MFLTransformingDigit

####Beginnings of a fun animation project in UIBezierPaths

This is a highly complex animation library for showing numbers changing, be it a countdown, a clock, or a scoreboard. It now allows for any size frame with special affine transforms.

After creating it you can increment, decrement or set it directly to a digit.

Much more is planned in the future, but for now check out a video here. Note: This video is now out dated, check out the sample project for a better idea of capability.

###Initialize Types

The previous two initializers have been coalesced into one:

 - (id)initWithFrame:(CGRect)frame initialDigit:(NSInteger)initialDigit foldingStyle:(MFLFoldingStyle)foldingStyle;

Use the following initializer if you wish to copy a digit you already have:

 - (id)initWithFoldingDigit:(MFLTransformingDigit *)digit;

###Editable Properties

The following properties are available to customize the style and animation of the digits.

####Style Properties

 @property (nonatomic) CGColorRef strokeColor;
 @property (nonatomic) CGFloat lineThickness;
 @property CGFloat transformDuration;

####Animation Values

 @property NSString *calculationMode;
 @property id timingFunction;
 @property MFLAnimationStyle animationStyle;

####Extra Animations

 @property MFLRotateAnimationStyle rotate3DStyle;
 @property MFLScaleAnimationStyle scaleStyle;
 @property BOOL shouldRotateIn2D;
 @property BOOL shouldAnimationNewSuperview;

###Available Functions

 - (void)animateToDigit:(NSInteger)digit;
 - (void)animateToDigit:(NSInteger)digit completion:(void (^)(BOOL))completion;
 
 - (void)decrement;
 - (void)decrementWithCompletion:(void (^)(BOOL))completion;
 
 - (void)increment;
 - (void)incrementWithCompletion:(void (^)(BOOL))completion;

MFLTransformingScoreBoard

The Scoreboard is a new addition built by stringing together a dynamic amount of MFLTransformingDigits.

You can use it in IB, or just plain initWithFrame, but if you want a bit more control over the style, you can use these:

 - (id)initWithBaseDigit:(MFLTransformingDigit *)digit forFrame:(CGRect)frame;

 - (id)initWithBaseDigit:(MFLTransformingDigit *)digit andValue:(NSInteger)value forFrame:(CGRect)frame;

The idea is to create an MFLTransformingDigit with the style you want to use, and then initialize your scoreboard with it. Resetting this digit later will update the look of your Scoreboard.

After that, you have three basic methods:

 - (void)setToValue:(NSInteger)value;

 - (void)decrementByValue:(NSInteger)value;

 - (void)incrementByValue:(NSInteger)value;

The methods come in flavors with completion blocks and durations for finer grained control. If at any time you want to stop the animation call:

 - (void)stopAnimation;

###License

Feel free to do whatever you'd like with this codebase privately, I've put it here as an example of some fun CAShapeLayer/UIBezierPath drawing examples. However, if you'd like to use the app in a commercial application, I'd appreciate it if you would pick up a commercial license from BinPress for 40$ or contact me to work something else out.

###Future Plans

Eventually this will hold multiple fonts, but is currently based on Futura.

A clock is still in the works, but the current plan is to implement a scoreboard of sorts which string together multiple MFLTransformingDigits

####Credit due. This animation is inspired by the "Timely" Android App, and this writeup describing it's bezier math.

Scoreboard is based a bit on JDFlipNumberView's implementation of target animation
