我已经加入栏按钮来使用属性rightBarButtonItems的导航项目的阵列，它的工作好了iOS5的，当我在iOS6的测试只有一个栏按钮项目可见。

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;

有没有什么新的属性iOS6的补充栏按钮的阵列navigationitem。

任何帮助，将不胜感激，非常感谢。

如果你想在导航栏的rightBarButtonItems添加多按键，请在rightBarButtonItems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];
