iOS 7, table header view does not float

Question

I have a UITableView set up on my app, which runs on iOS 7. I has one section and it loads images into custom cells and it scrolls under the navigation bar

Answer 1

Change the table view's style from Grouped to Plain.

From the official documentation, regarding the Plain table view style:

A plain table view can have one or more sections, sections can have one or more rows, and each section can have its own header or footer title. (A header or footer may also have a custom view, for instance one containing an image). When the user scrolls through a section with many rows, the header of the section floats to the top of the table view and the footer of the section floats to the bottom.
