QRCodeScan

A simple QR Code scan solution with only system API and smooth animation.

Usage

Copy the source code in the /QRCodeScan folder into your project, then use it like UIViewController. Please check details in Demo project.

Create the QRCodeScanViewController and present it:

    QRCodeScanViewController *scanViewController = [[QRCodeScanViewController alloc] init];
    scanViewController.continuous = YES;
    scanViewController.scanInterval = 1.5;
    scanViewController.delegate = self;
    [self presentViewController:scanViewController animated:YES completion:nil];

    //Other customizations
    //scanViewController.scanWindowCornerColor = UIColor.redColor;
    //scanViewController.scanWindowFrame = CGRectMake(100, 100, 100, 100);
    //scanViewController.textAboveScanWindow = @"Scan QRcode";
    //scanViewController.textAboveScanWindowMargin = 20.0;
    
    //Could be pushed by an UINavigationController
    //[self.navigationController pushViewController:scanViewController animated:YES];

Handle the QRCode scanned:

#pragma mark - QRCodeScanViewControllerDelegate
-(void)QRCodeScanViewController:(QRCodeScanViewController *)qrCodeScanViewController qrCodeDidScanned:(NSString *)qrCode {
    NSLog(@"QRCode Scanned:%@",qrCode);

    //Usually, we dismiss the QRCodeScanViewController after QRCode scanned
    [qrCodeScanViewController dismissViewControllerAnimated:YES completion:nil];
}

Customization

The scan time interval, continuous scanning, scan window corner color and its frame could be customed.
