Hi,

I test my commit in Simplified Chinese and English, it works. Other language I've not tested. But I do find a issue with this commit, maybe it also exist in the original version.

if I use blow UIAlert code:

    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:NSLocalizedString(@"警告", @"警告") message:nil delegate:self cancelButtonTitle:NSLocalizedString(@"确定", @"确定") otherButtonTitles:nil];

It can't grep out NSLocalizedString from within a line, it generate unwanted result.
So, I need to change it to:

    NSString *title = NSLocalizedString(@"警告", @"警告");
    NSString *ok = NSLocalizedString(@"确定", @"确定");
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title message:nil delegate:self cancelButtonTitle:ok otherButtonTitles:nil];

I'm not familiar with regular expression. I've learnt serval hours on the net and try to make this commit. I think you'd better do some more test. Anyway, thanks for your wonderful tutorial, it's really helpful.
