A handy library of common UI components that I use in my various projects. They may or may not be of any use to you. Highlights include:
BusyView, a protocol that can be implemented by
UIViews to display a
UIProgressViewover its other subviews to indicate that some action is being taken in the background
Controller, a protocol for
UIViewControllers that have a
Modelto offload UI and data model responsibilities that are normally in a view controller.
UIViewController+Alerts, a protocol that
UIViewControllers can implement to present alert controllers in a standard way.
