I am building a news app for iPhones.

The app has five main sections which are news, videos, articles ( different from new ), settings and favorites. All these sections are tabbed at the bottom using Tab Bar Controller. Example as below:

enter image description here

But for news and videos, there are categories which users can select such as "Latest", "Top News" etc. How do I view these categories while maintaining a clean look? Android has a slider tab element which works, but on iOS, I can't seem to find these second tier navigation options.

Any ideas?

Use Bottom Tabs to show your main functionalities. In your example News on Tab and Create Segmented Tabs inside a tab and add latest there. Check image

  • The categories is a long list. It has at least six items. Won't it look a little crowded? – Eshwaren Manoharen Jan 3 '17 at 6:50

According to iOS Human Interface Guidelines (emphasis mine):

Each additional tab reduces the tappable area for selecting a tab and increases the complexity of your app, making it harder to locate information. Although a More tab can display extra tabs, this requires additional taps and is a poor use of space. Include essential tabs only, and use the minimum tabs necessary for your information hierarchy. Too few tabs can be a problem too, as it can make your interface feel disconnected. In general, use between three and five tabs on iPhone. A few more are acceptable on iPad.


In Material design the Tab bar can be scrollable:


However in a Bottom Navigation, like the one you show in the image, Material design doesn't recommend making it scrollable:

Don't.

Avoid scrollable content in the bottom navigation bar.

  • Thanks for the answer. But my problem remains. I still have a vague idea on how to display the categories. There are about at least 6 categories each, which means I can't use the tabs. – Eshwaren Manoharen Jan 5 '17 at 3:59
