BabyPigAnimation

从简单的基础动画到复杂的组动画，原理一目了然。最后再加上几个常见动画，举一反三。

使用

基础动画

//位移-(void)makePositionAnimation{    CABasicAnimation *animation = [CABasicAnimation animationWithKeyPath:@"position"];    animation.fromValue = [NSValue valueWithCGPoint:CGPointMake(50, SCREEN_HEIGHT/2-75)];    animation.toValue = [NSValue valueWithCGPoint:CGPointMake(SCREEN_WIDTH-50, SCREEN_HEIGHT/2-75)];    animation.duration = 1.0f;    //animation.fillMode = kCAFillModeForwards;    //animation.removedOnCompletion = NO;    [self.babyView.layer addAnimation:animation forKey:@"positionAnimation"];}

关键帧动画

CAKeyframeAnimation *animation = [CAKeyframeAnimation animationWithKeyPath:@"position"];NSValue *value_0 = [NSValue valueWithCGPoint:CGPointMake(50, SCREEN_HEIGHT/2-50)];NSValue *value_1 = [NSValue valueWithCGPoint:CGPointMake(SCREEN_WIDTH/3, SCREEN_HEIGHT/2-50)];NSValue *value_2 = [NSValue valueWithCGPoint:CGPointMake(SCREEN_WIDTH/3, SCREEN_HEIGHT/2+50)];NSValue *value_3 = [NSValue valueWithCGPoint:CGPointMake(SCREEN_WIDTH*2/3, SCREEN_HEIGHT/2+50)];NSValue *value_4 = [NSValue valueWithCGPoint:CGPointMake(SCREEN_WIDTH*2/3, SCREEN_HEIGHT/2-50)];NSValue *value_5 = [NSValue valueWithCGPoint:CGPointMake(SCREEN_WIDTH-50, SCREEN_HEIGHT/2-50)];animation.values = [NSArray arrayWithObjects:value_0,value_1,value_2,value_3,value_4,value_5, nil];animation.duration = 2.0f;[self.babyView.layer addAnimation:animation forKey:@"keyFrameAnimation"];

组动画

CAKeyframeAnimation *positionAni = [CAKeyframeAnimation animationWithKeyPath:@"position"];NSValue *value_0 = [NSValue valueWithCGPoint:CGPointMake(50, SCREEN_HEIGHT/2-50)];NSValue *value_1 = [NSValue valueWithCGPoint:CGPointMake(SCREEN_WIDTH/3, SCREEN_HEIGHT/2-50)];NSValue *value_2 = [NSValue valueWithCGPoint:CGPointMake(SCREEN_WIDTH/3, SCREEN_HEIGHT/2+50)];NSValue *value_3 = [NSValue valueWithCGPoint:CGPointMake(SCREEN_WIDTH*2/3, SCREEN_HEIGHT/2+50)];NSValue *value_4 = [NSValue valueWithCGPoint:CGPointMake(SCREEN_WIDTH*2/3, SCREEN_HEIGHT/2-50)];NSValue *value_5 = [NSValue valueWithCGPoint:CGPointMake(SCREEN_WIDTH-50, SCREEN_HEIGHT/2-50)];positionAni.values = [NSArray arrayWithObjects:value_0,value_1,value_2,value_3,value_4,value_5, nil];CABasicAnimation *scaleAni = [CABasicAnimation animationWithKeyPath:@"transform.scale"];scaleAni.fromValue = [NSNumber numberWithFloat:0.8f];scaleAni.toValue = [NSNumber numberWithFloat:2.0f];    CABasicAnimation *rotateAni = [CABasicAnimation animationWithKeyPath:@"transform.rotation"];rotateAni.toValue = [NSNumber numberWithFloat:M_PI*4];    CAAnimationGroup *groupAni = [CAAnimationGroup animation];groupAni.animations = [NSArray arrayWithObjects:positionAni,scaleAni,rotateAni, nil];groupAni.duration = 4.0f;[self.babyView.layer addAnimation:groupAni forKey:@"groupAnimation"];

过渡动画

CATransition *transitionAni = [CATransition animation];transitionAni.type = kCATransitionMoveIn;transitionAni.subtype = kCATransitionFromRight;transitionAni.duration = 1.0f;[self.babyView.layer addAnimation:transitionAni forKey:@"moveInAnimation"];
