NSBlockOperation and NSAutoreleasePool

Question

Typically, when you create an NSOperation subclass, you are responsible for creating and releasing NSAutoreleasePool in the -main method.

When you use NSBlockOperation , do you need to create an autoplay pool in a block?

Answer 1

No. The GCD (which NSOperationQueue builds on top of OS X 10.6 or iOS 4.2) manages autoplay pools for you, just like NSRunLoop does.

Answer 2

I don’t think so, since work queues have their own pools already created for you.

Answer 3

Adam,

It is best to read block memory information with objects. Here is a link to iOS Blocks and Variables at the bottom of this page contains information about the types of objects.
