I know its quite a late response to this question and I agree that, Murat's answer is absolutely correct. Simply add a check as follows:

NSURL *urlApp = [NSURL URLWithString: [NSString stringWithFormat:@"%@", @"twitter:///user?screen_name=PAGE]];

if ([[UIApplication sharedApplication] canOpenURL:urlApp]){
        [[UIApplication sharedApplication] openURL:urlApp];
    }

I hope this helps someone. Cheers!! :)
