iOS开发|Xcode 13编译项目 iOS15适配 UINavigationBar和UITabBar设置无效,变成黑色

【iOS开发|Xcode 13编译项目 iOS15适配 UINavigationBar和UITabBar设置无效,变成黑色】1.今天更新了xcode13,运行项目发现iOS15以上的手机导航栏和状态栏之前设置的颜色等属性都不起作用了,都变成了黑色,滚动的时候才能变成正常的颜色,经确认得用UINavigationBarAppearance和UITabBarAppearance这两个属性对导航栏和状态栏设置才能生效。以下是示例代码(仅是背景颜色),具体属性根据自己实际情况进行设置

if (@available(iOS 15.0, *)) { UINavigationBarAppearance * bar = [UINavigationBarAppearance new]; bar.backgroundColor = [UIColor blueColor]; bar.backgroundEffect = nil; self.navigationController.navigationBar.scrollEdgeAppearance = bar; self.navigationController.navigationBar.standardAppearance = bar; UITabBarAppearance * bar2 = [UITabBarAppearance new]; bar2.backgroundColor = [UIColor whiteColor]; bar2.backgroundEffect = nil; self.tabBarController.tabBar.scrollEdgeAppearance = bar2; self.tabBarController.tabBar.standardAppearance = bar2; } else { // Fallback on earlier versions }
