从gallery ionic2 angular 2加载图片

Question

我正在使用ionic2和angular2来开发移动应用。

在页面中，用户必须从图库/相机加载图像。

从相机加载图像工作正常。但是从图库加载图片不起作用。它也会导致相机。

this.camera.PictureSourceType.PHOTOLIBRARY 也会导致相机。

我的代码如下：

-s

请帮帮我。提前致谢

此外，Android中的麦克风工作正常没有任何问题。但是对于ios来说，麦克风并没有预期的工作。我有什么改变吗？

import { Camera, CameraOptions } from '@ionic-native/camera';
import { SpeechRecognition } from '@ionic-native/speech-recognition';

 takePicture(type) {
 this.showActionSheet(type);
  }

  public showActionSheet(type) {
   let actionSheet = this.actionSheetCtrl.create({
    title: 'Choose the source type',
    buttons: [{
     icon: 'camera',
     text: 'Camera',
     handler: () => {
      this.loadImage(this.camera.PictureSourceType.CAMERA, type);
     }
    }, {
     icon: 'image',
     text: 'Gallery',
     handler: () => {
      this.loadImage(this.camera.PictureSourceType.PHOTOLIBRARY, type);
     }
    }, {
     text: 'Cancel',
     role: 'cancel'
    }]
   });
   actionSheet.present();
  }

  private loadImage(selectedSourceType: number, type) {
   let cameraOptions: CameraOptions = {
    sourceType: selectedSourceType,
    destinationType: this.camera.DestinationType.FILE_URI,
    quality: 100,
    allowEdit : true,
    encodingType: this.camera.EncodingType.JPEG,
    mediaType: this.camera.MediaType.PICTURE,
    correctOrientation: true,
   }
   this.camera.getPicture({
    destinationType: this.camera.DestinationType.DATA_URL,
   }).then((imageData) => {
    if (type === 'single') {
     this.base64Image = "data:image/jpeg;base64," + imageData;
    } else {
     this.image = "data:image/jpeg;base64," + imageData;
     this.imageList.push(this.image);
    }
   }, (err) => {
    console.log(err);
   });
  }
