I've been using -performSelectorInBackground in many of my apps, sort of oblivious to -detachNewThreadSelector. Now I am wondering what the differences are between the two. Are they pretty much interchangeable, or are there differences and places where one is superior to the other? Thanks!
Difference between [NSThread detachNewThreadSelector:] and -performSelectorInBackground

They're identical. See documentation.
performSelectorInBackground:withObject: The effect of calling this method is the same as if you called the detachNewThreadSelector:toTarget:withObject: method of NSThread with the current object, selector, and parameter object as parameters.
As Michael says, they are identical. I think, to use a thread by performSelectorInBackground:withObject: is easier way rather than NSThread.
However, NSThread can control its priority, stacksize, etc. If you'd like to customize the behavior, I recommend NSThread instead of performSelectorInBackground:withObject:.
