1.多行注釋問題:

• 發(fā)現(xiàn)升級Xcode8以后 "command + /" 不好使了,身為一個(gè)程序員這樣的問題不解決?不能夠啊...解決辦法 如下:

   sudo /usr/libexec/xpccachectl

• PS:然后必須重啟電腦后生效

2.控制臺打印一堆問題:

• 升級Xcode8以后控制臺會打印許多網(wǎng)絡(luò)相關(guān)的日志:

• 解決辦法:選擇"Product->Scheme->Edit Scheme" 或者直接按 "command + shift + <" 快捷鍵，在彈出的窗口中"Environment Variables" 下添加 "OS_ACTIVITY_MODE",value為:"disable".如下圖:
