In #100, I mentioned Reveal which provides a web browser-like development tool, that lets you examine and manipulate your app's view hierarchy.

Flipboard has also open sourced FLEX, a debugging tool that serves a similar purpose, but runs in-app, so it's possible to rig your app so that when you are testing it on your device — it works in the simulator too – and spot something wrong, you can bring up the toolbar and examine your views.

Check it out!
