Instruments, CPU time profiling, does't show Obj-C calls

I'm tr开发者_开发技巧ying to profile my code and use Instruments (iOS->CPU->Time Profiler) for it. I choose application and run the test. In Call Tree options I select 'Show Obj-C Only' check box but I don't see my application calls, just system/sdk libraries internal calls. The program built in debug mode.

How can I see my application's call?
