[MonoTouch] Monotouch issue with Xcode's Instruments

[Rolf Bjarne Kvinge]

Hi René,

Here is a screencast for you: http://screencast.com/t/NUekvWSque5s.

Btw, it looks like the "Memory Tag 70" row has (finally) been renamed to
"GC Image". If you expand that row you'll see the CG instances which uses
memory - you can then go to the Allocations tool and drill into the CGImage
instances created to find out where each instance was created.

I hope this helps,
Rolf
