Answer 1

将工具栏视为您的容器，而不是UIView对象。和因为UIToolBar是基于UIView的，所以可以添加到右侧导航栏使用上述技巧。该以下代码显示了如何添加右边有两个标准按钮侧：

// create a toolbar to have two buttons in the right
UIToolbar* tools = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 133, 44.01)];

// create the array to hold the buttons, which then gets added to the toolbar
NSMutableArray* buttons = [[NSMutableArray alloc] initWithCapacity:3];

// create a standard "add" button
UIBarButtonItem* bi = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:NULL];
bi.style = UIBarButtonItemStyleBordered;
[buttons addObject:bi];
[bi release];

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

// create a standard "refresh" button
bi = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh target:self action:@selector(refresh:)];
bi.style = UIBarButtonItemStyleBordered;
[buttons addObject:bi];
[bi release];

// stick the buttons in the toolbar
[tools setItems:buttons animated:NO];

[buttons release];

// and put the toolbar in the nav bar
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:tools];
[tools release];

Answer 2

您可以在leftBarButton中使用带有两个按钮的视图 -

UIBarButtonItem *leftBarButton = [[UIBarButtonItem alloc] initWithCustomView:leftBtnsView];

Answer 3

我建议使用UISegmentedControl来保存所有按钮并使用 [[UIButton alloc] initWithCustomView:]显示细分受众群。

Answer 4

以下是您如何进行此操作的示例。我使用的是此示例顶部导航栏附带的MasterDetailView模板：

- (void)viewDidLoad
{
    [super viewDidLoad];
    UIBarButtonItem *leftButton = [[UIBarButtonItem alloc] init];
    UIBarButtonItem *rightButton = [[UIBarButtonItem alloc] init];
    leftButton.title = @"Left button";
    rightButton.title = @"right button";
    self.navigationItem.leftBarButtonItem = leftButton;
    self.navigationItem.rightBarButtonItem = rightButton;
}

Answer 5

你可以这样做，有一种叫做UINavigationItem.rightBarButtonItems的东西

UIBarButtonItem * settingsButton = [[UIBarButtonItem alloc]   initWithImage：[UIImage imageNamed：@“xxx.png”] style：UIBarButtonItemStyleDone target：self action：@selector（something）];

UIBarButtonItem * menuButton = [[UIBarButtonItem alloc]   initWithImage：[UIImage imageNamed：@“xxx.png”]   style：UIBarButtonItemStyleDone target：self   动作：@selector（东西）];

self.navigationItem.rightBarButtonItems = @ [settingsButton，menuButton];

Answer 6

我认为你需要这样的东西

 UIBarButtonItem *firstButton = [[UIBarButtonItem alloc] initWithTitle:@"First" style:UIBarButtonItemStyleBordered target:self action:nil];
 UIBarButtonItem *secondButton = [[UIBarButtonItem alloc] initWithTitle:@"Second" style:UIBarButtonItemStyleBordered target:self action:nil];
 self.navigationController.navigationItem.leftBarButtonItems=@[firstButton, secondButton];

它会在导航栏左侧添加两个条形按钮项。你可以用同样的方式在右边做它

self.navigationController.navigationItem.rightBarButtonItems=@[firstButton, secondButton];
