使用私有API读取WiFi RSSI值

swift

我正在开发不需要在App Store上的东西，因此使用私有API满足我的需求没有问题，我正在尝试使用MobileWiFi. framework to read the RSSI value for the wireless network the phone is currently connected to. I've included thehttps://github.com/Cykey/ios-reversed -headers / tree /

MobileWiFi`标头，并使用桥接标头将它们包括在我的swift项目中，并编写了如下代码。请原谅，我是新手。

import SystemConfiguration.CaptiveNetwork
typealias _WiFiManagerClientCreate = @convention(c) (CFAllocator, CInt) -> UnsafeRawPointer
typealias _WiFiManagerClientCopyDevices = @convention(c) (UnsafeRawPointer) -> CFArray
typealias _WiFiDeviceClientCopyProperty = @convention(c) (UnsafeRawPointer, CFString) -> CFPropertyList

if let libHandle = dlopen (Paths.ipConfiguration, RTLD_LAZY) {
        result = libHandle.debugDescription

        let _createManagerPtr = dlsym(libHandle, "WiFiManagerClientCreate")
        let _clientCopyDevicesPtr = dlsym(libHandle, "WiFiManagerClientCopyDevices")
        let _clientCopyPropertyPtr = dlsym(libHandle, "WiFiDeviceClientCopyProperty")

        if (_createManagerPtr != nil) && (_clientCopyDevicesPtr != nil) && (_clientCopyPropertyPtr != nil) {
            let _createManager = unsafeBitCast(_createManagerPtr, to: _WiFiManagerClientCreate.self)
            let _clientCopyDevices = unsafeBitCast(_clientCopyDevicesPtr, to: _WiFiManagerClientCopyDevices.self)
            let _clientCopyProperty = unsafeBitCast(_clientCopyPropertyPtr, to: _WiFiDeviceClientCopyProperty.self)

            let manager = _createManager(kCFAllocatorDefault, 0)
            let devices = _clientCopyDevices(manager)
            let client = CFArrayGetValueAtIndex(devices, 0)

            let data = _clientCopyProperty(client!, "RSSI" as CFString)
            let rssi = CFDictionaryGetValue(data as! CFDictionary, "RSSI_CTL_AGR")

            NSLog("RSSI: \(rssi)")
        }

        dlclose(libHandle)
    }

这产生一个错误 fatal error: unexpectedly found nil while unwrapping an Optional value which stems from trying to call _createManager

我最终使用了这种解决方法：

+ (int) wifiStrength {
UIApplication *app = [UIApplication sharedApplication];
NSArray *subviews = [[[app valueForKey:@"statusBar"] valueForKey:@"foregroundView"] subviews];
NSString *dataNetworkItemView = nil;

for (id subview in subviews) {
    if([subview isKindOfClass:[NSClassFromString(@"UIStatusBarDataNetworkItemView") class]]) {
        dataNetworkItemView = subview;
        break;
    }
}

return[[dataNetworkItemView valueForKey:@"wifiStrengthRaw"] intValue];
}
