Simulate Home click or close app in iOS

Hi mates,

Does anybody know how to simulate the home click, put the application run in the background or just kill it, I know that this is not the proper way to do it, and we shouldn't mess with this kind of things since those are handled by the OS itself,

but if someone knows a workaround to this it will be very helpful,

for android was pretty easy, by using:
Android.OS.Process.KillProcess(Android.OS.Process.MyPid());

thanks!
