NSLog and printing of an object

Question

I have a class and I want to setup what is printed when I call NSLog with that class. For example,

NSLog(@"%@",nonstandardObject);

How do I setup the object so it prints out what I'd want?

Answer 1

Override the -description method. It takes no parameters and returns an NSString that get's printf'd out.

There's another variant called -debugDescription (returns NSString, no parameters) that's used when po'ing the object from gdb.
