使用Twilio API/SDK在iOS上创建基本电话应用程序

问题描述：

Twilio文档表明可以创建一个简单的iOS应用程序来发出和接收呼叫。甚至还有一个示例项目。名为MonkeyPhone的示例项目包含ARC错误，因此拒绝运行。使用Twilio API/SDK在iOS上创建基本电话应用程序

更广泛的问题是，Twilio是用于在iOS或Android应用上放置和接收呼叫的最佳API /平台吗？

我也使用twilio Api到我的ios应用程序project.it工作正常.. – Ravindhiran 2013-02-14 04:09:31

您是否能够获得Twilio提供的HelloMonkey示例工作？ – samonderous 2013-02-15 00:56:45

答

为此，您可以使用TCConnectionDelegate方法。它会自动处理您的呼叫过程。这个步骤你不得不遵循。

1>您需要首先创建一个twilio帐户并获得帐户SID和身份验证令牌 enter image description here

2>之后去到开发工具 - > TWIML应用

创建一个新的twiml应用程序并创建 enter image description here

请提及您要通过电话号码的语音请求URL。

3>将您的手机号码上TCConnectionDelegate连接方法

YourTwilioDeviceClass *phone = appDelegate.phone; 
    [phone connect:self.textFieldPhoneNumber.text];

4>现在通过传递accountSid，的authToken，APPID您auth.php文件在服务器上得到认证令牌。
