MMTweenAnimation

MMTweenAnimation is a extension of POP(from facebook) custom animation. Inspired by tweaner(https://code.google.com/p/tweaner), MMTweanerAnimation provide 10 types of custom animation while using POP.

Animation functions are based on Easing functions

Easing functions specify the rate of change of a parameter over time and allow you to apply custom mathematical formulas to your animations.

Installation

The preferred way of installation is via CocoaPods. Just add

pod 'MMTweenAnimation'

and run pod install. It will install the most recent version of MMTweenAnimation.

If you would like to use the latest code of MMTweenAnimation use:

pod 'MMTweenAnimation', :head

Type

There are 10 concrete animation types:

Back	Bounce	Circ	Cubic	Elastic

Expo	Quad	Quart	Quint	Sine

Usage

To apply a MMTweenAnimation, you must configure it by:

@property (nonatomic, copy)   MMTweenAnimationBlock  animationBlock;

@property (nonatomic, assign) NSArray *fromValue;
@property (nonatomic, assign) NSArray *toValue;
@property (nonatomic, assign) double duration;  //default: 0.3

@property (nonatomic, assign) MMTweenFunctionType functionType; //default: MMTweenFunctionBounce
@property (nonatomic, assign) MMTweenEasingType   easingType;   //default: MMTweenEasingOut

for example:

MMTweenAnimation *anim = [MMTweenAnimation animation];
anim.functionType   = MMTweenFunctionBounce;
anim.easingType     = MMTweenEasingOut;
anim.duration       = 2.0f;
anim.fromValue      = @[@0];
anim.toValue        = @[@200];
anim.animationBlock = ^(double c,double d,NSArray *v,id target,MMTweenAnimation *animation)
{
    //c: current time, from the beginning of animation
    //d: duration, always bigger than c
    //v: value, after the change at current time

    double value = [v[0] doubleValue];
    UIView *t = (UIView*)target;
    t.center = CGPointMake(t.x, value);
};

[targetView pop_addAnimation:anim forKey:@"center.y"];

Changelog

v1.1 you can animate several values at the same time

typedef void(^MMTweenAnimationBlock)(double c,   
                                     double d,  
                                     NSArray *v, // change to array
                                     id target,
                                     MMTweenAnimation *animation
                                     );

@property (nonatomic, strong) NSArray *fromValue;	// change to array
@property (nonatomic, strong) NSArray *toValue;		// change to array

v1.0 you can custom or simply use it by

@interface MMTweenAnimation : POPCustomAnimation

@property (nonatomic, copy)   MMTweenAnimationBlock  animationBlock;

@property (nonatomic, assign) double fromValue;
@property (nonatomic, assign) double toValue;
@property (nonatomic, assign) double duration;

@property (nonatomic, assign) MMTweenFunctionType functionType;
@property (nonatomic, assign) MMTweenEasingType   easingType;

+ (instancetype)animation;
