UIImagePickerController asks for access to photos

Even though I am not saving the photos anywhere but whenever I access the edited image in the didFinishPickingMediaWithInfo function, iOS asks me for permission to access photos on the device.

Any idea how to prevent it from asking permission.

Adding UIImagePickerController

- (IBAction)addPhotoButtonPressed:(id)sender {

    UIImagePickerController *picker = [[UIImagePickerController alloc] init];
    picker.delegate = self;
    picker.allowsEditing = YES;
    picker.sourceType = UIImagePickerControllerSourceTypeCamera;

    picker.showsCameraControls = YES;

    [self presentViewController:picker animated:YES completion:NULL];


}

didFinishPickingMediaWithInfo

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


    [picker dismissViewControllerAnimated:YES completion:nil];

    UIImage *image;

   image = [info objectForKey:@"UIImagePickerControllerEditedImage"];


    if (image == nil)
        image = [info objectForKey:@"UIImagePickerControllerOriginalImage"];


    NSData *imageData = UIImageJPEGRepresentation(image, 0.05f);
    _locationImage.image = [UIImage imageWithData:imageData];
    imageFile = [PFFile fileWithName:@"Image.jpg" data:imageData];

    }

I don't see any way shy of writing your own editing control (which isn't that hard though) Then you have full control.

the UIImagePicker is asking that - I guess - because it saves the original image temporarily as if it were saved indeed...

you must know that when accessing the photo gallery for the first time the permission must be requested from the user.

http://www.macrumors.com/2012/06/14/apple-requires-user-permission-before-apps-can-access-personal-data-in-ios-6/

Alo you must check the permission by 

AVAuthorizationStatus authStatus = [AVCaptureDevice authorizationStatusForMediaType:mediaType];
if(authStatus == AVAuthorizationStatusAuthorized) {
  // do your logic
} else if(authStatus == AVAuthorizationStatusDenied){
  // denied
} else if(authStatus == AVAuthorizationStatusRestricted){
  // restricted, normally won't happen
} else if(authStatus == AVAuthorizationStatusNotDetermined){
  // not determined?!
  [AVCaptureDevice requestAccessForMediaType:mediaType completionHandler:^(BOOL granted) {
    if(granted){
      NSLog(@"Granted access to %@", mediaType);
    } else {
      NSLog(@"Not granted access to %@", mediaType);
    }
  }];
} else {
  // impossible, unknown authorization status
}
