title: Memory Warning UIImagepickerController IOS 7
body: <p>Could anybody help me with this issue  I'm a bit new to objective c and iOS. I've been working on it but I can't figure out how to fix the problem, My app is really simple it only start the camera take pictures and send them through email to our server. This code was working just fine in iOS6.</p>
  
  <p>When I take pictures my memory is heap growth with each screen capture and I get "Received Memory Warning" and finally - Terminated due to Memory Pressure. -</p>
  
  <pre><code>-(void)imagePickerController:(UIImagePickerController *)picker
  didFinishPickingMediaWithInfo:(NSDictionary *)info
  {
  
  [self.popoverController2 dismissPopoverAnimated:true];
  NSString *mediaType = [info
                         objectForKey:UIImagePickerControllerMediaType];
  
  if ([mediaType isEqualToString:(NSString *)kUTTypeImage]) {
      _image = [info
                        objectForKey:UIImagePickerControllerOriginalImage];
  
     _image = [self fixrotation:_image]; //&lt;----- increased memory when UIImageWriteToSavedPhotosAlbum is uncommented IF is comment it doesn't increased memory but after some pictures I start to get "Received Memory Warning" message until the app Crash.
  
      if (_newMedia){
         UIImageWriteToSavedPhotosAlbum(_image,
                                         self,@selector(image:finishedSavingWithError:contextInfo:),
                                         nil);

  <p>probably is a memory management. I will appreciate your help</p>
