1、通過監(jiān)聽手機(jī)的statusbar的狀態(tài)還獲取用戶的網(wǎng)絡(luò)狀態(tài)?？梢酝ㄟ^蘋果的審核在Appstore上架。

typedef NS_ENUM(NSUInteger,NetWorkStates) {
    NetworkStatesNone, // 沒有網(wǎng)絡(luò)
    NetworkStates2G, // 2G
    NetworkStates3G, // 3G
    NetworkStates4G, // 4G
    NetworkStatesWIFI // WIFI
};

+ (NetWorkStates)getNetWorkState {
    NSArray *subViews = [[[[UIApplication sharedApplication] valueForKeyPath:@"statusBar"] valueForKeyPath:@"foregroundView"] subviews];
    NetWorkStates state = NetworkStatesNone;
    for (id child in subViews) {
        if ([child isKindOfClass:NSClassFromString(@"UIStatusBarDataNetworkItemView")]) {
            NSInteger netWorkType = [[child valueForKeyPath:@"dataNetworkType"] integerValue];
            switch (netWorkType) {
                case 0:
                    state = NetworkStatesNone;
                    break;
                case 1:
                    state = NetworkStates2G;
                    break;
                case 2:
                    state = NetworkStates3G;
                    break;
                case 3:
                    state = NetworkStates4G;
                    break;
                case 5:
                    state = NetworkStatesWIFI;
                    break;
                default:
                    break;
            }
        }
    }
    return state;
}

2、通過Reachablity監(jiān)聽網(wǎng)絡(luò)狀態(tài) 對用戶設(shè)備的網(wǎng)絡(luò)狀態(tài)進(jìn)行實(shí)時監(jiān)控。

- (void)checkNetworkStates
{
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(networkChange) name:kReachabilityChangedNotification object:nil];
    _reacha = [Reachability reachabilityWithHostName:@"http://www.baidu.com"];
    [_reacha startNotifier];
}

- (void)networkChange {
    NetworkStatus status = [_reacha currentReachabilityStatus];
    
    switch (status) {
        case NotReachable:
            break;
        case ReachableViaWWAN:
            break;
        case ReachableViaWiFi:
            break;
        default:
            break;
    }
}

NewWorkStatus有三種狀態(tài):

typedef NS_ENUM(NSInteger, NetworkStatus) {
    // Apple NetworkStatus Compatible Names.
    NotReachable = 0,  //沒有網(wǎng)絡(luò)
    ReachableViaWiFi = 2, //wifi
    ReachableViaWWAN = 1 //運(yùn)營商網(wǎng)絡(luò)
};
