導航欄中的多個Barbutton在iOS6上不顯示

Question

我使用屬性rightBarButtonItems向導航項中添加了條形按鈕數組，當我在iOS6中進行測試時，只有一個條形按鈕項可見，它對iOS5效果很好。

UIBarButtonItem *updateButton          = [[UIBarButtonItem alloc]
                                          initWithTitle:@"Update"
                                          style:UIBarButtonItemStylePlain
                                          target:self
                                          action:@selector(updateData)];

UIBarButtonItem *refreshButton          = [[UIBarButtonItem alloc]
                                          initWithTitle:@"Refresh"
                                          style:UIBarButtonItemStylePlain
                                          target:self
                                          action:@selector(refresh)];

NSArray *arrBtns = [[NSArray alloc]initWithObjects:updateButton,refreshButton, nil];

self.navigationItem.rightBarButtonItems=arrBtns;

iOS6是否有任何新屬性可將條形按鈕數組添加到Navigationitem。

任何幫助將不勝感激，非常感謝。

如果要在NavigationBar的rightBarButtonItems上添加multiButton，請在rightBarButtonItems上使用segmentController

UISegmentedControl *segmentedControl = [[UISegmentedControl alloc] initWithItems:
                                            [NSArray arrayWithObjects:@"Add",@"Delete",
                                             nil]];
    segmentedControl.frame = CGRectMake(0, 0, 80, 30);
    segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;
    [segmentedControl setWidth:35.0 forSegmentAtIndex:0];
    [segmentedControl setWidth:45.0 forSegmentAtIndex:1];

    [segmentedControl addTarget:self action:@selector(segmentAction:) forControlEvents:UIControlEventValueChanged];
    segmentedControl.momentary = YES;

    UIBarButtonItem *segmentBarItem = [[UIBarButtonItem alloc] initWithCustomView:segmentedControl];
    [segmentedControl release];

    self.navigationItem.leftBarButtonItem = segmentBarItem;
    [segmentBarItem release];

其次，將第二個按鈕添加到第一個按鈕的另一側。
