I am using a UITabBarController
but I only have 2 tabs. Instead of using icons I just want to use text. I created a bar item title but the text is very small and I'm having a hard time modifying it. How can I make a bar item just text that fits the section reasonably?
I've tried to change the font size programmatically but I'm fairly new to swift and am struggling.
import UIKit
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
UITabBar.appearance().tintColor = .white
UITabBarItem.appearance().setTitleTextAttributes([NSAttributedString.Key.foregroundColor: UIColor.white], for: .selected)
UITabBarItem.appearance().setTitleTextAttributes([NSAttributedString.Key.foregroundColor: UIColor.lightGray], for: .normal)
return true
}
}
The UITextAttributeFont was deprecated in iOS 7. You should use the NS variant instead:
import UIKit
let appearance = UITabBarItem.appearance()
let attributes = [NSAttributedStringKey.font:UIFont(name: "Your font style", size: 20)]
appearance.setTitleTextAttributes(attributes as [NSAttributedStringKey : Any], for: .normal)
For each of the UIViewController
in UITabBarController
, call setTitleTextAttributes(_:for:)
on controller's tabBarItem
in viewDidLoad()
, ie
class VC1: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
self.tabBarItem.setTitleTextAttributes([.font: UIFont.systemFont(ofSize: 20.0, weight: .regular)], for: .normal)
}
}
class VC2: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
self.tabBarItem.setTitleTextAttributes([.font: UIFont.systemFont(ofSize: 20.0, weight: .regular)], for: .normal)
}
}
Edit:
Since you've created the controllers
of tabBarController
in the storyboard
, here is how you can get that working.
Subclass UITabBarController
and set the titleTextAttributes
of its viewControllers``
tabBarItem in
viewDidLoad()`, ie
class TabBarController: UITabBarController {
override func viewDidLoad() {
super.viewDidLoad()
self.viewControllers?.forEach({
$0.tabBarItem.setTitleTextAttributes([.font: UIFont.systemFont(ofSize: 20.0, weight: .regular)], for: .normal)
})
}
}
Now set TabBarController
as class
of UITabBarController
in storyboard
.
I hope this will resolve your issue.
UITabBarItem.appearance()。setTitleTextAttributes([NSAttributedString.Key.font:UIFont(name:“ FontName”,size:10)!],用于:.normal)UITabBarItem.appearance()。setTitleTextAttributes([NSAttributedString.Key.font: UIFont(name:“ FontName”,size:10)!],代表:.selected)
