Question

我需要在Objective C中运行一个程序。我找到了获取wifi信号强度的代码。

我没有收到mobilewifi.h文件？哪个可用。我用Google搜索了一下。

此外，我不知道我应该在这个项目中保留这个文件？在哪个.m文件？ App Delegate ??

代码是：

#include <math.h>
#include <MobileWiFi.h>

WiFiManagerRef manager = WiFiManagerClientCreate(kCFAllocatorDefault, 0);
CFArrayRef devices = WiFiManagerClientCopyDevices(_manager);

WiFiDeviceClientRef client = (WiFiDeviceClientRef)CFArrayGetValueAtIndex(devices, 0);
CFDictionaryRef data = (CFDictionaryRef)WiFiDeviceClientCopyProperty(_device, CFSTR("RSSI"));
CFNumberRef scaled = (CFNumberRef)WiFiDeviceClientCopyProperty(_device, kWiFiScaledRSSIKey);

CFNumberRef RSSI = (CFNumberRef)CFDictionaryGetValue(data, CFSTR("RSSI_CTL_AGR"));

int raw;
CFNumberGetValue(RSSI, kCFNumberIntType, &raw);

float strength;
CFNumberGetValue(scaled, kCFNumberFloatType, &strength);
CFRelease(scaled);

strength *= -1;

// Apple uses -3.0.
int bars = (int)ceilf(strength * -3.0f);
bars = MAX(1, MIN(bars, 3));


printf("WiFi signal strength: %d dBm\n\t Bars: %d\n", raw,  bars);

CFRelease(data);
CFRelease(scaled);
CFRelease(devices);
CFRelease(manager);
