Just a quick question about this - I notice that you say to use a timer which I presume you say deliberately rather than using the automatic needsDisplay and recalculating during display.
The way I was thinking of doing it would have resulted in the recalculation of the path during the drawing, which in turn would have meant that I would want to change the frame/bounds during the drawing, which presumably would not be a good thing, right? Is this why you would say to use a timer? So presumably that means I would get the timer to fire frequently and then ask the presentation layer for the values for my animating points, and if they have changed, I recalculate my path, and update the frame if necessary, using a transaction which disables animation, and then calls setNeedsDisplay. Sorry to need to bother you for the clarification, but I just need to make sure I understand correctly.

With a requirement of 10.5, about all you can do is call -setNeedsDisplay from a timer to implement the animation yourself, unless your path can be animated well enough by just stretching/squeezing the layer. Either way your talking about drawing your path into a plain CALayer. -- David Duncan _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
