给app加上时间限制

       NSDate *  senddate=[NSDate date];
          NSCalendar  * cal=[NSCalendar  currentCalendar];
          NSUInteger  unitFlags=NSDayCalendarUnit|NSMonthCalendarUnit|NSYearCalendarUnit;
          NSDateComponents * conponent= [cal components:unitFlags fromDate:senddate];
          NSInteger year=[conponent year];
          NSInteger month=[conponent month];
          NSInteger day=[conponent day];
         int dayNum = year*10000+month*100+day;
         if(dayNum>20130222&&dayNum<20130310)
          {
          if(g_sqlite==nil)
           {
              g_sqlite = [[CSqlite alloc]init];
              [g_sqlite openSqlite];
           }
          }
         else{
              UIAlertView *alert = [[UIAlertView alloc]initWithTitle:nil message:@"您当前使用的是测试版本,已过测试期限,请联系开发商" delegate:self cancelButtonTitle:@"确定" otherButtonTitles: nil];
              [alert show];
          }
