dyqrcodecoder is a lightweight Objective-C library for generating QR codes. It provides a simple and easy-to-use interface for creating QR codes and customizing their appearance. This library is built on top of Apple’s Core Image framework, making it efficient and reliable.
- Generate QR codes with text, URLs, or other data.
- Customize QR code size, error correction level, and encoding mode.
- Add logos or images to QR codes.
- Change QR code color, background color, and transparency.
- Generate high-resolution QR codes for print usage.
- Support for iOS devices running iOS 9 and above.
You can install dyqrcodecoder using CocoaPods. Add the following line to your Podfile:
pod 'dyqrcodecoder'
To generate a basic QR code with dyqrcodecoder, follow these steps:
#import <dyqrcodecoder/dyqrcodecoder.h>
QRCoder *qrcoder = [[QRCoder alloc] init];
UIImage *qrCodeImage = [qrcoder generateQRCodeWithString:@"Your Data" size:200];
UIImageView *qrCodeImageView = [[UIImageView alloc] initWithImage:qrCodeImage];
[self.view addSubview:qrCodeImageView];
You can customize the appearance of the QR code using various properties of the QRCoder class. For example:
qrcoder.errorCorrectionLevel = QRCoderErrorCorrectionLevelHigh;
qrcoder.foregroundColor = [UIColor redColor];
qrcoder.backgroundColor = [UIColor whiteColor];
Refer to the library’s documentation for a full list of available properties and customization options.
Here’s an example of generating and customizing a QR code:
QRCoder *qrcoder = [[QRCoder alloc] init];
qrcoder.size = 300;
qrcoder.errorCorrectionLevel = QRCoderErrorCorrectionLevelMedium;
qrcoder.foregroundColor = [UIColor blackColor];
qrcoder.backgroundColor = [UIColor whiteColor];
UIImage *qrCodeImage = [qrcoder generateQRCodeWithString:@"https://example.com" size:qrcoder.size];
UIImageView *qrCodeImageView = [[UIImageView alloc] initWithImage:qrCodeImage];
qrCodeImageView.contentMode = UIViewContentModeScaleAspectFit;
[self.view addSubview:qrCodeImageView];
