title: Log nothing with DDASLLogger in IOS7 on a real device
body: <p>Using <a href="https://github.com/robbiehanson/CocoaLumberjack" rel="nofollow">Lumberjack</a> in IOS7 on an ipod5, I Added a DDASLLogger to DDLog, and logged something. And used "asl_search" to get logs, but got nothing. When I did it on ios7 iphone simulator, I got what I exactly logged. Is it a bug of DDASLLogger?</p>
