Basic Objective-C syntax: “%@”?

Question

I\'m working through the Stanford iPhone podcasts and have some basic questions.

The first: why is there no easy string concatenation? (or am I just missing it?)

Answer 1

Also, %@ is fairly versatile, as it actually inserts the result of the argument's description method into the result string. For NSString, that's the string's value, other classes can provide useful overrides. Similar to toString in Java, for example.
