title: How to flip a sprite in SpriteKit?
body: <p>I'm trying to flip a sprite in SpriteKit. it can be done in cocos2d with CCOribitCamera like this:</p>
  
  <pre><code>id firstAction = [CCOrbitCamera actionWithDuration:d/2 radius:1 deltaRadius:0 angleZ:0            deltaAngleZ:90 angleX:0 deltaAngleX:0];
  id secondAction = [CCOrbitCamera actionWithDuration:d/2 radius:1 deltaRadius:0 angleZ:270     deltaAngleZ:90 angleX:0 deltaAngleX:0];
  
  [self runAction: [CCSequence actions:firstAction,
  [ImageSwapAction actionWithCard: self],
  secondAction, nil]];
  </code></pre>
  
  <p>Any ideas?</p>

  Thanks for nickfalk's answer, I figured it out.</p>
  
  <pre><code>[sprite runAction:[SKAction sequence:@[
                                            [SKAction scaleXTo:0 duration:0.2],
                                            [SKAction runBlock:^{
              [sprite swapImage];
          }],
                                            [SKAction scaleXTo:1 duration:0.2]
                                            ]]];
  </code></pre>
