我们知道,要实现PageTabBarController,我们需要在AppDelegate.swift中插入这些代码:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions:
let viewControllers = [MatchDetailViewController(),ListPlayersViewController(),ChatViewController()]
window = UIWindow(frame: Device.bounds)
window!.rootViewController = MatchViewController(viewControllers: viewControllers, selectedIndex: 0)
window!.makeKeyAndVisible()
}
现在,当我想打开匹配数据的详细信息时,我需要使用PageTabBarController。我的问题是,如何实现它而不在AppDelegate.swift中插入这些代码,因为它将在第一次应用程序启动时打开我的MatchViewController(从PageTabBarController扩展)。
我已经尝试过这段代码,但它会导致崩溃,并且它指向我的AppDelegate.swift
class MatchViewController: PageTabBarController {
var window: UIWindow?
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
open override func prepare() {
super.prepare()
let viewControllers = [MatchDetailViewController(),ListPlayersViewController(),ChatViewController()]
//1st try: Crash
window = UIWindow(frame: Device.bounds)
window!.rootViewController = MatchViewController(viewControllers: viewControllers, selectedIndex: 0)
window!.makeKeyAndVisible()
//2nd try: error
self.rootViewController = MatchViewController(viewControllers: viewControllers, selectedIndex: 0)
//3rd try: crash
self.viewControllers = viewControllers
delegate = self
preparePageTabBar()
}
fileprivate func preparePageTabBar() {
pageTabBar.lineColor = Color.blue.base
pageTabBar.dividerColor = Color.blueGrey.lighten5
pageTabBarAlignment = PageTabBarAlignment.top
pageTabBar.lineAlignment = TabBarLineAlignment.bottom
}
}
extension MatchViewController: PageTabBarControllerDelegate {
func pageTabBarController(_ pageTabBarController: PageTabBarController, didTransitionTo viewController: UIViewController) {
}
}

嗨,是的,有办法。 PageTabBarController is inherited from a
UIViewController`,它允许您将其添加为任何其他UIViewController的子项。那就是说,你刚才给了我一个好主意。我将创建一个新的UIViewController,允许您添加尽可能多的子UIViewControllers,这将使这非常容易。我将此作为功能请求。
在更新之前,请使用建议的方法将其添加为子UIViewController。你熟悉怎么做吗?

首先创建AppToolbarController(ToolbarController的子类),或者您可以使用Material库演示中的那个。
然后从您的视图控制器中,您可以使用:
DispatchQueue.main.async {
let tabbarViewController = AppPageTabbarController(viewControllers: [vc1,vc2,vc3], selectedIndex: 0)
self.present(AppToolbarController(rootViewontroller: tabbarViewController))
}
