Disable tap on current Tab (UITabBarController) iPhone App

ios, iphone, uitabbarcontroller

Solution

You tried `tabBarController:shouldSelectViewController:` delegate method? I hope that should help you.

- (BOOL)tabBarController:(UITabBarController *)tabBarController shouldSelectViewController:(UIViewController *)viewController {

    id currentViewController = tabBarController.selectedViewController;
    return (viewController != currentViewController);
}

If all the view controllers of the tab bar controller are `UINavigationControllers`, you should do it like this.

- (BOOL)tabBarController:(UITabBarController *)tabBarController shouldSelectViewController:(UIViewController *)viewController {

    id nextVC = [(UINavigationController *)viewController topViewController];
    id currentVC = [(UINavigationController *)tabBarController.selectedViewController topViewController];
    return (nextVC != currentVC);
}

For Swift 4 the delegate method looks like this:

func tabBarController(_ tabBarController: UITabBarController, shouldSelect viewController: UIViewController) -> Bool {
    return viewController != tabBarController.selectedViewController
}

Problem

Currently, Tapping on the same Tab (in which user is working), The App moves to the very first page of that Tab. I want to disable the tap event on the Tab in which user is working currently. Any Hint?
