MRInAppPurchaseView

Simple tableView for display and interact with in-app purchases

Requirements

• iOS 13.0+
• Xcode 13.0+
• Swift 5.5+

Installation

Swift Package Manager

The Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the swift compiler. It is in early development, but MRInAppPurchaseView does support its use on supported platforms.

Once you have your Swift package set up, adding MRInAppPurchaseView as a dependency is as easy as adding it to the dependencies value of your Package.swift.

dependencies: [
    .package(url: "https://github.com/furiosFast/MRInAppPurchaseView.git", from: "1.0.0")
]

Manually

If you prefer not to use any of the aforementioned dependency managers, you can integrate MRInAppPurchaseView into your project manually.

Usage

Example

import MRInAppPurchaseView
import SwifterSwift
import UIKit

class IAPViewController: MRInAppPurchaseView, MRInAppPurchaseViewDelegate {
    var IAPDataList: [InAppPurchaseData] = []
    
    override func viewDidLoad() {
        super.viewDidLoad()
        inAppPurchaseView.delegate = self
        
        inAppPurchaseView.setCellTitleFont(UIFont.systemFont(ofSize: 20))
    }
    
    override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)                
        setupInAppPurchaseData()
        
        DispatchQueue.global().async {
            if IAPManager.shared.products.count < IAPManager.shared.productIDS.count {
                IAPManager.shared.getProductInfo {
                    self.setupInAppPurchaseData()
                    
                    DispatchQueue.main.async {
                        self.inAppPurchaseView.reloadData()
                    }
                }
            }
        }
    }

    // MARK: - MRInAppPurchaseViewDelegate
    
    func inAppPurchaseButtonTapped(inAppPurchase: InAppPurchaseData) {
        let manager = IAPManager.shared
        
        if inAppPurchase.id == inAppId_proKit {
            proKit(manager)
        } else {
            restorePurchases(manager)
        }
    }
    
    // MARK: - Private functions
    
    private func setupInAppPurchaseData() {
        IAPDataList.removeAll()
        inAppPurchaseView.setInAppPurchases([])
        let manager = IAPManager.shared //your in-app data manager
        
        // pro kit
        if !PurchasedInApp.proKit.isPurchased {
            let data = InAppPurchaseData(inAppId_proKit, manager.productIcons[inAppId_proKit]!, loc("settings_PROKIT"), loc("settings_PROKITWIKI"), loc("inapp_BUY").uppercased())
            data.wikiTextAlignment = .left
            IAPDataList.append(data)
        }
        
        // restore
        let data = InAppPurchaseData("restore", #imageLiteral(resourceName: "restore in-app"), loc("settings_RESTOREINAPP"), nil, loc("inapp_RESTORE").uppercased())
        data.iconBorderColor = .clear
        IAPDataList.append(data)
        
        inAppPurchaseView.setInAppPurchases(IAPDataList)
    }
    
    // in-app products actions
    private func proKit(_ manager: IAPManager) {
        if manager.products.count != 0 {
            manager.purchaseProduct(productId: inAppId_proKit, completed: { message in
                if message.isEmpty {
                    self.showAlert(title: "Success", message: "PRO Kit purchased", buttonTitles: ["OK"])
                
                    self.setupInAppPurchaseData()
                    self.inAppPurchaseView.reloadData()
                } else {
                    if message != loc("inapp_UNKNOWERROR") {
                        self.showAlert(title: "Warning"), message: message, buttonTitles: ["OK"])
                    }
                }
                self.inAppPurchaseView.setNomalStateToPurchaseButtonsFromProgress()
            })
        } else {
            inAppPurchaseView.setNomalStateToPurchaseButtonsFromProgress()
        }
    }
    
    private func restorePurchases(_ manager: IAPManager) {
        if manager.products.count != 0 {
            manager.restorePurchases(completed: { [self] restoreMessage, purchase in
                if restoreMessage.isEmpty {
                    purchase.restoredPurchases.forEach { purchase in
                        switch purchase.productId {
                            case inAppId_proKit: do {
                                //do somethings...
                            default: break
                        }
                    }
                    
                    
                    self.setupInAppPurchaseData()
                    self.inAppPurchaseView.reloadData()
                    self.showAlert(title: "Success", message: loc("inapp_RESTORESUCCESS"), buttonTitles: ["OK"])
                } else {
                    self.showAlert(title: "Warning", message: restoreMessage, buttonTitles: ["OK"])
                }
                self.inAppPurchaseView.setNomalStateToPurchaseButtonsFromProgress()
            })
        } else {
            inAppPurchaseView.setNomalStateToPurchaseButtonsFromProgress()
        }
    }

And now open show 'inAppPurchaseView' from your ViewController

class ViewController: UIViewController {
    
    //MARK: - IBActions
    @IBAction func showIAPViewController(_ sender: Any) {
        let iapVC = IAPViewController()
        iapVC.navigationItem.title = loc("settings_INAPPHEADERTEXT")
        
        let navC = UINavigationController(rootViewController: iapVC)
        present(navC, animated: true)
    }

}

Requirements

MRInAppPurchaseView has different dependencies and therefore needs the following libraries (also available via SPM):

• SwifterSwift 5.1.0+

It isn't necessary to add the dependencies of MRInAppPurchaseView, becose with SPM all is do automatically!
