1.tabbar横线颜色
if (@available(iOS 13.0, *)) {
UITabBarAppearance *standardAppearance = [[UITabBarAppearance alloc] init];
standardAppearance.backgroundColor = [UIColor whiteColor];//根据自己的情况设置
standardAppearance.shadowColor = [UIColor clearColor];//也可以设置为白色或任何颜色
self.tabBar.standardAppearance = standardAppearance;
}else{
[[UITabBar appearance] setBackgroundImage:[[UIImage alloc]init]];
[[UITabBar appearance] setShadowImage:[[UIImage alloc]init]];
[UITabBar appearance].backgroundColor = [UIColor whiteColor];//根据自己的情况设置
}
2.修改tabbar背景色
- (void)setTabbarBackGround{
if(@available(iOS 13.0, *)) {
UITabBarAppearance *appearance = [self.tabBar.standardAppearance copy];
appearance.backgroundImage = [selfcreateImageWithColor:[UIColor clearColor]];
appearance.shadowImage = [selfcreateImageWithColor:[UIColor clearColor]];
//下面这行代码最关键
[appearance configureWithTransparentBackground];
self.tabBar.standardAppearance = appearance;
}else{
[self.tabBar setBackgroundImage:[selfcreateImageWithColor:[UIColor clearColor]]];
[self.tabBar setShadowImage:[selfcreateImageWithColor:[UIColor clearColor]]];
self.tabBar.translucent =YES;
}
}
3.设置tabbar字体颜色 大小
if(@available(iOS 13.0, *)) {
// iOS13 及以上
self.tabBar.tintColor = [UIColor colorWithHexString:@"#FF0009"];
self.tabBar.unselectedItemTintColor = [UIColor colorWithHexString:@"#333333"];
UITabBarItem *item = [UITabBarItem appearance];
[item setTitleTextAttributes:@{NSFontAttributeName:[UIFont systemFontOfSize:14]} forState:UIControlStateNormal];
[item setTitleTextAttributes:@{NSFontAttributeName:[UIFont systemFontOfSize:14]} forState:UIControlStateSelected];
}
else{
// iOS13 以下
UITabBarItem *item = [UITabBarItem appearance];
[item setTitleTextAttributes:@{ NSForegroundColorAttributeName:[UIColor colorWithHexString:@"#333333"],NSFontAttributeName:[UIFont systemFontOfSize:14]} forState:UIControlStateNormal];
[item setTitleTextAttributes:@{ NSForegroundColorAttributeName:[UIColor colorWithHexString:@"#FF0009"],NSFontAttributeName:[UIFont systemFontOfSize:14]} forState:UIControlStateSelected];
}
