iOS adhoc displays black screen after launch

my iOS application displays black screen after splash screen.nothing happens after the splash screen and couldn't see any proper errors on debug utility.

I can build adhoc using flash builder and it's works fine but this problem occurs when I create ipa using dumped config file on command line(ant)

I'm using flex sdk 4.6 and AirSDK 15.0(overladed) iOS version 8.0 .my application includes few iOS native extensions.

I also tried installing flex sdk 4.13 with AIRSDK 15 but same thing happens.

mxmlc
mxmlc -load-config app-config.xml src/mobapp.mxml -output myapp.swf
