Hi everyone

I tried to following the instruction to use NSZombie.. It doesn’t seem to work on my Xcode.

I am a brand new programming in Objective C. I even have a new environment variable NSZombieEnabled in arguments section for the Executables.
The choice ‘Enable NSZombie’ Detection did not show up in my Instrument. I wonder what’s going on?

i.e. I am not allowed to enable NSZombie detection?
Any help will be greatly appreciated!

Does this still work in instruments v.2.7 (2529)? I did not have a checkbox for “Enable NSZombie detection”…

Thanks,
Zak

nice one!
why i had this simple bug ;)
what should be done if the unnecessary release actually happens in [super dealloc] (super is a UIView)?

well anyway thanks for the eyeopening video!!

Well, after trying many different ways, and on two instances of “EXC_BAD_ACCESS” I do not get the “Zombie Messaged” popup that you get, I can set “Record reference counts” and “Enable NSZombie Detection” but mine just runs, the instrument starts recording, then just quits with recording stopped.

Sigh. Any thoughts?

Awesome! I just spent two whole evenings tracking down the release of an object …

I’m quite a xcode n00b but seems that lStr = [lStr stringByAppendingString:@","] is not keeping the lStr original settings like retain :(

lStr = [lStr stringByAppendingString:@","] retain]; fixed my problem . Not sure if this is the correct way to fix it , but for now it works ..

Thanks again !!
