Twilio 文档表明可以创建一个简单的 iOS 应用来调用和接听电话。甚至还有一个示例项目。名为 MonkeyPhone 的示例项目包含 ARC 错误，因此它拒绝运行。
更广泛的问题是，Twilio 是用于在 ios 或 android 应用程序上调用和接听电话的最佳 API/平台吗？
最佳答案
为此，您可以使用 TCConnectionDelegate 方法。它会自动处理您的调用程序。
这是您必须遵循的几个步骤。
1.> 需要先创建一个twilio账号，获取账号sid和auth token
2.> 之后转到 Dev tools -> TWIML Apps
新建一个twiml app并创建
请提及您将在其中传递电话号码的语音请求 URL。
3.> 将您的电话号码传递给 TCConnectionDelegate 连接方法
YourTwilioDeviceClass *phone = appDelegate.phone;
[phone connect:self.textFieldPhoneNumber.text];
4.> 现在通过将 accountSid、authToken、appId 传递到服务器上的 auth.php 文件来获取身份验证 token 。

#pragma mark TCDevice Capability Token
