我尝试从 android/Ios 设备捕获图像和视频并通过电子邮件发送它们。我想制作一个混合应用程序。所以我为此使用 phonegap 最新版本。我在互联网上搜索并找到了一些代码并将它们排列在一起。现在我希望该用户只能捕获 2 个视频，并且我的代码可以正常工作。但是现在当我尝试捕获图像时，它不起作用。图像不在本地存储。我还希望该用户只能捕获 5 张图像，当单击“发送”按钮时，捕获的图像和视频附加并通过电子邮件发送。 这是我的代码，我做了什么

并且此代码是否适用于 Ios 设备，或者我必须更改其中的任何内容？
我使用来自Github的 EmailComposerWithAttachments 插件
