通过你的好问题，我从上面的 Lalit Kumar 链接得到了解决方案。

Add following two libraries in your project

     1. UIButton+Badge.h and UIButton+Badge.m
     2. UIBarButtonItem+Badge.h and  UIBarButtonItem+Badge.m


Also import 

      #import "UIButton+Badge.h"
      #import "UIBarButtonItem+Badge.h"  in required view controller.


 in your required ViewController.m

      UIImage *image2 = [UIImage imageNamed:@"someImage"];
      UIBarButtonItem *navRightButton = [[UIBarButtonItem alloc] initWithImage:image2
                                                                  style:UIBarButtonItemStylePlain
                                                                 target:self
                                                                 action:@selector(buttonPress:)];
     self.navigationItem.leftBarButtonItem = navRightButton;
     self.navigationItem.leftBarButtonItem.badgeValue = @"2";
     self.navigationItem.leftBarButtonItem.badgeBGColor = [UIColor orangeColor]; //Whatever you want just change the color
