iOS Question Activity_KeyPress detection

[Ertan]

Hi
I want to create an event when the power button of the phone is pressed in my project.

Keycodes it can not be found.

Main - 119: Undeclared variable 'keycodes' is used before it was assigned any value.

I don't have a problem with Android phones.
I could not find a solution in the forum.

You cannot intercept the power button in Android or in iOS.
