The QRCodeReader.swift is a simple QRCode Reader/Scanner based on the AVFoundation framework from Apple written in swift. It aims to replace ZXing or ZBar for iOS 8 and over.
It also allows you to switch between the front and the back cameras.
Download the project and copy the QRCodeReader folder into your project to use it in.
// Good practive: create the reader lazily to avoid cpu overload during the
// initialization and each time we need to scan a QRCode
lazy var reader: QRCodeReader = QRCodeReader(cancelButtonTitle: "Cancel")
@IBAction func scanAction(sender: AnyObject) {
// Retrieve the QRCode content
// By using the delegate pattern
reader.delegate = self
// Or by using the closure pattern
reader.completionBlock = { (result: String?) in
println(result)
}
// Presents the reader as modal form sheet
reader.modalPresentationStyle = .FormSheet
presentViewController(reader, animated: true, completion: nil)
}
// MARK: - QRCodeReader Delegate Methods
func reader(reader: QRCodeReader, didScanResult result: String) {
self.dismissViewControllerAnimated(true, completion: nil)
}
func readerDidCancel(reader: QRCodeReader) {
self.dismissViewControllerAnimated(true, completion: nil)
