手机和智能设备匹配Wi-Fi时,我们需要获取手机当前连接的Wi-Fi信息,如SSID,BSSID等。
SSID:全称 Server Set IDentifier, 即Wi-Fi公开的名称
BSSIS:指站点的Mac地址
获取Wi-Fi信息的方法我整理为一个工具类,需要注意的是.h文件必须倒入头文件#import <SystemConfiguration/CaptiveNetwork.h>
.h文件
//SSID
+(NSString *)getDeviceConnectWifiName;
//BSSID
+(NSString *)getDeviceConnectWifiAddress;
//SSIDDATA
+(NSString *)getDeviceConnectWifiData;
.m文件
+(NSString *)getDeviceConnectWifiName{
NSArray *ifs = (__bridge id)CNCopySupportedInterfaces();
id info = nil;
for (NSString *ifnam in ifs) {
info = (__bridge id)CNCopyCurrentNetworkInfo((CFStringRef)CFBridgingRetain(ifnam));
if (info && [info count]) {
break;
}
}
if ([info isKindOfClass:[NSDictionary class]]) {
//获取SSID
return [info objectForKey:@"SSID"];
}
return nil;
}
+(NSString *)getDeviceConnectWifiAddress{
NSArray *ifs = (__bridge id)CNCopySupportedInterfaces();
id info = nil;
for (NSString *ifnam in ifs) {
info = (__bridge id)CNCopyCurrentNetworkInfo((CFStringRef)CFBridgingRetain(ifnam));
if (info && [info count]) {
break;
}
}
if ([info isKindOfClass:[NSDictionary class]]) {
//获取BSSID
return [info objectForKey:@"BSSID"];
}
return nil;
}
+(NSString *)getDeviceConnectWifiData{
NSArray *ifs = (__bridge id)CNCopySupportedInterfaces();
id info = nil;
for (NSString *ifnam in ifs) {
info = (__bridge id)CNCopyCurrentNetworkInfo((CFStringRef)CFBridgingRetain(ifnam));
if (info && [info count]) {
break;
}
}
if ([info isKindOfClass:[NSDictionary class]]) {
//获取SSIDDATA
return [info objectForKey:@"SSIDDATA"];
}
return nil;
}
如此获取Wi-Fi信息基本可以满足要求了。
