Hi, thanks for the report. Unfortunately I am in between exams and could not test it out. But here's what i suggest:

        // ADD THIS IF CONDITION
        if !loaded {
            // Insert empty tab item at center index. In this case we have 5 tabs.
            self.insertEmptyTabItem("", atIndex: 2)

            // Raise the center button with image
            let img = UIImage(named: "icon_camera")
            self.addRaisedButton(img, highlightImage: nil)
        }

If it works feel free to submit a pull request, or i'll check this out later.
