title: Use different force with UITouch in objective-c and 3dtouch
body: <p>I'm trying include a force component in my objective c code as it should now be possible since ios9. 
  my code contains the following 2 methods:</p>
  
  <pre><code>- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
  
  - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
  </code></pre>
  
  <p>in the touchesEnded method I'm trying to get the force of the touch event with the following lines of code:</p>
  
  <pre><code>for (UITouch *touch in touches) {
      CGFloat force = touch.force;
      CGFloat percentage = force/touch.maximumPossibleForce;
      NSLog(@"Printing force : %f", force);
      NSLog(@"Printing percentage: %f", percentage);
      NSLog(@"Printing maximum possible force: %f",    touch.maximumPossibleForce);
      break;
  }
  </code></pre>
  
  <p>I'm trying to run my code on an iphone 6s and I get extremely weird and contradicting values, e.g. 
      force : 2.650000 
  and 
      force : 0.066667
  even though I think I'm pressing the buttons almost with equal force.</p>
  
  <p>i do not want to implement peek and pop but just let users control the app with different options in one button.</p>
  
  <p>thank you very much in advance!</p>
