Question

我是iOS开发的新手。我在我的iPad应用程序视图中创建了一个导航栏。我不需要导航控制器，这就是为什么我只添加了导航栏。现在我想在导航栏中添加按钮。我尝试了很多但没有成功。是否可以仅添加带按钮的导航栏？如果是，那么建议我一些示例代码。

“我没有导航控制器或需要它。我只想在一个视图中添加导航栏。”

Bellow是我为在ViewDidLoad（）

中添加导航栏而编写的代码

UINavigationBar *navBar = [[UINavigationBar alloc] initWithFrame:CGRectMake(0, 0, 1026, 50)];
[navBar setTintColor:[UIColor blackColor]];
[navBar setDelegate:self];
[self.view addSubview:navBar];

提前致谢....

我使用Interface Builder在UITableViewController中创建静态tableView。这个UITableViewController以模态显示。然后我添加了一个没有UINavigationController的NavigationBar，如下所示：

//Creating the plain Navigation Bar
UINavigationBar *headerView = [[UINavigationBar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];

//The UINavigationItem is neede as a "box" that holds the Buttons or other elements
UINavigationItem *buttonCarrier = [[UINavigationItem alloc]initWithTitle:@"Sign-In"];

//Creating some buttons:
UIBarButtonItem *barBackButton = [[UIBarButtonItem alloc] initWithTitle:@"Zurück" style:UIBarButtonItemStyleDone target:self action:@selector(signInBackPressed:)];
UIBarButtonItem *barDoneButton = [[UIBarButtonItem alloc] initWithTitle:@"Fertig" style:UIBarButtonItemStylePlain target:self action:@selector(signInDonePressed:)];

//Putting the Buttons on the Carrier
[buttonCarrier setLeftBarButtonItem:barBackButton];
[buttonCarrier setRightBarButtonItem:barDoneButton];

//The NavigationBar accepts those "Carrier" (UINavigationItem) inside an Array
NSArray *barItemArray = [[NSArray alloc]initWithObjects:buttonCarrier,nil];

// Attaching the Array to the NavigationBar
[headerView setItems:barItemArray];

// Adding the NavigationBar to the TableView 
[self.tableView setTableHeaderView:headerView];

我希望这有助于某人！

UIBarButtonItem *bi1 = [[UIBarButtonItem alloc] initWithTitle:@"Edit" style:UIBarButtonItemStyleBordered target:self action:@selector(editButton)];

bi1.style = UIBarButtonItemStyleBordered;
bi1.tintColor = [UIColor colorWithWhite:0.305f alpha:0.0f];

self.navigationItem.rightBarButtonItem = bi1;

[bi1 release];

您可以按如下方式向导航栏添加按钮：

UIBarButtonItem *btnSave = [[UIBarButtonItem alloc] 
                                initWithTitle:@"Save"
                                style:UIBarButtonItemStyleBordered 
                                target:self 
                             action:@selector(save_Clicked:)];
 navBar.rightBarButtonItem = btnSave;
 [btnSave release];

 UIBarButtonItem *btnCancel = [[UIBarButtonItem alloc] 
                                initWithTitle:@"Cancel"                                    
                                style:UIBarButtonItemStyleBordered
                                target:self
                                action:@selector(cancel_Clicked:)];
 navBar.leftBarButtonItem = btnCancel;
 [btnCancel release];
