Features

Demo

Requirements

Swift 4.2
iOS 10.0+
Xcode 9.x

Installation

Cocoapods

CocoaPods is a dependency manager for Cocoa projects.

To integrate WeScan into your Xcode project using CocoaPods, specify it in your Podfile:

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:

$ pod install

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:

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.

Usage

Swift

Ensure your view controller conforms to the ImageScannerControllerDelegate protocol:

class YourViewController: UIViewController, ImageScannerControllerDelegate {
    // YourViewController code here
}

Implement the delegate functions inside your view controller:

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)
}

Finally, create and present a ImageScannerController instance somewhere within your view controller:

let scannerViewController = ImageScannerController()
scannerViewController.imageScannerDelegate = self
present(scannerViewController, animated: true)

Objective-C

Create a dummy swift class in your project. When Xcode asks if you'd like to create a bridging header, press 'Create Bridging Header'
In the new header, add the Objective-C class (#import myClass.h) where you want to use WeScan
In your class, import the header (import <yourProjectName.swift.h>)
Drag and drop the WeScan folder to add it to your project
In your class, add @Class ImageScannerController;

Example Implementation

ImageScannerController *scannerViewController = [ImageScannerController new];
[self presentViewController:scannerViewController animated:YES completion:nil];
