iPhone Leaks not showing trace

I am running my iPhone App on the simulator and looking for leaks using instruments. The problem is that the trace is no开发者_如何学Got sensible. It does't show any of my code or label any of the system calls. It's all just numbers.

Which SDK are you targeting? If you build for 3.0, I believe the symbols don't get displayed. Switching to 3.1 got the symbols displaying for me.

You need to run a Debug build for the traces to be symbolicated.
