  1. UIApplication的一个属性，就查了下API，果然找到了这个属性：
  2.  
  3. @ property(nonatomic) NSInteger applicationIconBadgeNumber;  // set to 0 to hide. default is 0
  4.  
  5.  
  6.  
  7.     就结合手上正在做的项目，看看效果（在程序退出时，显示今日要处理的事件数目）：
  8.  
  9. - (void)applicationDidEnterBackground:(UIApplication *)application{
  10.  
  11. [[UIApplication sharedApplication] setApplicationIconBadgeNumber:
  12.  
  13.            _homeViewController._dayViewController.eventCountOfToday];
  14.  
  15. }
