tabbarC.h

#import <UIKit/UIKit.h>
    
    @interface tabbarC : UITabBarController
    
    @end

tabbarC.m

#import "tabbarC.h"
    #import "TabBar.h"
    #import "Masonry.h"
    
    @interface tabbarC ()<TabBarDelegate>
    
    @end
    
    @implementation tabbarC
    
    - (void)viewDidLoad {
        [super viewDidLoad];
        // Do any additional setup after loading the view.
        [self.tabBar removeFromSuperview];// 移除系统自带tabbar
        //self.tabBar.hidden = YES;//隐藏系统自带tabbar  两种方法都能实现让系统自带tabbar消失的效果
        TabBar *TB = [[TabBar alloc]initWithNibName:@"TabBar" bundle:nil];
        TB.delegate = self;
        [self.view addSubview:TB.view];
        [TB.view mas_makeConstraints:^(MASConstraintMaker *make) {
            make.left.right.bottom.equalTo(@0);
            make.height.equalTo(@49);
        }];
    }
    
    -(void)selectindex:(NSInteger)index {
        self.selectedIndex = index;
    }
    
    @end

创建好tabbarC类之后，在故事版里进行绑定

TabBar.h

#import <UIKit/UIKit.h>
    @protocol TabBarDelegate
    -(void)selectindex:(NSInteger)index;
    
    @end
    @interface TabBar : UIViewController
    @property (nonatomic, retain) id <TabBarDelegate> delegate;
    
    @end

TabBar.m

#import "TabBar.h"
    
    @interface TabBar ()
    
    @end
    
    @implementation TabBar
    
    - (void)viewDidLoad {
        [super viewDidLoad];
        // Do any additional setup after loading the view from its nib.
    }
    
    - (IBAction)click:(UIButton *)sender {
        [self.delegate selectindex:sender.tag];
    }
    
    @end

TabBar.xib
