首先html 文件

import {ImagePicker} from 'ionic-native';

 设置export class ContactPage {} 里面的默认的headface头像

public user={       username : '',       userpassword :'' ,       headface:'images/2.png'  }

uploadImages(){   let options = {                maximumImagesCount: 10,            };    ImagePicker.getPictures(options).then((results) => {  for (var i = 0; i < results.length; i++) {      alert('Image URL: ' + results[i]);  }}, (err) => {     alert('Image ERR: ' + err);  });}

注意先要安装imagePicker插件，命令：ionic plugin add cordova-plugin-image-picker

浏览器中看不出效果，要打包

ionic build android 或者cordova build android

后在真机或者模拟器上看
