Photos that are not geometric - How can I focus photos in my iPhone app?

When you take photos with your iPhone camera, they automatically snap to geometry.

I wrote down the following code to take photos in GPS Recorder app, but the photos are not geometrically bound.

What am I doing wrong? Should I use a completely different method or can I somehow modify my code to add geotag and other data to the EXIF ​​information?

Note that self.photoInfo is the dictionary of information returned by this delegate method:

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {

      

        
        
        
      

    

Here's the code:

UIImage *oImage = [self.photoInfo objectForKey:UIImagePickerControllerOriginalImage];

CGSize size = oImage.size;

oImage = [CameraController imageWithImage:oImage 
  scaledToSize:CGSizeMake(size.width/2.56,size.height/2.56)];

NSDictionary *info = [[NSDictionary alloc] initWithObjectsAndKeys:
  oImage, @"image", titleString, @"title", nil];

TrailTrackerAppDelegate *t = (TrailTrackerAppDelegate *)[[UIApplication sharedApplication] delegate];
[NSThread detachNewThreadSelector:@selector(saveImage:) toTarget:t withObject:info];


+ (UIImage*)imageWithImage:(UIImage*)image scaledToSize:(CGSize)newSize {

  UIGraphicsBeginImageContext( newSize );
  [image drawInRect:CGRectMake(0,0,newSize.width,newSize.height)];
  UIImage* newImage = UIGraphicsGetImageFromCurrentImageContext();
  UIGraphicsEndImageContext();

  return newImage;
}

      

        
        
        
      

    

Here is a photo taken with a camera that has all the good EXIF ​​data: http://www.flickr.com/photos/ 33766454 @ N02 / 3978868900 /

And here we took with my code, which has no EXIF ​​data: http://www.flickr.com/photos/ 33766454 @ N02 / 3978860380 /
