I am developing a security application. I need to disable the multitasking snapshot from being taken by iOS. I have made a fix for this by adding a black screen over my application window, when application resigns active mode. This logic seems to work fine when I press home button. But when I lock the screen, the logic is not effective, since the snapshot is already taken before control comes to applicationWillResignActive method. I have verified this by downloading the container folder from devices tab. Is there any way to fix this?
Thanks in advance!
