Detail disclosure button reveals additional details or functionality related to an item. It reveals a separate view that contains additional information or functionality related to a specific item. Here's an example of a disclosure button providing additional function out when you tap this button, besides the number in the recent step of your phone app shows you the additional information about the color and some more functions like sending a message. When a detail disclosure button appears in a table role, tapping elsewhere in the row doesn't activate the detail disclosure button. It either does nothing selects the row item, or results in any other specific app defined behavior. So you need to tap directly on the icon to activate each action.

If you want people to tap the entire road to see additional detail Don't use the detail disclosure button. Instead use a detail disclosure accessory control, which appears as a chevron. Typically, use the detail disclosure button in the table view to give users a way to see more details of functionality related to all these items. However, you can also use this element in other types of views to give users a way to see more information or functionality related to an item in that view. For example, here we have the detail disclosure button in the toolbar and in a navbar. The detail disclosure button can reveal the details or functionality in a popover model view or in a separate view.
