title: increase/decrease a number in Objective-C iOS
body: <p>Im new in xcode and programming for iOS.
  I have follow this tutorial:
  <a href="http://www.thetutorialblog.com/cocoa-objective-c/creating-a-basic-ipad-application/" rel="nofollow">http://www.thetutorialblog.com/cocoa-objective-c/creating-a-basic-ipad-application/</a></p>
  
  <p>I got it working with one "- button", one label and one "+ button".
  But i want multiple of those, i have add the tutorial code and copy it like this:</p>
  
  <pre><code>IBOutlet UILabel *currentNumber2;
  
  -(IBAction)incrementNumber2:(id)sender2;
  -(IBAction)decrementNumber2:(id)sender2;
  
  
  -(IBAction)incrementNumber2:(id)sender2 {
      number++;
      [currentNumber2 setText:[NSString stringWithFormat:@"%d", number]];
  }
  
  
  -(IBAction)decrementNumber2:(id)sender2 {
      number--;
      [currentNumber2 setText:[NSString stringWithFormat:@"%d", number]];
  }
  </code></pre>
  
  <p>But when I press the first + button, it count up +1 in first label, then when I press the second + button, it continue counting from first button in label2 so it put in 2. Understand?</p>
