By default table view controllers will pad the content down under the nav bar so you could scroll the content under it and see it, in a blurred state, underneath the navbar/toolbar.

Looks like you're positioning it at 44 (maybe 64)px to move it out from under the nav bar, but it already compensates for this so you get a big gap.

Go to the storyboard/xib in IB and untick the show content under nav bar stuff.
