iOS 中如何判断当前是2G/3G/4G/5G/WiFi
iOS 中如何判断当前是2G/3G/4G/5G/WiFi

一般有两种办法来实现:

1.使用AFNetWorking:
2.根据状态栏的显示来判断.

但是在iphonex上这个方法报错了(具体原因可以参见另外一篇文章,感谢,非常详细) 文章

- (BOOL)isWWAN {
    
    if (iPhoneX) {
        //这是第一种办法:这里没有必要再去判断是不是iPhoneX,直接使用AFN的判断方法就好了
        if ([AFNetworkReachabilityManager sharedManager].networkReachabilityStatus == AFNetworkReachabilityStatusReachableViaWiFi) {
            return YES;
        }else{
            return NO;
        }
    }else{
        UIApplication *app = [UIApplication sharedApplication];
        NSArray *children = [[[app valueForKeyPath:@"statusBar"]valueForKeyPath:@"foregroundView"]subviews];
        int netType = 0;
        for (id child in children) {
            if ([child isKindOfClass:NSClassFromString(@"UIStatusBarDataNetworkItemView")]) {
                // 0: 无网络  1:2G 2:3G 3:4G  5:WIFI
                netType = [[child valueForKeyPath:@"dataNetworkType"]intValue];
            }
        }
        BOOL WWAN = NO;
        if (netType == 1 || netType == 2 || netType == 3) {
            
            WWAN =  YES;
        }
        return WWAN;
    }

}

还是打印一下现在的statusBar 的subViews

    NSLog(@"%@",[[app valueForKeyPath:@"statusBar"] subviews]);

结果为:

可以看出iphonex上的标识为<_UIStatusBarWifiItem: 0x604000441b90: identifier=_UIStatusBarWifiItem>

这个identifier为_UIStatusBarWifiItem ,也可以通过这个来判断
