I have the following CALayer: CAGradientLayer *gradient = [CAGradientLayer layer]; gradient.frame = CGRectMake(8, 57, 296, 30); gradient.cornerRadius = 3.0f; gradient.colors = [NSArray arrayWithObjects:(id)[RGB(130, 0, 140) CGColor], (id)[RGB(108, 0, 120) CGColor], nil]; [self.layer insertSublayer:gradient atIndex:0]; I'd like to add an inner shadow effect to it, but I am not quite sure how to do this. I suppose I would be required to draw in drawRect, however this would add the layer on top of other UIView objects, since it's supposed to be a bar behind some buttons, so I am at a loss as to what to do? I could add another layer, but again, not sure how to achieve the inner shadow effect (like this: http://sublimeorange.com/uploads/2009/09/innershadow.png ) Help appreciated... Source: Tips4all

I have a CALayer subclass, MyLayer, that has a NSInteger property called myInt. I'd really like to animate this property via CABasicAnimation, but it seems CABasicAnimation only works on so-called "animatable" properties (bounds, position, etc). Is there something I can override to make my custom myInt property animatable?
