由于 API 密钥无效（格式错误或丢失），操作失败

用户在搜索框中输入第一个字符时，会发生错误：

Answer 1

您遇到的此错误很可能是由您的云项目配置引起的，而不是由于您自己的代码实现引起的，特别是考虑到您在使用 Google 的示例代码时遇到相同的错误（如果您使用来自一个有效的项目）。

首先，无论您当前是否处于开发阶段，都必须在您的项目上启用计费功能，Maps API 才能正常工作。

其次，旧的适用于 IOS 的 Places SDK 已被弃用。要使用适用于 IOS 的新 Places SDK，您需要启用并添加到 API 密钥的 API 限制的 API 是Places API。

我建议您仔细阅读 Google 的入门指南，正确设置您的项目和 API 密钥，以便与适用于 IOS 的新 Places SDK 一起使用： https:

https://developers .google.com/places/ios-sdk/start

希望这可以帮助。
