CALayer Animation - objective-c

Question

I'm a beginner and I trying continue to familiarize myself with CALayer ...
Thanks again #Alexsander Akers, #DHamrick and #Tommy because now I can skew my CALayer !
It look like :
I would like to move my finger on the Gray UIView (with touchesBegan/touchesMoved/touchesEnded) and my "cards" move like this :
(For exemple if I move my finger left)
the yellow card disappear & the green one take is place
white take the green's place
red the white
blue the red one
and instead of a blue card a Black one appear ...
Maybe I'm dreaming and it's to hard for me, but if if you can give me advice I'll take it !!
thank you !

You may use the customized function like this
- (void)moveAndRotateLayer: (CALayer *)layer withDuration:(double)duration degreeX:(double)degreeX y:(int)degreeY angle:(float)angle autoreverseEnable:(BOOL)ar repeatTime:(int)repeat andTimingFunctionType:(NSString *)type
{
// You should type the timing function type as "Liner", "EaseIn", "EaseOut" or "EaseInOut".
// The default option is the liner timing function.
// About these functions, look in the Apple's reference documents.
CAAnimationGroup *theGroup = [CAAnimationGroup animation];
CGPoint movement = CGPointMake(layer.position.x + degreeX, layer.position.y + degreeY);
NSArray *animations = [NSArray arrayWithObjects:[self moveLayers:layer to:movement duration:duration], [self rotateLayers:layer to:angle duration:duration], nil];
theGroup.duration = duration;
theGroup.repeatCount = repeat;
theGroup.autoreverses = ar;
if ([type isEqualToString:#"EaseIn"])
{
theGroup.timingFunction = [CAMediaTimingFunction functionWithName: kCAMediaTimingFunctionEaseIn];
}
else if ([type isEqualToString:#"EaseOut"])
{
theGroup.timingFunction = [CAMediaTimingFunction functionWithName: kCAMediaTimingFunctionEaseOut];
}
else if ([type isEqualToString:#"EaseInOut"])
{
theGroup.timingFunction = [CAMediaTimingFunction functionWithName: kCAMediaTimingFunctionEaseInEaseOut];
}
else
{
theGroup.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionLinear];
}
theGroup.animations = [NSArray arrayWithArray:animations];
[layer addAnimation:theGroup forKey:#"movingAndRotating"];
}
This is the solution of the animation just for moving and rotating the layer,
but, I know that you can customizing yourself.
It's very good for you. You can make it.
Good luck!
