Scroll View in Auto Layout

I've read a few posts that have the same problem as me. My scroll view is not behaving very well with auto layout. I uncheck auto layout and it's fine, however I have two buttons (next and previous) that need to stay at the bottom of the superview which I don't know how to without autolayout D: I have an image view in the scroll view and its not showing the whole image it ends halfway through showing the image. I have the image view set for 300 width and 500 height.

Would anyone be able to help me out with how to programmatically set "bottom space to super-view" constraints on objects? Alternatively, I'm sure there's some way to accomplish this using auto layout apple wouldn't do that to me lol.

what i've tried:

-(void)viewDidAppear:(BOOL)animated
{
  [super viewDidAppear:animated];
  [scroller setScrollEnabled:YES];
  [scroller setContentSize:CGSizeMake(320, 2000)];
}

I've also set height and width constraints and played around with sizing until I couldn't take it anymore. What it does is it just scrolls a tiny tiny bit and then that's it. I suppose programmatically setting the constraints for my buttons and unchecking autolayout is an option but there must be some way accomplish this with auto layout. Any suggestions greatly appreciated.Thanks!

    scrollViewMain.frame = CGRectMake(0, 0, 768, 815);
    [scrollViewMain setContentSize:CGSizeMake(768, 1040)];
}else {
    scrollViewMain.frame = CGRectMake(0, 0, 320, 370);

Interesting. Resolved it by selecting the bottom to super view constraint and checked the "standard" check box next to the "Constant" field and let it auto set, and it scrolled! yaaaay. I guess auto layout is your friend once you learn how to talk to it ^^
