iOS13

Question

我有一个 storyboard-app，带有多个 viewController 和一个 tabBarController。到目前为止，导航栏标题的颜色是白色。现在我正在测试 Xcode 11 beta 6 和 iOS 13 beta 8，标题是黑色的。在 iOS 12 的设备上，标题仍然是白色的。我试图在情节提要中的导航控制器的导航栏中设置标题颜色。但这没有区别。我还尝试在每个视图中更改标题颜色，但有时它不起作用。在开始使用 iOS 13 进行测试时，我不得不更改代码以更改状态栏的背景颜色。代码是这样的：

self.tabBarController.title = NSLocalizedString(@"AppTitle",nil);

NSShadow *shadow = [[NSShadow alloc] init];
shadow.shadowColor = [UIColor clearColor];
shadow.shadowOffset = CGSizeMake(0, 1);

[self.navigationController.navigationBar setBarTintColor:COLOR_HEADER_LIGHT];

if (@available(iOS 13, *))
{
    UINavigationBarAppearance *navBar = [[UINavigationBarAppearance alloc] init];
    navBar.backgroundColor = COLOR_HEADER_LIGHT;
    self.navigationController.navigationBar.standardAppearance = navBar;
    self.navigationController.navigationBar.scrollEdgeAppearance = navBar;
}
else
{
    UIView *statusBar = [[[UIApplication sharedApplication] valueForKey:@"statusBarWindow"] valueForKey:@"statusBar"];
    if ([statusBar respondsToSelector:@selector(setBackgroundColor:)]) {
        statusBar.backgroundColor = COLOR_HEADER_LIGHT;
    }
}

[self.navigationController.navigationBar setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
                                                                 shadow, NSShadowAttributeName, FONT_MEDIUM_SIZE_18, NSFontAttributeName,
                                                                 COLOR_TEXT_WHITE, NSForegroundColorAttributeName, nil]];

[self.navigationController.navigationBar setTintColor:COLOR_TEXT_WHITE];

我希望任何人都知道如何将标题颜色改回白色。不调整每个控制器的最佳情况。

Answer 1

在 iOS13 中，您需要在 UINavigationBarAppearance 上设置标题颜色 object - 尝试将此行添加到您的代码中：

appearance.titleTextAttributes = [.foregroundColor: myAppLabelColor]
appearance.largeTitleTextAttributes = [.foregroundColor: myAppLabelColor]

Answer 2

iOS 13 为浅色和深色主题使用动态颜色您可以通过为浅色和深色外观创建颜色资产来设置标题颜色。

Answer 3

func manageNavigationBar(){
        if #available(iOS 13.0, *){

            let navBarAppearance = UINavigationBarAppearance()
            navBarAppearance.configureWithOpaqueBackground()
            navBarAppearance.backgroundColor = UIColor(red: 0.6157, green: 0.3412, blue: 0.8588, alpha: 1.0)
            navBarAppearance.titleTextAttributes = [.foregroundColor: UIColor.white]
            navBarAppearance.largeTitleTextAttributes = [.foregroundColor: UIColor.white]
            UINavigationBar.appearance(whenContainedInInstancesOf: [UINavigationController.self]).standardAppearance = navBarAppearance
            UINavigationBar.appearance(whenContainedInInstancesOf: [UINavigationController.self]).scrollEdgeAppearance = navBarAppearance
        }
    }

//在您的 AppDelegate 中调用此函数，也在 class 您希望导航像这样工作的地方

Answer 4

在iOS13中，我把标题颜色改成这样

UINavigationBarAppearance *appearance = [self.navigationController.navigationBar standardAppearance];
appearance.titleTextAttributes = @{NSForegroundColorAttributeName: [UIColor whiteColor]};
self.navigationController.navigationBar.standardAppearance = appearance;
self.navigationController.navigationBar.scrollEdgeAppearance = appearance;
