Example

Requirements

Requires iOS SDK version > 8.0

Installation

EVWDropDownNotification is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod "EVWDropDownNotification"

Usage

First import the "EVWDropDownNotification" module:

import EVWDropDownNotification

Then extend your ViewController with the "EVWDropDownNotificationDelegate" and initialise a class variable of type "EVWDropDownNotification":

class ViewController: UIViewController, EVWDropDownNotificationDelegate {

let notification = EVWDropDownNotification()
...

Implement the 3 Delegate Methods:

func dropdownNotificationBottomButtonTapped() {
  //Do something
  ...
  //Dismiss the notification view
  notification.dismissWithGravityAnimation(true)
}
    
func dropdownNotificationTopButtonTapped() {
  //Do something
  ...
  //Dismiss the notification view
  notification.dismissWithGravityAnimation(true)
}
    
func dropdownNotificationDismissedWithTap() {
  //Do something
  ...
  // !!!!! NO NEED TO DISMISS THE NOTIFICATION VIEW !!!!!
}

In your ViewDidLoad set the Properties for the Notification (see below for all available properties):

  notification.delegate = self
  notification.image = UIImage(named: "notification")
  notification.bottomButtonText = "Accept"
  notification.topButtonText = "Cancel"
  notification.dismissOnTap = false
  notification.buttonVerticalAligment = .Bottom
  notification.titleText = "Title Here"
  notification.subtitleText = "Message Here"

Once all properties set, call the following function to display the Notfication:

 /*
 * NOTE: always provide the ViewController (self.view.Superview) as first parameter
 */
 notification.presentInView(self.view.superview!, withGravityAnimation: true)
