Inspired by the Tutorial from Appcoda: [AppCoda](http://www.appcoda.com/qr-code-reader-swift/). 3 | 4 | ## Installation 5 | 6 | ROBarcodeScanner is available through [CocoaPods](http://cocoapods.org). To install 7 | it, simply add the following line to your Podfile: 8 | 9 | ```ruby 10 | pod "ROBarcodeScanner" 11 | ``` 12 | 13 | ## How to use 14 | 15 | The ROBarcodeScannerViewController is a predefined view for the scanning. It shows the video and a result label on the bottom of the screen. When it detects an accepted barcode it does mark the barcode in the video window with green border. With a tap on the screen the user can confirm that the correct barcode was scanned and the callback is called. 16 | 17 | ![ROBarcodeScanner Example](https://raw.githubusercontent.com/prine/ROBarcodeScanner/master/Screenshot.png) 18 | 19 | ```swift 20 | var barcodeScanner:ROBarcodeScannerViewController? 21 | 22 | // Define the callback which handles the returned result 23 | barcodeScanner?.barcodeScanned = { (barcode:String) in 24 | // The scanned result can be fetched here 25 | println("Barcode scanned: \(barcode)") 26 | } 27 | 28 | // Push the view 29 | if let barcodeScanner = self.barcodeScanner { 30 | self.navigationController?.pushViewController(barcodeScanner, animated: true) 31 | } 32 | 33 | ``` 34 | 35 | ## License 36 | 37 | ``` 38 | The MIT License (MIT) 39 | 40 | Copyright (c) 2019 Robin Oster (http://prine.ch) 41 | 42 | Permission is hereby granted, free of charge, to any person obtaining a copy of 43 | this software and associated documentation files (the "Software"), to deal in 44 | the Software without restriction, including without limitation the rights to 45 | use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of 46 | the Software, and to permit persons to whom the Software is furnished to do so, 47 | subject to the following conditions: 48 | 49 | The above copyright notice and this permission notice shall be included in all 50 | copies or substantial portions of the Software. 51 | 52 | THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR 53 | IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS 54 | FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
