QBKOverlaMenuView

It's basically an UIView object that tries to mimic the behavior of the floating control used by [http://sparrowmailapp.com/iphone.php](Sparrow for iOS). The control appears at the bottom right corner of the screen and it unfolds a menu whenever it's touched.

Please, take in consideration that I've coded this control as a mrere excercise so the options are not too customizable nor the code is intended to be final. It's currently designed to work in portrait orientation and it can be positioned either at the bottom or at the top of the screen. You can add an offset to avoid overlapping with UITabBar, UINavigationBar or similar controls.

To make it work, you only need to include the .h file wherever you intend to use the control and instantiate it this way —usually, from a view controller:

QBKOverlayMenuView *qbkOverlayMenu = [[QBKOverlayMenuView alloc] initWithDelegate:self position:kQBKOverlayMenuViewPositionBottom];
[qbkOverlayMenu setParentView:[self view]];

[qbkOverlayMenu addButtonWithImage:[UIImage imageNamed:@"boton1.png"] index:0];
[qbkOverlayMenu addButtonWithImage:[UIImage imageNamed:@"boton2.png"] index:1];
[qbkOverlayMenu addButtonWithImage:[UIImage imageNamed:@"boton3.png"] index:2];
[qbkOverlayMenu addButtonWithImage:[UIImage imageNamed:@"boton4.png"] index:3];

The setParentView: method indicates the view where QBKOverlayMenuView will be positioned —usually, the main view of the view controller.

Positioning

There are two constants available to indicate the positioning of the control:

• kQBKOverlayMenuViewPositionBottom: the control positions itself at bottom-right corner of the screen.
• kQBKOverlayMenuViewPositionTop: the control positions itself at top-right corner of the screen.

Offset

If you need the control to appear displaced from the bounds of the container view —usually not to overlap some kind of UITabBar, UINavigationBar…— you can do this:

QBKOverlayMenuViewOffset offset;
offset.bottomOffset = 44;
offset.topOffset = 44;

QBKOverlayMenuView *qbkOverlayMenu = [[QBKOverlayMenuView alloc] initWithDelegate:self position:kQBKOverlayMenuViewPositionBottom offset:offset];

Adding buttons

You just have to make use of the addButtonWithImage:index: method. Then, when the button is touched, the message overlayMenuView:didActivateAdditionalButtonWithIndex: will be sent with the index of the touched button to the delegate specified in the init method.

- (void)overlayMenuView:(QBKOverlayMenuView *)overlayMenuView didActivateAdditionalButtonWithIndex:(NSInteger)index
{
	NSLog(@"Button touched with index: %d", index);
}

Graphics

I've attached the graphics I created trying to mimic the aspect of those used by Sparrow. I've only created one additional icon instead of the whole set that Sparrow offers.
