Program 8.4 - NSLogs

[MCaEd]

Hello,
I don't understand how to interpret these two NSLogs:

Code: (Objective-C)

NSLog (@"Rectangle w = %i, h = %i", myRect.width, myRect.height);
NSLog (@"Origin at (%i, %i)", myRect.origin.x, myRect.origin.y);

What does myRect.width mean? Using the knowledge of dot operator - set width of myRect?!
Also, how do you explain myRect.origin.x?
I've read once again about dot operator on pages 129-130 but don't see it answering.
Thanks in advance

myRect.width is the same as [myRect width]

myRect.origin.x is the same as [[myRect origin] x]

Cheers,

However, width and x are not methods but rather instant variables, so how can you use them that way?

[skochan]

Yes, they are methods you wrote or are synthesized.  They are getter methods that correspond to the instance variable names.

Cheers,

Oh, yes, they are. I've just read the code again. Thank you for the clarification, Steve!
