title: Some part of the screen is not clickable in SWIFT
body: <p>I have a nested UIview under my view controller (landscape mode) that holds 2 buttons.
  The first button is placed on the left side of the screen and the second button is located at the right most. I'm just wondering why only 1/4 part of the 2nd button is working. I re-arranged that button on the 0 axis and it worked well.</p>
  
  <p>I think there's something wrong on the frame that I passed on the uiview.
  Please see my code.</p>
  
  <p>import UIKit</p>
  
  <p>class ViewController: UIViewController {</p>
  
  <pre><code>var screenHolder:ScreenHolder?
  override func viewDidLoad() {
      super.viewDidLoad()
      // Do any additional setup after loading the view, typically from a nib.
      ProjectData.currentFrame = self.view.frame
      screenHolder = ScreenHolder(frame: ProjectData.currentFrame)
      self.view.addSubview(screenHolder!)
  }
  
  override func didReceiveMemoryWarning() {
      super.didReceiveMemoryWarning()
      // Dispose of any resources that can be recreated.
  }
  </code></pre>
