Answer 1

Swift Solution

override func viewWillTransitionToSize(size: CGSize, withTransitionCoordinator coordinator: UIViewControllerTransitionCoordinator) {
    if UIDevice.currentDevice().orientation.isLandscape.boolValue {
        print("Landscape")
        view.endEditing(true)
    } else {
        print("Portrait")
        view.endEditing(true)
    }
}

Objective-C Solution

[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];

if ( ([[UIDevice currentDevice] orientation] ==  UIDeviceOrientationPortrait)  )
{
   // do something for Portrait mode
  [[self view] endEditing:YES];
}
else if(([[UIDevice currentDevice] orientation] == UIDeviceOrientationLandscapeRight) || ([[UIDevice currentDevice] orientation] == UIInterfaceOrientationLandscapeLeft))
{
   // do something for Landscape mode
   [[self view] endEditing:YES];
}

Answer 2

I used view.frame.width for auto-layout constraints.

bubbleWidthAnchor = bubbleView.widthAnchor.constraintEqualToConstant(view.frame.width/5*3)

like this.

Instead of that

bubbleWidthAnchor = bubbleView.widthAnchor.constraintEqualToConstant(UIScreen.mainScreen().bounds.width/5*3)

and it looks fine.
