In my application i need to scan the bar code. for that i am using Linea pro bar code scanning device attached with my iPhone. i need to know the presence of device through code. is it possible? I am new to objective C . Help me to fix this issue.
Thank you.
Yes, it is possible.
All you have to do is this:
int lineaStatus = [[Linea sharedDevice] connstate];
Them just compare them to the different connection states like this.
if(lineaStatus == CONN_DISCONNECTED) {
//Device is connected
} else if(status == CONN_CONNECTED) {
//Device is disconnected.
}
