我想使用自己的逻辑来请求签名，但签名完成后，我想将签名图像（作为png）发送到DocuSign Envelope。我查看了“为无帐户签名者设置签名图像”流程，它似乎工作正常，但签名图像没有嵌入我的信封中。
这就是我正在做的事情
一切似乎都没有任何错误。但我没看到图像。如果我做错了或者您有任何将签名图像发送到信封的示例，请告诉我。
答案 0 :(得分：0)
请随时与我们联系以获得更具创意的解决方案，但在iPad上获取签名的最简单方法是将签名图像集合委托给DocuSign。这是一种在模板上获取签名的方法（您也可以使用文档字节流）。这取自GitHub要点：https://gist.github.com/Ergin008/5645812。
签名视图可以在iOS应用中的网页浏览中显示。

// API Walkthrough 8 - Launch the signing (recipient) view of an envelope in an embedded session

// To run this sample:
// 1. Copy the below code into your iOS project
// 2. Enter your email, password, integrator key, name, templateId, and roleName and save
// 3. Run the code
//

// use same name as template role you saved through the Console UI
NSString *roleName = @"<#roleName#>";
// need to login to the console and copy a valid templateId into this string
NSString *templateId = @"<#templateId#>";
