Authorization failed Error Domain=LIALinkedInERROR Code=2

[Arthraim]

After click "Sign in" on login page (the webview), I got this error, it effects all our app users. The example project in your repo doesn't work either.

for anyone else who got the same problem, i found it's Linkedin append an anchor to redirect_url. And - (NSString *)extractGetParameter: (NSString *) parameterName fromURLString:(NSString *)urlString made mistake.

fix is quite straight forward as well

- (NSString *)extractGetParameter: (NSString *) parameterName fromURLString:(NSString *)urlString {
    NSMutableDictionary *mdQueryStrings = [[NSMutableDictionary alloc] init];
    urlString = [[urlString componentsSeparatedByString:@"#"] objectAtIndex:0];
    urlString = [[urlString componentsSeparatedByString:@"?"] objectAtIndex:1];
    for (NSString *qs in [urlString componentsSeparatedByString:@"&"]) {
        [mdQueryStrings setValue:[[[[qs componentsSeparatedByString:@"="] objectAtIndex:1]
                stringByReplacingOccurrencesOfString:@"+" withString:@" "]
                stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding]
                          forKey:[[qs componentsSeparatedByString:@"="] objectAtIndex:0]];
    }
    return [mdQueryStrings objectForKey:parameterName];
}

Your above method is not available for alter. Please suggest any other possible solution to fix it.
