我是 PhoneGap 的新手，想知道如何将应用内图像保存到 iOS 中的照片.
I am new to PhoneGap and would like to know how to save an in-App image to Photos in iOS.

I recently came across the following Phonegap plugin for saving Canvas images to Photos in iOS: https://github.com/devgeeks/Canvas2ImagePlugin

<script type="text/javascript" charset="utf-8" src="../Canvas2Image/Canvas2ImagePlugin.js"></script>
<script type="text/javascript" charset="utf-8">
var canvas2ImagePlugin; //devgeeks plugin for saving canvas images to photo gallery
function onDeviceReady() {
canvas2ImagePlugin = window.plugins.canvas2ImagePlugin;
}
function savePicture(){
canvas2ImagePlugin.saveImageDataToLibrary(function(msg){console.log(msg);},function(err){console.log(err);},'mycanvas');
}
</script>
</head>
<body>
<canvas id="myCanvas" width="500px" height="300px"> <strong>[Your browser can not show this example.]</strong> </canvas>
