Disconnecting Readers

In disconnected readers it is likely that the appropriate reader events should be subscribed to. It is best practice to assert that a reader is connected before proceeding so users aren't confused by erroneous messages.

With an audio jack reader:

if ( CardReaderController.isCardReaderConnected() && CardReaderController.getConnectedReader().getConnectionMethod() == CardReader.ConnectionMethod.AUDIO )
{
	// instruct user to physically disconnect device
}
else
{
	// indicate no audio device detected
}

- (IBAction)disconnectReader:(id)sender {
    [[ANPCardReaderController sharedController] subscribeOnCardReaderError:^(ANPMeaningfulError * _Nullable error) {
        NSLog(@"OnCardReaderError --> %@", error);
        
        [self appendText:[NSString stringWithFormat:@"\n\nOnCardReaderError %@", error.message]];
    }];
    
    [[ANPCardReaderController sharedController] subscribeOnCardReaderDisConnected:^{
        NSLog(@"OnCardReaderDisConnected");
        
        [self appendText:@"\n\n OnCardReaderDisConnected"];
    }];
    
    [[ANPCardReaderController sharedController] disconnectReader];
}

With a bluetooth reader:

if ( CardReaderController.isCardReaderConnected() && cardReader.getConnectionMethod() == CardReader.ConnectionMethod.BLUETOOTH)
{
	// indicate bluetooth disconnection in progress
	cardReaderController.disconnectReader();
}
else
{
	// indicate no bluetooth reader connected
}

- (IBAction)disconnectReader:(id)sender {
    [[ANPCardReaderController sharedController] subscribeOnCardReaderError:^(ANPMeaningfulError * _Nullable error) {
        NSLog(@"OnCardReaderError --> %@", error);
        
        [self appendText:[NSString stringWithFormat:@"\n\nOnCardReaderError %@", error.message]];
    }];
    
    [[ANPCardReaderController sharedController] subscribeOnCardReaderDisConnected:^{
        NSLog(@"OnCardReaderDisConnected");
        
        [self appendText:@"\n\n OnCardReaderDisConnected"];
    }];
    
    [[ANPCardReaderController sharedController] disconnectReader];
}
