Get the domain part of an URL string?

Question

I have an NSString with an URL, in this way:

http://someurl.com/something

How would I get someurl.com only? I\'ve already trie

Answer 1

Use

[[NSURL URLWithString:@"http://someurl.com/something"] host]

Answer 2

Swift 4

And if you are using Custom url schemes say for deeplinking, for eg:

myapp:homescreen

(and don't have the "forward slashes with host name" (//www.bbc)), one solution that worked for me to extract "homescreen" is by using the index method below and then pattern matching to scrape everything after ":"

let index = absoluteString.index(absoluteString.startIndex, offsetBy: 5)
String(absoluteString[index...])

url.host or absoluteURL.host is nil in this scenario

Answer 3

Swift 4.2

I wrote extension for URL to take SLD. Seems, there is n

extension URL {
    /// second-level domain [SLD]
    ///
    /// i.e. `msk.ru, spb.ru`
    var SLD: String? {
        return host?.components(separatedBy: ".").suffix(2).joined(separator: ".")
    }
}

Answer 4

You should look at the host() method of the NSURL class.

Answer 5

Objective-C

NSString* urlString = @"http://someurl.com/something";
NSURL* url = [NSURL URLWithString:urlString];
NSString* domain = [url host];

Swift 2

var urlString = "http://someurl.com/something"
var url = NSURL(string: urlString)
var domain = url?.host

Swift 3+

var urlString = "http://someurl.com/something"
var url = URL(string: urlString)
var domain = url?.host
