Question

您好我无法复制iPhone手机上的官方本地目录。我在这个函数copyFileToLocalDir收到错误。每当我从手机的图库和相机中获取图片时，我总会收到错误消息。在Android手机上的每张照片后，每张照片都在本地线上。我怎么才能得到它？在 Android 手机上无缝工作时，为什么它适用于 iOS 手机？

presentActionSheet(){
    let actionSheet = this.actionSheetCtrl.create({
      title : "Resim Kaynağını Seçiniz",
      buttons : [{
        text : "Galeriden Seç",
        handler : ()=>{ 
this.takePicture(this.camera.PictureSourceType.PHOTOLIBRARY);
        }
      },{
        text : "Resim Çek",
        handler : ()=>{
          this.takePicture(this.camera.PictureSourceType.CAMERA);
        }
      }]
    });
    actionSheet.present();
  }
  takePicture(SOURCETYPE){
    var options = {
      quality : 25,
      sourceType : SOURCETYPE,
      destinationType : this.camera.DestinationType.FILE_URI,
      encodingType : this.camera.EncodingType.JPEG,
      saveToPhotoAlbum : false,
      correctOrientation : true
    };
    var yerelDizinAndroid;
    var yerelDizinIOS;
    this.camera.getPicture(options).then((imagePath)=>{
      if(this.platform.is('android') && SOURCETYPE === this.camera.PictureSourceType.PHOTOLIBRARY){
        this.filePath.resolveNativePath(imagePath).then(filePath =>{
          let correctPath = filePath.substr(0, filePath.lastIndexOf('/') + 1);
          let currentName = imagePath.substring(imagePath.lastIndexOf('/') + 1, imagePath.lastIndexOf('?'));
          yerelDizinAndroid = currentName;
          this.copyFileToLocalDir(correctPath, currentName, this.createFileName());
        });
      }else {
      var currentName = imagePath.substr(imagePath.lastIndexOf('/') + 1);
      var correctPath = imagePath.substr(0, imagePath.lastIndexOf('/') + 1);
      yerelDizinIOS = currentName;
      this.copyFileToLocalDir(correctPath, currentName, this.createFileName());
    }
    }, (err) => {
    this.presentToast('Herhangi bir işlem yapılmadı.');
  /*  this.file.removeDir(cordova.file.dataDirectory, yerelDizinAndroid);
    this.file.removeDir(cordova.file.dataDirectory, yerelDizinIOS); */
  });
}
  private createFileName() {
    var newFileName =  "S" + window.localStorage.getItem("auth_key") + ".jpg";
    return newFileName;
  }
  private copyFileToLocalDir(namePath, currentName, newFileName) {
    this.file.copyFile(namePath, currentName, cordova.file.dataDirectory, newFileName).then(success => {
      this.lastImage = newFileName;
    }, (error) => {
      this.presentToast('Görsel yerel dizine taşınamadı..');
    });
  }
