iOS开发网络篇—网络检查

使用说明：

1.添加framework：

将SystemConfiguration.framework添加进工程。

2.下载https://developer.apple.com/library/ios/samplecode/Reachability/Reachability.zip

复制里面的Reachability.h和Reachability.m到项目中

3.添加CloNetworkUtil.h和CloNetworkUitl.m到你的项目中

在使用的地方导入CloNetworkUtil.h头文件即可

CloNetworkUtil.h代码：

view sourceprint?

01.//

02.//  CloNetworkUtil.h

03.//  NetWorkTest

04.//

07./**

08.1.添加framework：

09.将SystemConfiguration.framework 添加进工程。

10.2.下载 https://developer.apple.com/library/ios/samplecode/Reachability/Reachability.zip

11.复制里面的Reachability.h和Reachability.m到项目中

12.*/

13.

14.#import <Foundation/Foundation.h>

15.#import "Reachability.h"

16.@interface CloNetworkUtil : NSObject{

17.}

18.

19.

20.- (Reachability *)initReachability;

21.- (BOOL)getNetWorkStatus;

22.- (NSString *)getNetWorkType;

23.@end

实现如下：

view sourceprint?

01.//

02.//  CloNetworkUtil.m

03.//  NetWorkTest

04.//

05.//  Created by Cloay on 12-6-19.

07.//

08.

09.#import "CloNetworkUtil.h"

10.

11.@implementation CloNetworkUtil

12.

13.//初始化reachability

14.- (Reachability *)initReachability{

15.Reachability *reachability = [Reachability reachabilityWithHostName:@"www.baidu.com"];

16.return reachability;

17.}

18.

19.//判断网络是否可用

20.- (BOOL)getNetWorkStatus{

21.if ([[self initReachability] currentReachabilityStatus] == NotReachable) {

22.return NO;

23.}else {

24.return YES;

25.}

26.}

27.

28./**

29.获取网络类型

30.return

31.*/

32.- (NSString *)getNetWorkType

33.{

34.NSString *netWorkType;

35.Reachability *reachability = [self initReachability];

36.switch ([reachability currentReachabilityStatus]) {

37.case ReachableViaWiFi:   //Wifi网络

38.netWorkType = @"wifi";

39.break;

40.case ReachableViaWWAN:  //无线广域网

41.netWorkType = @"wwan";

42.break;

43.default:

44.netWorkType = @"no";

45.break;

46.}

47.return netWorkType;

48.}

49.

50.@end

很简单就不在说明了！效果图：
