objective c - How do I do screen mirroring on iOS 4.3? -


apple's developer documentation said screen mirroring available on ios 4.3 without magic. 1 should use mirroredscreen property, it's readonly.

from apple's developers.apple.com:

mirroredscreen

the screen being mirrored external display.

...if mirroring supported , active, property contains screen object associated device’s main screen. represents screen being mirrored attached display. value of property nil when mirroring disabled, not supported, or no screen connected device.

to disable mirroring , use external display presenting unique content, create window , associate corresponding screen object.

it said how disable not how enable mirroring mode. how do it?

i want mirror app on projector without creating copies of views , update them when needed - looks bad.

also simulator crashes on using external screen emulation - okay?

on compatible devices, ios automatically mirror display when external screen attached.

i think ipad 2 support mirroring. can listen notification when external display connected.
