Difference between NSThread and detachNewThreadSelector:toTarget:withObject:

In the NSThread documentation, I came across the method detachNewThreadSelector:toTarget:withObject:. What's the difference between that method and creating a thread with initWithT开发者_C百科arget:selector:object: and then starting it with start?

The only difference is that the second way gives you a reference to the NSThread object, so you can do things like set the stack size or priority before starting it, or use the isExecuting/Finished/Cancelled methods to check its status later.
