推荐答案

是的，有必要修复例如，您的背景为白色，并且在视图中添加了标签，然后将背景色设置为透明色。这将使您的图层混合。
但这不是必须计算的。
如果将标签颜色设置为与视图相同。
的滚动性能将提高很多。
您可以感觉到。

Yeah, It's necessary to fix the blended layers, For example: you background have a white color and you add a label in the view .and set background color clear color. This will make your layer blended. But this is unnecessary to calculate . If you set your label color same as your view. scrolling performance will improve a lot. You can feel it.
