Why?

Apple doesn't provide an API in iOS for presenting notification banners while the app is running. For many projects the most sensible way to respond to a remote push notification would be to display that notification (in the same style it is presented if your app is not foreground) and allow the user to determine whether the notification merits a response.

What?

JCNotificationBannerPresenter allows you to display notification banners asynchronously from any piece of code in your application. It is not view/view-controller specific, you can use it directly from the AppDelegate, for example. It doesn't attempt to mimic the style of Apple's notifications; it seems better to avoid the uncanny valley presented by that endeavor. Just like Apple's notifications, however, this project slides down a banner from the middle of the status bar that times out after a set period of time and slides back up. The banner also can be dismissed by tapping on it, and a custom tap handler can be assigned to trigger some custom action.

Usage?

#import "JCNotificationBannerPresenter.h"

…

- (void) application:(UIApplication*)application didReceiveRemoteNotification:(NSDictionary*)notification {
  NSString* title = @"Push Notification";
  NSDictionary* aps = [notification objectForKey:@"aps"];
  NSString* alert = [aps objectForKey:@"alert"];
  [JCNotificationBannerPresenter enqueueNotificationWithTitle:title
                                                      message:alert
                                                   tapHandler:^{
                                                     NSLog(@"Received tap on notification banner!");
                                                   }];]
}

Installation?

This project includes a podspec for usage with CocoaPods. Simply add

pod 'JCNotificationBannerPresenter'

to your Podfile and run pod install.

Alternately, you can configure your project to include the QuartzCore (CoreGraphics already includes QuartzCore ) framework and add all of the .h and .m files in this project. If your project does not use ARC, you will need to enable ARC on these files.
