Answer 1

in ur XCODE (4.3) next the play button :) (run)

select : edit scheme

the scheme management window will open

click on the Arguments tab

you should see : 1- Arguments passed on launch 2- environment variables

inside the the (2- environment variables) place Name: NSZombieEnabled
Value: YES

And its done....

Answer 2

To enable Zombie logging double-click the executable in the executables group of your Xcode project. At this point click the Arguments tab and in the Variables to be set in the environment: section, make a variable called NSZombieEnabled and set its value to YES.

Answer 3

In XCode 4.0: To detect NSZombie in Instruments, select the Simulator as your target (can't detect NSZomboe on device). Run Instruments (CMD+I) and select "Zombies" trace template. Enjoy.

Answer 4

In the preferences of your executable add the environment variable NSZombieEnabled and set the value to YES.

Answer 5

It's a simple matter of setting an environment variable on your executable (NSZombieEnabled = YES), and then running/debugging your app as normal.If you message a zombie, your app will crash/break to debugger and NSLog a message for you.

For more information, check out this CocoaDev page: http://www.cocoadev.com/index.pl?NSZombieEnabled

Also, this process will become much easier with the release of 10.6 and the next versions of Xcode and Instruments. Just saying'. =)

Answer 6

Environment variables are now part of the "scheme".

To edit the scheme and turn on zombies:

• In the "Product" menu, select "Edit Scheme".

• Go to the "Run Foo.app" stage in the left panel, and the "Arguments" tab on the right.

• Add NSZombieEnabled to the "Environment Variables" section and set the value to YES, as you could in Xcode 3.

In Xcode 4.1 and above, there's also a checkbox on the "Diagnostics" tab of the "Run" stage to "Enable Zombie Objects".
