怎样在ios上获取wifi的相关信息？
rt 怎样获取设备的wifi信息，如信号强弱，热点名称等 --------------------编程问答-------------------- 求出一般式，然后解方程。C/C++ code
int
Calc_Two_Line_Point( double a1, double b1, double c1, double a2, double b2, double c2, OUT double *x, OUT double *y )
{
double xx, yy;
double e;
e ……

在ios扫描公共区域内wifi信息中，写了实现wifi扫描的一种方法，但是那种方法扫描出来的wifi信息不全，下面是扫描全部wifi信息的实现方法：
#import <CoreFoundation/CoreFoundation.h>
#import <Foundation/NSTimer.h>
#import <Foundation/Foundation.h>
#include <dlfcn.h>
#include <ifaddrs.h>
#include <arpa/inet.h>

int (*close)(void *);
int (*associate)(void *, NSDictionary*, NSString*);

//int (*open)(void *);

添加到项目中即可。
--------------------编程问答--------------------
项目要上线的，不越越能行吗，我没有越狱机器，我要做的也不是越狱项目
--------------------编程问答--------------------
顶一个哈。。。很不错
--------------------编程问答--------------------
.m 文件的 28- 29 行 那边
for (x = 0; x < MAC_LEN; x++)
longmac |= (uint64_t) bs_in[x] << ((MAC_LEN - x – 1) * 8);
这个 报错了 Expected ')'
请问怎弄弄啊
--------------------编程问答--------------------
MSNetworksManager *manager = [MSNetworksManager sharedNetworksManager];NSString *add = [manager localIPAddress];
NSLog(@"add:%@", add);
直接 Crash了 么。。。
error: address doesn't contain a section that points to a section in a object file
补充：移动开发 , iPhone
