抖音点赞源码控制系统合作开发商业模式如是说

抖音前段时间愈来愈火，走到这儿此时此刻都能看见没人在刷抖音，是新媒体的代表者，新一代我科学研究了呵呵抖音雅雷的动画电影效用，别忘了也给我们撷取呵呵。

他们通过观察会辨认出雅雷的这时候会收敛出6个黄色的正方形，因此他们能借助萨克斯莱抛物线画出，间接上标识符：

CAShapeLayer*layer=[[CAShapeLayer alloc]init];

layer.position=_likeBefore.center;

layer.fillColor=[UIColor redColor].CGColor;

UIBezierPath*startPath=[UIBezierPath bezierPath];

[startPath moveToPoint:CGPointMake(-2,-30)];

[startPathaddLineToPoint:CGPointMake(2,-30)];

[startPathaddLineToPoint:CGPointMake(0,0)];

layer.path=startPath.CGPath;

[self.layer addSublayer:layer];

接着他们再给那个正方形加进动画电影，三个翻转动画电影刘天祺，三个方向动画电影从黑唇没，接着把这三个动画电影重新加入到组动画电影：

CAAnimationGroup*group=[[CAAnimationGroup alloc]init];

group.removedOnCompletion=NO;

group.timingFunction=[CAMediaTimingFunctionfunctionWithName:kCAMediaTimingFunctionEaseInEaseOut];

group.fillMode=kCAFillModeForwards;

group.duration=0.5;

CABasicAnimation*scaleAnim=[CABasicAnimation animationWithKeyPath: “transform.scale”];

scaleAnim.fromValue= (0.0);

scaleAnim.toValue= (1.0);

scaleAnim.duration=0.5*0.2f;

UIBezierPath*endPath=[UIBezierPath bezierPath];

[endPath moveToPoint:CGPointMake(-2,-length)];

[endPathaddLineToPoint:CGPointMake(2,-length)];

[endPathaddLineToPoint:CGPointMake(0,-length)];

CABasicAnimation*pathAnim=[CABasicAnimation animationWithKeyPath: “path”];

pathAnim.fromValue=(__bridge id)layer.path;

pathAnim.toValue=(__bridge id)endPath.CGPath;

pathAnim.beginTime=0.5*0.2f;

pathAnim.duration=0.5*0.8f;

[group setAnimations: [scaleAnim,pathAnim]];

[layer addAnimation:group forKey:nil];

这样三个正方形的完整的动画电影就完成了，接着他们借助for循环创建6个即可。

接着还有波纹慢慢扩大至心型图片圆周，再慢慢消失：

//创建背景

CAShapeLayer*layer=[[CAShapeLayer alloc]init];

layer.position=_likeBefore.center;

layer.fillColor=[UIColor clearColor].CGColor;

layer.strokeColor=_zanFillColor?_zanFillColor.CGColor:[UIColor redColor].CGColor;

layer.lineWidth=1;

//设置笔画方向

UIBezierPath*bPath=[UIBezierPathbezierPathWithArcCenter:CGPointMake(0,0)radius:_length startAngle:-M_PI_2 endAngle:-M_PI_2 M_PI*2 clockwise:YES];

layer.path=bPath.CGPath;

[self.layer addSublayer:layer];

//使用动画电影组来解决圆圈从小到大–
