Getting Started

There is an example project inside the source code. You are suggested to have a look first and get familiar with this framework.

The Basics

This is the basic function with all default settings, design your own UIView or use CFNotifyView to create one easily.

CFNotify.present(view: UIView)

If you need more custom settings, create your own Config and use the following function.

CFNotify.present(config: Config, view: UIView)

if you want custom tap action, use the following function. (If you use tapHandler, it will override the default tap to hide action)

CFNotify.present(config: Config, view: UIView, tapHandler: (()->Void)?)

CFNotify will put all the views to be shown in queue (First In First Out).
You can hide the view programmatically using the following functions.

CFNotify.hide() // hide the current view

CFNotify.hideAll() // hide all the views in queue (Clear the queue)


You can create an alert view quickly and easily by using CFNotifyView class.

CFNotifyView included 3 views currently: Cyber, Classic, Toast.

Each style has 4 themes: Info, Success, Fail, Warning

Each theme has 2 styles: Light and Dark

  • Cyber

    // Use Pre-set theme
    let cyberView = CFNotifyView.cyberWith(title: "Title",
                                            body: "Body",
                                           theme: .info(.light))
    //More customizations
    let customCyberView = CFNotifyView.cyberWith(titleFont: UIFont,
                                                titleColor: UIColor,
                                                  bodyFont: UIFont,
                                                 bodyColor: UIColor,
                                           backgroundColor: UIColor,
                                                 blurStyle: UIBlurEffectStyle)
  • Classic

    // Use Pre-set theme
    let classicView = CFNotifyView.classicWith(title: "Title",
                                                body: "Body",
                                               theme: .success(.light))
    //More customizations
    let customClassicView = CFNotifyView.classicWith(titleFont: UIFont,
                                                    titleColor: UIColor,
                                                      bodyFont: UIFont,
                                                     bodyColor: UIColor,
                                               backgroundColor: UIColor)
  • Toast

    // Use Pre-set theme
    let toastView = CFNotifyView.toastWith(text: "Text",
                                          theme: .fail(.dark))
    //More customizations
    let customToastView = CFNotifyView.toastWith(text: String,
                                             textFont: UIFont,
                                            textColor: UIColor,
                                      backgroundColor: UIColor)                                    


You can config CFNotify using Config class. Config class included lots of properties, the following three are the most common:

  • initPosition : where the view is born
  • appearPosition : where the view appear position
  • hideTime : the view will automatically hide after hideTime (default is 3 sec)


var classicViewConfig = CFNotify.Config()
classicViewConfig.initPosition = .top(.random) //the view is born at the top randomly out of the boundary of screen
classicViewConfig.appearPosition = .top //the view will appear at the top of screen
classicViewConfig.hideTime = .never //the view will never automatically hide


CFNotify provides Delegate methods for some of common events.
You need to conform to the CFNotifyDelegate.

func cfNotifyDidAppear() {}

func cfNotifyStartDragging(atPoint: CGPoint) {}

func cfNotifyIsDragging(atPoint: CGPoint) {}

func cfNotifyEndDragging(atPoint: CGPoint) {}

func cfNotifyDidDisappear() {}

func cfNotifyIsTapped() {}

To-Do List

  • [ ] Improve the example app
  • [ ] Add alert view with buttons
  • [ ] Full documentation
