CoreAnimation

1.CABasicAnimation

// position 
CABasicAnimation *ba = [CABasicAnimation animationWithKeyPath:@"position"];

// bounds
CABasicAnimation *ba = [CABasicAnimation animationWithKeyPath:@"bounds.size"];

// opacity
CABasicAnimation *ba = [CABasicAnimation animationWithKeyPath:@"opacity"];

// backgroundColor
// 景色渐变一定用CGColor
CABasicAnimation *ba = [CABasicAnimation animationWithKeyPath:@"backgroundColor"];

// transform.scale
// 以下缩放是中心缩放，若需要自定义缩放点需要设置锚点: [self.firstView.layer setAnchorPoint:CGPointMake(0, 0)];
// 一般，锚点位于图层中心{0.5，0.5},其度量是以单位方形而不是点为参照，无论图层有多大，右下角的坐标都是{1.0,1.0}
CABasicAnimation *ba = [CABasicAnimation animationWithKeyPath:@"transform.scale"];

// transform.rotation
CABasicAnimation *ba = [CABasicAnimation animationWithKeyPath:@"transform.rotation.y"]; // x ,y ,z 默认是z

// transform.translation
CABasicAnimation *ba = [CABasicAnimation animationWithKeyPath:@"transform.translation.x"]; // x ,y ,z 默认是x

// cornerRadius
 CABasicAnimation *ba = [CABasicAnimation animationWithKeyPath:@"cornerRadius"];

// borderWidth
CABasicAnimation *ba = [CABasicAnimation animationWithKeyPath:@"borderWidth"];

以position为例

// position
- (void)postionAnimation {
    CABasicAnimation *ba = [CABasicAnimation animationWithKeyPath:@"position"];
    ba.toValue = [NSValue valueWithCGPoint:self.firstView.center];
    ba.duration = 0.8;
    ba.delegate = self;
    ba.removedOnCompletion = NO; // 动画结束后是否回到原状态，默YES.若为NO，则 fillMode 须为 kCAFillModeForwards
    ba.fillMode = kCAFillModeBackwards;
    ba.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseOut]; // 动画的时间节奏控制
    [self.secondView.layer addAnimation:ba forKey:@"position"];
}

2.CAKeyframeAnimation

- (void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];

    [self valuesAnimation];
}

- (void)valuesAnimation {
    CAKeyframeAnimation *kf = [CAKeyframeAnimation animationWithKeyPath:@"position"];
    kf.fillMode = kCAFillModeForwards;
    kf.removedOnCompletion = NO;
    kf.duration = 3;
    kf.repeatCount = 0;
    NSValue *value1 = [NSValue valueWithCGPoint:CGPointMake(0, 120)];
    NSValue *value2 = [NSValue valueWithCGPoint:CGPointMake(190, 20)];
    NSValue *value3 = [NSValue valueWithCGPoint:CGPointMake(20, 300)];
    NSValue *value4 = [NSValue valueWithCGPoint:CGPointMake(300, 150)];
    kf.values = @[value1,value2,value3,value4];

    [self.firstView.layer addAnimation:kf forKey:@"valuesKeyframe"];
}

- (void)pathAnimation {
    CAKeyframeAnimation *kf = [CAKeyframeAnimation animationWithKeyPath:@"position"];
    kf.duration = 3.0f;
    kf.removedOnCompletion = NO;
    kf.fillMode = kCAFillModeForwards;
    kf.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseOut];

    CGMutablePathRef path = CGPathCreateMutable();
    CGPathAddEllipseInRect(path, NULL, CGRectMake(0, 0, 370, 300));

    kf.path = path;
    CGPathRelease(path);

    [self.firstView.layer addAnimation:kf forKey:@"pathKeyframe"];
}

3.CATransition
/***********type:动画过渡类型***********************

        kCATransitionFade 交叉淡化过渡
        kCATransitionMoveIn 新视图移到旧视图上面
        kCATransitionPush 新视图把旧视图推出去
        kCATransitionReveal 将旧视图移开,显示下面的新视图

        kCATransitionCube 立方体翻滚效果
        kCATransitionOglFlip 上下左右翻转效果
        kCATransitionSuckEffect 收缩效果，如一块布被抽走
        kCATransitionRippleEffect 水滴效果
        kCATransitionPageCurl 向上翻页效果
        kCATransitionPageUnCurl 向下翻页效果
        kCATransitionCameraIrisHollowOpen 相机镜头打开效果
        kCATransitionCameraIrisHollowClos 相机镜头关闭效果

************************************************************/

/***********subType:动画过渡方向***********************

        kCATransitionFromRight 从右边
        kCATransitionFromLeft 从左边
        kCATransitionFromTop 从顶部
        kCATransitionFromBottom 从底部

*************************************************************/
以cameraIrisHollowOpen为例

 - (void)cameraIrisHollowTransition {
    CATransition *t = [CATransition animation];
    t.type = @"cameraIrisHollowOpen";
//    t.type = @"cameraIrisHollowClos";
    t.subtype = kCATransitionFromLeft;
    t.duration = 1.5;
    self.firstView.backgroundColor = [UIColor colorWithRed:0.2 green:0.3 blue:0.6 alpha:1];
    [self.firstView.layer addAnimation:t forKey:@"pageCurlTransition"];
}

4.CASpringAnimation 继承自CABasicAnimation

/**
 *  @author Jack Lee, 16-05-17 22:05:53
 *
 *  @brief after iOS9.0
 */
- (void)springAnimation {
    CASpringAnimation *spring = [CASpringAnimation animationWithKeyPath:@"bounds.size"];
    spring.mass = 10;  // 质量，影响图层运动时的弹簧惯性，质量越大，弹簧拉伸和压缩的幅度越大
    spring.stiffness = 5000; // 刚度系数(劲度系数/弹性系数)，刚度系数越大，形变产生的力就越大，运动越快
    spring.damping = 100; // 阻尼系数，阻止弹簧伸缩的系数，阻尼系数越大，停止越快
    spring.initialVelocity = 5; // 初始速率，动画视图的初始速度大小;速率为正数时，速度方向与运动方向一致，速率为负数时，速度方向与运动方向相反
    spring.duration = spring.settlingDuration; // 结算时间 返回弹簧动画到停止时的估算时间，根据当前的动画参数估算，通常弹簧动画的时间使用结算时间比较准确
    spring.toValue =[NSValue valueWithCGSize:self.firstView.bounds.size];
    spring.removedOnCompletion = NO;
    spring.fillMode = kCAFillModeForwards;
    [self.secondView.layer addAnimation:spring forKey:@"spring"];
}

5.CAAnimationGroup

- (void)groupAnimation {
    CABasicAnimation *p = [CABasicAnimation animationWithKeyPath:@"position"];
    p.toValue = [NSValue valueWithCGPoint:self.firstView.center];

    CABasicAnimation *o = [CABasicAnimation animationWithKeyPath:@"opacity"];
    o.toValue = @(0.2);

    CABasicAnimation *b = [CABasicAnimation animationWithKeyPath:@"bounds.size"];
    b.toValue = [NSValue valueWithCGSize:self.firstView.bounds.size];

    CAAnimationGroup *g = [CAAnimationGroup animation];
    g.animations = @[p,o,b];
    g.duration = 0.8;
    g.removedOnCompletion = NO;
    g.fillMode = kCAFillModeForwards;
    g.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseOut];

    [self.secondView.layer addAnimation:g forKey:@"groupAnimation"];
}
