Program 8.4 - avoid the dot notation

[dennishenley]

Is there a way to not use the dot notation for Program 8.4? Specifically the line:

Code: (Objective-C)

NSLog(@"Origin at (%i, %i)", myRectangle.origin.x, myRectangle.origin.y);

I tried using the [] notation like this:

Code: (Objective-C)

NSLog(@"Origin at (%i, %i)", [myRectangle [origin x]], [myRectangle [origin y]]);

This produces the error Use of undeclared identifier 'origin'. The dot notation does not produce an error and the program runs fine.

Any ideas?

You were nearly there, but not quite:

[[myRect origin] x]

Thanks. I understand now.

Is there a difference between using myRect.width and [myRect width] or are they both interchangeable?  Also when is it good practice to use one and not the other?
