iOS中UIHostingController内Swift TipKit的MaxDisplayCount失效问题

当为Tip配置MaxDisplayCount选项后，若在被UIHostingController包裹的SwiftUI视图中展示TipView，该选项会失效——Tip不会自动隐藏，会一直显示直到用户手动关闭。

Tip定义 #

struct CustomTip: Tip {
    
    var title: Text {
        Text("提示标题")
    }
    
    var message: Text? {
        Text("提示内容")
    }
    
    var options: [Option] {
        MaxDisplayCount(1)
    }
}

AppDelegate代码 #

import UIKit
import SwiftUI
import TipKit

@main
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        // 应用启动后的自定义配置点
        
        try? Tips.configure()
        
        let vc = UIHostingController(rootView: CustomView())
        window = UIWindow(frame: UIScreen.main.bounds)
        window?.rootViewController = vc
        window?.makeKeyAndVisible()
        
        return true
    }
}

SwiftUI视图代码 #

import SwiftUI
import TipKit

struct CustomView: View {
    var body: some View {
        VStack {
            TipView(CustomTip())
            Text("Hello, World!")
        }
    }
}
