I have some questions regarding the UIDocumentPicker in iOS in terms of how can developer customize the content displaying to the user: In the official document, it says there're 2 ways of presenting the Document Picker:
- the menu of available storage the most recent used document picker
- the most recent used doc picker.
I'm wondering if there's an option for user to choose what's the 'landing App Container'. For example, if I'm using Pages, I want the Pages folder in the iCloud drive to display first, then the user have the option to return to the main directory and choose other app containers.
