里面的PhotoSelectOptions对象的isEditSupported11+，就可以用系统自带的裁剪页面。

import photoAccessHelper from '@ohos.file.photoAccessHelper';
import { BusinessError } from '@kit.BasicServicesKit';

const photoSelectOptions = new photoAccessHelper.PhotoSelectOptions();

choosePhoto() {
  photoSelectOptions.MIMEType = photoAccessHelper.PhotoViewMIMETypes.IMAGE_TYPE; // 过滤选择媒体文件类型为VIDEO
  photoSelectOptions.maxSelectNumber = 1;
  // 选择媒体文件的最大数目
  photoSelectOptions.isPhotoTakingSupported = true
  photoSelectOptions.isEditSupported = true
  let uris: Array<string> = [];
  const photoViewPicker = new photoAccessHelper.PhotoViewPicker();
  photoViewPicker.select(photoSelectOptions).then(async (photoSelectResult: photoAccessHelper.PhotoSelectResult) => {
    uris = photoSelectResult.photoUris;
  }).catch((err: BusinessError) => {
    console.error(`Invoke photoViewPicker.select failed, code is ${err.code}, message is ${err.message}`);
  })
}
