1.设置图片(选中以及未选中)
UITabBarItem *TuiJianItem=[[UITabBarItem alloc]initWithTitle:@"我的" image:[[UIImage imageNamed:@"index_bottom07_"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal] selectedImage:[[UIImage imageNamed:@"index_bottom08_"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];
2.设置选中状态字体颜色
[tabBarItem setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
[UIFont fontWithName:@"Helvetica-Bold" size:10],
NSFontAttributeName,[UIColor colorWithRed:153/255.0 green:153/255.0 blue:153/255.0 alpha:1],NSForegroundColorAttributeName,
nil] forState:UIControlStateNormal];
3.常规设置
UITabBarController *tabBar=[[UITabBarController alloc]init];
tabBar.viewControllers=@[_homeNav,_erShouNav,_orderNav,_tuiJianNav];
tabBar.view.backgroundColor = [UIColor whiteColor];
tabBar.selectedIndex = 0;//默认展示页
tabBar.delegate=self;
