导航栏中的多个Barbutton在iOS6上不显示

Question

我使用属性rightBarButtonItems向导航项中添加了条形按钮数组，当我在iOS6中进行测试时，只有一个条形按钮项可见，它对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是否有任何新属性可将条形按钮数组添加到Navigationitem。

任何帮助将不胜感激，非常感谢。

如果要在NavigationBar的rightBarButtonItems上添加multiButton，请在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，将第二个按钮添加到第一个按钮的另一侧。
