Installation

Requirements

To use the InAppPurchaseButton library, make sure your project meets the following requirements:

• iOS 10.0 or later
• Xcode 11.0 or later
• Swift 5.0 or later
• UIKit framework

Step 1: Cocoapods Installation

To integrate the InAppPurchaseButton library into your Xcode project, you can use Cocoapods, a popular dependency manager for iOS projects:

// Add the following line to your Podfile
pod 'InAppPurchaseButton'

// Then run the following command
pod install

Step 2: Manual Installation

If you prefer not to use Cocoapods, you can manually add the InAppPurchaseButton library to your project:

1. Download the latest release of the library from the GitHub page.
2. Unzip the downloaded file and locate the ‘InAppPurchaseButton.framework’ file.
3. In Xcode, select your project’s target and go to the ‘General’ tab.
4. Scroll down to the ‘Frameworks, Libraries, and Embedded Content’ section.
5. Drag and drop the ‘InAppPurchaseButton.framework’ file into the ‘Frameworks, Libraries, and Embedded Content’ section.
6. Make sure to select ‘Copy items if needed’ and choose ‘Create groups’ in the dialog that appears.

Step 3: Import and Initialization

Once you have installed the library, you need to import it and initialize the button in your project:

// Import the library
import InAppPurchaseButton

// Create an instance of InAppPurchaseButton
let purchaseButton = InAppPurchaseButton(frame: CGRect(x: 0, y: 0, width: 120, height: 40))


Usage

The InAppPurchaseButton library provides a straightforward way to handle in-app purchases in your app using a customizable button interface.

Step 1: Set Product Identifier

Before using the button, you must set the product identifier for the item you want to sell:

purchaseButton.productIdentifier = "com.yourdomain.yourapp.product"

Step 2: Customize Button Appearance

The library offers various customization options to match the button’s design to your app’s visual style. Here are some examples:

// Change button title
purchaseButton.setTitle("Buy Now", for: .normal)

// Customize button border
purchaseButton.layer.borderWidth = 1.0
purchaseButton.layer.borderColor = UIColor.black.cgColor

Step 3: Add Button Action

To initiate the purchase when the button is tapped, you need to add a target-action method:

// Example target-action method
@objc private func purchaseButtonTapped() {
// Handle the purchase logic here
// You can use the `purchaseButton.productIdentifier` to identify the bought item
}

Make sure to set the target-action for the button:

purchaseButton.addTarget(self, action: #selector(purchaseButtonTapped), for: .touchUpInside)

Example Code

Below is a complete example of how to use the InAppPurchaseButton in a sample app:

// Import the library
import InAppPurchaseButton

// Create an instance of InAppPurchaseButton
let purchaseButton = InAppPurchaseButton(frame: CGRect(x: 0, y: 0, width: 120, height: 40))

// Set product identifier
purchaseButton.productIdentifier = "com.yourdomain.yourapp.product"

// Customize button appearance
purchaseButton.setTitle("Buy Now", for: .normal)
purchaseButton.titleFont = UIFont.boldSystemFont(ofSize: 16)
purchaseButton.backgroundColor = .blue
purchaseButton.layer.cornerRadius = 8.0
purchaseButton.layer.borderWidth = 1.0
purchaseButton.layer.borderColor = UIColor.black.cgColor

// Add target-action method
@objc private func purchaseButtonTapped() {
    // Handle the purchase logic here
}

purchaseButton.addTarget(self, action: #selector(purchaseButtonTapped), for: .touchUpInside)

Conclusion

Congratulations! You have successfully learned the basics of using the InAppPurchaseButton library in your iOS app. You can now leverage its features to simplify in-app purchases and enhance the user experience of your application.
