iOS Question [B4XPage] Hide keyboard not working in Disappear event

[Alexander Stolte]

The code is executed, but the keyboard remains open, why?

Private Sub B4XPage_Disappear
    B4XPages.GetNativeParent(Me).ResignFocus
End Sub

I saw it as well. This is how the OS behaves.

Theoretically (I did not try) it's possible to call endEditing:true to root panel.

resignFirstResponder vs. endEditing for Keyboard Dismissal

In Swift, both [someTextField].resignFirstResponder() and self.view.endEditing(true) accomplish the same task - hiding the keyboard from the user's view and de-focusing whatever text field was usin...

Practically this should also work.

 

[Erel]

Root.As(NativeObject).RunMethod("endEditing:", Array(True))

 

[Alexander Stolte]

Root.As(NativeObject).RunMethod("endEditing:", Array(True))

It works, but unfortunately not in the Disappear event ?

According my investigations (IOS 15.1), you need to have B4XPage_KeyboardStateChanged subroutine.
Actually a behaviour is not stable in my experiments. Maybe a delay is needed.
Can you post a sample which you test ?
About Disappear I am not sure. It works (and sometimes does not work) with and without this event.

in the Attachment. Thank you.

I tested. But I don't see problems on my iPhone 6s Plus (IOS 15.1).
What I do ... I click Next Page and type text on second page. Then I press Home button (when keyboard is visible). On Home screen I press app icon and iPhone shows the second page without keyboard.

Try to replace to

Private Sub B4XPage_Disappear
    Root.As(NativeObject).RunMethod("endEditing:", Array(True))
    Do While isKeyboardOpen
        Sleep (10)
    Loop
End Sub

Then I press Home button (when keyboard is visible).

I use the swipe gesture to go to the previous page, there it does not work

If I understand a problem correctly, you can change a name of subroutine - B4x_Appear instead of B4x_Disappear. No another changes.
