Can't update badge number

[nameislihong]

Can't update badge number when set badge by @Property (nonatomic, strong, readonly) UILabel *textLabel;

To solve this problem by add some codes as follow:
// The badge text.
@Property (nonatomic, copy) NSString *badgeText;

• (void) setBadgeText:(NSString *)badgeText
  {
  _badgeText = badgeText;
  self.textLabel.text = badgeText;
  [self setNeedsDisplay];
  }
