Installation

CocoaPods

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

pod 'NotificationBannerSwift'

Then add import NotificationBannerSwift at the top of each file you use NotificationBanner in your project.

Carthage

To use NotificationBanner via Carthage simply add this line to your Cartfile:

github "Daltron/NotificationBanner" "master"

Then add NotificationBanner.framework and the dependencies SnapKit.framework and MarqueeLabelSwift.framework in your project.

Usage

Creating drop down alerts with NotificationBanner is easy. To create and show a banner, simply:

let banner = NotificationBanner(title: title, subtitle: subtitle, style: .success)
banner.show()

To create a status bar alert, simply:

let banner = StatusBarNotificationBanner(title: title, style: .success)
banner.show()

By default, each banner will be displayed on the main application window. If you are wanting to show a banner below a navigation bar, simply show on the view controller that is within the navigation system:

banner.show(on: viewController)

By default, each banner will present from the top. If you are wanting to display from the bottom, simply:

banner.show(bannerPosition: .bottom)

Each of the show properties defined above can be mixed and matched to work flawlessly with eachother.

By default, each banner will automatically dismiss after 5 seconds. To dismiss programatically, simply:

banner.dismiss()

To show a banner infinitely until it is manually dismissed, simply:

banner.autoDimiss = false

NotificationBanner has five prebuilt styles that you can choose from:

public enum BannerStyle {
    case danger
    case info
    case none
    case success
    case warning
}

You can override the predefined colors that NotificationBanner uses for any style by conforming to the BannerColorsProtocol:

public protocol BannerColorsProtocol {
    func color(for style: BannerStyle) -> UIColor
}

Its as easy as creating a custom banner colors class:

class CustomBannerColors: BannerColorsProtocol {

    internal override func color(for style: BannerStyle) -> UIColor {
        switch style {
            case .danger:   // Your custom .danger color
            case .info:     // Your custom .info color
            case .none:     // Your custom .none color
            case .success:  // Your custom .success color
            case .warning:  // Your custom .warning color
        }
    }

}

And then passing in that class to any notification banner you create:

let banner = NotificationBanner(title: title, style: .success, colors: CustomBannerColors())
banner.show()

By default, the .info style will be applied to the banner if no style is provided in the init method. You can set the background color of a banner at any time by simply setting the backgroundColor.

Banners with Side Views

A notification banner can have a left acessory view, a right acessory view, or both:

// Success Style Notification with Left View
let leftView = UIImageView(image: #imageLiteral(resourceName: "success"))
let banner = NotificationBanner(title: title, subtitle: subtitle, leftView: leftView, style: .success)
banner.show()

 // Danger Style Notification with Right View
let rightView = UIImageView(image: #imageLiteral(resourceName: "danger"))
let banner = NotificationBanner(title: title, subtitle: subtitle, rightView: rightView, style: .danger)
banner.show()    

// Info Style Notification with Left and Right Views
let leftView = UIImageView(image: #imageLiteral(resourceName: "info"))
let rightView = UIImageView(image: #imageLiteral(resourceName: "right_chevron"))
let banner = NotificationBanner(title: title, subtitle: subtitle, leftView: leftView, rightView: rightView, style: .info)
banner.show()

Banners with Side Views

Each side view will be automically reisized to fit perfectly

Banners with a Custom View

A notification banner can also be initalized with a custom view:

let banner = NotificationBanner(customView: NorthCarolinaBannerView())
banner.show()

Custom Banner

Handling User Interaction

By default, when a banner is tapped or swiped up by a user, it will be dismissed. If you want to detect when the user taps or swipes up on a banner, simply:

banner.onTap = {
    // Do something regarding the banner
}
banner.onSwipeUp = {
    // Do something regarding the banner
}

Banner Events

You can choose to opt into a notification banner’s events by registering as its delegate:

banner.delegate = self

Then just make sure to implement the following methods:

internal func notificationBannerWillAppear(_ banner: BaseNotificationBanner)
internal func notificationBannerDidAppear(_ banner: BaseNotificationBanner)
internal func notificationBannerWillDisappear(_ banner: BaseNotificationBanner)
internal func notificationBannerDidDisappear(_ banner: BaseNotificationBanner)

Haptic Feedback Support

By default, when a banner is displayed, a haptic feedback will be generated on devices that support it. The types of haptic feedback are as follows:

public enum BannerHaptic {
    case light
    case medium
    case heavy
    case none
}

To change the type of haptic feedback to generate when a banner is shown, simply:

banner.haptic = .heavy

Banner Queue

By default, each notification banner is placed onto a NotificationBannerQueue. This allows an infinite amount of banners to be de displayed without one hiding the other. By default, each notification banner is placed on the back of the queue. If you would rather place the banner in the front and show it immediately no matter how many banners are in the queue, simply state it in the show() method:

banner.show(queuePosition: .front)

Adding a banner to the front of the queue will temporarily suspend the currently displayed banner (if there is one) and will resume it after the banner in front of it dismisses.

To get the number of banners currently on the queue, simply:

let numberOfBanners = NotificationBannerQueue.default.numberOfBanners

This is all automatically managed!

Feature Requests
