Thanks for making something.
Good luck with your treatment, and welcome back to the land of development!

A much faster and simpler approach to do exactly what you have here is
CAShapeLayer. That will draw the path via OpenGL on your behalf without you
having to study OpenGL.
That said, copying and pasting from stack overflow or cocoa-dev list is never a

Hi John,
Try the layer's presentationLayer property. The presentationLayer is
the thing that is actually moving around and you should be able to get
'current' values from it (give or take a bit).

Hi Chilton,
There are a couple of examples of doing just that in the CA book
(disclaimer: I'm the author) showing how to animate views with
keyframe animations.
http://www.pragprog.com/titles/bdcora
The basic idea is to set the path for the keyframe animation and then
put that animation
Hi Chilton,
The animator does not commit its transaction until back in the event
loop so you won't see any animation until you return to the main event
loop.
You can of course override this but in the example below you are doing
the animation yourself so there is no reason for CA. i.e. tr

Hi Joeles,
The tiled layer does much of the work for you in terms of scrolling
and scaling.
I have an example on my blog;

description).
Good luck!

HI Sean,
One example would be if you have a method that calculates a value.
That value would not be in the DB so the compiled predicate (if it
would even compile) would not work because there is not column
corresponding to your calc'd value.
I think this is worth filing a bug against the
of you,

Hi Karl,
Have you tried the preferredFrameSize method? I have had success in
doing simple text sizing with this method ( by simple i mean that i've

Hi,
Sure...
Make 2 layers one is the 'background' the other is the button (think
the 'on/off' switch in time machine prefs pane)
when the user clicks the button you switch it to the on or off
position with buttonLayer.position = oppositePosition (a CGPoint)
make sense?

Hi Nate,
Glad it works!
You are correct that when you want to set up you own layer hierarchy
its best to leave that for awakeFromNib instead of setting the check
box. When you check that a view wants a layer in IB and then replace
it its just wasting creating that layer and such. Also I ha
Hi Nathan,
If you move your layer code into awakeFromNib you should have much
better results.
If you don't have layer backing turned on in the nib file the view
loading machinery turns off layer backing after initWithFrame: is
called.
