how to disable a navigation bar button item in iOS

Question

I have created a navigation controller. In the second view (which is pushed), I have some webservice call and placing a overlay view and setting

self.view.use

Answer 1

I solved this by just adding a property to my viewcontroller:

@property (nonatomic, strong) IBOutlet UIBarButtonItem * RightButton;

I then connected it to the button on the storyboard. You can then at will set its properties like:

self.RightButton.enabled=true;
