Show a button after a time
<p>Hi sorry I'm really new to this and I need help.
I'm trying to get a button to appear after say 8 secs.
I want the app to open on a title screen then after 8 secs show a enter button to move on. 
I've set up the screens and everything with the button already there but that's not what I want.
Can someone please help?? I'm using Objective C in Xcode 7.2 and for iPhone ( remember I'm really new lol).
Thanks </p>
