Hello,

This a very nice work, but I have one question, it is possible to put a logo in the middle of the QR Code ?

Thank's in advance.

Hey Guys,

Trying to convert image to nsdata, but receive nil. Tried both PNG and JPEG.

let qrc = QRCode("sample")
let img = UIImagePNGRepresentation(qrc.image!) // img is nil 

Please advice

The created image gets streched even when using UIViewContentModeScaleAspectFit on a UIImageView.

Fixed it by adding another conversion step (CIImage -> CGImage -> UIImage).

Update: This also fixes image preview in the debugger.

To build for Swift 3.0
for the time being you need to add this to your Podfile

`pod 'QRCode', :git => "[email protected]:aschuch/QRCode.git", :branch => "swift3.0"`

Hi,

Below code will be crashed on Xcode8

guard let cgImage = CIContext(options: nil).createCGImage(self, fromRect: self.extent) else { return nil }

'NSInvalidArgumentException', reason: '-[CIContext initWithOptions:]: unrecognized selector

Is it possible to add extension for apple watch ?

swift package init

Please add Package.swift

Can you push latest Pod to CocoaPods registry

Is there a specific reason why the initialisers for string and NSURL both encode the input as latin1 instead of UTF-8?

public init?(_ string: String) {
        if let data = string.dataUsingEncoding(NSISOLatin1StringEncoding) {
            self.data = data
        } else {
            return nil
        }
    }

public init?(_ url: NSURL) {
    if let data = url.absoluteString.dataUsingEncoding(NSISOLatin1StringEncoding) {
        self.data = data
    } else {
        return nil
    }
}

Dear Alexander, how are you?

On swift 4 build IOS 11 I'm facing a warning that is relatively easy to solve:

Class: CIColorExtension.swift
Line 32:

if scanner.scanHexInt64(&hexValue) {
let length = rgba.characters.count

Warning Message: 'characters' is deprecated: Please use String or Substring directly

Thanks

Crash when using CIContext(options:) in CIImageExtensions.swift line 21. Seems to be an issue of Xcode 8 which is having issues translating the Swift 3 options: notation into contextWithOptions: (instead of initWithOptions). Writing a second helper extension in Obj-C would be a workaround.

I placed the high error correction in and the code still appears blurry.

    var qrImage = UIImageView(frame: CGRectMake((lpScroll.frame.size.width - qrWidth) / 2, ish, qrWidth, qrWidth))
    let url = NSURL(string: url4Sharing)
    var qrCode = QRCode(url!)
    qrCode?.errorCorrection = QRCode.ErrorCorrection.High
    qrCode?.color = CIColor(color: UIColor.cloudsColor())
    qrCode?.backgroundColor = CIColor(color: darkColor)
    qrCode?.size = CGSize(width: qrWidth * 2, height: qrWidth * 2)
    qrImage.image = qrCode?.image
    lpScroll.addSubview(qrImage)

I received this error when i try to install this library with cathage.

In cartfile:
github "aschuch/QRCode"

Error:
*** Building scheme "QRCode" in Example.xcodeproj
** BUILD FAILED **

The following build commands failed:
CompileSwift normal x86_64 /project-path/Carthage/Checkouts/QRCode/QRCode/CIColorExtension.swift
CompileSwiftSources normal x86_64 com.apple.xcode.tools.swift.compiler
(2 failures)

it would be great to leverage this in tvOS

Can you update the pod on CocoaPods to 1.0 please? :)

any plan to update to swift 4?

i think using extension to invoke have a better experience. like:
stringA.QRImage()
this method could have some default parameters,like size or something else.

if you agree with this , I can spend some time work on it,create a pull request

Hi,

What is the maximum capacity that can be encoded for an ASCII encoded string?

Thanks,
:panos

UIImage(data: QRCode("WILLLiiii")!.data)

ios9

The latest version available on cocoapods is 0.5. Maybe you forgot to update the new version on cocoapods ?

Hi,

What is the error correction level used for the generated qr codes?

Is there a way to specify it?

Thanks,
:panos

i guess you need to app a key to info.plist for Privacy - Media Library Usage Description
app Binary was invalid till i add to my info.plist the Error was missing this Key "NSPhotoLibraryUsageDescription"

please put a hint in readme file as it required from iOS 10

branch: Swift 2.2
xcode 7.3.x

Steps to repro:

1. clone
2. switch to branch 2.2
3. open example project in xcode and build
