以下是您可以參考的代碼。

- (NSDictionary *)fetchSSIDInfo 
{ 

NSArray *interfaceNames = CFBridgingRelease(CNCopySupportedInterfaces()); 
NSLog(@"%s: Supported interfaces: %@", __func__, interfaceNames); 

NSDictionary *SSIDInfo; 
for (NSString *interfaceName in interfaceNames) { 
    SSIDInfo = CFBridgingRelease(
     CNCopyCurrentNetworkInfo((__bridge CFStringRef)interfaceName)); 
    NSLog(@"%s: %@ => %@", __func__, interfaceName, SSIDInfo); 

    BOOL isNotEmpty = (SSIDInfo.count > 0); 
    if (isNotEmpty) { 
     break; 
    } 
} 
return SSIDInfo; 

}
