Device detection computer vs iOS

Hi, is there any way to detect the type of device to use touch instead of mouse ?

if (computer) do something; // or if exist mouse ?
if (iOS) do something;

thanks

Perhaps this is what you’re seeking?

Either that or this Unity - Scripting API: Application.platform

thanks Aerozo, it works perfectly!
