Shapes is a set of wrappers around CAShapeLayer and UIBezierPath, that allows drawing and animating geometrically shaped views on iOS. Read more about it on the blog: http://mlsdev.com/blog/23

Shaped views

DTShapeView is a UIView subclass, that is backed by CAShapeLayer instead of CALayer. It provides API for changing CAShapeLayer path, fill and stroke colors and other layer properties, basically allowing UIView to behave like geometric shape.

All DTShapeView properties are automatically converted to CAShapeLayer properties or use CAShapeLayer properties directly. You can use whatever style you like, but we recommend using UIBezierPath and DTShapeView properties, because this allows you to completely bypass CoreFoundation objects. It also allows you to use CoreGraphics API instead of QuartzCore.

DTShapeView fully supports both explicit and implicit animation and hit testing inside it's path.

Progress views

DTProgressView is a DTShapeView subclass, that allow animating progress views of any shape. DTProgressView uses DTShapeView path as track.

By default, DTProgressView fills entire view bounds, filling view from left to right. And all you need to create a progress view, is drop it onto your view, set strokeColor and your progress view is ready!

self.simpleProgressView.strokeColor = [UIColor greenColor];

Whenever your progress changes, simply call

[self.simpleProgressView setProgress:progress animated:YES];

And progress change will be animated. DTProgressView supports any geometric shape UIBezierPath can define, and allows customizing animation duration and animation function.

Dimming views

DTDimmingView allows dimming part of the view, by "cutting" visible path from it. By default, dimming path contains entire UIView bounds. Create UIBezierPath, that describes, which part of the view should be visible, and set it on DTDimmingView instance to allow content to be seen.

    UIBezierPath * roundedPath = [UIBezierPath bezierPathWithOvalInRect:CGRectInset(self.view.bounds, 100, 100)];
    self.dimmingDynamicView.visiblePath = roundedPath;

Shaped buttons

DTShapeButton is a UIButton, that has DTShapedView added as a subview. As a result, it allows manipulating UIButton shape and visual appearance by changing DTShapedView properties. By default, button shape is a rectangle with UIButton bounds set as it's frame. For example, drawing initial state of AppStore download button looks like this:

self.downloadButton.shape.path = [UIBezierPath bezierPathWithRoundedRect:self.downloadButton.bounds cornerRadius:5.0f];
