使用 Phonegap/Cordova 相机插件从相机或图库中选择照片答案

【问题标题】：Using the Phonegap/Cordova camera plugin select photo from camera OR gallery使用 Phonegap/Cordova 相机插件从相机或图库中选择照片
【发布时间】：2013-11-23 15:40:38
【问题描述】：

我正在使用 Phonegap 3.0.0 相机插件 (https://build.phonegap.com/plugins/242)。我想让用户上传照片。 sourcetype 的当前选项是：

Camera.PictureSourceType.CAMERA

Camera.PictureSourceType.SAVEDPHOTOALBUM

Camera.PictureSourceType.PHOTOLIBRARY

是否有任何 sourcetype 可以同时向用户显示所有这三个选项？我希望用户能够选择画廊或相机。我认为这是您点击< input type="file"/> 时移动浏览器中的典型行为。
