【问题描述】：

在 IOS 上请求位置权限时始终打开，一段时间后系统会向用户提示一个对话框，说 the app whats to use the location in the background 或类似的东西。

如何更改此对话框的描述？是其中之一吗？

    <key>NSLocationWhenInUseUsageDescription</key>
    <key>NSLocationAlwaysUsageDescription</key>
    <key>NSLocationAlwaysAndWhenInUseUsageDescription</key>

【问题讨论】：

见Choosing the Authorization Level for Location Services 和 Requesting Always Authorization 和 Requesting When-In-Use Authorization
@Honey 这不是很有帮助。如果用户在对话框位置权限中单击始终允许，则对话框会在一段时间后弹出。在第一个对话框中，我写信给用户please chose "always allow"，当有背景的东西弹出时，我想写please chose "continue"
