Simple view that has super simple API and behaves similar to iOS 11 notifications, so you can use it inside the app.
How does it look ?
To show a notification view use class method [NVNotificationView showNotificationWithTitle:andMessage:], it will show the notification view in your root ViewController. Also, you may use [NVNotificationView showNotificationWithTitle:andMessage:inViewController:] to show it in the concrete ViewController. Both these methods return a new instance of NVNotificationView.
View is automatically closed in the 3 seconds or you can dismiss it with swipe it up. Also, you can dismiss it programatically using hide:(BOOL)animated method.
