📲 How to Install

Using CocoaPods

Edit your Podfile and specify the dependency:

pod 'MLBusinessComponents'

🐒 How to use

1 - Import into project.

import MLBusinessComponents

2 - Use your UI component.

Choose and instantiate your component.

📦 COMPONENTS

Each component is a subclass of UIView.

1️⃣ - MLBusinessLoyaltyRingView Component

This component allow you to show the progress ring of points, a label and actionable button. The most common use of this component is to show a user's progress within the loyalty program.

Visual Example:

MLBusinessLoyaltyRingView

MLBusinessLoyaltyRingView init

You need to set MLBusinessLoyaltyRingData protocol (interfase). This protocol allow you to populate the draw data into component. (Ring progress percent, ring color, label text, button title and button deeplink).

let ringView = MLBusinessLoyaltyRingView(_ ringViewData: MLBusinessLoyaltyRingData)
view.addSubView(ringView)

/* 
    Set your constraints. You don't need to set up the HEIGHT contraint. 
    Because this component is responsible for knowing and setting your own HEIGHT.
*/
NSLayoutConstraint.activate([
    ringView.leadingAnchor.constraint(equalTo: view.leadingAnchor),
    ringView.trailingAnchor.constraint(equalTo: view.trailingAnchor),
    ringView.topAnchor.constraint(equalTo: view.topAnchor)
])

MLBusinessLoyaltyRingData Protocol

This protocol allow you to providade the proper data to draw MLBusinessLoyaltyRingView. You can setup ring progress percent, ring color, label text, button title and button deeplink). Each value is mandatory.

Definition

@objc public protocol MLBusinessLoyaltyRingData: NSObjectProtocol {
    @objc func getRingHexaColor() -> String
    @objc func getRingNumber() -> Int
    @objc func getRingPercentage() -> Float
    @objc func getTitle() -> String
    @objc func getButtonTitle() -> String
    @objc func getButtonDeepLink() -> String
}

Implementation Example

Implementation of MLBusinessLoyaltyRingData example:

class MyDrawDataForRingView: NSObject, MLBusinessLoyaltyRingData {
    func getRingNumber() -> Int {
        return 3
    }

    func getRingHexaColor() -> String {
        return "#17aad6"
    }

    func getRingPercentage() -> Float {
        return 0.80
    }

    func getTitle() -> String {
        return "Ganaste 100 Mercado Puntos"
    }

    func getButtonTitle() -> String {
        return "Mis beneficios"
    }

    func getButtonDeepLink() -> String {
        return "mercadopago://beneficios"
    }
}

How to receive tap action and button deeplink?

You can be informed when the user presses the button of the component and receive the deeplink previously sent in MLBusinessLoyaltyRingData. Just add tapAction callback.

let ringView = MLBusinessLoyaltyRingView(MyDrawDataForRingView())
view.addSubView(ringView)

// Add tap action and receive the deepLink
ringView.addTapAction { deepLink in
    print(deepLink)
}

2️⃣ - MLBusinessDiscountBoxView Component

This component allow you to show a group of N items in a grid system (3 cols by default). You can add a title and subtitle for the main component. Also, you can provide imageUrl, title and subtitle for each item. This component is responsible for knowing and setting your own height based on number of cols and item quantity.

Visual Example:

MLBusinessDiscountBoxView

MLBusinessDiscountBoxView init

You need to set MLBusinessDiscountBoxData protocol. This interface allow you to populate the draw data into component. (Title, subtitle for the main component and imageUrl. Title, subtitle, deepLinkItem and trackId for each item).

// DiscountData() is an implementation of MLBusinessDiscountBoxData protocol.
let discountView = MLBusinessDiscountBoxView(DiscountData())
view.addSubview(discountView)

/* 
    Set your constraints. You don't need to set up the HEIGHT contraint. 
    Because this component is responsible for knowing and setting your own HEIGHT.
*/
NSLayoutConstraint.activate([
   discountView.leadingAnchor.constraint(equalTo: view.leadingAnchor),
   discountView.trailingAnchor.constraint(equalTo: view.trailingAnchor),
   discountView.topAnchor.constraint(equalTo: targetView.bottomAnchor)
])

MLBusinessDiscountBoxData Protocol

This protocol allow you to providade the proper data to draw MLBusinessDiscountBoxView. You can setup title and subtitle for the main component and a list of MLBusinessDiscountSingleItemProtocol that represent each element of the cell.

Definition

@objc public protocol MLBusinessDiscountBoxData: NSObjectProtocol {
    @objc optional func getTitle() -> String?
    @objc optional func getSubtitle() -> String?
    @objc func getItems() -> [MLBusinessSingleItemProtocol]
}

Implementation of MLBusinessDiscountBoxData in DiscountData example:

class DiscountData: NSObject, MLBusinessDiscountBoxData {
    func getTitle() -> String {
        return "200 descuentos"
    }

    func getSubtitle() -> String {
        return "por ser nivel 3"
    }

    func getItems() -> [MLBusinessSingleItemProtocol] {
        var array: [MLBusinessSingleItemProtocol] = [MLBusinessSingleItemProtocol]()
        array.append(SingleItemData(title: "Hasta", subtitle: "$ 200", iconImageUrl: "https://upload.wikimedia.org/wikipedia/commons/thumb/3/36/McDonald%27s_Golden_Arches.svg/1200px-McDonald%27s_Golden_Arches.svg.png"))
        array.append(SingleItemData(title: "Hasta", subtitle: "$ 200", iconImageUrl: "https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcRY0eFECzyTCa83gOV3smCYDOSIggdUxSPirwtt5rS3LcWlzefo"))
        array.append(SingleItemData(title: "Hasta", subtitle: "$ 200", iconImageUrl: "https://upload.wikimedia.org/wikipedia/commons/b/b3/Logo-freddo.jpg"))
        array.append(SingleItemData(title: "Hasta", subtitle: "$ 200", iconImageUrl: "https://urbancomunicacion.com/wp-content/uploads/2017/04/Logotipos-famosos-Starbucks-Urban-comunicacion-1.png"))
        array.append(SingleItemData(title: "Hasta", subtitle: "$ 200", iconImageUrl: "https://www.stickpng.com/assets/images/5a1c3211f65d84088faf13e8.png"))
        array.append(SingleItemData(title: "Hasta", subtitle: "$ 200", iconImageUrl: "https://pbs.twimg.com/profile_images/1124417403566395394/9Wuzg8pf.png"))
        return array
    }
}

SingleItem Protocol

This protocol/interfase represents the element of each cell for MLBusinessDiscountBoxView. Each element contains imageUrl, title, subtitle, deepLinkItem and trackId.

    init(title: String, subtitle: String, iconImageUrl: String, deepLink: String? = nil, trackId: String? = nil) {
        self.title = title
        self.subTitle = subtitle
        self.iconUrl = iconImageUrl
        self.deepLink = deepLink
        self.trackId = trackId
    }

        return title
    }

    func subtitleForItem() -> String {
        return subTitle
    }

    func iconImageUrlForItem() -> String {
        return iconUrl
    }

Where we can set the color with which it will expand
and an optional image that will be displayed on the button when it becomes circular.
*/

    func didFinishAnimation(_ animatedButton: MLBusinessAnimatedButton) {
        guard let navigationController = navigationController else { return }

        let newVC = UIViewController()
        newVC.view.backgroundColor = .red

        animatedButton.goToNextViewController(newVC, navigationController)
    }

    func progressButtonAnimationTimeOut() {
        print("TimeOut")
    }

    func expandAnimationInProgress() {
        navigationController?.setNavigationBarHidden(true, animated: true)
    }
}

🔠 Font and color customization.

We use MLUI open source library to customize accent colors and font labels. In order to change those values check the documentation of MLUI stylesheet protocol. https://github.com/mercadolibre/fury_mobile-ios-ui
