Question

I’ve two ViewController from first i’ve added two bar buttons to second ViewController. code here- `

self.navigationItem.leftBarButtonItem =
[[[UIBarButtonItem alloc]
  initWithBarButtonSystemItem:UIBarButtonSystemItemCancel
  target:self
  action:@selector(backBtnAction)] autorelease];
self.navigationItem.rightBarButtonItem =
[[[UIBarButtonItem alloc]
  initWithBarButtonSystemItem:UIBarButtonSystemItemDone
  target:callListViewCtrObj
  action:@selector(saveListNameAction)] autorelease];
self.navigationItem.rightBarButtonItem.tintColor = [UIColor blueColor];` 

Now i want to remove these two buttons when done button clicked(i.e. saveListNameAction of callListViewCtrObj is called, see the code above), i’ve tried like this- homeViewCtrObj.navigationItem.leftBarButtonItem = nil;
homeViewCtrObj.navigationItem.rightBarButtonItem =nil;
where homeViewCtrObj is object of first view controller.

Any suggestion or sample code will be appreciated.
Thanks.

Answer 1

In CallListViewCtr create a property for HomeViewCtr

@property (nonatomic, assign) HomeViewCtr *homeView;

Now when you push this view makes sure to assign the newly created viewController to this property.

self.homeView = theNewViewControllerImAboutToPush;

Now you can use

self.homeView.navigatioItem.leftBarButtonItem = nil;
self.homeView.navigatioItem.rightBarButtonItem = nil;

I think you’ll want to set homeView to nil when your done.
