以编程方式添加导航栏iOS

我正在尝试使用导航栏（后退button，标题等）和选项卡栏（底部的工具栏）制作应用程序。 我使用子视图，所以我不必担心状态栏，导航栏，标签栏高度等，但我认为这是我的麻烦，因为我似乎无法弄清楚如何设置导航栏和制表符栏。

这是我的。 我究竟做错了什么？

 -(void)ViewDidLoad { UINavigationBar* navbar = [[UINavigationBar alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 50)]; UINavigationItem* navItem = [[UINavigationItem alloc] initWithTitle:@"karthik"]; // [navbar setBarTintColor:[UIColor lightGrayColor]]; UIBarButtonItem* cancelBtn = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCancel target:self action:@selector(onTapCancel:)]; navItem.leftBarButtonItem = cancelBtn; UIBarButtonItem* doneBtn = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(onTapDone:)]; navItem.rightBarButtonItem = doneBtn; [navbar setItems:@[navItem]]; [self.view addSubview:navbar]; } -(void)onTapDone:(UIBarButtonItem*)item{ } -(void)onTapCancel:(UIBarButtonItem*)item{ } 

Swift3

 let navigationBar = UINavigationBar(frame: CGRect(x: 0, y: 0, width: view.frame.size.width, height:44)) // Offset by 20 pixels vertically to take the status bar into account navigationBar.backgroundColor = UIColor.white // Create a navigation item with a title let navigationItem = UINavigationItem() navigationItem.title = "Title" // Create left and right button for navigation item let leftButton = UIBarButtonItem(title: "Save", style: .plain, target: self, action: #selector(ViewController.btn_clicked(_:))) let rightButton = UIBarButtonItem(title: "Right", style: .plain, target: self, action: nil) // Create two buttons for the navigation item navigationItem.leftBarButtonItem = leftButton navigationItem.rightBarButtonItem = rightButton // Assign the navigation item to the navigation bar navigationBar.items = [navigationItem] // Make the navigation bar a subview of the current view controller self.view.addSubview(navigationBar) func btn_clicked(_ sender: UIBarButtonItem) { // Do something } 

迅速

  // Create the navigation bar let navigationBar = UINavigationBar(frame: CGRectMake(0, 0, self.view.frame.size.width, 44)) // Offset by 20 pixels vertically to take the status bar into account navigationBar.backgroundColor = UIColor.whiteColor() navigationBar.delegate = self; // Create a navigation item with a title let navigationItem = UINavigationItem() navigationItem.title = "Title" // Create left and right button for navigation item let leftButton = UIBarButtonItem(title: "Save", style: UIBarButtonItemStyle.Plain, target: self, action: "btn_clicked:") let rightButton = UIBarButtonItem(title: "Right", style: UIBarButtonItemStyle.Plain, target: self, action: nil) // Create two buttons for the navigation item navigationItem.leftBarButtonItem = leftButton navigationItem.rightBarButtonItem = rightButton // Assign the navigation item to the navigation bar navigationBar.items = [navigationItem] // Make the navigation bar a subview of the current view controller self.view.addSubview(navigationBar) func btn_clicked(sender: UIBarButtonItem) { // Do something }

Swift版本，将其添加到viewDidLoad中：

 var doneButton = UIBarButtonItem(title: "Done", style: UIBarButtonItemStyle.Plain, target: self, action: "doneButton:") navigationItem.rightBarButtonItem = doneButton 

这在你的视图控制器类

 func doneButton(sender: UIBarButtonItem) { println(111) }
