A way to quickly add a notification icon to a UIView (iOS6 and up). Support

Code:

  RKNotificationHub* hub = [[RKNotificationHub alloc]initWithView:yourView]; // sets the count to 0
  [hub increment]; // increments the count to 1, making the notification visible

    pod 'RKNotificationHub'

  [hub increment];

  -(void)increment;
  -(void)incrementBy:(int)amount;
  -(void)decrement;
  -(void)decrementBy:(int)amount;
  @property (nonatomic, assign) int count; //%%% set to a certain number

Combine Actions!

  [hub increment];
  [hub pop];

  //%%% COLOR
  [hub setCircleColor:[UIColor colorWithRed:0.98 green:0.66 blue:0.2 alpha:1]
           labelColor:[UIColor whiteColor]];

  //%%% CIRCLE FRAME
  [hub setCircleAtFrame:CGRectMake(-10, -10, 30, 30)]; //frame relative to the view you set it to

  //%%% MOVE FRAME
  [hub moveCircleByX:-5 Y:5]; // moves the circle 5 pixels left and down from its current position

  //%%% CIRCLE SIZE
  [hub scaleCircleSizeBy:2]; // doubles the size of the circle, keeps the same center

  //%%% BLANK BADGE
  [hub hideCount];
  /* shoutout to imkevinxu for this suggestion */

Notification isn't showing up!

• If the hub value is < 1, the circle hides. Try calling [increment]
• Make sure the view you set the hub to is visible (i.e. did you call [self.view addSubview: yourView]?)
• Make sure you didn't call [hideCount] anywhere. Call [showCount] to counter this

It isn't incrementing / decrementing properly!

• I've written it so that any count < 1 doesn't show up. If you need help customizing this, reach out to me

The circle is in a weird place

• If you want to resize the circle, use [scaleCircleSizeBy:]. 0.5 will give you half the size, 2 will give you double
• If the circle is just a few pixels off, use [moveCircleByX: Y:]. This shifts the circle by the number of pixels given
• If you want to manually set the circle, call [setCircleAtFrame:] and give it your own CGRect

Something else isn't working properly
