Problem

Cordova plugin camera get picture. metadata not found in cordova ios

What is expected to happen?

Get metadata data when taking photos on iOS

What does actually happen?

When I upload a photo using Android, the photo has metadata information, but when I upload a photo using iOS, there is no metadata information. I used the exifjs library (https://cdn.jsdelivr.net/npm/exif-js) to test and the results are as follows: android:

ios:

Information

I see @erisu has committed on this issue! I see that cordova plugin camere version 7.0.0 mentions preserving metadata on ios.

Command or Code

`

base64ToArrayBuffer: function(base64) {
          base64 = base64.replace(/^data\:([^\;]+)\;base64,/gmi, "");
          var binary = atob(base64);
          var len = binary.length;
          var buffer = new ArrayBuffer(len);
          var view = new Uint8Array(buffer);
          for (var i = 0; i < len; i++) {
              view[i] = binary.charCodeAt(i);
          }
          return buffer;
      },
  snapPicture: function(callBack) {
          navigator.camera.getPicture(successCamera, failCamera, { 
              destinationType: Camera.DestinationType.DATA_URL,
              correctOrientation: true
          });

    function successCamera(base64) {
        let arrayBuffer = base64ToArrayBuffer(base64Image);
        let dataExif = EXIF.readFromBinaryFile(arrayBuffer);
        if (dataExif && dataExif.DateTime) {
          alert("Exif Date: " + dataExif.DateTime);
        } else {

        }
    }

I've made a patch where EXIF Metadata is available again. Let me know if you still need it and I can share. It will be nice to have someone else testing :)

I have run into the same problem where iOS is not capturing the exif data. If you could share your patch, that would be great. Thank you.
