We require a report and block user buttons creating for our ios mobile app

We have a iOS application and we need a report function built onto the article pages on our app, we want this so that any users reading any articles on our app can report any bad posts to us and the report gets submitted to us in our admin dashboard on our desktop website. Our ios app is created in objective-c. We already have iPhone app working and website so this should be easy. We also need a mechanism for users to click 'block' to any user they do not like to see anymore articles of anymore in future. In terms of design and the way the report system works we really like the one in the reddit iOS application so please download there app and look at this for reference when you report post. When you download there app look at a article and click the three small dots to bring up the report post menu.
