IOS user interface performance profiling

So far, I have always tested the performance (that is, "smoothness") of my iOS user interfaces informally, testing the interface itself. This is obviously not a very accurate way to profile performance, so I wondered if there are any methods / tools that are designed for this. There is?

Use the Core Animation tool to measure graphics (and therefore the UI). Mostly in the form of frame rates (which is a formal way to measure smoothness), but you can also configure it to display overlapping and mixed views (which your GPU absolutely hates).

In addition, there are some great WWDC sessions for iOS developers.
