We stripped all the NSLog()’s out of our current app and the performance increase on the phone is very noticeable. I recommend you use something like a preprocessor macro you can #ifdef out.
If you’re having trouble figuring out where to set these preprocessor flags, do this:
- Select “Edit active target “<Your project name>”" from the Project menu.
- Set the configuration to the one you want it defined in.
- Scroll down till you see GCC 4.0 Preprocessing.
- Double click on “Preprocessor Macros”, add your stuff in there.
