How to write this without dot notation

Question

Hi,

Can someone please help me write the following, without using dot notation:

self.bounds.size.width

I have tried [[[self bounds] size] width], but this results in an error. Any ideas?

Answer 1

You have brushed up against the ambiguity of dot syntax.

You want:

[self bounds].size.width

-bounds returns an NSRect C structure. Thus, you use traditional dots to access the items within.

Answer 2

To avoid mixed notation, I might prefer to use a local temporary C struct variable:

CGRect myBoundsRect = [ self bounds ];
foo = myBoundsRect.size.width;

That way the difference between object messages and C structure member accesses is explicitly separated.
