iOS Question APP crash when saving bitmap

[abarnett]

Sub lblSnapshot_Click
    Dim SnapBitmap As Bitmap
    Dim myPhone As Phone
    If panLayout.Tag="list" Then
        cvs.Initialize(gmapD)
    Else
        cvs.Initialize(gmap)
    End If
    SnapBitmap=cvs.CreateBitmap
    myPhone.AddImageToAlbum(SnapBitmap)
    ImageView1.Bitmap=SnapBitmap
End Sub

APP crashes under ios 13.3.1 but was working ok before ios update.

Probably missing a plist key.

See this example: https://www.b4x.com/android/forum/threads/addimagetoalbum-error.90657/post-573183

I have this in the Project Attributes

[CODE=b4x]    #PlistExtra: <key>NSPhotoLibraryUsageDescription</key><string>This app needs access to photos.</string>

[/CODE]

 

[Erel]

Create a new project with the code from that example. Only change the image name.

Does it work?

 

[abarnett]

running the same code on a device running ios 10.3.3 it displays the popup message 'This app needs access to photos.'. When I Allow is saves.

I don not get the popup message running on an ios 13.3.3 device

Thanks Erel. I found it needs this line also for ios 13

#PlistExtra:<key>NSPhotoLibraryAddUsageDescription</key><string>Save photo in albums.</string>
