我正在使用 Swift 5 并尝试在执行弹出操作时更改导航栏颜色的颜色。我使用了下面编写的代码，但它对我不起作用
func changeRootToLogin()
{
guard let rootVC = UIStoryboard.init(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "OnboardingViewController") as? OnboardingViewController else {
return
}
let navigationController = UINavigationController(rootViewController: rootVC)
self.navigationController?.navigationBar.backgroundColor = #colorLiteral(red: 0.2933186293, green: 0.8084665537, blue: 0.8478894234, alpha: 1)
self.navigationController?.navigationBar.isHidden = false
UIApplication.shared.windows.first?.rootViewController = navigationController
UIApplication.shared.windows.first?.makeKeyAndVisible()
}
最佳答案
使用这个
self.navigationController?.navigationBar.barTintColor = #colorLiteral(red:
0.2933186293, green: 0.8084665537, blue: 0.8478894234, alpha: 1)
