IOS 获取已连接的wifi信息的实现代码

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;
}
