Change items in navigation bar on device rotation - ios

Question

I have custom UIBarButton items added to UINavigationBar as rightbarbuttonitems. I add two more items in UIBarButton when device goes to landscape mode. I am getting rotation call and I am correctly removing items from UIBarbuttons array based on device orientation, but my navigationbar item set never gets updates.
If i start with portrait mode, it shows what it suppose to. When I rotate to landscape new items are not added to navigation bar and vice versa extra item won't go when device go to portrait.
I am not sure how I can change navigationbaritems on device rotation. Per me I am doing all things correct.
-(void)setUpOnRotation:(BOOL)toPortrait{
_searchMessage = [[UILabel alloc] initWithFrame:CGRectMake(3.0, 0, 110, 20)];
_searchMessage.numberOfLines = 2;
_searchMessage.textColor = [UIColor blackColor];
_searchMessage.font = [UIFont systemFontOfSize:8.0];
_searchMessage.text = #"";
_searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 15, 130, 25)];
_searchBar.delegate = self;
_searchBar.showsCancelButton = NO;
UIBarButtonItem* doneButton = [BarButtons doneButtonWithTarget:self action:#selector(cancel)];
UIBarButtonItem *searchActivityItem = [[UIBarButtonItem alloc] initWithCustomView:_searchMessage];
UIBarButtonItem *searchItem = [[UIBarButtonItem alloc] initWithCustomView:_searchBar];
UIBarButtonItem *in = [BarButtons nativeButtonNamed:#"In"
title:#"In"
target:self
action:#selector(In)];
UIBarButtonItem *out = [BarButtons nativeButtonNamed:#"Out"
title:#"Out"
target:self
action:#selector(Out)];
NSMutableArray *itemsSet;
itemsSet = [NSMutableArray arrayWithObjects:in,
out,
searchItem,
searchActivityItem,
doneButton, nil];
if (toPortrait) {
if ([itemsSet containsObject:searchItem] || [itemsSet containsObject:searchActivityItem]) {
[itemsSet removeObject:searchActivityItem];
[itemsSet removeObject:searchItem];
}
}
[_searchBar release];
[searchItem release];
[_searchActivity release];
[_searchMessage release];
[searchActivityView release];
self.navigationItem.rightBarButtonItems = itemsSet;
}
- (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{
[self setUpOnRotation:UIInterfaceOrientationIsPortrait(toInterfaceOrientation)];
} -(void)viewWillAppear:(BOOL)animated{
[super viewWillAppear:animated];
[self.navigationController setNavigationBarHidden:NO animated:animated];
[self setUpOnRotation:UIInterfaceOrientationIsPortrait(self.interfaceOrientation)];}
Note: setUpOnRotaion method is called from willAnimateRotationToInterfaceOrientation and viewWillAppear with UIInterfaceOrientationIsPortrait(self.intefaceOrientation) and it does give me correct result. I have debugged.

Answer 1

In willAnimateRotationToInterfaceOrientation change cehck for orientation
if([uidevice orientaiton]statusbarorientation]){
self.naviogationite.rightbarbuttonitems = #[btn1,btn2,btn3];
}
else{
self.naviogationite.rightbarbuttonitems = #[abtn1,abtn2,abnt3];
}
u can do like this
can u do like this
NSMutableArray *itemsSet;
if(!toPortrait){
itemsSet = [NSMutableArray arrayWithObjects:in,
out,
searchItem,
searchActivityItem,
doneButton, nil];
}
if (toPortrait) {
itemsSet = [NSMutableArray arrayWithObjects:in,
out,
doneButton, nil];
}
