[] __nw_connection

给新的测试手机安装APP,wifi连接成功后,socket一直没有通讯连接,切换测试机器正常,于是乎在xcode上调试,打印如下:

[] __nw_connection_get_connected_socket_block_invoke 1 Connection has no connected handler

[] __nw_connection_get_connected_socket_block_invoke 2 Connection has no connected handler

[] __nw_connection_get_connected_socket_block_invoke 3 Connection has no connected handler

后面发现,手机第一次开机后关闭了所有的网络启动,需要进入"设置",对应APP下,选择"无线数据",切换有WIFI状态即可!
