我正在使用UITabBarController
,但是我只有2个标签。我只想使用文本,而不是使用图标。我创建了一个酒吧项目标题,但是文本很小,并且很难修改它。我怎样才能使一个条形项目只是适合该部分的文本?
我试图以编程方式更改字体大小,但我还很新,很快就遇到了麻烦。
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
}
}

UITextAttributeFont在iOS 7中已弃用。您应该改用NS变体:
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)

对于UIViewController
中的每个UITabBarController
,请调用setTitleTextAttributes(_:for:)
中控制器的tabBarItem
上的viewDidLoad()
,即
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)
}
}
编辑:
自从您在controllers
中创建了tabBarController
的{{1}}以来,这里就是如何使之工作的方法。
子类storyboard
并设置其UITabBarController
tabBarItem titleTextAttributes
viewDidLoad()`的viewControllers``
,即
in
现在将class TabBarController: UITabBarController {
override func viewDidLoad() {
super.viewDidLoad()
self.viewControllers?.forEach({
$0.tabBarItem.setTitleTextAttributes([.font: UIFont.systemFont(ofSize: 20.0, weight: .regular)], for: .normal)
})
}
}
中TabBarController
的{{1}}设置为class
。
我希望这能解决您的问题。

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)!],用于:.selected)
