Question

嘿，
有没有办法将tabbar的字体设置为例如黑板？我已经看到了字体大小的问题，并尝试使用字体，但循环无法解决。

如果无法使用自定义字体，是否可以删除所有文本并使标签栏的项目覆盖整个标签？或者我可以以某种方式将imageView放在标签栏的顶部并使用标签“通过”该图像？

谢谢！

Answer 2

放入AppDelegate.m：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

以下是代码：

    NSMutableDictionary *attributes = [NSMutableDictionary dictionaryWithDictionary: [[UITabBarItem appearance] titleTextAttributesForState:UIControlStateNormal]];
[attributes setValue:[UIFont fontWithName:@"Avenir" size:10] forKey:UITextAttributeFont];
[[UITabBarItem appearance] setTitleTextAttributes:attributes1 forState:UIControlStateNormal];

在iOS 13上，UITabBarItem.appearance().setTitleTextAttributes方法存在错误，因此我们需要采取以下解决方法：

    let paragraphStyle = NSMutableParagraphStyle()
    paragraphStyle.alignment = .center
    let attributes = [NSAttributedString.Key.font: UIFont.systemFont(ofSize: 12),
                      NSAttributedString.Key.paragraphStyle: paragraphStyle]

    let appearance = UITabBarItem.appearance()
    appearance.setTitleTextAttributes(attributes, for: .normal)

    if #available(iOS 13.0, *) {
        let appearance = UITabBarAppearance()
        appearance.stackedLayoutAppearance.normal.titleTextAttributes = attributes
        appearance.stackedLayoutAppearance.normal.badgeBackgroundColor = .blue
        appearance.stackedLayoutAppearance.selected.titleTextAttributes = attributes
        appearance.stackedLayoutAppearance.selected.badgeBackgroundColor = .blue
        tabBar.standardAppearance = appearance
    }

如果仅在iOS 13上设置外观tabBar.standardAppearance = appearance，您仍然会遇到错误，而另一个错误
