Question

I have a Tab Bar Controller in Storyboard, connected with 2 views. In View 2 (TimelineView) I had set in .h file:

@interface Timeline_Overview : UIViewController<UITabBarDelegate>{
}
@property (nonatomic, retain) IBOutlet UITabBarItem *PostImage;

And in .m file:

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

NSLog(@"test");
if(item.tag==2)
{

    UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
    UITabBarController *TimeLine = [mainStoryboard instantiateViewControllerWithIdentifier:@"Post_Photo_One"];
    [self presentViewController:TimeLine animated:YES completion:nil];
}
else
{
    //your code
}
}

but this void does not fire :(

Here is a pic from storyboard:

Can anybody help?

EDIT:

here is my inspection It looks like yours and it does not work :(

EDIT 2:

Here my Storyboard, I have set the Custom Class to my "Timeline_Overview" from the "Post Image" tab but it does not work :(

Answer 1

Change in the connection inspector the delegate of the UITabBarController delegate in the storyboard to your relevant class, see screenshot:

and Don't forget to change the identity inspector to your custom tab bar:

Answer 2

If you are using storyboard, do this

in didFinishLaunchingWithOptions

UITabBarController *tabBar = (UITabBarController *)self.window.rootViewController;
[tabBar setDelegate:self];

Also in AppDelegate, keep <UITabBarControllerDelegate>

And then

-(void) tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController
{
   //Write your code here
}
