- The iDevice interface can rotate through three different orientations. True or false?
- How does an application communicate which rotation orientations it supports?
- What was the purpose of the
kDeg2Radconstant that we defined in the final exercise?
- False. There are four primary interface orientations: landscape right, landscape left, portrait, and upside-down portrait.
- As long as the the
supportedInterfaceOrientationsmethod is implemented in the view controller, the application identifies which of the four orientations it will operate in.
- We defined the
kDeg2Radconstant to give us an easy way of converting degrees to radians for the Core Graphics C function
