Your question is somewhat not specific but here some tips.

1- hijack application UIWindow

2- create a boolean variable 

3- create a UISwitch with event  "valueChanged" to change the boolean variable value based on the switch toggle state

4- add the UISwitch you created to the app's UIWindow

4- on your hooked function simply check if variable is true or false.

 

Btw, GL_LINE_LOOP can cause performance issue for some low end devices. You can use glDepthRangef(0.5, 1) to draw an element on screen coordinates level then simply enable and write rgb color into the frame buffer via glColorMask & glEnable & glBlendFunc, finally draw the element then disable the buffer to be back to normal (-:
