thank you looking at your video right now. however i noticed on your video your app reacts as soon you connect the vga cable, the app installed on my ipad (molecules downloaded from app store) does not react. there is no symbol for external screen appearing. the screen icon only appears if i start the app while the vga connector is connected.

The reason the App Store version doesn't respond to the connection of an external display is that the observers for the connection of the display are commented out (I didn't want to ship a half-working feature). Search the code for two commented-out lines that reference the notifications for connection and disconnection of the display. If you uncomment those, the application will respond to the external display.

For your other question, there's no support for automatic mirroring of views. You need to keep the views in sync between the two screens yourself.

one more question. if you

one more question. if you make a new UIView for the external View. is it possible to populate that externalView with the same content that should be displayed on your localView? like mirroring?

ps. your code and your help is awesome thanks. learning a lot here :)

thank you looking at your

The external display of 3-D

The external display of 3-D content does not work in the version of the source code I currently distribute. However, you can see how to enable external display of content using the code that I've stubbed out there (simply uncomment the two lines that add observation to the external screen connection / disconnection messages. Also, you can comment out the line in -displayOnExternalOrLocalScreen: for adding the 3-D view to the external window and instead add some other content to get it to display on the other screen.

I describe the process by which external display support can be enabled in your application in the iPad session of my advanced iPhone development course. The course notes for that class also provide a good reference for how to do this.
