Apple watch support about qrcode

[antonioreyna]

I would like to add it to watch too.

[aschuch]

Should be possible, I'll try to add that alongside swift 2.3 and 3.0 support in the near future.

he only way to show the clock qr is sending them from iPhone to watch

[antonioreyna]

i send a rendered png of the QR from my iphone app to the watch in a current project.

I'm trying to do with WatchConnectivity but I find the error

Domain Error Code = 7014 = WCErrorDomain "Could not be delivered Payload." UserInfo = {NSLocalizedDescription = Payload Could not be delivered.}

This is the side of the watch
session.sendMessage ([ "reference" self.qr_data], replyHandler: {(response) -> Void in    if let imageQR = response [ "imageQR"] he? NSData, let boardingPass = UIImage (data: imageQR as Data) {       self.imagenPass = boardingPass       DispatchQueue.main.async (execute: {() -> Void in       self.showBoardingPass ()        })      }}, ErrorHandler: {(error) -> Void in               print (error)    })

 On the side of the phone (AppDelegate.swift)
func session (_ session: WCSession, didReceiveMessage message: [String: Any], replyHandler: @escaping ([String: Any]) -> void) {         if let reference = message [ "reference"] he? String, let boardingPass = QRCode (reference) {             replyHandler ([ "imageQR" boardingPass.PNGData as AnyObject])         }     }

I am with watchOS3 and iOS10 in previous versions these methods functioned. I don´t know if be a problem of simulator. Any help would be greatly appreciated.
A greeting.

i send the QR like this:

func createImageForWatch(_ qr_string: String) {

        if WCSession.isSupported() {
            WCSession.default().delegate = self
            WCSession.default().activate()
        } else {
            return
        }

        if var qrCodeObject = QRCode(qr_string) {
            qrCodeObject.size = CGSize(width: 135, height: 135)
            qrCodeObject.color = CIColor(color: UIColor.black)
            qrCodeObject.backgroundColor = CIColor(color: UIColor.white)

            let qrImg = qrCodeObject.image!
            let data = UIImageJPEGRepresentation(qrImg!, 1.0)

            let userInfo: [String: Any] = [
                "QR" : data!
            ]
            WCSession.default().transferUserInfo([
                "MyData" : userInfo
                ])
        }
    }

@diolce i think the problem could be that, now you need to have all the delegate methods in the session delegate.

in my case in the viewController that creates the image i have this as that is my delegate.

//MARK: WatchConnectivity Session Delegate
    func session(_ session: WCSession, activationDidCompleteWith activationState: WCSessionActivationState, error: Error?) {
        print("activationDidCompleteWith")
    }

    func sessionDidBecomeInactive(_ session: WCSession) {
        print("sessionDidBecomeInactive")
    }

    func sessionDidDeactivate(_ session: WCSession) {
        print("sessionDidDeactivate")
    }

Hey @antonioreyna
can you tell me why it is 135 instead of 136? Apple Watch 38 size is 272, not 270 so I'd like to know why it's better to use the 135 value.

Thanks

hello, in my case i added it a table row and i wanted some padding so i used that size 😃
