title: Unable to simultaneously satisfy constraints after dialing number programatically
body: <p>I have made a simple app that contains a view where the user can call a number. It contains a lable, a textview and a button. These are contained vertically inside a stack view. There are total three (3) constraints:</p>
  
  <ol>
  <li>Center stack view vertically</li>
  <li>Center stack view horizontally</li>
  <li>Make the with of the text view equal to the with of the stack view</li>
  </ol>
  
  <p>When pressing the button, the number in the textview is called using this code:</p>
  
  <pre><code>let phoneNumber = "telprompt:\(numberToDial)"
  UIApplication.sharedApplication().openURL(NSURL(string: phoneNumber)!)
  </code></pre>
  
  <p>As soon as the system phone calling screen appears, I get autolayout errors that I just feel like I don't have anything to do with. The two autolayout constraint below is what is causing the errors:</p>
  
  <pre><code>(
  "&lt;NSLayoutConstraint:0x10187a9b0 V:|-(20)-[UIInputSetContainerView:0x101878f10]   (Names: '|':UITextEffectsWindow:0x1018765c0 )&gt;",
  "&lt;NSLayoutConstraint:0x1007b21a0 'UIInputWindowController-top' V:|-(0)-[UIInputSetContainerView:0x101878f10]   (Names:'|':UITextEffectsWindow:0x1018765c0 )&gt;"
  )
  </code></pre>
  
  <p>Why am I getting these errors? The app works exactly like I want it to, I just get these errors that I don't like.</p>
  
  <p>EDIT:
  It is not the same problem as the status bar one. I found it and added that code to my app delegate but I still get this error. This code is in my app delegate:</p>
  
  <pre><code>func application(application: UIApplication, willChangeStatusBarFrame    newStatusBarFrame: CGRect) {
      for window in UIApplication.sharedApplication().windows {
          if window.dynamicType.self.description().containsString("UITextEffectsWindow") {
              window.removeConstraints(window.constraints)
          }
      }
  }
  </code></pre>
  
  <p>EDIT2:
  I forgot to write that the view making the call is inside a UITabBarController.</p>
