I've noticed a major drop in fps in my sprite kit game having upgraded from iOS 8.4 to iOS 9. Has anyone else encountered this?
我的纹理图集仍然埋在.atlas文件中.我尝试使用资产目录纹理图集功能作为实验，但性能却更差.
My texture atlases are still buried away in .atlas files. I've tried to use the asset catalog texture atlas functionality as an experiment and that gives even worse performance.
推荐答案
您尝试过吗?
skView.ignoresSiblingOrder = YES;

You will probably have to set some zValues explicitly after the change, but the number of draw calls will hopefully be reduced. You can BTW display the number of draw calls by this line:
skView.showsDrawCount = YES;
