如何最小化来自imageView TVOS Focus CollectionView Swift的阴影

Question

我有一个UICollectionView和细胞.当我专注于细胞时,imageView adjustsImageWhenAncestorFocused.我的目标是让这个影子小得多.

Answer 1

在我的函数中，我不使用adjustsImageWhenAncestorFocused手动更改图像的大小：

override func didUpdateFocusInContext(context: UIFocusUpdateContext, withAnimationCoordinator coordinator: UIFocusAnimationCoordinator) {
        if (self.focused)
        {


                self.imageView.frame.size.width = self.imageView.frame.width+30
                self.imageView.frame.size.height = self.imageView.frame.height+30

                self.imageView.frame.origin.x = self.imageView.frame.origin.x - 15
                self.imageView.frame.origin.y = self.imageView.frame.origin.y - 15


        else
        {

                self.imageView.frame.size.width = self.imageView.frame.width-30
                self.imageView.frame.size.height = self.imageView.frame.height-30

                self.imageView.frame.origin.x = self.imageView.frame.origin.x + 15
                self.imageView.frame.origin.y = self.imageView.frame.origin.y + 15
           }
    }

这样你就不必处理阴影了。希望这可以帮助
