Ionic Framework ionic-v3

After I update to xcode 9 and build the app, the native camera plugin I used, the preview img [src]= filePath was become blank, and I change it to base64 data, the data is empty. (i.e. Android is working fine). Anyonr know what happen?

        let cameraOptions = {
          sourceType: this.camera.PictureSourceType.CAMERA,
          destinationType: this.camera.DestinationType.FILE_URI,      
          quality: 100,
          targetWidth: 600,
          targetHeight: 600,
          encodingType: this.camera.EncodingType.JPEG,      
          correctOrientation: true
        }

        this.camera.getPicture(cameraOptions)
        .then(file_uri => {
              this.imageSrc = file_uri;
        },
        err => console.log(err));

html:

    <img (tap)="openGallery()"  [src]="imageSrc"/>
