USING THE SAMPLE: |
|
Build and run the sample on an iOS device that supports external displays |
such as iPad or iPhone 4. Plug in a display using the Apple iPad Dock |
Connector to VGA Adapter or Apple Component AV Cable. |
|
When an external display is detected, the app will show the available |
display resolutions. Select one from the picker and tap Set. |
|
Tap the Presentation Mode switch to toggle the contents shown on the |
external display. |
|
=========================================================================== |
PACKAGING LIST: |
|
main.m - Main entry point for this sample. |
|
ExternalDisplayAppDelegate.h/.m - The application's delegate that sets up |
the main window and navigation controller. |
|
ExternalDisplayViewController.h/.m - The main view controller. Also serves |
as a delegate for the presentation mode view controller to receive |
changes to the presence and resolution of an external display. |
|
Draws an image of a "1" on the external display if presentation |
mode is on or a "2" if presentation mode is off. |
|
PresoModeViewController.h/.m - Encapsulates all state and behavior related |
to detecting an external display being attached or removed, |
determining the available display modes (resolutions), and enabling |
the app's "presentation mode". "Presentation mode" simply indicates |
whether the app should show some of the content from the device |
display on the external display or show something different. |
|
When a new external display resolution is selected, creates a |
window and view of the new size and hands the window back to its |
delegate for drawing. |
