使用 Core Animation 移动图像
知道为什么我在屏幕上移动的小图像变得模糊吗？ 在运动时，图像中的小细节变得不清楚，我认为这是一个问题。
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:@"position"];
Any idea why the small image that I move across the screen gets blurry?
While being in motion, the small details in the image become unclear and I think that it is a problem.

最终这被确定为液晶面板滞后。
Eventually this was identified as LCD panel lag.
