but this error appear when this line is trying to execute: [recorder record];

i have no other AVAudioRecorder in project

In the Simulator? It's just a bug in the API. You can ignore it.

yes in simulator, but the program crashes and i can't test it...
i thought that the line [recorder record]; made it crashes, but sometimes crashes even before...
how can i know why the program crashes?
the console doesn't display anything interesting...
