Error in SDK FilterDemo example


  • Subject: Error in SDK FilterDemo example
  • From: Michael Hopkins <email@hidden>

It was recently brought to our attention that there is a bug in the FilterDemo that may cause a crash in Logic. We have fixed this for the next release of the developer tools, but in the meantime, you can make the following changes to the FilterDemo code to fix this issue.

In AppleDemoFilter_UIView.m, add the following line in the dealloc
method (right before the free call):

	[[NSNotificationCenter defaultCenter] removeObserver: self];

We have tested this fix using the 1.5 SDK under Leopard in both Logic 8 and AU Lab 2.0.
