reactivecocoa / reactiveanimation

Declarative animations using ReactiveCocoa signals

ReactiveAnimation

Declarative animations using ReactiveCocoa signals. See the Mac demo for an example of how the library works.

ReactiveAnimation is released under the MIT license.

Getting Started

To import the ReactiveAnimation framework, add ReactiveAnimation.xcodeproj as a subproject and add the appropriate framework target to your application.

Alternatively, you can use Carthage to build the framework for you.

reactiveanimation's Issues

What would be a good demo?

We have the MacDemo project already, and will want something for iOS, but what is a good demonstration of ReactiveAnimation?

Making a label fly around the screen is all well and good, but it's not particularly compelling. 😝

Any and all ideas welcome! 🙇

Objective-C API

None of this behavior is Swift-specific—it just happens to use Swift-only types. Let's add an Objective-C API for use too.

Animate view constraint sets

We can automatically animate the addition and removal of NSLayoutConstraints, by binding a signal or producer of [NSLayoutConstraint] to a view.

Dependency on Llamakit won't build without iOS Signing identity.

My environment is currently only setup with a mac developer program license (yes, I know things changed a few weeks ago regarding all that). Anyways, I noticed that even with "--configuration debug" suggested in Carthage/Carthage#281 the project won't build, and from reading the cartfile documentation ( https://github.com/Carthage/Carthage/blob/master/Documentation/Artifacts.md#cartfile ) I can't seem to find a way to specify a platform to ensure only Llamakit-mac is built.

Here's what the installation looks like:

Any idea on how to approach fixing this aside from just getting an iOS signing identity?

backgroundColor, center, transform

Additional animatable properties for UIView.

frameOrigin, frameSize, boundsOrigin, boundsSize

More animatable properties for NSView.

Animate NSLayoutConstraint.constant

We can wrap NSLayoutConstraint similarly to how we wrap views, and animate its constant property with signals.
