iphone - VGA Output From ipad -
does apple support mirroring of ipad on tv can 1 give me idea
read this article:
there’s been lot of confusion how ipad vga adapter works. received mine today, , thought i’d try clear things little (and give code play with, if you’re ipad developer vga adapter of own).
the first thing understand adapter not mirror ipad screen. can’t plug ipad tv or monitor , see apps on big screen, steve jobs when he’s giving demo.
apps want support external display via adapter must explicitly so; developer has write code support it. there standard iphone os-supplied apis automatically right thing (such video playback via standard controllers), won’t see on external display unless app you’re using has taken steps put there. that’s “bad” (though surely not surprising) news.
the news it’s trivially easy support external display app if you’re developer; connected display shows uiscreen object. made sample project (which can download zip archive here) shows how it.
it’s nib 2 windows (one showing on ipad, , 1 showing on connected external display), , tiny bit of code make work.
