爲無帳戶簽名人設置簽名圖像DocuSign

Question

我想使用自己的邏輯來請求籤名，但簽名完成後，我想將簽名圖像（如png）發送到DocuSign Envelope。我查看了「爲無帳戶簽名人設置簽名圖像」流程，它似乎工作正常，但簽名圖像未嵌入我的信封中。

這是我在做什麼

1. 獲取賬戶信息
2. 從模板爲「創建（草案）」狀態
3. 創建信封添加收件人
4. 添加簽名選項卡
5. 將信封狀態從「創建」更改爲「發送」
6. 設置收件人的簽名圖像。

一切似乎工作正常，沒有任何錯誤。但我沒看到圖像。如果我做錯了任何事情，或者您有任何將簽名圖像發送到信封的例子，請告訴我。

請隨時與我們聯繫以獲得更具創意的解決方案，但是在iPad上獲取簽名的最簡單方法是將簽名圖像集合委託給DocuSign。這裏是一種獲取模板簽名的方法（您也可以使用文檔字節流來完成）。這取自GitHub的要點：https://gist.github.com/Ergin008/5645812。

用於簽名的視圖可以顯示在iOS應用程序的webview中。
