Question 1

How do I change the colors in FoldingTabBar?

Accepted Answer

You can customize colors by setting properties like backgroundColor, tabBarColor, and dotColor on the tabBarView. The README provides Objective-C and Swift code snippets for this in the Tips for customization section.

Question 2

FoldingTabBar vs standard UITabBar: which should I use?

Accepted Answer

FoldingTabBar is ideal for apps wanting animated, interactive navigation with extra buttons, but it deviates from standard HIG. Use standard UITabBar for simplicity, accessibility, and compliance with iOS design patterns.

Question 3

How to add extra action buttons to a tab?

Accepted Answer

Define leftItemImage and rightItemImage when creating a YALTabBarItem. Then, implement the delegate methods tabBarDidSelectExtraLeftItem or tabBarDidSelectExtraRightItem in your view controller to handle button taps, as shown in the Usage section.

Question 4

Does FoldingTabBar support SwiftUI?

Accepted Answer

No, FoldingTabBar is built on UIKit and optimized for Storyboard integration. For SwiftUI projects, you would need to wrap it in a UIViewRepresentable or seek alternative SwiftUI-based tab bar components.

Question 5

How to handle tab selection events in FoldingTabBar?

Accepted Answer

Implement the tabBar:didSelectItemAtIndex: delegate method from YALTabBarDelegate. The README includes Objective-C and Swift examples for this callback, allowing custom actions on tab switches.

Question 6

Can I use FoldingTabBar without Interface Builder?

Accepted Answer

Yes, you can instantiate YALFoldingTabBarController programmatically, but the README focuses on Storyboard setup. Manual initialization requires more code, as seen in the AppDelegate examples for configuring bar items.
