CABasicAnimation期间的运动模糊

Question

我有这个简单的动画，可以将图像从一个点移动到另一个点：

    CABasicAnimation *anim = [CABasicAnimation animationWithKeyPath:@"position"];
    anim.fromValue  = [NSValue valueWithCGPoint:CGPointMake(px2.x, px2.y)];
    anim.toValue    = [NSValue valueWithCGPoint:CGPointMake(P3x, P3y)];
    anim.duration   = 1.5f;
    anim.repeatCount =1;
    anim.removedOnCompletion = YES;
    anim.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseIn];
    [LA  addAnimation:anim forKey:@"positionTest"];

问题是图像在运动时变得模糊，运动不是很快。 有没有办法减少这种运动模糊？

Answer 1

如果你在动画期间拍摄截图，它肯定会模糊吗？模糊像素化模糊还是更像软高斯模糊？

尝试设置view.layer.shouldRasterize = yes和layer.rasterizationScale = UIScreen.mainScreen.scale;
