FDStatusBarNotifier is a UIView subclass that lets you display notifications using the space in which the status bar resides.

It’s as easy to use as UIAlertView, here is an example:

// from a view controller
FDStatusBarNotifierView *notifierView = [[FDStatusBarNotifierView alloc] initWithMessage:@"Hi"];
notifierView.timeOnScreen = 3.0;
[notifierView showInWindow:self.view.window];

When you call showInWindow: the status bar disappear and the notifier view takes its place with a smooth animation.

How to use it

To use it just drag and drop FDStatusBarNotifierView.h and FDStatusBarNotifierView.m in your project, import the .h file in your view controller implementation and use the code shown in the example above.

More

• If you set the shouldHideOnTap property to YES when the user touch the message it will be hidden.
• If the message you want to display doesn’t fit in the status bar it will be animated and scroll horizontally to display the full text.

Optional delegate methods

I've also created some handy self-explanatory delegate methods, if you need them.

- (void)willPresentNotifierView:(FDStatusBarNotifierView *)notifierView;  // before animation and showing view
- (void)didPresentNotifierView:(FDStatusBarNotifierView *)notifierView;   // after animation
- (void)willHideNotifierView:(FDStatusBarNotifierView *)notifierView;     // before hiding animation
- (void)didHideNotifierView:(FDStatusBarNotifierView *)notifierView;      // after animation
- (void)notifierViewTapped:(FDStatusBarNotifierView *)notifierView;       // user tap the status bar message

Contributors

• ZachOrr: iPad support, hide on tap, better handling of device’s screen sizes.
• dbsGen: if the message to display doesn’t fit in the status bar, it will scroll horizontally.

TO DO

• Add support for multiple orientations (currently only portrait is supported).
• Properly manage the animation queue, to avoid unexpected behavior when showInWindow: is called multiple times.
