IOS 獲取已連接的wifi信息的實現代碼
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; } 以上就是IOS 獲取已連接的wifi信息的實例，如有疑問請留言或者到本站社區交流討論，感謝閱讀，希望能幫助到大家，謝謝大家對本站的支持！
