Hello...
NSPoint is also a struct.
For testing equality check out the functions that
are part of the Foundation framework, ie
NSEqualPoints, NSEqualRects, etc...
Hope that helps,
Louis
If I want to compare two NSRect pieces, I
thought I could do the following (modification
of the Sketch example program):
if (![_bounds.origin isEqualToPoint:_shadowBounds.origin])
where
NSRect _bounds;
NSRect _shadowBounds;
I get the following errors:
DocumentModel.subproj/SKTGraphic.m:74: warning:
invalid receiver type `untagged struct '
DocumentModel.subproj/SKTGraphic.m:74: warning:
cannot find method `-isEqualToPoint:'; return
type `id' assumed
DocumentModel.subproj/SKTGraphic.m:74: error: cannot convert to a pointer type
I know NSRect is a struct; however, NSPoint is
an object, so I should be using the message
format, right? I must be missing some subtle
pieceĀ
Thanks for any enlightenment!
Mark
