ios - View 在缩小时像素化

Question

我有一个由两个 UIImageView 组成的 UIView。它们是同心圆形状。当我像这样缩小这个 View 时:

CABasicAnimation *resizeAnimation = [CABasicAnimation animationWithKeyPath:@"transform.scale"];
    resizeAnimation.fromValue = [NSNumber numberWithDouble:1.0];
    resizeAnimation.toValue = [NSNumber numberWithDouble:0.25];
    resizeAnimation.fillMode = kCAFillModeForwards;
    resizeAnimation.removedOnCompletion = NO;

当缩小时，图像的边缘变得粗糙和像素化。我能做些什么来防止这种情况发生或至少将其最小化吗？

Answer 1

尝试将 ImageView 的层 minificationFilter 设置为 kCAFilterNearest 或 kCAFilterTrilinear
