Answer 1

由于从this blog post得出：

认为一个工具栏为您的容器，而不是 的UIView的对象。由于UIToolBar基于UIView，因此可以使用上述技巧将 添加到导航栏右侧的 。该 下面的代码演示了如何添加 两个标准按键向右 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

您可以使用视图具有两个按钮在你左边巴顿 -

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:]来显示段控制。

Answer 4

下面是你如何去做这件事的一个例子。我使用的是随此示例的顶部导航栏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

你可以做这样的事情，有一些所谓的UINavigationItem.rightBarButtonItems

的UIBarButtonItem * settingsButton = [[的UIBarButtonItem [] UIImageNameName：@“xxx.png”] style：UIBarButtonItemStyleDone target：self action：@selector（something）];

的UIBarButtonItem *菜单按钮= [[ALLOC的UIBarButtonItem] initWithImage：[UIImage的imageNamed：@ “xxx.png”] 样式：UIBarButtonItemStyleDone目标：自 动作：@selector（东西）];

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

Answer 6

我认为你需要像这样

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]; 

它将在左侧导航栏中的添加两个栏按钮的项目。你可以用同样的方式使它在右侧

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