推荐答案

这实际上是不可能的.您只有一次机会来提示他们授予权限.这就是为什么大多数应用程序会显示自定义视图来解释为什么需要某种权限.如果用户单击是"，则他们会启动实际的权限警报.如果他们已经拒绝了权限，您需要检查应用是否具有特定权限，并提示他们进入设置以激活所需内容.

This is actually not possible. You only get one shot to prompt them for permissions. This is why most apps will present a custom view to explain why a certain permission is needed. And if the user clicks "yes", then they launch the actual permission alert. If they have already declined the permission, you'll need to check if app has certain permission and prompt them to go into settings to activate what is needed.

这是一个示例，说明如何检查他们是否已授予权限.

Here's an example of how you can check if they have given permission.
