How to make sprite jump higher/smaller depending on the amount of time touching screen?

Question

Hi I'm having difficulties finding the correct code to apply to my sprite to allow small jump when only taped and a higher jump when finger is on screen longer. (Please find current code below)

 override func touchesBegan(touches: Set<NSObject>, withEvent event:UIEvent) {



    /* Called when a touch begins */

    if (gameOver == 0){

        //Player Begin Jumping.
        player.physicsBody?.applyImpulse(CGVectorMake(0, 200))
        player.runAction(SKAction .playSoundFileNamed("sounds/Jump.caf", waitForCompletion: true))

    }

}

override func touchesEnded(touches: Set<NSObject>, withEvent event: UIEvent) {

    if (gameOver == 0){

        //Player End Jump.
        player.physicsBody?.applyImpulse(CGVectorMake(0, -120))

You can use the update-method. and in your touchesBegan-method you set a boolean or something like that to show the update-method that you are still pressing on the screen. For example:

//touchesBegan
touching = true

//update-method
if touching {
    player.physicsBody?.applyImpulse(CGVectorMake(0, 1))
}

//touchesEnded
touching = false

You have to change the applyImpulse so that it fits your needs.
