I have some key commands registered in Responder chain on IOS application that reacts to F1-F12 keys. I have bluetooth keyboard connected to ipad that has some default functions assigned to most of F keys and because of that my application doesn't react when i click F key and fires the default behaviour. For example i have callback registered on F1 key that has default function of dimming the screen. When i click F1 key the screen is dimmed and the callback is not fired. When i click on F5 which does not have any default function the callback is called properly. How can i disable this default behaviour or somehow make my application react to FKeys?
Keyboard model: A1644
Ipad 6
