CABasicAnimation *shake = [CABasicAnimation animationWithKeyPath:@"transform.translation.x"];

//transform.translation.x 设定动画类型,方向,eg:旋转,平移,缩放, from,to

    shake.fromValue = from;   // 从哪里

    shake.toValue = to;   // 到哪里

    shake.byValue = by; // 偏移

    shake.speed = 8;  // 正常速度的 n

    shake.autoreverses = YES;//是否自动重复????

    shake.repeatCount = FLT_MAX;  //动画重复次数,eg:FLT_MAX 一直重复

    shake.duration = 1; // 持续时间, 越短,动画越快

    shake.fillMode = kCAFillModeForwards;

    shake.removedOnCompletion = NO; //结束时 是否删除, 按钮试验的,没看到区别

    

    [self.animationOverlay.layer addAnimation:shake forKey:@"shakeA"];

    self.animationOverlay.alpha = 0.4;

--view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"name.png"]];
--UIImage *image = [UIImage imageNamed:@"name.png"];

    view.layer.contents = (id) image.CGImage;

    // 如果需要背景透明加上下面这句

    view.layer.backgroundColor = [UIColor clearColor].CGColor;

2种效果相同,既frame小,只能显示一部分。  

view.layer.backgroundColor = [UIColor clearColor].CGColor;-- 》不能透明
