私は2つのカスタム右バーボタンアイテムを持っており、ポートレートモードでは互いにオーバーレイし、そのうちの1つだけが表示されますが、ランドスケープモードでは両方が表示されます. 項目は、背景画像付きの UIButton であるカスタム ビューで作成されます。

optionsBUtton=[UIButton buttonWithType:UIButtonTypeCustom];
[optionsBUtton setImage:[UIImage imageNamed:@"optionsIcon.png"] forState:UIControlStateNormal];
[optionsBUtton setBackgroundImage:[UIImage imageNamed:@"optionsBtn.png"] forState:UIControlStateNormal];
[optionsBUtton sizeToFit];
UIBarButtonItem* btnOptions=[[UIBarButtonItem alloc] initWithCustomView:optionsBUtton];

searchButton=[UIButton buttonWithType:UIButtonTypeCustom];
    [searchButton setImage:[UIImage imageNamed:@"searchIcon.png"] forState:UIControlStateNormal];
    [searchButton setBackgroundImage:[UIImage imageNamed:@"optionsBtn.png"] forState:UIControlStateNormal];
    [searchButton sizeToFit];
    UIBarButtonItem* btnSearch=[[UIBarButtonItem alloc] initWithCustomView:searchButton]; 

rightButtonItems=[[NSArray alloc] initWithObjects:btnOptions,btnSearch, nil];
    navItem.rightBarButtonItems=rightButtonItems;

ツールバーを使用し、ツールバーにボタンを設定する必要があります ここにコード例があります

// create a toolbar where we can place some buttons
UIToolbar* toolbar = [[UIToolbar alloc]
                        initWithFrame:CGRectMake(0, 0, 100, 45)];
[toolbar setBarStyle: UIBarStyleBlackOpaque];

// create an array for the buttons
NSMutableArray* buttons = [[NSMutableArray alloc] initWithCapacity:3];

// create a standard save button
UIBarButtonItem *saveButton = [[UIBarButtonItem alloc]
    initWithBarButtonSystemItem:UIBarButtonSystemItemSave
    target:self
    action:@selector(saveAction:)];
saveButton.style = UIBarButtonItemStyleBordered;
[buttons addObject:saveButton];
[saveButton release];

// create a spacer between the buttons
UIBarButtonItem *spacer = [[UIBarButtonItem alloc]
    initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace
    target:nil
    action:nil];
[buttons addObject:spacer];
[spacer release];

// create a standard delete button with the trash icon
UIBarButtonItem *deleteButton = [[UIBarButtonItem alloc]
    initWithBarButtonSystemItem:UIBarButtonSystemItemTrash
    target:self
    action:@selector(deleteAction:)];
deleteButton.style = UIBarButtonItemStyleBordered;
[buttons addObject:deleteButton];
[deleteButton release];

// put the buttons in the toolbar and release them
[toolbar setItems:buttons animated:NO];
[buttons release];

// place the toolbar into the navigation bar
self.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc]
                                           initWithCustomView:toolbar] autorelease];
[toolbar release];

ありがとう..！
