A QRCode generator written in Swift.
Create a new QRCode representing a URL
, a string or arbitrary data.
The following examples all result in the same QRCode image.
// URL
let url = URL(string: "https://schuch.me")!
let qrCode = QRCode(url)
qrCode?.image
// String
let qrCode = QRCode("https://schuch.me")
qrCode?.image
// NSData
let data = "https://schuch.me".data(using: .isoLatin1)!
let qrCode = QRCode(data)
qrCode.image
Make sure to declare your
QRCode
instance as a variable in order make use of the following features.
Adjust Output Size
Change the output size of the QRCode output image via the size
property.
qrCode.size = CGSize(width: 300, height: 300)
qrCode.image // UIImage (300x300)
Color
Modify the colors of the QRCode output image via color
and backgroundColor
properties.
qrCode.color = CIColor(rgba: "16a085")
qrCode.backgroundColor = CIColor(rgba: "000")
qrCode.image // UIImage (green QRCode color and black background)
Note: The above examples make use of the
CIColor
extension that ships with this project to create colors based on HEX strings.
For convenience, a UIImageView
extension is provided to directly initialize an image view with an instance of QRCode
.
let imageView = UIImageView(qrCode: qrCode)
In case you love emoji as much as I do, make sure to create your QRCode
instance using the 🔳 typealias.
let qrCode = 🔳("https://example.com")
