iOS: parse a URL into segments

Question

What\'s an efficient way to take an NSURL object such as the following:

foo://name/12345 

and break it up into one string and one unsigned

Answer 1

Actually there is a better way to parse NSURL. Use NSURLComponents. Here is a simle example:

Swift:

extension URL {
    var params: [String: String]? {
        if let urlComponents = URLComponents(url: self, resolvingAgainstBaseURL: true) {
            if let queryItems = urlComponents.queryItems {
                var params = [String: String]()
                queryItems.forEach{
                    params[$0.name] = $0.value
                }
                return params
            }
        }
        return nil
    }
}

Objective-C:

NSURLComponents *components = [NSURLComponents componentsWithURL:url resolvingAgainstBaseURL:NO];
    NSArray *queryItems = [components queryItems];

    NSMutableDictionary *dict = [NSMutableDictionary new];

    for (NSURLQueryItem *item in queryItems)
    {
        [dict setObject:[item value] forKey:[item name]];
    }
