Part 8 - UIView's Tint Property

• Visually indicates which controls are active or have actions associated with them.
• Use tintColor in code to set Tint.
  Example:

   
  view.tintColor = UIColor.red
   
  

• Setting Tint on a UIView changes the tint for all subviews.
  Example:
  
• You can override Tint set by the parent UIView by setting Tint on the control.
• Globally set Tint in the AppDelegate.
  Example:

   
  var window: UIWindow?
  
  func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
      
      window?.tintColor = UIColor.purple
      
      return true
  }
   
  

• Globally set Tint through Storyboard.
  Example:
  
• The non-transparent parts of a UIImage can use the Tint color.
  Change the "Render As" property to "Template Image". Done from the image in the Assets.xcassets:
  
  
• Note: As of Xcode 8, the tint will only show on the image during run-time, not design-time on the StoryBoard.
