How can we disable the button in my iphone application?

My application has one button in the navigation bar. I want it to work for only 1 user click. If he continuously clicks on it 2 or 3 times immediately after the first click, the button should not receive the next. How can i do this?

My app always crashes if the user taps it more than once. I don't want to make it multithreaded and use blocking. This is why I want to know if there is another alternative.

(If the app crashes by clicking more than once, it's a big problem.)

Since the button is on the navigation bar, it is a UIBarButtonItem, not a UIButton. UIBarButtonItem has a enabled

property that you can set to NO to disable the button.



(If it really is a UIButton, don't worry, it also has a enabled

property .)

After the user clicks the button, you can set the "on" property to "NO", and after the action completes, set it to "YES"

Fortunately, this is fairly easy to do. The UIBarItem class has an enabled property. Just set it to NO after the user hits it.
