Recently, I came across a situation where I have to force a current selected tab to remain selected in UITabBarController, when user select or tap a different tab. So i though worthy of sharing the code with all the community. To make this happen, one can use UITabBarController delegate
– (BOOL)tabBarController:(UITabBarController *)tabBarController shouldSelectViewController:(UIViewController *)viewController
According to APPLE documentation it states:
| Asks the delegate whether the specified view controller should be made active. | |
| | The tab bar controller calls this method in response to the user tapping a tab bar item. You can use this method to dynamically decide whether a given tab should be made the active tab. – (BOOL)tabBarController:(UITabBarController *)tabBarController shouldSelectViewController:(UIViewController *)viewController { if (remainActive ) { return NO; } return YES; } In above delegate method, we return false if we want our current selected tab to remain active irrespective of user tab selection and no if otherwise. |
