目前在Objective-C中,我使用Zbar(
http://zbar.sourceforge.net/)生成&阅读QR码.现在,我想继续开发Swift开发,是否有关于在Swift中生成和读取QR代码的“如何”或库？
这是我写的用于在swift中生成QRcode的代码.
//MARK:- generate QR code
func generateQRImage(stringQR:NSString,withSizeRate rate:CGFloat) -> UIImage
{
var filter:CIFilter = CIFilter(name:"CIQRCodeGenerator")
filter.setDefaults()
var data:NSData = stringQR.dataUsingEncoding(NSUTF8StringEncoding)!
filter.setValue(data,forKey: "inputMessage")
var outputImg:CIImage = filter.outputImage
var context:CIContext = CIContext(options: nil)
var cgimg:CGImageRef = context.createCGImage(outputImg,fromRect: outputImg.extent())
var img:UIImage = UIImage(CGImage: cgimg,scale: 1.0,orientation: UIImageOrientation.Up)!
var width = img.size.width * rate
var height = img.size.height * rate
UIGraphicsBeginImageContext(CGSizeMake(width,height))
var cgContxt:CGContextRef = UIGraphicsGetCurrentContext()
CGContextSetInterpolationQuality(cgContxt,kCGInterpolationNone)
img.drawInRect(CGRectMake(0,width,height))
img = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
return img
}
