    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
