UIBarButtonItem programmatically

i tried to define a UIBarButtonItem programatically. it showed up in the navBar as expected. but it didn´t call the action until i went to the IB and dragged an bar button item into the navigation controller object and assigned it with the didTapSearch action.

i thought it´s possible to define UIBarButtonItems programatically only, without any additional IB work. or is that only possible if the navigation controller and/or the view controller was created programatically as well?

or did i miss to set a delegate in my code again?

UIBarButtonItem *searchBtn = [[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemSearch target:self action:@selector(didTapSearch:)] autorelease];
self.navigationItem.rightBarButtonItem = searchBtn;

Add a color to it.

searchBtn.tintColor = [UIColor blackColor];

try this way instead in the header, declare the barButtonItem

proximityButton= [[UIBarButtonItem alloc] 
                  initWithTitle:@"Nearby Locations"                                            
                  style:UIBarButtonItemStyleBordered 
                  target:self 
                  action:@selector(addToProximity)];
self.navigationItem.leftBarButtonItem = proximityButton;

and you can take out the :(id)sender part of the action

You could specific the action: method programatically as you have done with your UIBarButtonItem.

Implement action method in the class of object which you specified with target:.

-(void) didTapSearch:(id) sender
{
  UIBarButtonItem *searchBtn = (UIBarButtonItem*)sender;
}
