iOS开发-UITabBarController

- (void)viewDidLoad {
    [super viewDidLoad];
    
    //创建TAB的VC
    UIViewController* vc1 = [[UIViewController alloc] init];
    homeVC.view.backgroundColor = [UIColor yellowColor];

    UIViewController* vc4 = [[UIViewController alloc] init];
    mineVC.view.backgroundColor = [UIColor orangeColor];
    
    self.viewControllers = @[
        [self setTabBarVC:@"首页" image:@"h" selImage:@"h_selected" vc:vc1],
        [self setTabBarVC:@"关注" image:@"s" selImage:@"s_canteen_selected" vc:vc2],
        [self setTabBarVC:@"收藏" image:@"c" selImage:@"c_selected" vc:vc3],
        [self setTabBarVC:@"我的" image:@"me" selImage:@"me_selected" vc:vc4]

}

/// 创建TAB的VC
/// @param title 标题
/// @param image 非选择状态的图片
/// @param selImage 选择状态的图片
/// @param vc 展示的VC
-(UIViewController*)setTabBarVC:(NSString*)title image:(NSString*)image
                       selImage:(NSString*)selImage vc:(UIViewController*)vc{

    //普通状态的图片
    UIImage* normalImage = [UIImage imageNamed:image];
    //选中状态的图片
    UIImage* selectImage = [UIImage imageNamed:selImage];
    //设置文字
    vc.tabBarItem = [[UITabBarItem alloc] initWithTitle:title image:normalImage selectedImage:selectImage];

    [vc.tabBarItem setTitleTextAttributes:@{NSForegroundColorAttributeName:UIColorFromRGB(0X74C553)} forState:UIControlStateSelected];
    return vc;
}

Swift版：

/// 设置页面
    private func setUpUI(){
   
        let vc1 = UIViewController()
 
        let vc2 = UIViewController()

        let vc3 = UIViewController()
       
        let vc4 = UIViewController()
        
        self.viewControllers = [
            self.setTabBarVC(title: "首页", image: "tab_home", selectImage: "tab_home_sel", vc: vc1),
          self.setTabBarVC(title: "收藏", image: "tab_s", selectImage: "tab_s_sel", vc: vc2),
          self.setTabBarVC(title: "关注", image: "tab_g", selectImage: "tab_gt_sel", vc: vc3),
          self.setTabBarVC(title: "我的", image: "tab_mine", selectImage: "tab_mine_sel", vc: vc4)
        ]
    }
    
    /// 创建TabBar控件
    ///
    /// - Parameters:
    ///   - title: 标题
    ///   - image: 非选中状态的图片
    ///   - selectImage: 选中状态的图片
    ///   - controller: 展示的页面
    private func setTabBarVC(title:String,image:String,
                             selectImage:String,vc:UIViewController) -> UIViewController{
        //普通状态的图片
        let normalImage = UIImage.init(named: image)
        //选中状态的图片
        let selectImage = UIImage.init(named: selectImage)
        //设置文字
        vc.tabBarItem = UITabBarItem.init(title: title, image: normalImage, selectedImage: selectImage)
        
        //设置不同状态下文字的颜色
        vc.tabBarItem.setTitleTextAttributes([NSAttributedString.Key.foregroundColor : UIColor.hexIntColor(0xBEBEBE)], for: .normal)
        vc.tabBarItem.setTitleTextAttributes([NSAttributedString.Key.foregroundColor : UIColor.hexIntColor(0x1167BB)], for: .selected)
