Since the field is a currency field, however, I want the number to always display with two decimal places. You've probably seen this type of an interface at an ATM.

I need to mask a whole animation that takes place in a UIImageView. I tried subclassing the UIImageView and doing the masking in its drawRect call but that doesn't get called on every frame of the animation as I expected (it doesn't get called at all actually) even though the animation plays fine. Anyone has any experience on this? ...
When I select "Shake Gesture" from the Hardware menu in the iPhone simulator, my first responder always receives two shake events (with a few milliseconds in between). Unfortunately these two events in the simulator lead to a problem with an UIScrollview that should scroll to a specific position - what it does, but only for the first ev...
