It is in early development, but WeScan does support its use on supported platforms. Once you have your Swift package set up, adding WeScan as a dependency is as easy as adding it to the `dependencies` value of your `Package.swift`. ```swift dependencies: [ .package(url: "https://github.com/WeTransfer/WeScan.git", .upToNextMajor(from: "1.7.0")) ] ``` ### Cocoapods [CocoaPods](http://cocoapods.org) is a dependency manager for Cocoa projects. To integrate **WeScan** into your Xcode project using CocoaPods, specify it in your `Podfile`: ```rubygi source 'https://github.com/CocoaPods/Specs.git' platform :ios, '10.0' use_frameworks! target '<Your Target Name>' do pod 'WeScan', '>= 0.9' end ``` Then, run the following command: ```bash $ pod install ``` ### Carthage [Carthage](https://github.com/Carthage/Carthage) is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks. To integrate **WeScan** into your Xcode project using Carthage, specify it in your `Cartfile`: ```ogdl github "WeTransfer/WeScan" >= 0.9 ``` Run `carthage update` to build the framework and drag the built `WeScan.framework` into your Xcode project. ### Manually Just download the project, and drag and drop the "WeScan" folder in your project. <p align="center"> <img width="900px" src="Assets/project.png"> </p> Simply add the WeScan framework in the project's Embedded Binaries and Linked Frameworks and Libraries. <p align="center"> <img width="900px" src="Assets/LinkedFrameworks.png"> </p> ## Usage ### Swift 1. In order to make the framework available, add `import WeScan` at the top of the Swift source file 2. In the Info.plist, add the `NSCameraUsageDescription` key and set the appropriate value in which you have to inform the user of the reason to allow the camera permission 3. Make sure that your view controller conforms to the `ImageScannerControllerDelegate` protocol: ```swift class YourViewController: UIViewController, ImageScannerControllerDelegate { // YourViewController code here } ``` 4. Implement the delegate functions inside your view controller: ```swift func imageScannerController(_ scanner: ImageScannerController, didFailWithError error: Error) { // You are responsible for carefully handling the error print(error) } func imageScannerController(_ scanner: ImageScannerController, didFinishScanningWithResults results: ImageScannerResults) { // The user successfully scanned an image, which is available in the ImageScannerResults // You are responsible for dismissing the ImageScannerController scanner.dismiss(animated: true) } func imageScannerControllerDidCancel(_ scanner: ImageScannerController) { // The user tapped 'Cancel' on the scanner // You are responsible for dismissing the ImageScannerController scanner.dismiss(animated: true) } ``` 5. Finally, create and present a `ImageScannerController` instance somewhere within your view controller: ```swift let scannerViewController = ImageScannerController() scannerViewController.imageScannerDelegate = self present(scannerViewController, animated: true) ``` ### Objective-C 1. Create a dummy swift class in your project. When Xcode asks if you'd like to create a bridging header, press 'Create Bridging Header' 2. In the new header, add the Objective-C class (`#import myClass.h`) where you want to use WeScan 3. In your class, import the header (`import <yourProjectName.swift.h>`) 4. Drag and drop the WeScan folder to add it to your project 5. In your class, add `@Class ImageScannerController;` #### Example Implementation ```objc ImageScannerController *scannerViewController = [[ImageScannerController alloc] init]; [self presentViewController:scannerViewController animated:YES completion:nil]; ``` <br> ## Contributing As the creators, and maintainers of this project, we're glad to invite contributors to help us stay up to date.
