Add a Navigation Controller to your Storyboard

Question

我正在尝试向导航控制器的顶部栏添加刷新按钮但没有成功。

以下是标题：

@interface PropertyViewController : UINavigationController {

}

以下是我尝试添加它的方法：

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
    if (self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]) {
        UIBarButtonItem *anotherButton = [[UIBarButtonItem alloc] initWithTitle:@"Show" style:UIBarButtonItemStylePlain
                                          target:self action:@selector(refreshPropertyList:)];      
        self.navigationItem.rightBarButtonItem = anotherButton;
    }
    return self;
}

Answer 1

尝试在viewDidLoad中执行此操作。一般来说，你应该推迟任何你可以做到的事情，无论如何，当UIViewController被引入时，它仍然可能需要一段时间才显示出来，没有必要提前做好工作并占用内存。

- (void)viewDidLoad {
  [super viewDidLoad];

  UIBarButtonItem *anotherButton = [[UIBarButtonItem alloc] initWithTitle:@"Show" style:UIBarButtonItemStylePlain target:self action:@selector(refreshPropertyList:)];          
  self.navigationItem.rightBarButtonItem = anotherButton;
  // exclude the following in ARC projects...
  [anotherButton release];
}

至于为什么它当前不工作，我不能100％确定地说没有看到更多的代码，但是在init和视图加载之间发生了很多事情，你可能正在做一些导致navigationItem的事情在两者之间重置。

Answer 2

尝试将按钮添加到视图控制器的navigationItem，该按钮将被推送到您创建的此PropertyViewController类。

那是：

MainViewController *vc = [[MainViewController alloc] initWithNibName:@"MainViewController" bundle:nil];
UIButton *infoButton = [UIButton buttonWithType:UIButtonTypeInfoLight];
[infoButton addTarget:self action:@selector(showInfo) forControlEvents:UIControlEventTouchUpInside];
vc.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc] initWithCustomView:infoButton] autorelease];

PropertyViewController *navController = [[PropertyViewController alloc] initWithRootViewController:vc];

现在，以编程方式创建的infoButton将显示在导航栏中。这个想法是导航控制器从它将要显示的UIViewController中获取其显示信息（标题，按钮等）。您实际上并没有直接向UINavigationController添加按钮等。

It seems that some people (like me) may come here looking for how to add a navigation bar button in the Interface Builder. The answer below shows how to do it.

Add a Navigation Controller to your Storyboard

Select your View Controller and then in the Xcode menu choose Editor > Embed In > Navigation Controller.

Alternatively, you could add a UINavigationBar from the Object Library.

Add a Bar Button Item

Drag a UIBarButtonItem from the Object Library to the top navigation bar.

It should look like this:

Set the Attributes

You could double-click "Item" to change the text to something like "Refresh", but there is an actual icon for Refresh that you can use. Just select the Attributes Inspector for the UIBarButtonItem and for System Item choose Refresh.

That will give you the default Refresh icon.

Add an IB Action

Control drag from the UIBarButtonItem to the View Controller to add an @IBAction.

class ViewController: UIViewController {

    @IBAction func refreshBarButtonItemTap(sender: UIBarButtonItem) {

        print("How refreshing!")
    }

}

That's it.

Answer 4

“刷新”有一个默认的系统按钮：

- (void)viewDidLoad {
    [super viewDidLoad];

    UIBarButtonItem *refreshButton = [[[UIBarButtonItem alloc] 
                            initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh
                            target:self action:@selector(refreshClicked:)] autorelease];
    self.navigationItem.rightBarButtonItem = refreshButton;

}

- (IBAction)refreshClicked:(id)sender {

}

Answer 5

你可以使用它：

目标-C

UIBarButtonItem *rightSideOptionButton = [[UIBarButtonItem alloc] initWithTitle:@"Right" style:UIBarButtonItemStylePlain target:self action:@selector(rightSideOptionButtonClicked:)];          
self.navigationItem.rightBarButtonItem = rightSideOptionButton;

夫特

let rightSideOptionButton = UIBarButtonItem()
rightSideOptionButton.title = "Right"
self.navigationItem.rightBarButtonItem = rightSideOptionButton

Answer 6

对于swift 2：

self.title = "Your Title"

var homeButton : UIBarButtonItem = UIBarButtonItem(title: "LeftButtonTitle", style: UIBarButtonItemStyle.Plain, target: self, action: Selector("yourMethod"))

var logButton : UIBarButtonItem = UIBarButtonItem(title: "RigthButtonTitle", style: UIBarButtonItemStyle.Plain, target: self, action: Selector("yourMethod"))

self.navigationItem.leftBarButtonItem = homeButton
self.navigationItem.rightBarButtonItem = logButton

Answer 7

-(void) viewWillAppear:(BOOL)animated
{

    UIButton *btnRight = [UIButton buttonWithType:UIButtonTypeCustom];
    [btnRight setFrame:CGRectMake(0, 0, 30, 44)];
    [btnRight setImage:[UIImage imageNamed:@"image.png"] forState:UIControlStateNormal];
    [btnRight addTarget:self action:@selector(saveData) forControlEvents:UIControlEventTouchUpInside];
    UIBarButtonItem *barBtnRight = [[UIBarButtonItem alloc] initWithCustomView:btnRight];
    [barBtnRight setTintColor:[UIColor whiteColor]];
    [[[self tabBarController] navigationItem] setRightBarButtonItem:barBtnRight];

}

Answer 8

以下是Swift中的解决方案（根据需要设置选项）：

var optionButton = UIBarButtonItem()
optionButton.title = "Settings"
//optionButton.action = something (put your action here)
self.navigationItem.rightBarButtonItem = optionButton

Answer 9

为什么你是UINavigationController的子类？如果你需要做的就是添加一个按钮，就没有必要对它进行子类化。

在顶部设置一个UINavigationController的层次结构，然后在根视图控制器的viewDidLoad:方法中设置：设置按钮并通过调用

将其附加到导航项

[[self navigationItem] setRightBarButtonItem:myBarButtonItem];

Answer 10

你可以尝试

self.navigationBar.topItem.rightBarButtonItem = anotherButton;

Answer 11

斯威夫特4：

override func viewDidLoad() {
    super.viewDidLoad()

    navigationItem.leftBarButtonItem = UIBarButtonItem(title: "tap me", style: .plain, target: self, action: #selector(onButtonTap))
}

@objc func onButtonTap() {
    print("you tapped me !?")
}

Answer 12

试试这个。它适合我。

导航栏并将背景图像添加到右键。

 UIBarButtonItem *Savebtn=[[UIBarButtonItem alloc]initWithImage:[[UIImage    
 imageNamed:@"bt_save.png"]imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal] 
 style:UIBarButtonItemStylePlain target:self action:@selector(SaveButtonClicked)];
 self.navigationItem.rightBarButtonItem=Savebtn;

Answer 13

UIView *view = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 110, 50)];
view.backgroundColor = [UIColor clearColor];

UIButton *settingsButton =  [UIButton buttonWithType:UIButtonTypeCustom];
[settingsButton setImage:[UIImage imageNamed:@"settings_icon_png.png"] forState:UIControlStateNormal];
[settingsButton addTarget:self action:@selector(logOutClicked) forControlEvents:UIControlEventTouchUpInside];
[settingsButton setFrame:CGRectMake(40,5,32,32)];
[view addSubview:settingsButton];

UIButton *filterButton =  [UIButton buttonWithType:UIButtonTypeCustom];
[filterButton setImage:[UIImage imageNamed:@"filter.png"] forState:UIControlStateNormal];
[filterButton addTarget:self action:@selector(openActionSheet) forControlEvents:UIControlEventTouchUpInside];
[filterButton setFrame:CGRectMake(80,5,32,32)];
[view addSubview:filterButton];



self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:view];

Answer 14

将此代码用于带有赢得标题的右键导航栏，并在单击右键后调用方法。

$("#buttonid").click(function(){  

        $.ajax({
        url: "controllername/getData",
        type: "POST", 
        dataType: "json",
        data: "{id:value}",
        success: function (mydata) {
            //history.pushState('', 'checkout' + href, href); 
        }
    }); });

Answer 15

只需复制并粘贴此Objective-C代码即可。

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.
    [self addRightBarButtonItem];
}
- (void) addRightBarButtonItem {
    UIButton *btnAddContact = [UIButton buttonWithType:UIButtonTypeContactAdd];
    [btnAddContact addTarget:self action:@selector(addCustomerPressed:) forControlEvents:UIControlEventTouchUpInside];
    UIBarButtonItem *barButton = [[UIBarButtonItem alloc] initWithCustomView:btnAddContact];
    self.navigationItem.rightBarButtonItem = barButton;
}

#pragma mark - UIButton
- (IBAction)addCustomerPressed:(id)sender {
// Your right button pressed event
}

Answer 16

您还可以使用rightBarButtonItems

添加多个按钮

-(void)viewDidLoad{

    UIBarButtonItem *button1 = [[UIBarButtonItem alloc] initWithTitle:@"button 1" style:UIBarButtonItemStylePlain target:self action:@selector(YOUR_METHOD1:)];
    UIBarButtonItem *button2 = [[UIBarButtonItem alloc] initWithTitle:@"button 2" style:UIBarButtonItemStylePlain target:self action:@selector(YOUR_METHOD2:)];

    self.navigationItem.rightBarButtonItems = @[button1, button2];
}

Answer 17

如果我们删除视图控制器或尝试在界面构建器（main.storyboard）中添加新的视图控制器，则会发生此问题。要解决此问题，需要添加＆＃34;导航项＆＃34;在新视图控制器内。有时会发生我们创建新的视图控制器屏幕并且它没有连接到＆＃34;导航项目＆＃34;自动。

转到main.storyboard。
选择新视图控制器。
转到文档大纲。
检查视图控制器内容。
如果新视图控制器没有导航项，则从先前的View Controller复制导航项并将其粘贴到新的视图控制器中。
保存并清理项目。

Answer 18

您应该在- (void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated方法中添加barButtonItem。

Answer 19

    self.navigationItem.rightBarButtonItem =[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh target:self action:@selector(refreshData)];



}

-(void)refreshData{
    progressHud= [MBProgressHUD showHUDAddedTo:self.navigationController.view animated:YES];
    [progressHud setLabelText:@"拼命加载中..."];
    [self loadNetwork];
}

Answer 20

- (void)viewWillAppear:(BOOL)animated
{    
    [self setDetailViewNavigationBar];    
}
-(void)setDetailViewNavigationBar
{
    self.navigationController.navigationBar.tintColor = [UIColor purpleColor];
    [self setNavigationBarRightButton];
    [self setNavigationBarBackButton];    
}
-(void)setNavigationBarBackButton// using custom button 
{
   UIBarButtonItem *leftButton = [[UIBarButtonItem alloc] initWithTitle:@"  Back " style:UIBarButtonItemStylePlain target:self action:@selector(onClickLeftButton:)];          
   self.navigationItem.leftBarButtonItem = leftButton;    
}
- (void)onClickLeftButton:(id)sender 
{
   NSLog(@"onClickLeftButton");        
}
-(void)setNavigationBarRightButton
{

  UIBarButtonItem *anotherButton = [[UIBarButtonItem alloc] initWithTitle:@"Show" style:UIBarButtonItemStylePlain target:self action:@selector(onClickrighttButton:)];          
self.navigationItem.rightBarButtonItem = anotherButton;   

}
- (void)onClickrighttButton:(id)sender 
{
   NSLog(@"onClickrighttButton");  
}

Answer 21

    UIBarButtonItem *rightBarButtonItem = [[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(add:)];
self.navigationItem.rightBarButtonItem = rightBarButtonItem;

Answer 22

@Artilheiro：如果它是一个基于导航的项目，你可以创建BaseViewController。所有其他视图将继承此BaseView。在BaseView中，您可以定义通用方法来添加右键或更改左键文本。

例如：

@interface BaseController：UIViewController {

}    - （void）setBackButtonCaption：（NSString *）caption;

（void）setRightButtonCaption：（NSString *）caption selectot：（SEL）selector;

@end   //在BaseView.M中

（void）setBackButtonCaption：（NSString *）标题   {

UIBarButtonItem *backButton =[[UIBarButtonItem alloc] init];

backButton.title= caption;
self.navigationItem.backBarButtonItem = backButton;
[backButton release];

} - （void）setRightButtonCaption：（NSString *）caption selectot：（SEL）selector {
  UIBarButtonItem *rightButton = [[UIBarButtonItem alloc] init];

rightButton.title = caption;

rightButton.target= self;

[rightButton setAction:selector];

self.navigationItem.rightBarButtonItem= rightButton;

[rightButton release];

}

现在在任何自定义视图中，实现此基本视图调用方法：

@interface LoginView：BaseController {

在某些方法中调用基本方法为：

SEL sel = @selector（switchToForgotPIN）;

[super setRightButtonCaption：@“忘记密码”selectot：sel];
