@autoreleasepool in loop or loop in @autoreleasepool?

Question

It\'s a good practice to put lots of autoreleased object in an autoreleasepool at loop action. I found someone put the @autoreleasepool in loop but others p

Answer 1

In your first example for every iteration the pool is drained. This makes sense if the body of the iteration involves a lot of autoreleased objects.

The second example will only drain the pool once after the loop.

So if the internals of the loop are causing the memory bloat then go for option one. If the memory bloat over the whole loop is acceptable then loop then use option two.
