Xcode Instruments - Enable NSZombie Detection? Where is it?

Question

I have watched this video http://www.markj.net/iphone-memory-debug-nszombie/

The guy shows an option called Enable NSZombie Detection on Allocations inside instruments, but my Instruments doesn't shows this option. This guy's video was done using a one year old version of Instruments and I am using Xcode 3.2.5. Do you guys know where this option is now? How can I enable it for iPhone apps?

thanks

Answer 1

In XCode 4.0, this 'Enable Zombie' option is only present in iPhone simulator and not when you profile on actual device.

Answer 2

The zombie option is available in Xcode 3.2.6 under the allocations tool if you run in the simulator. For debugging memory crashes due to too many dealloc, the simulator will work just as well as the device nearly every time. BTW I am 'The guy' in the question ;-)
