ZBar SDK iOS: How can I change cancel button text?

Question

I'm trying to use ZBar SDK and It works perfectly My only question is how can I change the cancel button text to be multilanguage

This is the code I'm using

ZBarReaderViewController *codeReader = [ZBarReaderViewController new];
codeReader.readerDelegate=self;
codeReader.supportedOrientationsMask = ZBarOrientationMaskAll;


ZBarImageScanner *scanner = codeReader.scanner;
[scanner setSymbology: ZBAR_I25 config: ZBAR_CFG_ENABLE to: 0];

[self presentViewController:codeReader animated:YES completion:nil];
