i’m having a time of it tracking down a resource allocation bloat culprit in an iPhone app i’m working on. i’ve narrowed it down to when i’m rapidly updating the center property of a UIImageView. a snippet from the Instruments application is below:

there are hundreds (if not thousands) of these messages, and the object allocation graph trends steadily upwards. when i disable the portion of the method which updates the center property the allocations stop and the memory usage goes flat. this also only occurs on the device…the simulator does not exhibit this behavior.

i’m using UIImageView directly, without subclassing, and it contains data from a small PNG file. i’ve patched up several other leaks successfully today, and really wanted to nail this one too.
