SFSafariViewController all the things is a tweak available since last night in Cydia for our iPhone, iPad and iPod Touches, giving us the opportunity to implement a useful function in iOS 9.
More precisely, using SFSafariViewController all the things we can implement an internal browser for certain applications that do not offer such functionality, they normally open Safari when we access a link sent through them.
According to the developer SFSafariViewController all the things, only the applications Gmail, WhatsApp, Twitter si Alien Blue it provides this functionality for us after installing the package, so don't expect it to be available in other similar titles.
iOS 9 added a new feature for developers, an in app browser that's basically an "external" Safari view. This allows apps to open a Safari window in-app, meaning your current logins and the ability to use the keychain are retained. This is helpful in apps like Gmail, where clicking a link would otherwise require a login on the page again, or for the user to open it in Safari later).
SFSafariViewController all the things is available for download from Cydia's BigBoss repo.
