I need to disabled a button when theres no text in the search bar and enable the button when there is text in it.
I presume there must be an event or a way to detect the status of the text in the search bar ?

I would utilize the UISearchBarDelegate class and implement the textDidChange method (UISearchBarDelegate reference).
You can use this to “detect” changes to the search field and change the enable state of the button as the user edits the contents of the search bar.
