Horizontally mirror a SKSpriteNode texture

I'm developing an iOS7 game with the new API called Sprite Kit. I'd like to horizontally rotated a SKSpriteNode image/texture. I've tried it by first mirroring the image, then creating a SKTexture and finally applying it to the SKSpriteNode but it doesn't work. Is there some way to do this? Or I should have to different images?

You can use this code to flip among x-axis:

spriteNode.xScale = spriteNode.xScale * -1;

but be careful you can lose some of physicsbody's property, I highly suggest u to use xScale in this way:

spriteNodeBody = [SKNode node];
spriteNodeBody.physicsBody = [SKPhysicsBody bodyWithRectangleOfSize:spriteNode.size];
spriteNodeBody.physicsBody.categoryBitMask = CNPhysicsCategoryPlayer;
spriteNodeBody.physicsBody.collisionBitMask = CNPhysicsCategoryBall;

[spriteNodeBody addChild:spriteNode];
[self addChild:spriteNodeBody];

And now you can safely use:

    spriteNode.xScale = spriteNode.xScale * -1;
