使用 SwiftUI 在 WatchOS 中实现从主控制器到基于页面的控制器的导航的问题 [英] Issues implementing navigation from a main controller to page based controllers in WatchOS using SwiftUI
问题描述
我正在尝试做类似
如您所见，故事板中没有任何 segues 或 下一页关系.
我正在 HC3 的 WKHostingController(三者中的中间一个)中的代码中实现这些.
HC3的HostingController:
class HC3:WKHostingController{覆盖 func 唤醒(带上下文上下文:任何?){super.awake(withContext: 上下文)WKInterfaceController.reloadRootPageControllers(withNames: ["HC2", "HC3", "HC4"], 上下文: [context] , 方向: WKPageOrientation.horizontal, pageIndex: 1)}覆盖 var 主体:CV {返回简历()}} 问题是我无法在基于页面的视图之间导航.
其他 HostingController 有一个 WKHostingController 类型的类，如下所示:
class HC[#]: WKHostingController{覆盖 var 主体:CV {返回简历()}} 他们在身份检查器中分配了类，并且在属性检查器中也有指定的 ID.
我使用 NavigationLink 从主控制器导航到基于分页的控制器，这是视图或主托管控制器:
struct ContentView: 查看 {var主体:一些视图{NavigationLink(目的地名称:HC3"){Text("转到 HC3")}}}示例:
尝试导航到基于页面的控制器中的其他页面时，我确实在控制台中遇到了一些错误:

否则，您必须在 HC3 设置中添加 conditional_once.

So far I have the ability to go from one main view to a page based views but I cannot scroll between the page views.
The storyboard looks like this:
As you can see I do not have any segues or next page relationships in the storyboard.
I'm implementing those in code in the WKHostingController of HC3 (the middle one of the three).
HostingController of 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()
}
}
The issue is that I cannot navigate between the page based views.
The other HostingControllers have a a class of type WKHostingController as follows:
class HC[#]: WKHostingController<CV> {
override var body: CV {
return CV()
}
}
They have the classed assigned in the Identity inspector and they also have the specified ID in the Attributes inspector.
Im navigating from the main controller to the paged based controllers by using a NavigationLink Here is the View or the main hosting controller:
struct ContentView: View {
var body: some View {
NavigationLink(destinationName: "HC3"){
Text("Go to HC3")
}
}
}
Example:
I do get some errors in the console when trying to navigate to other pages in the page based controller:

There is a logic error in your design. The reloadRootPageController function should be called in the top WKHostingController but "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()
}
}
If reloadRootPageControllers is called in HC3, the strange situation is what you met.
Otherwise, you have to add a conditional_once in your HC3 setting.
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()
}
}
