判断iPhone的WiFi是否打开的两种方法

#import <ifaddrs.h>#import <net/if.h>#import <SystemConfiguration/CaptiveNetwork.h>- (BOOL) isWiFiEnabled {NSCountedSet * cset = [NSCountedSet new];struct ifaddrs *interfaces;if( ! getifaddrs(&interfaces) ) {for( struct ifaddrs *interface = interfaces; interface; interface = interface->ifa_next) {if ( (interface->ifa_flags & IFF_UP) == IFF_UP ) {[cset addObject:[NSString stringWithUTF8String:interface->ifa_name]];}}}return [cset countForObject:@"awdl0"] > 1 ? YES : NO;}

- (BOOL)isWiFiConnected {UIApplication *app = [UIApplication sharedApplication];NSArray *children = [[[app valueForKeyPath:@"statusBar"] valueForKeyPath:@"foregroundView"] subviews];//获得到网络返回码for (id child in children) {if ([child isKindOfClass:NSClassFromString(@"UIStatusBarDataNetworkItemView")]) {int netType = [[child valueForKeyPath:@"dataNetworkType"] intValue];NSLog(@"type:%@",@(netType));if (netType == 1) {NSLog(@"2G");return NO;}else if (netType == 2) {NSLog(@"3G");return NO;}else if (netType == 3) {NSLog(@"4G");return NO;}else if (netType == 5){NSLog(@"Wifi");return YES;}// 1，2，3，5 分别对应的网络状态是2G、3G、4G及WIFI。(需要判断当前网络类型写个switch 判断就OK)}}NSLog(@"not open network or no net work");return NO;}
