How it works...
Whenever the user taps on the screen, a delegate method of
UIResponder
is called.
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent
*)event

}
In this method, the position of the touch is converted into local coordinates of
SKScene
.
Based on the location detected, it is compared to the spaceship location and up or down ac-
