• Implement protocol delegate IDT_NEO2Delegate::deviceDisconnected() and IDT_NEO2Delegate::device←-
Connected() to monitor connect/disconnect events and modify our connection label upon change.
Reference: Implement Optional Delegate Protocols
func setConnectionStatus(_ status: String, backgroundColor: UIColor) {
connectionStatus.text = status;
connectionStatus.backgroundColor = backgroundColor
}
func appendMessageToLog(_ message: String) {
logTextView.text = "\n" + (logTextView.text) + "\n" + (message)
logTextView.scrollRangeToVisible(NSRange(location: 0, length: 0))
}
func displayReturnError(_ operation: String, rt: RETURN_CODE) {
let message = operation+" ERROR: ID-" + String(describing: rt) + "Message: " + (
IDT_NEO2.sharedController().device_getResponseCodeString(Int32(rt.rawValue)))
appendMessageToLog(message)
}
func deviceConnected() {
setConnectionStatus("Connected", backgroundColor: UIColor.green)
appendMessageToLog("NEO2 Connected\nFramework Version:" + IDT_Device.sdk_version())
}
func deviceDisconnected() {
setConnectionStatus("Disconnected", backgroundColor: UIColor.red)
}
• Implement protocol delegate swipeMSRData:() to receive card swipe data. Reference: Implement Optional
Delegate Protocols
