While working on an iOS project, I needed to display a single-selection widget so the user could select one option modally, kinda like how drop-downs are handled in Safari. I found a few examples on the web which tackled this problem, but none that could be easily reused. So I decided to create such a widget.
The result is UIPickerActionSheet, which is basically a UIPickerView inside a UIActionSheet. It also has a top bar with Done and Cancel buttons.
