Adding a play button to TabBar

Hi, how would i make a tabBar item play an audio file and NOT move to a different scene. This is for iOS with Swift.

Hi Iffat,

A way I would approach this would be using UITabBarControllerDelegate methods to prevent the viewcontroller from changing. Specifically, - tabBarController:shouldSelectViewController: method could prevent moving to a different scene.

To play the music, I would put the logic in the - tabBarController:didSelectViewController: method or using UITabBarDelegate method of tabBar:didSelectItem:.

Here's a description for UITabBarControllerDelegate according to Apples documentation:

"You can use it to determine whether specific tabs should be selected, to perform actions after a tab is selected, or to perform actions before or after the user customizes the order of the tabs"

Hope this helps! :)
