-------------------------------------

Hello,
I need to get the Exif info on the jpeg at the server side and i fall in th=
is bug.
I first tried to find a fix but searching in apple documentation i found so=
mething simpliest.
I very new to IOS and cordova but i would like to share the way i do it:

instead of
   CDVJpegHeaderWriter* exifWriter =3D [[CDVJpegHeaderWriter alloc] init];
   NSString* headerstring =3D [exifWriter createExifAPP1:[info objectForKey=
:@"UIImagePickerControllerMediaMetadata"]];
   [exifWriter spliceExifBlockIntoJpeg:data withExifBlock:headerstring];

i do
  NSDictionary *metadata =3D [info objectForKey:@"UIImagePickerControllerMe=
diaMetadata"];
  if (metadata) {
   CGImageSourceRef sourceImage =3D CGImageSourceCreateWithData((__bridge_r=
etained CFDataRef)data, NULL);
   CFStringRef sourceType =3D CGImageSourceGetType(sourceImage);
                   =20
   CGImageDestinationRef destinationImage =3D CGImageDestinationCreateWithD=
ata((__bridge CFMutableDataRef)data, sourceType, 1, NULL);
   CGImageDestinationAddImageFromSource(destinationImage, sourceImage, 0, (=
__bridge CFDictionaryRef)metadata);
   CGImageDestinationFinalize(destinationImage);
                   =20
   CFRelease(sourceImage);
   CFRelease(destinationImage);
 }

> multi-part (complex) tags are not written correctly. this leads to an exi=
f string which is of the correct size (and therefore is not reported as an =
error) but cannot be read back out.
