ios关于故事版的tabbar自定义

tabbarC.h

#import 

@interface tabbarC : UITabBarController

@end

tabbarC.m

#import "tabbarC.h"
#import "TabBar.h"
#import "Masonry.h"

@interface tabbarC ()

@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 
@protocol TabBarDelegate
-(void)selectindex:(NSInteger)index;

@end
@interface TabBar : UIViewController
@property (nonatomic, retain) id  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
