二、工程图

 

三、代码

AppDelegate.h

#import <UIKit/UIKit.h>
#import "Reachability.h"
@interface AppDelegate : UIResponder <UIApplicationDelegate>
{
   Reachability *reachability;
   BOOL WarningViaWWAN;
}
@property (span, nonatomic) UIWindow *window;
- (void)ReachabilitySniff:(Reachability*) curReach;
- (void)ReachabilitySniffNotification:(NSNotification* )notification;
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex;
@end

AppDelegate.m

#import "AppDelegate.h"
#import "RootViewController.h"
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
  self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
  // Override point for customization after application launch.
  RootViewController *rootVC=[[RootViewController alloc]init];
  UINavigationController *nav=[[UINavigationController alloc]initWithRootViewController:rootVC];
  self.window.rootViewController=nav;
  //启动网络嗅探功能
  WarningViaWWAN = TRUE;
  [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(ReachabilitySniffNotification:) name:kReachabilityChangedNotification object:nil];
  if (!reachability) {
    reachability = [Reachability reachabilityForInternetConnection];
  }

  self.window.backgroundColor = [UIColor whiteColor];
  [self.window makeKeyAndVisible];
  return YES;
}
#pragma mark -网络嗅探
- (void)ReachabilitySniffNotification:(NSNotification* )notification

    }
    case ReachableViaWWAN:

      [alert show];
      break;
    }
  }
}
