我目前有父母"菜单" TableView
UINavigationBar
cell
reference outlet
Views
View
有buttons
到3个类似Views
的不同信息。
在每个button
中,有View
到其他2 View
。
每个UINavigationBar
的segue会打开另一个back button
。
问题:
从每个View
back button
' Bar Button Item
返回我之前的UINavigationController
,但我尝试将cd C:\Users\%username%\AppData\Local\Apps\2.0\V7MK47Q8.0NZ\KLJLETPC.4RJ\micr..tion_d8f8f667ee342b5c_0010.0000_6b4a13fd451b1c00
Import-Module .\CreateExoPSSession.ps1
Connect-EXOPSSession -UserPrincipalName name@domain.com
设置为" menu" 。
其他var ref = firebase.database().ref().child("datos").child("pedidos").child("nuevos");
及其中的segue效果非常接近,但是segue动画与tell application "Finder"
set theFile to some file of folder "Macintosh HD:Users:user:Desktop:lv:"
end tell
set randomImage to POSIX file theFile
tell application "Messages"
set targetBuddy to "appleid@mac.com"
set targetService to id of 1st service whose service type = iMessage
set textMessage to randomImage
set theBuddy to buddy targetBuddy of service id targetService
send textMessage to theBuddy
end tell
中的动画不同。
如何清除segue中的UINavigationBar转换历史到初始视图?
答案 0 :(得分:1)
您可以尝试弹出到根视图控制器,或者您可以编辑导航控制器viewControllers
属性并删除/添加一些VC。
您也可以尝试Unwind Segue机制。

以下是导航控制器提供弹出操作的一些方法(功能)。他们从弹出的导航堆栈返回可选的UIViewController(intance)。
open func popViewController(animated: Bool) -> UIViewController? // Returns the popped controller.
open func popToViewController(_ viewController: UIViewController, animated: Bool) -> [UIViewController]? // Pops view controllers until the one specified is on top. Returns the popped controllers.
open func popToRootViewController(animated: Bool) -> [UIViewController]?
以下示例代码作为查询的解决方案::
// if you want to back to root of your app
if let rootNavigationController = self.window?.rootViewController as? UINavigationController {
rootNavigationController.popToRootViewControllerAnimated(true)
}
// But if you want to back to root of your current navigation
if let viewcontroller = self.storyboard?.instantiateViewController(withIdentifier: "NewViewController") as? NewViewController { // or instantiate view controller using any other method
viewcontroller.navigationController?.popToRootViewControllerAnimated(true)
}
