iOS Question iOS open external image file with app not working

[lymey]

Hi!
I modified the code from this post: https://www.b4x.com/android/forum/threads/open-external-files-with-your-app.50525/

#Region  Project Attributes
    #ApplicationLabel: CSV Chooser
    #Version: 1.0.0
    'Orientation possible values: Portrait, LandscapeLeft, LandscapeRight and PortraitUpsideDown
    #iPhoneOrientations: Portrait, LandscapeLeft, LandscapeRight
    #iPadOrientations: Portrait, LandscapeLeft, LandscapeRight, PortraitUpsideDown

    #ATSEnabled: True
    #MinVersion: 8
    #PlistExtra:<key>CFBundleDocumentTypes</key>
    #PlistExtra:<array><dict><key>CFBundleTypeIconFiles</key><array/>
    '#PlistExtra: <key>CFBundleTypeName</key><string>CSV File</string>
    #PlistExtra: <key>CFBundleTypeName</key><string>JPEG File</string>
    #PlistExtra:<key>LSHandlerRank</key><string>Alternate</string>
    #PlistExtra:<key>LSItemContentTypes</key><array>
    '#PlistExtra:<string>public.comma-separated-values-text</string>
    #PlistExtra:<string>public.jpeg</string>
    #PlistExtra:</array></dict></array>
    
#End Region

Sub Process_Globals
    'These global variables will be declared once when the application starts.
    'Public variables can be accessed from all modules.
    Public App As Application
    Public NavControl As NavigationController
    Private Page1 As Page
    Private xui As XUI
    
End Sub
Private Sub Application_OpenUrl (Url As String, Data As Object) As Boolean
    Log("url:" & Url)
    If Url.StartsWith("file://") Then
        Dim f As String = Url.SubString(7) 'remove the file:// scheme.
        Log ("f: " & f)
        Try
            
            If File.Exists("",f) Then
                Log("file exists!")
                'Msgbox(File.ReadString("", f), "")
            Else
                Log("file does not exist!")
                Return True
            End If
            
        Catch
            Log(LastException.Message)
            Msgbox("Error loading file", "")
        End Try
    End If
    Return True
End Sub

The code above works for files such as Whatsapp attachments (I can see the app and can share ok), but not with files in Photos (the app does not show up in the list of apps that you can share the image with). Am I missing a PListExtra entry perhaps?
I tried adding:

#PlistExtra:<key>NSPhotoLibraryUsageDescription</key><string>So we can manipulate your photos and videos.</string>

but it didn't make any difference.
I am using an iPhone 7 with iOS 14.01
Thanks for any help I can get!

There are two distinct actions:
- Open a file with an external app.
- Share a file with an external app.

The second case requires building an app extension. This is something that is not supported by B4i.
