enabling guard malloc for Iphone device or for store kit api?

I am using store kit api for an application on iphone. I would like to know if it is possible to enable Malloc Guard while running on 开发者_StackOverflow中文版the device and see if there are any memory leaks. Could someone let me know if it is possible?

This page doesn't mention it is possible, quoting:

You can use this option both Mac OS X applications and also for iPhone applications running in the simulator.

So I guess it's a no-go on the device.
