+2 A:

Use NSLog, e.g.:

NSLog(@"This is my NSArray: %@", [myNSArray description]);

that`s perfect, thanks :)

NSLog() already calls `-description` on the object. What really needs to be done is NSLog(myArray) or NSLog(@"mArray: %@", myArray);

NSLog(myArray) will bring up a warning in SDK 3.2. I'd advise going with a formatted string. I would also advise explicitly specifying the description method.

It is true, I always use a formatted string anyway :D. However I fail to see the point of explicitely calling description?

Issuing the description explicitly makes it absolutely clear, when reading the code, what NSLog will be showing, when dealing with types that do not offer `-description`. You don't have to use it, if you don't want to. I prefer to and would recommend this to others.

However, it's explicitly clear if you just read the documentation... http://developer.apple.com/mac/library/DOCUMENTATION/Cocoa/Conceptual/Strings/Articles/formatSpecifiers.html

Dave DeLong 2009-10-02 19:21:59

Whatever. Use NSLog(myArray) if you want to, as well. *shrug*
