第一.Reachability 方法

_1.导入 Reachability.h 和 Reachability.m 文件 (自行下载)__2.相关控制器导入头文件和库文件 SystemConfiguration.framework__3.创建相关属性:_@property (nonatomic, strong) Reachability *reachability; _4.相关申明:_[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(reachabilityChanged:) name:kReachabilityChangedNotification object:nil]; self.reachability = [Reachability reachabilityWithHostname:@"www.baidu.com"]; [self.reachability startNotifier]; _5.相关方法:__5.相关方法:_#pragma mark - 私有方法//实时监听网络状态 - (void)reachabilityChanged:(NSNotification *)notification { Reachability* curReach = [notification object]; NSParameterAssert([curReach isKindOfClass:[Reachability class]]); [self updateInterfaceWithReachability:curReach]; }- (void)updateInterfaceWithReachability:(Reachability *)reachability { if (reachability == _reachability) { NetworkStatus netStatus = [reachability currentReachabilityStatus]; switch (netStatus) { case NotReachable:{ NSLog(@"没有网络！"); UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"友情提醒" message:@"暂无网络!请检查网络!" preferredStyle:UIAlertControllerStyleAlert]; [alert addAction:[UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) { [SVProgressHUD showWithStatus:@"数据恢复中!"]; }]]; [self presentViewController:alert animated:true completion:nil]; break; } case ReachableViaWWAN: { NSLog(@"4G/3G"); [self loadingWeb]; [SVProgressHUD dismiss]; break; } case ReachableViaWiFi: { NSLog(@"WiFi"); [self loadingWeb]; [SVProgressHUD dismiss]; break; } } } }

【iOS-网络相关】第二.从状态栏中获取网络类型，(弊端:手机无sim卡时,无法读取)：

- (NSString *)getNetWorkStates{ UIApplication *app = [UIApplication sharedApplication]; NSArray *children = [[[app valueForKeyPath:@"statusBar"]valueForKeyPath:@"foregroundView"]subviews]; NSString *state = [[NSString alloc]init]; int netType = 0; //获取到网络返回码 for (id child in children) { if ([child isKindOfClass:NSClassFromString(@"UIStatusBarDataNetworkItemView")]) { //获取到状态栏 netType = [[child valueForKeyPath:@"dataNetworkType"]intValue]; switch (netType) { case 0: state = @"无网络"; //无网模式 break; case 1: state =@"2G"; break; case 2: state =@"3G"; break; case 3: state =@"4G"; break; case 5: { state =@"wifi"; break; default: break; } } } //根据状态选择 } return state; }
