Targets iOS

Anyway to accomplish this:

Screen A Goes to Screen B
Screen B Goes to Screen C
Screen C Goes to Screen D
want back button on Screen D to go back to Screen A

Thanks

Where does the back button go for B and C? Both back to A?

3

Presently no. They would go back to the previous screen. Just want D to go back to A.

Thanks.

You’ll need to use iOS Design Extensions, and put this code in the open even of Screen D:
Self.SetHidesBackButtonXC(True)

Then add a toolbar button with “Back to Screen A” (or whatever).

In the ToolbarButtonPressed event handler add your code to go back to Screen A

If ScreenA is the top level screen:

In the ToolbarButtonPressed event handler use

self.PopToRootViewControllerXC //Returns to the initial view in the view controller stack

Good Stuff thanks.

What if A is not the top level screen ?

If A is not the top level screen, I would inform screen C that it needs to close when D closes.
And inform B it needs to close when C closes.

There are various ways of doing this.
My favorite way would be using delegates.
My second favorite would be using JK_NotificationCenter from iOSKit.
