我有两个故事板,一个包含应用程序的所有内容,另一个包含我的应用程序的“入职”/教程。
完成教程后,我想导航回原始视图控制器。
这是我导航到其他故事板的代码:
let defaults = UserDefaults.standard
if defaults.bool(forKey: "firstOpened") {
print("First VC launched")
}else{
var vc: UIViewController
let goTo = UIStoryboard(name: "Onboarding", bundle: nil).instantiateViewController(withIdentifier: "notificationStoryboard") as! FirstOnboardingViewController
self.present(goTo, animated: true, completion: nil)
}
有了这个,它可以工作,除了TabBarController没有显示,并且没有按照我想要的方式工作。
这是我导航回Main.Storyboard的代码:
@objc func handleSecondPush() {
//registerForRemoteNotifications()
UserDefaults.standard.set(true, forKey: "firstOpened")
let goTo = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "pushToFeedVC")
self.present(goTo, animated: true, completion: nil)
//self.performSegue(withIdentifier: "goToLink", sender: nil)
}
我也在其他Storyboard中尝试了这个,但是这个按钮不会改变视图:
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let controller = storyboard.instantiateViewController(withIdentifier: "MainTabBarController") as! UITabBarController
print(controller)
self.window?.rootViewController = controller
self.window?.makeKeyAndVisible()
if let tabBarVc = self.window?.rootViewController as? UITabBarController {
tabBarVc.selectedIndex = 1
}
问题简短:所以我的问题是,如何从不包含导航控制器或TabBarController的故事板导航回main.storyboard,其中包含选定索引为1的TabBarController?
当您展示入职时,您应该返回带有的标签
self.dismiss(animated:true,completion:nil)
对于复杂的演示文稿,您可以轻松地重新进行此操作
let vc = storyboard.instantiateViewController(withIdentifier: "MainTabBarController") as! UITabBarController
(UIApplication.shared.delegate as! AppDelegate).window!.rootViewController = vc
更好的是
let goTo = UIStoryboard(name: "Onboarding", bundle: nil).instantiateViewController(withIdentifier: "notificationStoryboard") as! FirstOnboardingViewController
let nav = UINavigationController(rootViewController:goTo)
nav.isNavigationBarHidden = true
self.present(nav, animated: true, completion: nil)
onbarding内部的流程应该是pushViewController
然后在最后的入职vc中解雇
if let tab = (UIApplication.shared.delegate as! AppDelegate).window?.rootViewController as? UITabBarController {
tab.dismiss(animated:true,completion:nil)
}
