Question

我想在右侧添加两个按钮两个导航栏，一个用于设置，一个用于登录，但问题是我只搜索了一个按钮，右边是编辑，还有其他方式，我们可以制作两个按钮并给他们想要的标题。

Answer 1

UIBarButtonItem *addAttachButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(addAttachmentClicked:)];
UIBarButtonItem *sendButton = [[UIBarButtonItem alloc] initWithTitle:LS(@"Send") style:UIBarButtonItemStyleBordered target:self action:@selector(sendClicked:)];
self.navigationItem.rightBarButtonItems = @[addAttachButton,sendButton];

Answer 2

这是我在My UIViewController的实现文件（.m文件）中使用的代码

 -(void)viewDidLoad{

  [super viewDidLoad];

  //back button
  UIBarButtonItem *backButton = [[UIBarButtonItem alloc]initWithTitle:@" Back " style:UIBarButtonItemStyleBordered target:self action:@selector(backTo:)];    


  //Optional: if you want to add space between the back & login buttons
  UIBarButtonItem *fixedSpaceBarButtonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace  target:nil action:nil];
           fixedSpaceBarButtonItem.width = 12;

  //login button
  UIBarButtonItem *signIn_BarButton = [[UIBarButtonItem alloc]initWithTitle:@" SIGN IN " style:UIBarButtonItemStyleBordered target:self action:@selector(signInUser)];            

  //add all buttons to right side
  self.navigationItem.rightBarButtonItems = [NSArray arrayWithObjects:backButton, fixedSpaceBarButtonItem,signIn_BarButton, nil];

}

现在这里是两个按钮点击的方法

-(IBAction)backTo:(id)sender{

    [self.navigationController popViewControllerAnimated:YES];    
}

-(void) signInUser{

    //handle your sigin logic here
}

请！如果您需要更多帮助，请告诉我！
