RSBarcodes Build Status

RSBarcodes allows you to scan 1D and 2D barcodes using metadata scanning capabilities introduced with iOS7 and generate the same set of barcode images for displaying and sharing. PR from MacMannes has been merged to make a part of code generators working on iOS5.1 above.

Installation

CocoaPods is the recommended method of installing RSBarcodes.

Simply add the following line to your Podfile:

pod 'RSBarcodes', '~> 0.1.4'

Or you can use the RSBarcodes framework without import all headers files.

Just imports these frameworks:

RSBarcodes.framework (it’s under the product folder of this project) :)
AVFoundation.framework
CoreImage.framework
CoreGraphics.framework

When you use the framework you must import the headers like below:

#import <RSBarcodes/aHeader.h>

RSCodeView.h and RSCodeGen.h are already imported into the RSBarcodes.h so you can use directly

#import <RSBarcodes/RSBarcodes.h>

Thanks to g8production www.g8production.com github for providing this.

Usage

Barcode Scanner:

Option 1:

Create RSScannerViewController from code an present it. Use the callback block to process the barcode.

(id)initWithCornerView:(BOOL)showCornerView controlView:(BOOL)showControlsView barcodesHandler:(RSBarcodesHandler)barcodesHandler;
(id)initWithCornerView:(BOOL)showCornerView controlView:(BOOL)showControlsView barcodesHandler:(RSBarcodesHandler)barcodesHandler preferredCameraPosition:(AVCaptureDevicePosition)cameraDevicePosition;

You can add borders to the button with: [scanner setIsButtonBordersVisible:YES];
You can automatically stop the processing after the first vaild barcode with [scanner setStopOnFirst:YES];
After that you can either dismiss it, or restart it with [scanner __startRunning];

possible Device Positions: AVCaptureDevicePositionBack, AVCaptureDevicePositionFront

RSScannerViewController *scanner = [[RSScannerViewController alloc] initWithCornerView:YES
                                                                           controlView:YES
                                                                           barcodesHandler:^(NSArray *barcodeObjects) {
                                                                       }
                                                               preferredCameraPosition:AVCaptureDevicePositionBack];

The ViewController can be presented modally:
[self presentViewController:scanner animated:true completion:nil];
or pushed onto a NavigationController Stack:
[self.navigationController pushViewController:scanner animated:YES];

Option 2:

Place a UIViewController in storyboard and set RSScannerViewController based class as its custom class. If you want to use the corners view (for barcode corners and borders displaying), you can put a UIView onto the view controller’s view and set RSCornersView as its custom class then link the highlightView to it, make sure the view’s size is as large as the view controller’s view.

In RSScannerViewController based class implements your own handler.

- (id)initWithCoder:(NSCoder *)aDecoder
{
    self = [super initWithCoder:aDecoder];
    if (self) {
        __weak typeof(self) weakSelf = self;
        self.barcodesHandler = ^(NSArray *barcodeObjects) {
        };
        self.tapGestureHandler = ^(CGPoint tapPoint) {
        });
    }
    return self;
}

Barcode Generators:

Import RSCodeGen.h into your source file and using CodeGen to generate barcode image. RSBarcodes provides 2 ways.

@protocol RSCodeGenerator <NSObject>

- (UIImage *)genCodeWithMachineReadableCodeObject:(AVMetadataMachineReadableCodeObject *)machineReadableCodeObject;

- (UIImage *)genCodeWithContents:(NSString *)contents machineReadableCodeObjectType:(NSString *)type;

@end

Here are examples, the generated image could be used along with RSCodeView or UIImageView.

[CodeGen genCodeWithContents:<#(NSString *)#> machineReadableCodeObjectType:<#(NSString *)#>] // Types are coming from AVMetadataObject.h and RSCodeGen.h

or

[CodeGen genCodeWithMachineReadableCodeObject:<#(AVMetadataMachineReadableCodeObject *)#>]
