The problem is that it looks like it is using the title bar of the navigation bar, which is actually located where you want your segmented control to work. Instead, you need to add a tooltip to the navigation bar to increase the height of the panel, and add tooltip text above the panel's content area.
This can be done exclusively in the Builder interface, as shown in the screenshot below, or programmatically using the following code:
[self.navigationController.navigationItem setPrompt:@"some prompt text"];
