UITabBarController is a handy control for building user interfaces, but it has an annoying limitation: if there are more than five tabs, a "More" button replaces the fifth tab. The user might not understand what "More" means or the fact that it hides additional controllers.
JFATabBarController is a pluggable replacement for
UITabBarController that eliminates this limitation. The user of this control can access an arbitrary number of controllers simply by swiping left on the tab bar. By default,
JFATabBarController displays an exciting animation when changing tabs.
Installation and Use
JFATabBarController, just clone the repository, double-click
JFATabBarController.xcodeproj, and run on an iPhone or iPad simulator or device.
Here are the steps to use
JFATabBarController in your app. These instructions assume familiarity with use of
JFAArrowView.hto your project. Alternatively, add
pod 'JFATabBarController'to your
Podfileand do a
- If you do not already have a
UITabBarControllerin your storyboard, add one.
- Change the class of this
JFATabBarControllerby selecting it, opening the Utilities pane, showing the Identity inspector, and changing the class to
- If you have not done so already, create a "relationship segue - view controller" from the
JFATabBarControllerto each view controller you want accessible from the tab bar.
- For each view controller accessible from the tab bar, either set the name and image of the tab-bar item or change the identifier to a system item like "Favorites" or "Bookmarks".
There are two constants of interest in
MAX_TAB_COUNT is the maximum number of tab-bar items to show at once. You are not limited to
TAB_ANIMATION_DURATION is the duration of the tab-changing animation. The larger the number, the longer the duration. Set this to 0.0 to prevent animation.
JFATabBarController has been tested on iPhone SE, iPhone X, iPhone
Because the app for which
JFATabBarController was created, Immigration, has no need for
UITabBarController’s localization, badge, or accessibility features,
JFATabBarController does not currently support them. The app may require these features at some point, and
JFATabBarController will support them then. Pull requests are welcome.
