How do I add a UITtoolbar to my main view.nib?

Ho开发者_如何转开发w do I add using the InterfaceBuilder?

If you already have a UINavigationController, it's preferable to use its built-in toolbar.

In Interface Builder, check "Shows Toolbar" in your Navigation Controller's properties, and then use the toolbarItems attribute in your view controllers to populate the toolbar:

self.toolbarItems = [NSArray arrayWithObjects:...];

If you don't have a UINavigationController, you can drag a UIToolbar in from the library. I usually set its frame in the nib using the snap to guides feature. Then you can set the items with the method that @Can Berk Güder gives. Using UIBarButtonSystemItemFlexibleSpace and/or UIBarButtonSystemItemFixedSpace you can get a pretty good arrangement of buttons.

If you're doing it this way, just declare a UIToolbar* toolbar and set @property (nonatomic, retain) IBOutlet UIToolbar* toolbar in the interface of your view controller. In the implementation just @synthesize toolbar;. You can set the items in viewDidLoad and link the toolbar to your nib file by adding a new referencing outlet to 'toolbar' in File's Owner.
