`-(BOOL)searchForVideoInBOFUNKHTML:(NSString*)htmlString;
{
    NSString *strHTML=[NSString stringWithFormat:@"%@",htmlString];       
    NSString *newString; 

    if ([htmlString rangeOfString:@"id=\"vidplaya\""].location == NSNotFound) 
    {
        return  false;
    }   
    else
    {
        htmlString = [strHTML substringFromIndex:[htmlString rangeOfString:@"id=\"vidplaya\""].location];

        htmlString=  [htmlString stringByReplacingOccurrencesOfString:[htmlString substringFromIndex:100]
                                                        withString:@""];



            newString =[htmlString stringByReplacingOccurrencesOfString:[htmlString substringFromIndex:[htmlString rangeOfString:@"quality"].location] withString:@""];
        NSLog(@"%@",newString);

            newString = [[[newString substringFromIndex:[newString rangeOfString:@"/"].location] substringFromIndex:3] stringByReplacingOccurrencesOfString:@"\"" withString:@""];
         NSLog(@"%@",newString);

            newString = [newString stringByReplacingOccurrencesOfString:@" " withString:@""];
         NSLog(@"%@",newString);


            embededURL = [[NSString alloc] initWithFormat:@"http://media.bofunk.com/media/flvs/%@.flv",newString]; 

        NSLog(@"%@",embededURL);
            return true;

    }
    return  false;

}

`But is not working for sites like dailymotion.com.Is it an issue related to any kind of encryption on these sites?

回答1:

Dailymotion provides an API for iOS. So you can use it. But don't expect it to work with other services. You will have to implement them all one by one. Some of them might be impossible to use with external software.
