Google Maps iOS API密钥无效

我有一个简单的iOS应用程序，我正在整合Google地图。但是，当我的地图视图显示时，我提供的API密钥会导致其中一些错误消息：

I have a simple iOS app into which I am integrating Google Maps. However, the API key I've provided results in several of these error messages when my map view is displayed:

ClientParametersRequest失败，剩余3次尝试（0 vs 5）。错误域= com.google.HTTPStatus代码= 400无法完成操作。（com.google.HTTPStatus错误400.）UserInfo = 0x1818bf40 {data =< CFData 0x18137410 [0x302aec8]> {length = 145 ，容量= 256，字节= ...}}

这是我已经尝试过无效的事情：

Here is what I have already tried to no avail:

• 调用 [GMSServices provideAPIKey：] 作为中的第一行代码didFinishLaunchingWithOptions


• 仔细检查我的API密钥是否正确并且是iOS API密钥（我将其直接从Google Cloud Console复制/粘贴到我的应用中）


• 使用 {} 提供API密钥而不使用


• 通过输出确认我的包名称它与 [[Bundle mainBundle] bundleIdentifier]


• 完全省略捆绑标识符限制


• 重新生成API密钥

• Calling [GMSServices provideAPIKey:] as the first line of code within didFinishLaunchingWithOptions
• Double-checking that my API key is correct and is an iOS API key (I copy/pasted it directly from the Google Cloud Console into my app)
• Providing the API key both with {} and without
• Confirming my bundle name by outputting it with [[Bundle mainBundle] bundleIdentifier]
• Omitting bundle identifier restrictions altogether
• Regenerating the API key

我不知道还有什么可以尝试。我的捆绑包名称采用以下格式： net.company.MyApp 我已将其完全输入到Google云端控制台（我知道捆绑包ID区分大小写）。

I am not sure what else to try. My bundle name is in this format: net.company.MyApp and I have entered it exactly that way into the Google Cloud Console (I know bundle IDs are case-sensitive).

可能是Google不支持某种类型的包标识符（例如，使用大写字母或以 net开头。）？

Could it be that Google doesn't support bundle identifiers of a certain type (e.g., with upper-case letters or beginning with net.)?
