Adding toolbars to a view

What kind of toolbars are these at the top and bottom of the view?

How are these added in the code rather than in IB?

The top portion looks like a UINavigationController presented modally from another UIViewController. The cancel button is added in the

- (void)viewDidLoad method of the view as the right navigation item.

The bottom is just a plain old UIToolBar with 4 buttons.

All UINavigationControllers have a UIToolbar built in and it's just a matter of calling the following function to display it.

[self.navigationController setToolbarHidden:NO];

If you want to create buttons, you can call...

- (void)setToolbarItems:(NSArray *)toolbarItems animated:(BOOL)animated 

to configure UIToolbar items. All the items in a UIToolbar are just an NSArray of objects. In this case your objects are buttons. In order to properly space the items in the UIToolbar there's a flexible space object that you can put between your buttons to make it look pretty. So when you setup your array of toolbar items you'd have. Button | Space | Button | Space | Button | Space | Button to accomplish the above look.

Here's some info on the UIToolbar Class Reference if you get lost.
