Answer 1

You need to launch the Instruments application with the Zombies instrument from outside of XCode

This is how you can do it:

The Instruments application is usually located inside /Developer/Applications/, but you can also use Spotlight to find it.

When Instruments starts you should be presented with a screen that asks you to choose a template for the new Trace Document.

Select: iPhone Simulator > Memory > Zombies

Next you need to choose a target.

Go to: Chose target > Chose target > Chose target...

Now you need to select the application file:
/build/Debug-iphonesimulator/
and press Chose.

Now you are all set.

To launch you application press the Record button.

A few Side Notes:

• I used XCode 3.2.3 on Mac OS X 10.6.3, but I believe it works the same on previous versions.
• The Zombies instrument only works with the simulator.
• The Zombies instrument cannot be used with the Leaks instrument because all the zombies would appear as leaks.
• I would also like to know why the menu in XCode is grayed out.
