Xcode8 以上控制台打印一堆,以及多行注释不灵...

1.多行注释问题:

• 发现升级Xcode8以后 "command + /" 不好使了,身为一个程序员这样的问题不解决?不能够啊...解决办法 如下:

   sudo /usr/libexec/xpccachectl

• PS:然后必须重启电脑后生效

2.控制台打印一堆问题:

• 升级Xcode8以后控制台会打印许多网络相关的日志:

[html] view plain copy  print?

[] -[NWConcrete_tcp_connection dealloc] 5

• 解决办法:选择"Product->Scheme->Edit Scheme" 或者直接按 "command + shift + <" 快捷键，在弹出的窗口中"Environment Variables" 下添加 "OS_ACTIVITY_MODE",value为:"disable".如下图:
