[英]iPadOS 15 UITabBar title cut off
由于我升级了我的 iPad 操作系统,我的应用程序的 UITabBar 的标题显示被截断,如屏幕截图所示。
我尝试了一些方法,但我没有找到正确的解决方案。
希望可以有人帮帮我。
这是代码:
func setupTabBar() {
if #available(iOS 13, *) {
let appearance = tabBar.standardAppearance
appearance.configureWithOpaqueBackground()
appearance.backgroundImage = UIImage(color: .white)
appearance.shadowImage = UIImage(color: .clear)
let normalAttrs: [NSAttributedString.Key: Any] = [.foregroundColor: ThemeColor.gray]
let selectedAttrs: [NSAttributedString.Key: Any] = [.foregroundColor: ThemeColor.red]
appearance.stackedLayoutAppearance.selected.titleTextAttributes = selectedAttrs
appearance.stackedLayoutAppearance.normal.titleTextAttributes = normalAttrs
appearance.inlineLayoutAppearance.selected.titleTextAttributes = selectedAttrs
appearance.inlineLayoutAppearance.normal.titleTextAttributes = normalAttrs
appearance.compactInlineLayoutAppearance.selected.titleTextAttributes = selectedAttrs
appearance.compactInlineLayoutAppearance.normal.titleTextAttributes = normalAttrs
UITabBar.appearance().standardAppearance = appearance
} else {
tabBar.backgroundImage = UIImage(color: .white)
tabBar.shadowImage = UIImage(color: .clear)
}
if #available(iOS 15, *) {
UITabBar.appearance().scrollEdgeAppearance = UITabBar.appearance().standardAppearance
}
}
出于某种原因,似乎设置titleTextAttributes
是导致问题发生的原因inlineLayoutAppearance
,并且包括NSParagraphStyle.default
的默认段落样式修复了它。
对于您的代码,以下更改应该可以修复它(从 iOS 15.0 开始)。
let normalAttrs: [NSAttributedString.Key: Any] = [.foregroundColor: ThemeColor.gray, .paragraphStyle: NSParagraphStyle.default]
let selectedAttrs: [NSAttributedString.Key: Any] = [.foregroundColor: ThemeColor.red, .paragraphStyle: NSParagraphStyle.default]
对于那些不能有默认段落样式的人,为大多数州设置属性可以让操作系统为我正确调整标签大小。
斯威夫特 5.0:
UITabBarItem.appearance()
.setTitleTextAttributes(
customAttributesWithCustomParagraphStyle,
for: [
.normal,
.highlighted,
.disabled,
.selected,
.focused,
.application,
]
)
如果不将其设置为至少.normal
和.selected
,则 UITabBarItem 标题在与自定义属性一起使用时会被截断。
