求大神帮忙实现 voip + socket 后台休眠长连接问题，附项目源码

raozhiven 2014-09-21 12:16:32

各位大神，首次开发iOS项目，需要用到Socket通讯，现服务端已写好，客户端用以下这个工程源码可以正常连接服务端并返回数据。但客户端程序在切换到后台后，Socket通讯被停止，不一会儿就断开了。

baidu查资料，说需要用到 voip 实现后台长连接：

iOS应用中通过设置VOIP模式实现休眠状态下socket的长连接
voip与socket实现后台推送

但小弟对Xcode环境及语法不熟，无法根据文档完成，哪位大神帮忙实现或指导下？

你这个是怎么得到的？

文章中提到了，需要打开Background Modes. 不知道你尝试之后的结果如何。打开后台模式应该可以让你的应用常驻

我在_initializeStreams方法里添加了这两句后，未加之前切换到后台几秒钟就断开了。切换到后台能正常执行一段时间，然后出现异常 lldb ，用 bt 得出异常信息如下：
