Is there a method that I can override in my custom classes so that when

      NSLog(@"%@", myObject)

is called, it will print the fields (or whatever I deem important) of my object? I guess I'm looking for the Objective-C equivalent of Java's toString().

- (NSString *)description

Here's an example implementation (thanks to grahamparks):

- (NSString *)description {
   return [NSString stringWithFormat: @"Photo: Name=%@ Author=%@", name, author];
}
