1.照相机

1. 下载依赖

        ionic cordova plugin add cordova-plugin-camera

        npm install @ionic-native/camera

2. app.module.ts 导入

         import { Camera } from '@ionic-native/camera/ngx';

3. 使用

openGallery(): Promise<Array<string>> {
return new Promise((resolve, reject) => {
  let arr = new Array<string>();
  const options: ImagePickerOptions = {
    quality: 100,
    maximumImagesCount: 3,
    outputType: 1
  }

  this.imagePicker.getPictures(options).then((results) => {
    for (var i = 0; i < results.length; i++) {
      arr.push('data:image/jpeg;base64,' + results[i]);
      console.log("黄 url " + results[i]);

    }
    resolve(arr);
  }, (err) => {
    resolve(new Array());
  });
})  }

注意： IOS 10 需要在 config.xml 里的 <platform name='ios'> 声明权限

<config-fileparent="NSCameraUsageDescription"platform="ios"target="*-Info.plist"><string>You can take photos</string></config-file>

3. 使用问题

使用图库插件选择图片的时候会发现界面为英文界面，需修改插件源码，目前只修改了android 源码，IOS的以后更新

项目 platforms\android\app\src\main\res  目录下

    增加values-zh 文件，新建  multiimagechooser_strings_hu.xml 文件

multiimagechooser_strings_hu.xml 文件内容

<?xml version="1.0" encoding="utf-8"?>
<resources>
  <string name="multi_app_name">圖片選擇器</string>
  <string name="free_version_label">還可以選擇 %d 張圖片</string>
  <string name="error_database">打開圖庫出錯</string>
  <string name="requesting_thumbnails">請求縮略圖，請耐心等候</string>
  <string name="multi_image_picker_processing_images_title">正在處理...</string>
  <string name="multi_image_picker_processing_images_message">請稍候...</string>
  <string name="discard" translatable="false">取消</string>
  <string name="done" translatable="false">確認</string>
</resources>  

\platforms\android\app\src\main\java\com\synconset 目录下
MultiImageChooserActivity.java 类 197行 修改
