This project implements MonoTouch C# bindings for the excellent Facebook Pop. Check out their project page for a number of great examples and inspiration on how to make the most of the library.
The specific version linked is 1.0 (commit 2b8dbe17f8).
Clone this project, build and reference POP.dll like any other .NET library (add POP to your app's References).
You can also add POP.csproj to an existing solution and add to References then.
In your app:
using POP;
//...
POPSpringAnimation bounce = POPSpringAnimation.AnimationWithPropertyNamed (POPMutableAnimatableProperty.POPViewScaleXY);
bounce.SpringBounciness = 14;
bounce.ToValue = NSValue.FromSizeF (new SizeF (1.4f, 1.4f));
button.PopAddAnimation (bounce, "bounce.me");That's about all you need.
Note: The quickest way to get started it to check out the SampleApp. It demonstrates how to integrate Pop into your MonoTouch app.
A cool feature of Pop is that you can modify animations in flight. You can also modify a named animation at any point during the animation, even substituting a new / different type of animation (replace a Spring animation with a Decay etc).
When specifying [To/From] Values you need to wrap them in the appropriate native type, e.g. NSValue.FromType or NSNumber.FromFloat
A float
alphaAnimation.FromValue = NSNumber.FromFloat (0.4f);An object
NSValue fromValue = NSValue.FromSizeF (new SizeF (0.5f, 0.5f));
NSValue toValue = NSValue.FromSizeF (new SizeF (1, 1));The [To/From] Values expected by an animation depend on the property being animated. You can determine what's accepted/required by each by looking up the property in POPAnimatableProperty.mm.
These bindings are pretty simple. Bug reports and pull requests are always welcome.
- Document property -> value type mapping
- Add more samples (port the very cool popping)
- Where's POPAnimationDragCoefficient from POPAnimationExtras.h
