• Implement protocol delegate emvTransactionData:() to report EMV transaction results
- (void) emvTransactionData:(IDTEMVData
NSLog(@"EMV_RESULT_CODE_V2_response =
[self appendMessageToResults:[NSString
if (emvData == nil) {
[self appendMessageToResults:[NSString
EMV_RESULT_CODE_V2_response =
return;
}
if (emvData.resultCodeV2 == EMV_RESULT_CODE_V2_GO_ONLINE) {
[self appendMessageToResults:@"ONLINE
}
if (emvData.resultCodeV2 == EMV_RESULT_CODE_V2_APPROVED || emvData.resultCodeV2 ==
EMV_RESULT_CODE_V2_APPROVED_OFFLINE ) {
[self appendMessageToResults:@"APPROVED"];
}
if (emvData.resultCodeV2 == EMV_RESULT_CODE_V2_MSR_SUCCESS) {
[self appendMessageToResults:@"MSR Data
}
if (emvData.cardType == 0) {
[self appendMessageToResults:@"CONTACT"];
}
if (emvData.cardType == 1) {
[self appendMessageToResults:@"CONTACTLESS"];
}
if (emvData.unencryptedTags != nil)
Unencrytped Tags:
if (emvData.encryptedTags != nil)
Tags: %@", emvData.encryptedTags.description]];
if (emvData.maskedTags != nil)
%@", emvData.maskedTags.description]];
}
• Implement protocol delegate lcdDisplay:() to receive LCD messages, and automatically select 1st menu
item/language when presented with choices. Normal operation would require a choice be made by card
holder.
- (void) lcdDisplay:(int)mode
NSMutableString * str = [NSMutableString new];
if (lines != nil) {
for (NSString * s in lines) {
[str appendString:s];
[str appendString:@"
}
}
switch (mode) {
case 0x10:
//clear screen
lcdTextView.text = @"";
break;
case 0x03:
lcdTextView.text = str;
break;
case 0x01:
case 0x02:
case 0x08:{
[[IDT_NEO2
}
break;
default:
break;
}
}
• Implement the button press methods
-(IBAction) getFirmware:(id)sender{
NSString * result;
logTextView.text = @"";
RETURN_CODE rt =
IDTech iOS SDK Guide for NEO2 #80152802-001
* )emvData errorCode:(int)error{
%2X",error);
stringWithFormat:@"EMV_RESULT_CODE_V2_response =
0x%2X",error]];
[self

[self appendMessageToResults:[NSString
[self appendMessageToResults:[NSString
lines:(NSArray * )lines{
n"];
sharedController] emv_callbackResponseLCD:mode
[[IDT_NEO2 sharedController]

REQUEST"];
Captured"];
appendMessageToResults:[NSString
device_getFirmwareVersion:&result];
%2X",error]];
