func awake(withContext context: Any?) {
super.awake(withContext: context)
WKInterfaceController.reloadRootPageControllers(withNames: ["HC2", "HC3", "HC4"], contexts: [context] , orientation: WKPageOrientation.horizontal, pageIndex: 1)
}
override var body: CV {
return CV()
}
}
问题是我无法在基于页面的视图之间导航。
其他HostingControllers具有如下类型的WKHostingController
类:
class HC[#]: WKHostingController<CV> {
override var body: CV {
return CV()
}
}
它们在身份检查器中分配了类别,并且在属性检查器中也具有指定的ID。
我使用NavigationLink
从主控制器导航到基于页面的控制器,这是View或主托管控制器:
struct ContentView: View {
var body: some View {
NavigationLink(destinationName: "HC3"){
Text("Go to HC3")
}
}
}
示例:
当尝试导航到基于页面的控制器中的其他页面时,控制台中确实出现了一些[[错误:

reloadRootPageController
函数应在顶部WKHostingController中调用,但应为“ HC3”。 class HostingController: WKHostingController<ContentView> {
override func awake(withContext context: Any?) {
super.awake(withContext: context)
WKInterfaceController.reloadRootPageControllers(withNames: ["HC2", "HC3", "HC4"], contexts: [context] , orientation: WKPageOrientation.horizontal, pageIndex: 1)
}
override var body: ContentView {
return ContentView()
}
}
如果在HC3中调用了reloadRootPageControllers
,则您遇到的是奇怪的情况。否则,您必须在HC3设置中添加conditional_once。
class HC3: WKHostingController<CV> { static var runOnce: Bool = true override func awake(withContext context: Any?) { super.awake(withContext: context) if HC3.runOnce { HC3.runOnce.toggle() WKInterfaceController.reloadRootPageControllers(withNames: ["HC2", "HC3", "HC4"], contexts: [context] , orientation: WKPageOrientation.horizontal, pageIndex: 1) } } override var body: CV { return CV() } }
