CarbonKit框架下Menu Tabs等宽适配问题求助

Hey there! Let's get those CarbonKit tabs sorted so your Hello World and Tab labels take up the full width of your view controller (split evenly between them). Here's how to do it:

Key Solution: Force Equal Width Tabs #

CarbonKit has a built-in method to make all tab items share the tab bar's width equally. Add this when setting up your tab navigation:

carbonTabSwipeNavigation.setTabBarItemsEqualWidth(true)

Full Modified Code Example #

Here's how to integrate this into your existing ViewController code, with all necessary setup included:

import UIKit
import CarbonKit

class ViewController: UIViewController, CarbonTabSwipeNavigationDelegate {
    
    var carbonTabSwipeNavigation: CarbonTabSwipeNavigation!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // Define your tab titles
        let tabTitles = ["Hello World", "Tab"]
        
        // Initialize the tab navigation
        carbonTabSwipeNavigation = CarbonTabSwipeNavigation(items: tabTitles, delegate: self)
        
        // Make tabs split the full width equally
        carbonTabSwipeNavigation.setTabBarItemsEqualWidth(true)
        
        // Attach the tab bar to your view controller
        carbonTabSwipeNavigation.insert(intoRootViewController: self)
        
        // Optional: Customize tab appearance (adjust as needed)
        carbonTabSwipeNavigation.toolbar.isTranslucent = false
        carbonTabSwipeNavigation.setNormalColor(.darkGray, font: UIFont.systemFont(ofSize: 16))
        carbonTabSwipeNavigation.setSelectedColor(.blue, font: UIFont.boldSystemFont(ofSize: 16))
    }
    
    // MARK: - CarbonTabSwipeNavigationDelegate
    func carbonTabSwipeNavigation(_ carbonTabSwipeNavigation: CarbonTabSwipeNavigation, viewControllerAt index: UInt) -> UIViewController {
        // Return the view controller for each tab (customize these to your needs)
        let viewController = UIViewController()
        viewController.view.backgroundColor = index == 0 ? .lightGray : .white
        return viewController
    }
    
    func generateImage(for view: UIView) -> UIImage? {
        defer { UIGraphicsEndImageContext() }
        UIGraphicsBeginImageContextWithOptions(view.bounds.size, false, UIScreen.main.scale)
        view.drawHierarchy(in: view.bounds, afterScreenUpdates: true)
        return UIGraphicsGetImageFromCurrentImageContext()
    }
}

Fallback: Manual Width Calculation #

If for some reason the setTabBarItemsEqualWidth method doesn't work with your CarbonKit version, you can manually calculate and set the width for each tab:

// Calculate width per tab (full view width divided by number of tabs)
let tabWidth = view.bounds.width / CGFloat(tabTitles.count)

// Apply the width to each tab
carbonTabSwipeNavigation.setTabWidth(tabWidth, forTabAtIndex: 0)
carbonTabSwipeNavigation.setTabWidth(tabWidth, forTabAtIndex: 1)

Either approach will make your two tabs stretch to fill the entire width of your view controller, exactly what you're looking for!
