Create parameter for "Cancel" button

[davorpeic]

It would be great if we could define "Cancel" button translation from calling the plugin from our function.

thank you Davor

+1. When I press the back button of my phone and error callback fires

@LTroya your issue is simply not handling cancel correctly - unrelated to @davorpeic's request:

Check if the error callback's argument is exactly "cancelled":

error('cancelled') If user cancelled the scan (with back button etc)

@davorpeic agreed this would be a good addition. Filed for addition when I have time to do so.

In CsZbar.m:

        UIButton *cancelButton = [[[[[[[self.scanReader.view.subviews objectAtIndex:2] subviews] objectAtIndex:0] subviews] objectAtIndex:2] subviews] objectAtIndex:0];
        [cancelButton setTitle:@"Whatever you want" forState:UIControlStateNormal];

Hey all,

looks like https://github.com/tjwoon/csZBar/pull/78 has broken this fix.

I'm no good on the native side but have got things working by replacing

UIButton *cancelButton = [[[[[[[self.scanReader.view.subviews objectAtIndex:2] subviews] objectAtIndex:0] subviews] objectAtIndex:2] subviews] objectAtIndex:0];

with

UIButton *cancelButton = [[[[[[[self.scanReader.view.subviews objectAtIndex:2] subviews] objectAtIndex:0] subviews] objectAtIndex:infoButtonIndex-1] subviews] objectAtIndex:0];

Hope this helps someone
