iOS8 how to turn a arbitrary string into a web search, like Google Chrome browser?

When working with Google Chrome browser, I can type in a fully formed address or a sequence of words and have the browser properly format it. For example:

cnn.com -> goes to website, adds http://
cnn -> does search for cnn
//etc

Below is my method implementation to turn an arbitrary string into a web browser search.

Is there a comprehensive open source alternative to properly translating string into a web view address?

-(NSString*)cleanFormatLink:(NSString*)link
{
    //remove leading or trailing whitespace
    NSString* returnString = [link stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];;

    //check if it has spaces - do google search instead
    BOOL hasSpaces = ([returnString rangeOfString:@" "].location!= NSNotFound);
    if(hasSpaces)
    {
//        http://ift.tt/1laD9bU

        returnString = CFBridgingRelease(CFURLCreateStringByAddingPercentEscapes(NULL,
                                                                                            (__bridge CFStringRef)returnString,
                                                                                            NULL,
                                                                                            CFSTR("!*'();:@&=+$,/?%#[]\" "),
                                                                                            kCFStringEncodingUTF8));
       returnString = [@"http://ift.tt/vgrAeu" stringByAppendingString:returnString];

    }else if(([returnString rangeOfString:@"."].location!= NSNotFound))
    {
        //found a dot - most likely an address

        if(
         [[link lowercaseString] hasPrefix:@"http://"] == NO ||
         [[link lowercaseString] hasPrefix:@"https://"] == NO
         )
        {
            //fixes google.com into http://google.com
            returnString = [@"http://" stringByAppendingString:returnString];
        }

    }
    return returnString;
}
