FDStatusBarNotifierView is a view that lets you display notifications and messages using the space in which the status bar resides.

Usage

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

// from a view controller
FDStatusBarNotifierView *notifierView = [[FDStatusBarNotifierView alloc] initWithMessage:@"Hello!"];
notifierView.timeOnScreen = 3.0; // by default it's 2 seconds
[notifierView showInWindow:self.view.window];

// or from a view controller with a navigation bar
[notifierView showAboveNavigationController:self.navigationController];

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

Installation

The easiest way to install this component is via CocoaPods.

Add the following line to your podfile:

pod 'FDStatusBarNotifierView'

Then run the pod install command and import FDStatusBarNotifierView.h where you plan to use the notifier view.

You can also install this manually. Just drag FDStatusBarNotifierView.h and FDStatusBarNotifierView.m in your project and import the .h file where you want to use this component.

Advanced usage

Manually hide

In some circumstances (e.g. informing the user of network activities), you may want to manually hide the component.

To do so just set the manuallyHide property to YES. Then hide calling the hide method.

notifierView.manuallyHide = YES;

// do some stuff

[notifierView hide];

Hide on tap

If you set the shouldHideOnTap property to YES when the user taps the message it will be hidden.

Scrolling message

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.

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

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.
