Finding the line of memory leak in Instruments

问题

I am able to find the memory leak and able to press the arrow to go to history of the memory leak item. But when i double-click any of them, it doesn't show the line it is causing the memory leak.

The image is like this:

What am i doing wrong? Need some guidance... Thanks..

I had trouble finding it at first too. Here's how:

1. Select the Leaks instrument (obviously).
2. Show the "Extended Detail" Pane by clicking the Icon in the toolbar that toggles it from the right.
3. Select Your leaked item from the list.
4. Double Click on the entry there you see your Application Name and/or one of your Classes, which has a User Icon next to it to take you to the problematic code. (There can be more than one)

Double clicking that (4), will take you directly to the file, and line of code in question:
