Thanks! But I guess I still do not understand. If I release theData at the end of the method, when the other thread executes, that storage will be gone, won't it?

In the modified code I showed you, theData starts out with a retain count of 1, because you created it with alloc. When you call retain before storing it away the retain count becomes 2, and when you call release at the end of the method its retain count becomes 1 again. In the next iteration, when you release temp, its retain count falls to 0 and it'll be deallocated. In this case, you could avoid calling retain and release for theData altogether -- its retain count starts out at 1 and would just stay at 1 until you release temp it in the next iteration.

Coding the way I suggested merely saves you from even having to think about the retain count.

That is what was missing in my understanding. Thanks! -Chuck-
