RealReachability的使用心得

//关于reachability的优化版本一. 关于目前reachability的缺点1.现在很流行的公用wifi，需要网页鉴权，鉴权之前无法上网，但本地连接已经建立；2.存在了本地网络连接，但信号很差，实际无法连接到服务器；3.iOS连接的路由设备本身没有连接外网。原因: Reachability相关的框架在底层都是通过SCNetworkReachability来实现网络检测的，所以无法检测实际网络连接情况。二. 优化方法(RealReachability)链接: http://www.cocoachina.com/ios/20160224/15407.html1.集成: pod 'RealReachability'2.常用代码: * 实时监控网络连接状态的方法:[GLobalRealReachability startNotifier];[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(networkChanged:) name:@"kRealReachabilityChangedNotification" object:nil];- (void)networkChanged:(NSNotification *)notification{    RealReachability *reachability = (RealReachability *)notification.object;    ReachabilityStatus status = [reachability currentReachabilityStatus];    if (status == NotReachable) {        self.curStatusLabel.text = @"没有网络";    }    if (status == ReachableViaWiFi) {        self.curStatusLabel.text = @"WiFi网络";    }    if (status == ReachableViaWWAN) {        self.curStatusLabel.text = @"3/4G网络";    }}* 手动检测网络的方法[GLobalRealReachability startNotifier];- (IBAction)checkTheStatus:(id)sender {    [GLobalRealReachability reachabilityWithBlock:^(ReachabilityStatus status) {        switch (status)        {            case NotReachable:            {                [[[UIAlertView alloc] initWithTitle:@"提示" message:@"没有网络" delegate:self cancelButtonTitle:@"确定" otherButtonTitles:nil, nil] show];                break;            }            case ReachableViaWiFi:            {                [[[UIAlertView alloc] initWithTitle:@"提示" message:@"WIFI" delegate:self cancelButtonTitle:@"确定" otherButtonTitles:nil, nil] show];                break;            }            case ReachableViaWWAN:            {                [[[UIAlertView alloc] initWithTitle:@"提示" message:@"3G/4G" delegate:self cancelButtonTitle:@"确定" otherButtonTitles:nil, nil] show];                break;            }            default:                break;        }    }];}
