I test SaveState on my iPad, I follow exactly the same logic on the embarcadero SaveState example, but it throws an exception after saving data.
However, the same logic tested on iOS Simulator is working fine.
I am using Delphi 10.3.1 with an iPad iOS12.2
When I click the home button after the FormSaveState logic executed, the below exception occurred:
Cannot create file ……. Operation not permitted
The same logic tested on iOS Simulator is working fine.
Any idea why this occurred and how to resolve? Thanks for any help!
