Question

Answer 1

+2 A:

Which version of Xcode are you using? Thread names are only supported in Mac OS X 10.6 and Xcode 3.2.

I am using OSX 10.5 and Xcode 3.1.4. So no chance there? No chance at all in OSX 10.5? In the doc for NSThread:setName, it says available in Mac OS X v10.5 and later.

The docs say supported from 10.5 on.

Yes, but the threadname is not propagated from the Objective-C layer to the runtime threads layer in 10.5, because the pthread_setname_np API doesn't exist until 10.6, and you need Xcode 3.2 to fetch and display the thread name.

cdespinosa 2010-01-14 05:01:35

So, Xcode 3.2 on MacOSX 10.5 would be able to display thread names if I propagate the threadnames to the runtime threads layer? How can I do that?

No, Xcode 3.2 is 10.6 only. If you want to see thread names in the Xcode UI, you have to use Xcode 3.2 on Mac OS X 10.6.

Just want to say this explicitely for other readers: pthread_setname_np is the solution.

Answer 2

A:

I recommend the following:

[[NSThread currentThread] setName:@"My thread name"]; // For Cocoa  
pthread_setname_np("My thread name"); // For GDB.

(You'll need to include pthread.h) Works a treat in XCode 3.2.3 (at least for iPhone development)
