出现的问题

运行的时候，控制台首先会提示

: calling -display has no effect.

之后在创建SKLabelNode的过程中，出现了

CUICatalog: Invalid Request: requesting subtype without specifying idiom

之后就是

Received memory warning.

最后出现

Message from debugger: Terminated due to memory issue

程序退出

排查原因

查找资料的路径是

百度->必应->stackoverflow->forums.developer.apple.com

目前的结论

根据资料的查找，得出的结论是…..

这是XCode7.2的一个BUG

简直了…….
