IOS 获取已连接的wifi信息的实现代码

首先需要   #import <SystemConfiguration/CaptiveNetwork.h>

+ (id)fetchSSIDInfo {   NSArray *ifs = (id)CNCopySupportedInterfaces();   NSLog(@"%s: Supported interfaces: %@", __func__, ifs);   id info = nil;   for (NSString *ifnam in ifs) {     info = (id)CNCopyCurrentNetworkInfo((CFStringRef)ifnam);     NSLog(@"%@ => %@", ifnam, info);     if (info && [info count]) { break; }     [info release];   }   [ifs release];   return [info autorelease]; } 

ARC 版本:

+ (id)fetchSSIDInfo {   NSArray *ifs = (__bridge_transfer id)CNCopySupportedInterfaces();   NSLog(@"%s: Supported interfaces: %@", __func__, ifs);   id info = nil;   for (NSString *ifnam in ifs) {     info = (__bridge_transfer id)CNCopyCurrentNetworkInfo((__bridge CFStringRef)ifnam);     NSLog(@"%@ => %@", ifnam, info);     if (info && [info count]) { break; }   }   return info; }
