VIActonKit

VIAcitonKit is an extensible iOS animation library based on CoreAnimation.The actionkit's API was designed as simple as Cocos2d.

Features

• Simple use core animation for UIView and its subclass.
• Simple control the animation duration time.
• Support both actions at same time and sequeue actions.

Requirements

• Requires iOS6 or later
• Requires ARC

Usage

VIMove

Move from one point to another, and also you can desgn your own path.

+ (id)actionWithDuration:(CFTimeInterval)duration from:(CGPoint)fp to:(CGPoint)tp;
+ (id)actionWithDuration:(CFTimeInterval)duration path:(CGPathRef)path;

VIFade

Change view's opacity.

@interface VIFade : VIAction

+ (id)actionDuration:(CFTimeInterval)duration opacity:(float)op;

@end

@interface VIFadeIn : VIAction

+ (id)actionWithDuration:(CFTimeInterval)duration;

@end

@interface VIFadeOut : VIAction

+ (id)actionWithDuration:(CFTimeInterval)duration;
	
@end

VIScale

You can scale a view throw below methods.

+ (id)actionWithDuration:(CFTimeInterval)duration scale:(float)s;

+ (id)actionWithDuration:(CFTimeInterval)duration scaleX:(float)sx;

+ (id)actionWithDuration:(CFTimeInterval)duration scaleY:(float)sy;

VIRotate

Rotate view action.

@interface VIRotate : VIAction

/**
 *	rotate 旋转
 *
 *	@param	duration	时间
 *	@param	degree	角度 example:45 表示顺时针45°旋转 145 表示逆时针45°旋转
+ (id)actionWithDuration:(CFTimeInterval)duration degree:(float)degree;

VIDelayTime

Use this method:

[VIDelayTime actionWithDuration:duration],

You can control the animation's delay time.

VISequence

VIActionKit support sequence actions.

[demoView runAction:[SSSequence actions:
                     [SSMove actionWithDuration:4 from:testView.center to:CGPointMake(self.view.center.x, self.view.center.y - 100)],
                     [SSRotate actionWithDuration:4 degree:45],
                     [SSDelayTime actionWithDuration:4],
                     [SSScale actionWithDuration:4 scale:1.5],
                     nil]];

In above method,first action is move, then rotate, and then delaytime,scale at last.All thoes actions happened in sequence.
