I am really new to iPhone development and I need help setting up my views.
I have a view that is named FirstViewController.xib
and a controller class for this view.
In my MainWindox.xib
I have setup a root controller with a moveToNextView
function that is connected to the opti开发者_C百科ons bar button item.
So when I click on this item the current view switches to the first view and I am able to swticht back. That works fine so far.
The navigation bar at the top of the screen from the MainWindow.xib
is displayed in the first view, too. But when I open FirstViewController.xib
there isn't any navigation bar defined (but on build&run it is displayed).
This is a problem for me because I want to add a save bar item to the first view. How do I solve that?
Assuming you have a UIViewController (or UIViewController subclass) that is a child of a UINavigationController. Note, I'm using storyboards so your results may vary when using xibs.
If you do not see a UINavigationBar on the interface, try manually changing the simulated metrics.
Drag a Navigation Item onto the view (anywhere). You should now have a place to enter the title in the interface builder.
- Now you can drag Bar Button Items onto the nav bar.
You have to do it from code. Add to your FirstViewController class viewDidLoad
method:
UIBarButtonItem *anotherButton = [[UIBarButtonItem alloc] initWithTitle:@"Save" style:UIBarButtonItemStyleDone target:self action:@selector(doSave:)];
self.navigationItem.rightBarButtonItem = anotherButton;
[anotherButton release];
Just drag a bar button item onto your nav bar in Interface Builder. Xcode automatically wires it up then you can use it like anything else...
