关于更新到Xcode8后答应了很多网络日志的，会影响到我们需要的日志的混淆，下面是解决办法
product —> scheme —> Edit Scheme —> Run —> Argument —> Environment Variable
添加 key：OS_ACTIVITY_MODE
value ：disable 就可以停止输出打印此日志
第一步，打开product
第二步 run - Arguments
第三步
添加参数：
Name ：OS_ACTIVITY_MODE
Value : disable
解决Xcode8打印了nw_socket_handle_socket_event Event mask
