iOS Question Problem with DocumentPicker.Show

SDFP Studio · Jul 9, 2024

Hello,

I have a problem with DocumentPicker.Show

This way it works fine on iPhone but the picker is not displayed on iPad :

B4X:

DocumentPicker.Show(MainPage,bt_Panel_Stockage_Tel)

This way it works fine on iPhone and most iPads but on one user's iPad I have an error report :

B4X:

DocumentPicker.Show(MainPage,NavControl)

Does anyone have any ideas? Thanks

Error report:

You cannot add BarButton without a navigation bar, however more importantly, there was an issue with showing the picker on a non-BarButton view. This is fixed: https://www.b4x.com/android/forum/threads/updates-to-internal-libraries.48179/post-994165

You can actually pass Null as the view (make sure not to pass an invalid BarButton).

Erel · Jul 10, 2024

You need to pass a BarButton as the second parameter.

SDFP Studio · Jul 10, 2024

Hello Erel
I don't have a BarButton or maybe I don't know it

SDFP Studio · Jul 10, 2024

In my app (not in b4xpages mode because I stuck to the idea that rotation cannot be managed natively, but maybe that has changed since) I hide the ToolBar and the NavigationBar.

B4X:

NavControl.NavigationBarVisible = False
NavControl.ToolBarVisible = False

Can I / should I still create a BarButton (which will be invisible) to provide it to DocumentPicker?
Thanks

SDFP Studio · Jul 10, 2024

I try with that

B4X:

Dim bb As BarButton
bb.InitializeCustom(bt_Panel_Stockage_Tel)
DocumentPicker.Show(MainPage,bb)

runs on iPhone, send for test on ipad

SDFP Studio · Jul 11, 2024

After my last modification I have that error

Erel · Jul 12, 2024

There is not enough information here. You are passing a Null value or an uninitialized object.

SDFP Studio · Jul 12, 2024

Hello Erel,
bt_Panel_Stockage_Tel is initialized because it is the one that triggers this procedure.
I added the following two lines to pass bb as a parameter.

B4X:

Dim bb As BarButton
bb.InitializeCustom(bt_Panel_Stockage_Tel)
DocumentPicker.Show(MainPage,bb)

The declaration is not enough for bb?

No.

You need to add it to the navigation bar. Best to do it with the designer.

SDFP Studio · Jul 12, 2024

Thanks,
I'll look at that, knowing I'm not going to display the button, it's just to give it to DocumentPicker

SDFP Studio · Jul 13, 2024

Here is the new code I tried

B4X:

Dim DocumentPicker As DocumentPickerViewController
DocumentPicker.InitializeImport("picker", Array("public.audio","public.movie"))
If Not(bb.IsInitialized) Then bb.InitializeCustom(bt_Panel_Stockage_Tel)
MainPage.TopLeftButtons = Array (bb)
DocumentPicker.Show(MainPage,bb)

and the error code

B4X:

I know Erel that you suggested me to make the declaration under the editor but I don't know which views to add.

I must admit that with b4i I feel completely lost, everything seems complicated to me, I can no longer make my mac work in local host for example, I use the hosted builder. I try to move forward from time to time on blocking points but it takes all the time I give myself to development.

This error occurs on a user's iPad (I don't know if he is the only one) on iPhones, it works, on an iPad that I was able to test it also works and on macos it also works.
It may be a false problem.

Thanks for your help but maybe I will let it go.

Better to start a new thread. I'm sure that it is solvable (assuming that your Mac can run Xcode 15).

Erel · Jul 14, 2024

You cannot add BarButton without a navigation bar, however more importantly, there was an issue with showing the picker on a non-BarButton view. This is fixed: https://www.b4x.com/android/forum/threads/updates-to-internal-libraries.48179/post-994165

You can actually pass Null as the view (make sure not to pass an invalid BarButton).

Thank you very much erel
I'm testing this

SDFP Studio · Jul 16, 2024

It is solved !
Thank you very much erel
