iOS获取网络的最新方法(自己试了下没什么问题)

typedef enum { NETWORK_TYPE_NONE= 0, NETWORK_TYPE_WIFI= 1, NETWORK_TYPE_3G= 2, NETWORK_TYPE_2G= 3,

}NETWORK_TYPE;

然后通过获取手机信号栏上面的网络类型的标志

+ (int)dataNetworkTypeFromStatusBar {UIApplication *app = [UIApplicationsharedApplication]; NSArray *subviews = [[[app valueForKey:@"statusBar"] valueForKey:@"foregroundView"] subviews]; NSNumber *dataNetworkItemView = nil;for (id subview in subviews) {if([subview isKindOfClass:[NSClassFromString(@"UIStatusBarDataNetworkItemView") class]]) {dataNetworkItemView = subview;break;} }int netType = NETWORK_TYPE_NONE;NSNumber * num = [dataNetworkItemView valueForKey:@"dataNetworkType"];if (num == nil) {netType = NETWORK_TYPE_NONE;}else{int n = [num intValue];if (n == 0) {netType = NETWORK_TYPE_NONE;}elseif (n == 1){netType = NETWORK_TYPE_2G;}elseif (n == 2){netType = NETWORK_TYPE_3G;}else{netType = NETWORK_TYPE_WIFI;}}return netType;}如果发现问题，请及时告知，谢谢！
