抖動動畫如圖
實(shí)現(xiàn)上面效果代碼如下：
#define Angle2Radian(angle) ((angle) / 180.0 * M_PI)
CAKeyframeAnimation *anim = [CAKeyframeAnimation animationWithKeyPath:@"transform.rotation"];
anim.values = @[@(Angle2Radian(-3)), @(Angle2Radian(3)), @(Angle2Radian(-3))];
anim.duration = .2;
anim.repeatCount = MAXFLOAT;
// removedOnCompletion和fillMode一般是配合起來用的
// 添加layer層的核心動畫都會加上
anim.removedOnCompletion = NO;
anim.fillMode = kCAFillModeForwards;
[self.imgV.layer addAnimation:anim forKey:@"SHAKE"];
移除動畫代碼：
[self.imgV.layer removeAnimationForKey:@"SHAKE"];
