1、tabbar相关
UITabBarAppearance *appearance = [[UITabBarAppearance alloc] init];
//tabBaritem title选中状态颜色
appearance.stackedLayoutAppearance.selected.titleTextAttributes = @{
NSForegroundColorAttributeName:[UIColor blueColor],
};
//tabBaritem title未选中状态颜色
appearance.stackedLayoutAppearance.normal.titleTextAttributes = @{
NSForegroundColorAttributeName:[UIColor blueColor],
};
//tabBar背景颜色
appearance.backgroundColor = [UIColor blackColor];
self.tabBarItem.scrollEdgeAppearance = appearance;
self.tabBarItem.standardAppearance = appearance;
2、navigationBar相关
UINavigationBarAppearance *appearance = [[UINavigationBarAppearance alloc] init];
appearance.backgroundColor = [UIColor blackColor];
self.navigationBar.standardAppearance = appearance;
self.navigationBar.scrollEdgeAppearance = appearance;
3、tableView相关
为了配合以前的开发习惯，我们只需要在创建实例的时候进行对间距的设置即可
if (@available(iOS 15.0, *)) {
tableView.sectionHeaderTopPadding = 0;
}
或者全局设置
if (@available(iOS 15.0, *)) {
[UITableView appearance].sectionHeaderTopPadding = 0;
}
