问题
In previous versions of Instruments I had no problem but now (v6.2) for some reason Allocations won't list any of my app's objects. I've tried Debug and Release Mode:

Note, the filter "VC" should catch all the ViewControllers. And without the filter...

Any ideas?
回答1:
I tested this out with both 6.2 and 6.3 and encountered the issue. Also I was using the iOS 8.2 and 8.3 simulators. However, when I switched to the iOS 8.1 simulator, it worked properly. So it's not so much a bug with Instruments as it is an iOS bug, it appears, or at the very least a combination of the two.
So a workaround for now is to test Allocations using iOS 8.1 or earlier.
