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; }
