Applications should not call -initWithLayer:. Its purpose of existence is so that if you have a CALayer subclass that has additional ivars that need copying, you can implement it and CoreAnimation can call it to do the right thing. The layers produced in this way are not expected to be useful as 'model' layers. > If I created maskL as a new mask layer ([CAShapeLayer layer]), and > initialized it to match shapeL (except for the fill), gradL was drawn as > expected. > > <http://stackoverflow.com/questions/4733966/applying-a-gradient-to-cashapelayer> > got me most of the way, but didn't extend to how to re-use the mask layer. Did you add the stroke shape layer as a sublayer of the gradient layer? If so, that may explain why you didn't get your stroke – the mask applies to a layer and all of its sublayers. As such, the shape layer would have at least partially masked the stroke (its possible Core Animation simply rejected rendering the shape layer entirely, as its path rendering emphasizes speed over accuracy). -- David Duncan _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
