Hello,

i have implement Access Music Library in my app.

i have change in info.plist

1) set Base sdk iPhone Device 3.0 and iPhone OS Deployment Target iphone 2.0 under Target info
2) set Header Search Paths "/usr/include/libxml2"
3) set Library Search Paths "lib"
4) set Build Active Architecture Only "YES"
5) add libxml2.2.dylib in Framework folder.


i have also update this things in Project info.
When I'm runing the app on the 3.0 beta 5 device, all is fine and the MPMediaQuery calls work.

But when I'm runing the app on my 2.2.1 device, I've got the following error:

dyld: Symbol not found: _OBJC_CLASS_$_MPMediaQuery
Referenced from: /var/mobile/Applications/EB544E0A-AE30-4DC8-BE9B-37B4F7C56EE2/CS2.app/CS2

Expected in: /System/Library/Frameworks/MediaPlayer.framework/MediaPlayer

anybody know above the problem?

Thank you
 
The media library framework is only available from 3.0 onwards.

hence why you are getting the error under 2.2.1
