ios - 视图缩小时像素化

Question

我有一个由两个UIImageView组成的UIView。它们是同心圆形状。当我规模这个观点下是这样的：当缩小

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

图像的边缘变得粗糙和像素化。有什么我可以做，以防止这种情况，或至少将其最小化？

Answer 1

尝试将图像视图的图层缩小滤镜设置为kCAFilterNearest或kCAFilterTrilinear
