@implementation ViewController

- (void)viewDidLoad {

[superviewDidLoad];

// Do any additional setup after loading the view, typically from a nib.

[selfcreatLayer];

_index =0;

}

//1、layer常用属性

- (void)layerProperty

{

//设置view圆角，当view是imageView时需要注意

// self.testView.layer.cornerRadius = 50;

// self.imageV.layer.cornerRadius = 50;

//// self.imageV.layer.masksToBounds = YES;

// self.imageV.clipsToBounds = YES;

//阴影的设置

self.testView.layer.shadowOpacity = 1;//透明度

self.testView.layer.shadowColor = [[UIColor redColor]CGColor];//阴影颜色

self.testView.layer.shadowOffset = CGSizeMake(60,10);//阴影的偏移

self.testView.layer.shadowRadius = 20;//阴影圆角

self.testView.layer.borderWidth = 10;//设置边框

self.testView.layer.borderColor = [[UIColor blueColor]CGColor];//设置边框颜色

}

//2、layer3D变换

- (void)layerTransform3D

{

[UIViewanimateWithDuration:1 animations:^{

// CATransform3D t = CATransform3DMakeTranslation(-100, 0, 0);

// CATransform3D t = CATransform3DTranslate(self.testView.layer.transform, -100, 0, 0);//多次移动的方式

CATransform3D t =CATransform3DRotate(self.imageV.layer.transform, M_PI_2, 1, 0,0);

// CATransform3D t = CATransform3DScale(self.imageV.layer.transform, 0.5, 2, 1);

// CATransform3D t = CATransform3DConcat(<#CATransform3D a#>, <#CATransform3D b#>);

self.imageV.layer.transform = t;

}];

}

//3、手动创建layer

- (void)creatLayer

{

self.cclayer = [CALayerlayer];

self.cclayer.backgroundColor = [UIColorcyanColor].CGColor;

self.cclayer.bounds =CGRectMake(0,0, 100,100);

//锚点（就是给layer的参照点，（0.0）点表示左上点（0.5，0.5）表示中心点）

self.cclayer.anchorPoint =CGPointMake(0,0);

//position（这个位置移动的是坐标原点）

//self.cclayer.position = CGPointMake(100, 100);

[self.view.layeraddSublayer:self.cclayer];

}

//4、隐式动画

- (void)layerHiddenAnimation

{

//layer隐式动画，只有非rootLayer才有隐式动画

[CATransactionbegin];

[CATransactionsetDisableActions:YES];//这个默认的就是yes要使用动画的时候不用写出来

[CATransactionsetAnimationDuration:2];

self.cclayer.position =CGPointMake(100,100);

[CATransactioncommit];//提交动画

}

//5、layerBaseAnimation

- (void)layerBaseAnimation

{

CABasicAnimation * baseAnimation = [CABasicAnimationanimation];

// baseAnimation.keyPath = @"position";

// baseAnimation.toValue = [NSValue valueWithCGPoint:CGPointMake(100, 100)];

baseAnimation.keyPath =@"transform.rotation";//使用系统的字符串来指定动画的类型

baseAnimation.toValue =@(M_PI_2);

baseAnimation.duration =1;

baseAnimation.removedOnCompletion =NO;//动画结束之后是否移除动画后的场景

baseAnimation.fillMode =kCAFillModeForwards;//当前动画场景的填充效果（这和上一句是配合着用的）

//以上只是创建了一个layerBaseAnimation动画

[self.imageV.layeraddAnimation:baseAnimation forKey:nil];//为imageV添加layerBaseAnimation

}

//6、关键帧动画

- (void)layerKeyFrameAnimation

{

// CAKeyframeAnimation * keyFrameAnim = [CAKeyframeAnimation animation];

// keyFrameAnim.keyPath = @"position";

// keyFrameAnim.duration = 3;

// NSValue * value0 = [NSValue valueWithCGPoint:CGPointMake(0, 0)];//因为默认的第一帧是没有动画效果的

// NSValue * value1 = [NSValue valueWithCGPoint:CGPointMake(100, 100)];

// NSValue * value2 = [NSValue valueWithCGPoint:CGPointMake(200, 100)];

// NSValue * value3 = [NSValue valueWithCGPoint:CGPointMake(200, 200)];

// keyFrameAnim.values = @[value0,value1,value2,value3];

// keyFrameAnim.removedOnCompletion = NO;

// keyFrameAnim.fillMode = kCAFillModeForwards;

// [self.cclayer addAnimation:keyFrameAnim forKey:nil];

//用贝塞尔曲线画一个路径

UIBezierPath * bezierPath = [UIBezierPathbezierPathWithOvalInRect:CGRectMake(30,100, 300,200)];

CAKeyframeAnimation * keyAnim = [CAKeyframeAnimation animation];

keyAnim.keyPath =@"position";

keyAnim.path = bezierPath.CGPath;

keyAnim.duration =2;

keyAnim.removedOnCompletion =NO;

keyAnim.fillMode =kCAFillModeForwards;

[self.cclayeraddAnimation:keyAnim forKey:nil];

}

//7、转场动画

- (void)transitionAnimaion

{

//第一

_index ++;

if (_index ==5) {

_index =1;

}

NSString * name = [NSStringstringWithFormat:@"%d.png",_index];

self.imageV.image = [UIImageimageNamed:name];

//第二

CATransition * transition = [CATransitionanimation];

//第三

transition.duration =1;

transition.type =@"cube";//可以用的类型如下：

transition.subtype =kCATransitionFromRight;

//第四

transition.removedOnCompletion =NO;

transition.fillMode =kCAFillModeForwards;

//第五

[self.imageV.layeraddAnimation:transition forKey:nil];

/*常用的转场效果（首字母小写）

typedef enum : NSUInteger {

Fade = 1, //淡入淡出

Push, //推挤

Reveal, //揭开

MoveIn, //覆盖

Cube, //立方体

SuckEffect, //吮吸

OglFlip, //翻转

RippleEffect, //波纹

PageCurl, //翻页

PageUnCurl, //反翻页

CameraIrisHollowOpen, //开镜头

CameraIrisHollowClose, //关镜头

CurlDown, //下翻页

CurlUp, //上翻页

FlipFromLeft, //左翻转

FlipFromRight, //右翻转

} AnimationType;

}

//8、动画组

- (void)layerAnimationGroup

{

CABasicAnimation * baseOne = [CABasicAnimationanimation];

baseOne.keyPath =@"position";

baseOne.toValue = [NSValuevalueWithCGPoint:CGPointMake(100,100)];

CABasicAnimation * baseTwo = [CABasicAnimationanimation];

baseTwo.keyPath =@"transform.rotation";

baseTwo.toValue =@(M_PI_2);

CAAnimationGroup * group = [CAAnimationGroupanimation];

group.duration =2;

group.animations =@[baseOne,baseTwo];

group.removedOnCompletion =NO;

group.fillMode =kCAFillModeForwards;

[self.cclayeraddAnimation:group forKey:nil];

}

- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event

{

// [self layerProperty];

// [self layerTransform3D];

// [self creatLayer];

// [self layerHiddenAnimation];

// [self layerBaseAnimation];

[selflayerKeyFrameAnimation];

// [self transitionAnimaion];

// [self layerAnimationGroup];
