Let SpriteNode follow the touch

Hello,

I'd like to let a SpriteNode follow a touchEvent. Means like when I press at the right side of the node, it should move right. when i press left, it should move to the left. And when i press over an invisible Line ( i can create them ) it should "jump". I want it to follow the touch, not that it "beams" to the touch event.

-(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {

for (UITouch *touch in touches) {
    CGPoint location = [touch locationInNode:self];                       
    CGPoint newPosition = CGPointMake(location.x, location.y);      
    SKAction *moveSanchezLeftRight = [SKAction moveToX:newPosition.x duration:1.0];
    SKAction *moveSanchezUpwards = [SKAction moveByX:0 y:100 duration:1.0];

    if(!(newPosition.x == self.sanchez.position.x))                    
    {
        [self.sanchez runAction:moveSanchezLeftRight];
    }

    if(!newPosition.y > self.sanchez.position.y){

        [self.sanchez runAction:moveSanchezUpwards];

    }
}

}

Kinda like that, but the problem is that the figure's speed is changing with the distance to the touch because i had to pick a duration. Thats not good like that. I need a constant velocity of my node.

All I want is a nice jumping move and a moving in both x directions with constant speed. That can't be impossible but I'm new to Xcode and don't really get how to do it.

Can you help me?

Kind Regards,

Robink
