Take a look at the -openURL  method on UIApplication  It should allow you to pass an NSURL instance to the system  which will determine what app to open it in and launch that application   Keep in mind you ll probably want to check -canOpenURL  first  just in case the URL can t be handled by apps currently installed on the system - though this is likely not a problem for plain http    links

openURL    was deprecated in iOS 10 0  instead you should use the following instance method on UIApplication  open  options completionHandler    Example using Swift This will open  https   apple com  in Safari   if let url   URL string   https   apple com         if UIApplication shared canOpenURL url            UIApplication shared open url  options       completionHandler  nil            https   developer apple com reference uikit uiapplication 1648685-open

Swift Syntax   UIApplication sharedApplication   openURL NSURL string  http   www reddit com        New Swift Syntax for iOS 9 3 and earlier  As of some new version of Swift  possibly swift 2    UIApplication sharedApplication   is now UIApplication shared  making better use of computed properties I m guessing   Additionally URL is no longer implicitly convertible to NSURL  must be explicitly converted with as   UIApplication sharedApplication openURL NSURL string  http   www reddit com    as  URL    New Swift Syntax as of iOS 10 0  The openURL method has been deprecated and replaced with a more versatile method which takes an options object and an asynchronous completion handler as of iOS 10 0  UIApplication shared open NSURL string  http   www reddit com     as URL
