-(void)actionLayer
{ 
isRunning = 0;

addPixedlValue += 19;
id  actionMove = [CCMoveTo actionWithDuration:6 position:ccp( 50,109)];  //300,100


id actionMoveDone = [CCCallFuncN actionWithTarget:self selector:@selector(LayerAction:)];

animateAction  = [CCSequence actions:actionMove, actionMoveDone, nil];


NSLog(@"pixel value %d",addPixedlValue);



[boxSprite runAction:animateAction];    

}


 -(void)LayerAction:(id)sender
{
addPixedlValue +=19;
id  actionMove = [CCMoveTo actionWithDuration:6 position:ccp( 270,109)];  //300,100


id actionMoveDone = [CCCallFuncN actionWithTarget:self  selector:@selector(actionLayer)];

animateAction  = [CCSequence actions:actionMove, actionMoveDone, nil];

[boxSprite runAction:animateAction];
}

I think your problem can be sort out By scheduling a selector for a time interval say 0.1 and you can update the position according to your self.

-(void)moveSprite
{
   sprite.position = ccp ( sprite.position.x + 5 , sprite.position.y); 
}

And unshedule the selector whenever needed to stop the sprite.

For Scheduling a selector

[self schedule : @selector ( moveSprite ) interval : 0.1];

For unscheduling

[self unschedule : @selector ( moveSprite )]; 

This help you in make jerking movement.
