Navigate on clicking the tab bar item

Here I have explained that how to navigate on clicking tab bar item:-

1) In .h file add UITab bar Delegate :-

@interface StylistViewController : UIViewController<UITabBarDelegate,UITabBarControllerDelegate>

{

     

    IBOutlet UITabBar *bottomBar;

}

@property(nonatomic,retain)UITabBar *bottomBar;

2) On delegate assign delegate to self :- 

- (void)viewDidLoad

{

    [super viewDidLoad];

    

    bottomBar.delegate=self;

}

3) This is a delegate of UITab bar :-

Assign every item you add on tab bar a tag in properties -

- (void)tabBar:(UITabBar *)bottomBar didSelectItem:(UITabBarItem *)item

{

  

    NSUInteger getTagOfTabBr=item.tag;

    NSLog(@"%d",getTagOfTabBr);

    switch (getTagOfTabBr) {

        case 1:

        {

           Category *major=[[Category alloc]initWithNibName:@"Category" bundle:nil];

            [self.navigationController pushViewController:major animated:YES];

            break;

        }

        default:

            break;

    } 

}
