Hi, I've got a custom image browser view with IKImageBrowserCell subclass where I've added a little sign graphic that I would like to animate on some occasions. It's kind of like the "i" sign on Panic's Coda Sites view (which I'm guessing is an ImageBrowserView customized.. right?). On Coda's sites view, if you hover on a project the l...

(and a few hundred more) These CALayer instances represent small square dots in a dot matrix display for an fast countdown clock. I'm updating their backgroundColor as often per second as possible. Actually what I want is 60 times...
I have a bunch of identical CALayers that I want to reuse. Often, a few of them should disappear, and then get reused in another position within the same superlayer (half a second or so later). What is the best way (performance-wise) to keep them while they have disappeared from the screen? setHidden:YES, or setOpacity:0, or removeFromS...
I have a custom CALayer (say CircleLayer), containing custom properties (radius and tint). The layer renders itself in its drawInContext: method. - (void)drawInContext:(CGContextRef)ctx { NSLog(@"Drawing layer, tint is %@, radius is %@", self.tint, self.radius); CGPoint centerPoint = CGPointMake(CGRectGetWidth(self.bounds)/2, C...

My view draws in its CALayer via the drawLayer: inContext: delegate callback. This layer has a CATiledLayer-derived sublayer, which does its own drawing in an overridden drawInContext: method. Both layers are ...
