网络状态监测

IOS开发过程中网络状态的监测
(1) 苹果自带的Reachability
注意:Build Phases 中的 Compile Sources中Reachability.m设置

核心代码:

@property (nonatomic, strong) Reachability *reach;- (void)viewDidLoad {    [super viewDidLoad];    //发送状态改变的通知    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(networkStatusChanged) name:kReachabilityChangedNotification object:nil];    //获取Reachability对象    _reach = [Reachability reachabilityForInternetConnection];    //开始监听网络    [self.reach startNotifier];   }- (void)dealloc{    [self.reach stopNotifier];    [[NSNotificationCenter defaultCenter] removeObserver:self];}- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event{    [self checkNetworkState];}- (void)networkStatusChanged{    NSLog(@"网络状态改变");       [self checkNetworkState];}/** 监听网络改变 */- (void)checkNetworkState{    if ([self isWifi]){        NSLog(@"WIFI");    }else if([self isWan]){        NSLog(@"WAN");    }else{        NSLog(@"无网络连接");    }}/** 判断是否为wifi */- (BOOL)isWifi{    Reachability *wifi = [Reachability reachabilityForLocalWiFi];    //获取当前的状态    NetworkStatus wifiStatus = wifi.currentReachabilityStatus;    if (wifiStatus != NotReachable) {        return YES;    }else{        return NO;    }}/** 判断是否为WAN */- (BOOL)isWan{    Reachability *wan = [Reachability reachabilityForInternetConnection];    NetworkStatus wanStatus = wan.currentReachabilityStatus;    if (wanStatus != NotReachable) {        return YES;    }else{        return NO;    }}

2 用 AFNetworking 框架中的 AFNetworkReachabilityManager 实现网络状态监听:

@property (nonatomic, strong) AFNetworkReachabilityManager *mgr;- (void)afnStatus{    self.mgr = [AFNetworkReachabilityManager manager];    [self.mgr setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {        switch (status) {            case AFNetworkReachabilityStatusUnknown:                NSLog(@"未知原因");                break;            case AFNetworkReachabilityStatusNotReachable:                NSLog(@"无网络连接");                break;            case AFNetworkReachabilityStatusReachableViaWiFi:                NSLog(@"WIFI");                break;            case AFNetworkReachabilityStatusReachableViaWWAN:                NSLog(@"WAN");                break;            default:                break;        }    }];    [self.mgr startMonitoring];}- (void)dealloc{    [self.mgr stopMonitoring];}
