CKShapeView
CKShapeView is a UIView subclass that is backed by a CAShapeLayer.
In other words, it is a view that is capable of rendering an arbitrary CGPath.
It is completely configurable and animatable, so you can have custom drawn views without needing to subclass.
CKShapeView has all of the properties of CAShapeLayer, with the addition of a hitTestUsingPath property that allows you to hit test using the path instead of the view's bounds.
Example Usage
CKShapeView *pieView = [[CKShapeView alloc] initWithFrame:CGRectMake(0, 0, 100, 100)];
CGFloat width = CGRectGetWidth(pieView.bounds);
pieView.path = [UIBezierPath bezierPathWithOvalInRect:CGRectInset(pieView.bounds, width/4, width/4)];
pieView.lineWidth = width/2;
pieView.fillColor = nil;
pieView.strokeColor = [UIColor blackColor];
[self.view addSubview:pieView];
UIViewAnimationOptions options = UIViewAnimationOptionAutoreverse | UIViewAnimationOptionRepeat;
[UIView animateWithDuration:1.0f delay:0.0f options:options animations:^{
pieView.strokeEnd = 0.0f;
} completion:nil];
