title: iOS - Add "objects" to existing app (jailbroken)
body: <p>How do you add "objects" to an existing app ?</p>
  
  <p>For example, the <a href="https://web.archive.org/web/20160724061611/http://modmyi.com:80/content/8131-easily-refresh-pages-google-chrome-easyrefresh-chrome.html" rel="nofollow noreferrer">EasyRefresh for Chrome</a> tweak, enables a new button inside the iOS Chrome app, as do many other tweaks.</p>
  
  <p>How may i add a simple <code>UIButton</code> to, for example, the Twitter app ?</p>
  
  <p>Is there any <a href="https://github.com/" rel="nofollow noreferrer">GitHub</a> projects that might help me to understand how it's done ?</p>
