iPhone App Template w/ Multiple Button Types, Custom Alert & Action Sheet
by Amber Weinberg on Jul 05, 2010
// From Beginning iPhone 3 Development" book by Dave Mark and Jeff LaMarche
/* This app comes equipped with several buttons, sliders and fields.
The name button populates the alert
The slider changes the number to the left
The half buttons switches between 2 toggle switches and 1 large button. The button has been customized with extra code and implement's Apple's standard pretty button
The large button pops up an action sheet, then an alert.
All of these are already programmed for you, you just need to connect it to your interface!*/
