我在 swift5 中使用 NavigationBar。NavigationBar 背景顏色顯示黑色.. 這是我的圖片
這是我的代碼：
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
self.navigationController?.navigationBar.tintColor = UIColor.red
self.navigationController?.navigationBar.barTintColor = UIColor.green
self.navigationController?.navigationBar.barTintColor = .red
self.navigationItem.title = "ABC title"
self.navigationController!.navigationBar.titleTextAttributes = [NSAttributedString.Key.foregroundColor : UIColor.white]
self.navigationController?.navigationBar.isTranslucent = false
}
}
我的代碼有什么問題？請幫我
uj5u.com熱心網友回復：
這就是為什么在 iOS 15 NavigationBars 中使用 scrollEdgeAppearance，如果你想使用舊的外觀，你必須像這樣宣告它：
override func viewDidLoad() {
super.viewDidLoad()
let appearance = UINavigationBarAppearance()
appearance.configureWithOpaqueBackground()
appearance.backgroundColor = .red
appearance.titleTextAttributes = [NSAttributedString.Key.foregroundColor : UIColor.white]
self.navigationController?.navigationBar.standardAppearance = appearance;
self.navigationController?.navigationBar.scrollEdgeAppearance = self.navigationController?.navigationBar.standardAppearance
self.navigationItem.title = "ABC title"
}
這就是結果：
