ios - 在 IOS 上，寻找在 google place sdk 中检测当前位置的选项

Question

我不熟悉 Swift3，但是我正在让自由职业者开发我的应用程序，但他们说，他们无法在我用 swift3 开发的 IOS 应用程序中添加检测当前位置的 google place api sdk 实现来搜索地址。我正在尝试实现如下所示的地址搜索页面

此功能中的任何指针都会有很大帮助。请分享我可以与开发人员分享以实现的此类实现的任何示例/教程。

首次安装

pod 'GooglePlaces'
pod 'GooglePlacePicker'
pod 'GoogleMaps'

然后按照下面的代码只是为了查看

import GoogleMaps
import GooglePlaces
