How to use NSZombie?

So I just finished my app and I wanted to as the final few steps run some diagnostics on it. In terms of what its memory usage, allocations, leaks, etc are.

I have a few questions: 1) Is there a standard list of instruments/checks I should run on my app be fore its submitted to make sure its robust? If so could s开发者_运维问答omeone point me to some links and/or tell me some names so I can google the stuff.

2) One of the tools I know to run is NSZombieEnabled. I followed the steps I found online on some sites to set up this NSZombie test but it doesn't seem to be working. I looked at this site: NSZombieEnabled

This is what my XCode looks like after I tried the steps listed there:

But why is the zombies choice not highlighted?

Once I get it to work how do I actually use NSZombies?

So far from what I know, NSZombies is only available for debugging Mac apps or ios apps running on the simulator. It cannot be used for apps running on i devices.
