IOS高级开发～开机启动&无限后台运行&监听进程

原文:http://tec.5lulu.com/detail/108k5n1e6l6zy8s1e.html

非越狱情况下实现：

       开机启动：App安装到IOS设备设备之后，无论App是否开启过，只要IOS设备重启，App就会随之启动；

       无限后台运行：应用进入后台状态，可以无限后台运行，不被系统kill；

       监听进程：可获IOS设备运行除系统外的App（包括正在运行和后台运行）；

       配置项目 plist文件

       添加：

<key>UIBackgroundModes</key>
<array>
<string>voip</string>
</array>

       功能类：ProccessHelper
