这就是它为我工作的方式：

我添加了OpenTok SDK，并将其导入到进度栏控制器中
我创建了一个函数func connectToAnOpenTokSession()
并在点击按钮时将其与进度条功能public func setProgressNetwork(to progressConstant: Double, withAnimation: Bool)一起调用。

对于预呼叫，您必须选择其他会话ID。

//ProgressViewController
func connectToAnOpenTokSession() {
session = OTSession(apiKey: kApiKey, sessionId: kSessionId, delegate: self as OTSessionDelegate)
var error: OTError?
session?.connect(withToken: kToken, error: &error)
if error != nil {
    print(error!)}
}

//TestViewController
@objc func handleTapNetwork() {
progressBar.connectToAnOpenTokSession()
progressBar.safePercent = 100
progressBar.setProgressNetwork(to: 1, withAnimation: true)}

//TestViewController
@IBAction func networkButtonAction(_ sender: UIButton) {        
    networkButton.addTarget(self, action: #selector(handleTapNetwork), for: 
   .primaryActionTriggered) }

在使用OpenTok iOS SDK在iOS App中实施呼叫前测试方面需要帮助
