Where is my object allocation and memory leak in this iPhone/objective C code?
- by Spottswoode
Hello, I'm still a rookie when it comes to this programming gig and was wondering if someone could help me smooth out this code. Functionally, the code works great and does what I need it to do. But when I run the performance tool the allocation graph peaks, the CPU load is high, there's a leak(s), and I've also confirmed when running on my iPhone it seems noticeably slower then the rest of the components in my app.
I'd appreciate any advice/tips/help anyone could give me. :)
Thanks in advance!
