iphone - 如何向 UINavigationController 添加右键？

Question

我正在尝试将刷新按钮添加到导航控制器的顶部栏，但没有成功。

这是标题：

@interface PropertyViewController : UINavigationController {

}

这是我尝试添加它的方式：

- (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;
}

尝试在 viewDidLoad 中执行此操作。通常，您应该将任何可能的事情推迟到那个时候，当 UIViewController 被初始化时，它可能仍然需要很长一段时间才能显示出来，早点工作并占用内存没有意义。

- (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];
}

至于为什么它目前不工作，我不能在没有看到更多代码的情况下 100% 肯定地说，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 重置的事情之间。

尝试将按钮添加到将被推送到PropertyViewController您创建的此类的视图控制器的 navigationItem。

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，这个以编程方式创建的 infoButton 将显示在导航栏中。这个想法是导航控制器从UIViewController它即将显示的内容中获取其显示信息（标题、按钮等）。您实际上并没有将按钮等直接添加到UINavigationController.

似乎有些人（比如我）可能会来这里寻找如何在 Interface Builder 中添加导航栏按钮。下面的答案显示了如何做到这一点。

将导航控制器添加到情节提要

选择您的 View Controller，然后在 Xcode 菜单中选择Editor > Embed In > Navigation Controller。

或者，您可以UINavigationBar从对象库中添加一个。

添加条形按钮项

将 aUIBarButtonItem从对象库拖到顶部导航栏。

它应该如下所示：

设置属性

您可以双击“项目”将文本更改为“刷新”之类的内容，但是您可以使用一个实际的刷新图标。只需选择 Attributes InspectorUIBarButtonItem并为System Item选择Refresh。

这将为您提供默认的刷新图标。

添加 IB 操作

控制从拖到UIBarButtonItemView Controller 以添加@IBAction.

class ViewController: UIViewController {

    @IBAction func refreshBarButtonItemTap(sender: UIBarButtonItem) {
        
        print("How refreshing!")
    }
    
}

就是这样。

“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 {

}

你可以使用这个：

self.navigationItem.rightBarButtonItem = rightSideOptionButton;

let rightSideOptionButton = UIBarButtonItem()
rightSideOptionButton.title = "Right"

这是 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

你为什么是子类UINavigationController？如果您需要做的只是向其添加一个按钮，则无需对其进行子类化。

在顶部设置一个层次结构UINavigationController，然后在根视图控制器的viewDidLoad:方法中：设置按钮并将其附加到导航项，方法是调用

[[self navigationItem] setRightBarButtonItem:myBarButtonItem];

只需复制并粘贴此 Objective-C 代码即可。

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，则可能会出现此问题。要解决此问题，需要在新视图控制器中添加“导航项”。有时会发生我们创建新的视图控制器屏幕并且它不会自动连接到“导航项”。

转到 main.storyboard。
选择那个新的视图控制器。
转到文档大纲。
检查视图控制器内容。
如果新的视图控制器没有导航项，则从以前的视图控制器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。

您还可以使用添加多个按钮rightBarButtonItems

-(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];
}

@Artilheiro：如果它是一个基于导航的项目，你可以创建 BaseViewController。所有其他视图都将继承此 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。

前任：

@interface BaseController : UIViewController {

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

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

@end // 在 BaseView.M 中

(void) setBackButtonCaption:(NSString *)caption {

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，实现这个基本视图调用方法：

@interface 登录视图 : 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];
