NSLog Revisited

Logging is an essential tool when developing for iPhone. Keeping things simple and code readable is a major challenge when scattering logging code throughout your application. A few recent posts on the topic have provided some great solutions, but if you're like me sometimes a dead-simple solution is exactly what you need.

This is what I use:

// in Implementation.m
#define DLog NSLog

...

// I need to log something
DLog(@"something interesting happended: %@",what)

When I want to disable logging in that file, I simply change the #define as follows:

#define DLog // NSLog

That's all!
