MPQRCoreSDK

This SDK provides parser for parsing Push Payment QR code.

You can use this SDK to generate Push Payment QR code string also by filling the data and using PushPaymentData.generatePushPaymentString(). See documentation for more information.

This sdk only deals with actual QR code strings. So you need to use a separate QR scanning SDK to get QR code strings. You can use MPQRScanSDK

This SDK is developed in Objective-C and it works with Swift.

Requirements:

1. Xcode 9.0+
2. iOS 8.0+

Features:

1. Capabilities to parse and validate Push Payment QR code string.
2. Generate Push Payment QR code string.

Documentation

The code documentation can be found on Github link [here][3].

Installation

Cocoapods

• In your Podfile write the following

  use_frameworks!
  pod 'MPQRCoreSDK'
  

• Do pod install

• Everything is setup now

Manual

Swift

• Download the latest release of MPQRCoreSDK.

• Unzip the file.

• Go to your Xcode project’s target “General” settings. Drag MPQRCoreSDK.framework to the “Embedded Binaries” section. Make sure to select Copy items if needed and click Finish.

• Create a new Run Script Phase in your app’s target’s Build Phases and paste the following snippet in the script text field:

  bash "${BUILT_PRODUCTS_DIR}/${FRAMEWORKS_FOLDER_PATH}/MPQRCoreSDK.framework/strip-frameworks.sh"

  This step is required to work around an App Store submission bug when archiving universal binaries.

Objective-C

• Follow same instructions as Swift

Usage

Parsing

Swift

import MPQRCoreSDK

func parseQRCode(code: String) {
  do {
      // Parse qr code
      let pushData = try MPQRParser.parse(string:code)
      // Print data in string format
      print(pushData.dumpData())
  } catch let error as MPQRError{
      if let str = error.getString(){
           print("Error: \(str)")
      }else
      {
          print("Unknown error occurred \(error)")
      }
  } catch {
      print("Unknown error occurred \(error)")
  }
}

Objective-C

@import MPQRCoreSDK;

- (void)parseQRCode:(NSString *)code {
    PushPaymentData *pushPaymentData;
    NSString* (^handleError)(MPQRError *) = ^NSString* (MPQRError* error) {
        if (error.domain == MPQRErrorDomain) {
            return [NSString stringWithFormat:@"Error: %@", [error getString]];
        }
        return [NSString stringWithFormat:@"Unkown error occured %@", error];
    };

    MPQRError *error;
    pushPaymentData = [MPQRParser parse:code error:&error];

    if (error) {
        NSLog(handleError(error));
    }else
    {
        NSLog([pushPaymentData dumpData]);
    }
}

Generating

Swift

import CoreImage

func generateQRCode(from string: String) -> UIImage? {
    let data = string.data(using: String.Encoding.utf8)

    if let filter = CIFilter(name: "CIQRCodeGenerator") {
        filter.setValue(data, forKey: "inputMessage")
        // Set scale according to your device display. If the qr code is blurry then increase scale
        let transform = CGAffineTransform(scaleX: 3, y: 3)

        if let output = filter.outputImage?.transformed(by: transform) {
            return UIImage(ciImage: output)
        }
    }
    return nil
}
