Have you solved this problem? 这个问题，大家解决了吗？

I found that only loading from UIImage(named: "xxxx") has this problem, and loading with UIImage(contentsOfFIle: "xxx") is fine, it must be something that Apple handles by default internally 我发现只有从 UIImage(named: "xxxx") 加载的有该问题，使用 UIImage(contentsOfFIle: "xxx") 加载时是没问题的，一定是苹果内部默认处理了什么
