Question

I am new to Objective-C and iPhone Development and while I am familiar with pointers to an extent, I often see code that includes things like this:

- (BOOL)application:(UIApplication *)application...

When you have the * inside the ( ) like that what does that mean?

Thanks!

Answer 1

It’s a instance method (- means instance method, + is class method) that returns BOOL named application and it takes an argument of a pointer to UIApplication named application.

The (UIApplication *) just means a pointer to a UIApplication class.
