Question

我是新到的。我在我的iPad应用观点中建立了一条航道。我不需要导航控制员,因为我为什么只增加了航道。现在我想在这条航道上添加纽吨。我做了很多尝试,但没有成功。是否可能只添加带纽子的航道? 如果是的话,我会提出一些样本代码。

“无航管或需要。 i 只想增加一条航道......

下面是我的代码,即写在观点上增加导航条码。

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

预告......。

Answer 1

I used the Interface Builder to make a static tableView in a UITableViewController. This UITableViewController is shown modally. Then I added a NavigationBar without the UINavigationController behind it as follows:

//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];

I hope this helps somebody!

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];

您可以在航道上添加以下各点:

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];
