适用于iOS8的Wifi扫描仪

Question

如何在iOS8中找到Wifi信号强度（RSSI）？

我知道Apple限制应用程序直接访问Wi-Fi数据/ API，并且不会在AppStore中接受。我找到了一个名为Stumbler的私有API，它本应该做同样的事情。这是它的链接。 Accessing & Using the MobileWiFi.framework

networks = [[NSMutableDictionary alloc] init];

void* library = dlopen("/System/Library/SystemConfiguration/IPConfiguration.bundle/IPConfiguration", RTLD_LAZY);

int (*apple80211Open)(void*) = (int(*)(void*))dlsym(library, "Apple80211Open");

int (*apple80211Bind)(void*, NSString*) = (int(*)(void*, NSString*))dlsym(library, "Apple80211BindToInterface");
apple80211Close = (int(*)(void*))dlsym(library, "Apple80211Close");
apple80211Scan= (int(*)(void*, NSArray**, void*))dlsym(library, "Apple80211Scan");

void *airport = NULL;
apple80211Open(&airport);

apple80211Bind(airport, @"en0");

NSArray* arrNetworks = nil;
apple80211Scan(airport, &arrNetworks, (__bridge void *)(networks));

//"networks" is an array of NSDictionary objects for all the visible Wi-Fi networks

apple80211Close(airport);
dlclose(library);

不知何故，这在iOS8中无效。任何人都知道如何让这个工作？谢谢你的帮助!!
