使用Twilio API/SDK在iOS上創建基本電話應用程序

Question

Twilio文檔表明可以創建一個簡單的iOS應用程序來發出和接收呼叫。甚至還有一個示例項目。名爲MonkeyPhone的示例項目包含ARC錯誤，因此拒絕運行。

更廣泛的問題是，Twilio是用於在iOS或Android應用上放置和接收呼叫的最佳API /平臺嗎？

Answer 1

爲此，您可以使用TCConnectionDelegate方法。它會自動處理您的呼叫過程。這個步驟你不得不遵循。

1>您需要首先創建一個twilio帳戶並獲得帳戶SID和身份驗證令牌

2>之後去到開發工具 - > TWIML應用

創建一個新的twiml應用程序並創建

請提及您要通過電話號碼的語音請求URL。

3>將您的手機號碼上TCConnectionDelegate連接方法

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

4>現在通過傳遞accountSid，的authToken，APPID您auth.php文件在服務器上得到認證令牌。

#pragma mark - 
    #pragma mark TCDevice Capability Token 

    -(NSString*)getCapabilityToken:(NSError**)error 
    {
