How to take low res photos from camera and display in imageview

hi in my application i am able to take a photo from the camera and display it in an image view

my question is how would i make it take a low res photo as the image i take is high res and slows down my app due to it being so much memory

so overall i would like the app to take very low resolution images

here is my code

- (IBAction)TakePhoto:(id)sender {
    picker = [[UIImagePickerController alloc] init];
    picker.delegate = self;
    [picker setSourceType:UIImagePickerControllerSourceTypeCamera];
    [self presentViewController:picker animated:YES completion:NULL];
    }

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
        image = [info objectForKey:UIImagePickerControllerOriginalImage];
        [ImageView setImage:image];    // "myImageView" name of any UImageView.
        [self dismissViewControllerAnimated:YES completion:NULL];
}

-(void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
    [self dismissViewControllerAnimated:YES completion:NULL];
}

In internet you can find scaledToSize function:
+ (UIImage*)imageWithImage:(UIImage*)image scaledToSize:(CGSize)newSize;
{
    // Create a graphics image context
    UIGraphicsBeginImageContext(newSize);

    // Tell the old image to draw in this new context, with the desired
    // new size
    [image drawInRect:CGRectMake(0,0,newSize.width,newSize.height)];

    // Get the new image from the context
    UIImage* newImage = UIGraphicsGetImageFromCurrentImageContext();

    // End the context
    UIGraphicsEndImageContext();

    // Return the new image.
    return newImage;
}

Open in new window

It will resize the image, reduce resolution, etc.
