1. xcode log 問題
新建立工程，都會打印一堆莫名其妙看不懂的Log

屏蔽的方法如下:
Xcode8里邊 Edit Scheme-> Run -> Arguments, 在Environment Variables里邊添加
OS_ACTIVITY_MODE ＝ Disable
這樣設置只能對單個項目有效。 新創(chuàng)建的項目是無效的，希望 apple 在后續(xù)的 xcode 的 版本中修復這個 bug

2. 不能注釋的問題
因為蘋果解決xcode ghost，把插件屏蔽了。
解決方法
打開終端，命令運行： sudo /usr/libexec/xpccachectl
然后必須重啟電腦后生效
Xcode8內置了開啟注釋的功能，位置在這里：
