title: How to remove a child SKSpritenode from SKNode?
body: <p>i will explain a part of my code. I have Spritenodes (images) who are moving down on the screen. </p>
  
  <pre><code>SKTexture* Squaretexture = [SKTexture textureWithImageNamed:@"squaregreen"];
  SquareTexture.filteringMode = SKTextureFilteringNearest;
  Square = [SKSpriteNode spriteNodeWithTexture:SquareTexture];
  Square.name = @"square";
  .
  .
  .
  
  [_objects addChild:Square];
  </code></pre>
  
  <p><code>_objects</code> is a <code>SKNode</code> and <code>Square</code> is a <code>SKSpriteNode</code>. Now there is my code: every one second  there is one square, who came from "over the screen" and is moving to the bottom. (Also there are more then one squares on the screen).</p>
  
  <p>Now I want this: When I touch a square it should be "deleted" or hidden, but only the one who i touch. With my code, when i touch all squares are deleted or nothing. I tried with removefromparent and removechild, but i couldn't solve it.</p>
  
  <pre><code>-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
      /* Called when a touch begins */
  
      UITouch *touch = [touches anyObject];
      CGPoint location = [touch locationInNode: self];
      SKNode *node = [self nodeAtPoint:location];
  
      NSLog(@"Point in myView: (%f,%f)", location.x, location.y);
      if ([node.name isEqualToString:@"Square"]) {
          [Square removeFromParent];
          [Square removeAllChildren];
      }    
  }
  </code></pre>
  
  <p>Do you have a suggestion how can I do it?
  Thanks for Answers.
