Instruments! and a question about visual aids


A bit of geekgasm. I ran the Instruments program on top of the BMITime program and when we go to the cycles area showing the visual… I had a geekgasm.
This was totally cool. Do you recommend any particular books or web resources on using some of the other development tools like Instruments included in xcode?

Well probably getting a head of myself, but visual representation of objects and pointers is totally cool.

One other question, I find the object diagrams in the book quite helpful. What tools are you using to create these? Are there any that generate these directly from the code?

Thanks much,



Look in the developer documentation – I think there are good docs on Instruments there.

The diagrams were all created using OmniGraffle from OmniGroup. It is an excellent tool and well worth buying.


Thank you!
