get-task-allow和keychain-access-groups

今天上传版本，无意中看到app信息中有几个没见过的条目。。截图如下:

对于get-task-allow的解释如下：

get-task-allow, when signed into an application, allows other processes (like the debugger) to attach to your app. Distribution profiles require that this value be turned off, while development profiles require this value to be turned on (otherwise Xcode would never be able to launch and attach to your app).

关于keychain-access-groups：

用于两个app共享数据。这个具体的应用我会写篇blog来说明。其他的就不解释了。。一眼看穿。
