Best thing about NSURLConnection is its asynchronous behaviour so that you dont have to wait until the url is loaded.

  • The Connection

    An NSURLConnection object provides support to perform the loading of a URL request.

  • The Request

    NSURLRequest objects represent a URL load request in a manner independent of protocol and URL scheme.

    E.g. requestWithURL:

    Creates and returns a URL request for a specified URL with default cache policy and timeout value.

    + (id)requestWithURL:(NSURL *)theURL

  • The URL

    The NSURL class provides a way to manipulate URLs and the resources they reference. NSURL objects understand URLs as specified in RFCs 1808, 1738, and 2732. ...

    To get the contents of a URL, NSString provides stringWithContentsOfURL: and NSData provides dataWithContentsOfURL:.
