Description Randall Schmidt 2014-08-19 13:17:37 UTC
Run the attached project and take a HeapShot. Notice that there are 3 ContainerObjects in memory. There should be zero.

The three ContainerObjects are created in FinishedLaunching and no reference to them is kept. The constructor of ContainerObject does nothing but instantiate a LeakedViewController and a UIPopoverController containing it. LeakedViewController does nothing but contain a reference to an Action.

Disposing of the UIPopoverController solves this leak. However that is unwieldy and error-prone in practice.
