列出/扫描可用的WiFis iPhone

Question

我正在寻找一种在iPhone App中展示可用WiFis的方法.到目前为止,我的研究结果如下:

• 实现(编辑)此类功能的应用程序已从AppStore中删除(意味着您无法通过AppStore部署应用程序,这对我来说很好)
• Apple隐藏了私有框架中扫描所需的功能,您无法找到关于"如何使用"的任何解释/注释/示例
• http://code.google.com/p/iphone-wireless似乎最有前途.无论如何,我无法弄清楚如何在我的代码中包含已交付的源,以便它在设备上运行

甚至提到的改编件:http://code.google.com/p/iphone-wireless/issues/detail？id = 26也没有得到我想要的结果.最进步的结果是

dlopen错误:dlopen(/System/Library/SystemConfiguration/Aeropuerto.bundle/Aeropuerto,1):未找到图像失败:__ Apple80211Associate

在设备上启动应用程序后的消息(iPhone 3GS; iOS 3.1.3).

使用了导致错误的源代码:

NSMutableDictionary *networks;
bool scanning;
void *libHandle;
void *airportHandle;
int (*open)(void *);
int (*bind)(void *, NSString *);
int (*close)(void *);
int (*scan)(void *, NSArray **, void *);

networks = [[NSMutableDictionary alloc] init];
// libHandle = dlopen("/System/Library/Frameworks/Preferences.framework/Preferences", RTLD_LAZY);
// libHandle = dlopen("/System/Library/PrivateFrameworks/Apple80211.framework/Preferences", RTLD_LAZY);
libHandle = dlopen("/System/Library/SystemConfiguration/WiFiManager.bundle/WiFiManager", RTLD_LAZY);

open = dlsym(libHandle, "Apple80211Open");
bind = dlsym(libHandle, "Apple80211BindToInterface");
close = dlsym(libHandle, "Apple80211Close");
scan = dlsym(libHandle, "Apple80211Scan");

open(&airportHandle);
bind(airportHandle, @"en0");

NSLog(@"Scanning...");
scanning = true;
NSArray *scan_networks;
NSDictionary *parameters = [[NSDictionary alloc] init];
scan(airportHandle, &scan_networks, parameters);
bool changed;
for (int i = 0; i < [scan_networks count]; i++) {
    if([networks objectForKey:[[scan_networks objectAtIndex: i] objectForKey:@"BSSID"]] != nil 
       && ![[networks objectForKey:[[scan_networks objectAtIndex: i] objectForKey:@"BSSID"]] isEqualToDictionary:[scan_networks objectAtIndex: i]])
        changed = true;
    [networks setObject:[scan_networks objectAtIndex: i] forKey:[[scan_networks objectAtIndex: i] objectForKey:@"BSSID"]];
}
if(changed) {
    NSLog(@"NetworksUpdated");
}
scanning = false;
NSLog(@"Scan Finished...");
NSLog(@"Found %i networks: %@", [networks count], networks);

即使尝试其中一个注释行,它也不起作用:程序收到了EXC_BAD_ACCESS和几个

警告:check_safe_call:无法恢复当前帧

警告:无法恢复以前选择的帧.

我正在搜索的是如何在我的项目中包含iphone-wireless以及如何修改给定代码的提示？另一种方法是如何在您的环境中扫描WiFis.

如果有人可以提供帮助,那会很好.

Answer 1

有关iphone无线的使用示例,您可以查看以下帖子,

http://blog.guvenergokce.com/iphone-wireless-scanner-ios5/

在那里,您还可以找到使用XCode 4.2开发的示例项目.

正如您所提到的,这仅适用于研究或私人项目,我们无法分发.

祝好运,

Answer 2

路径在 3.X 及更高版本中已更改，从：

/System/Library/SystemConfiguration/Aeropuerto.bundle/Aeropuerto

到：

/System/Library/SystemConfiguration/IPConfiguration.bundle/IPConfifuration
