Objective-C - Finding a URL within a string

Question

Given a large string, what is the best way to create an array of all valid urls which are contained within the string?

This is best way to extract url link.

NSString *url_ = @"dkc://name.com:8080/123;param?id=123&pass=2#fragment";

NSURL *url = [NSURL URLWithString:url_];

NSLog(@"scheme: %@", [url scheme]);

NSLog(@"host: %@", [url host]);

NSLog(@"port: %@", [url port]);

NSLog(@"path: %@", [url path]);

NSLog(@"path components: %@", [url pathComponents]);

NSLog(@"parameterString: %@", [url parameterString]);

NSLog(@"query: %@", [url query]);

NSLog(@"fragment: %@", [url fragment]);

Output:

scheme: dkc

host: name.com

port: 8080

path: /12345

path components: ( "/", 123 ) parameterString: param

query: id=1&pass=2

fragment: fragment
