title: How to add large background image on the UIView in a full size?
body: <p>I have a high resolution image and I want to use it as a background for a view. But when I add it either via an Interface Builder or programatically I see only its part.This doesn't help:</p>
  
  <pre><code>UIImage* _backGround = [UIImage imageNamed:@"background-clean@2x.png"];
    CGRect _viewFrame = self.view.frame;
   [_backGround drawInRect:_viewFrame];
  UIImageView* _backGroundView = [[UIImageView alloc] initWithImage:_backGround];
  [self.view addSubview:_backGroundView];
  [self.view sendSubviewToBack:_backGroundView];
  </code></pre>
  
  <p>And this too:</p>
  
  <pre><code>_backGroundView.contentMode =UIViewContentModeScaleAspectFit;
  </code></pre>
  
  <p><p> So the question how can I scale this image in order it fits in the view in a full size in spite of its size?
  P.S. Sorry for my bad English.</p>
