• 《转载》IOS高级开发~开机启动&无限后台运行&监听进程


    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
