TOValueTransition is a small and easy to use collection of classes for simple floating value "animations".
Use this library for time based interpolations between two values.

As TOValueTransition supports many easing functions, you might want to use it as animation library to easily animate your views.

Setup

CocoaPods
Simply add pod 'TOValueTransition', '~> 1.0.1' to your podfile.
For more information about CocoaPods and the podfile visit http://guides.cocoapods.org/

Manual
Add all files from /TOValueTransition to your project and target.

Usage

In the end there is only one important static method for TOValueTransition.

/**
 Creates a new instance of TOValueTransition and starts the Transition.
 @param baseValue Value to start from.
 @param targetValue Endvalue.
 @param duration Duration of the transition.
 @param easingId Identifier for the easing. Use one of the Identifier declared in TOEasing.h.
 @param progressHandler Block for progressUpdates.
 @param completedHandler Block for completed.
 @param cancelledHandler Block for cancelled.
 @see TOEasing.h
 @return The transitioning instance.
 */

TOValueTransition *transition = [TOValueTransition interpolateFrom:0.0 to:1.0 duration:3.4 easing:TOEasingElasticEaseOut progress:^(CGFloat currentValue) {

        //Do some update code here. 
        //This block will be called every 1/60 s.
        //e.g. update position of your view.

    } completed:^(CGFloat endValue) {

        //Finalize your transition here.
        //You might want to nil the transition.

    } cancelled:^(CGFloat cancelledValue) {

        //This block is called when you cancel the transition.
        //i.e. [transition cancel]
        //Again, you might want to nil the transition.

    }];

To cancel a transition you can call -(BOOL)cancel; This will stop the progress and will not call the completed block.

If you take a look at the Sample project (it’s an ios application) you can see how to use TOValueTransition to animate a white dot on the screen.
