前言
- 阅读本文需要有一定逆向相关基础，否则可能看不懂，哈。
- 虚拟定位、WIFI修改原理是HOOK系统函数，所以并不针对某个APP。
- 本文所讲的是越狱插件，最好有越狱手机，当然你也可以重签名APP来实现HOOK函数。
- 本文纯属逆向知识学习及探讨，请勿用作学习之外的任何用途。
开始
准备
- XCode安装MonkeyDev插件
-
创建LogosTweak项目
image.png - 如果选择要导入PreferenceLoader,要在手机Cydia安装PreferenceLoader插件（雷锋源http://apt.abcydia.com/有）

虚拟定位
- hook函数 - CLLocation的coordinate
// See http://iphonedevwiki.net/index.php/Logos
#if TARGET_OS_SIMULATOR
#error Do not support the simulator, please use the real iPhone Device.
#endif
#import <UIKit/UIKit.h>
#import <CoreLocation/CoreLocation.h>
%hook CLLocation
-(CLLocationCoordinate2D) coordinate
{
CLLocationCoordinate2D location;
//纬度
location.latitude = 26.012345;
//经度
location.longitude = 106.49328;
return location;
}
%end
- 只要修改为你想去的地方的经纬度即可，也可以参考我另一篇文章IOS非越狱虚拟定位（保持定位）查看经纬度怎么写。
- 可以看到，其实就只需要几行代码而已。但是每次都要研究经纬度是多少，再重新安装一次插件，太麻烦。所以我提供一个简易版（就是简单在地图上直接选位置）的选择位置信息控制器ViewController（目标APP需使用的是高德地图）。

当然你还是要导入高德地图API的头文件（随便开个项目，pod高德地图的API再拷贝过来）
最后修改一下xm文件
#import <UIKit/UIKit.h>
#import <CoreLocation/CoreLocation.h>
#import "SelectLocationVct.h"
%hook CLLocation
-(CLLocationCoordinate2D) coordinate
{
return [%c(SelectLocationVct) getSaveLocation];
}
%end
-
来张效果图吧（支持直接点击地图，搜索来确定位置）
image.png
PS：在哪里跳到这个控制器，就个人喜欢了，比如你可以hook某个按钮，或者hook某个控制器然后加个按钮，按钮点击时就跳到这个控制器就行了。
WIFI信息修改
- 使用fishhook钩住系统函数
1、CNCopySupportedInterfaces：获取wifi列表（实际测试只返回当前wifi）
2、CNCopyCurrentNetworkInfo：获取wifi信息
- 相关类
#import <Foundation/Foundation.h>
@interface DataManage : NSObject
+(void) saveDataForObject:(id)value AndKey:(NSString *)key;
+(id) getObjectFromKey:(NSString *)key;
@end
#import "DataManage.h"
@implementation DataManage
#pragma mark - 保存数据和获取数据
+(void) saveDataForObject:(id)value AndKey:(NSString *)key
{
NSUserDefaults *defaluts = [NSUserDefaults standardUserDefaults];
[defaluts setObject:value forKey:key];
[defaluts synchronize];
}
+(id) getObjectFromKey:(NSString *)key
{
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
return [defaults objectForKey:key];
}
@end
- 创建一个实体来保存wifi信息
@interface DVWifiModel : NSObject
// BSSID：路由器的Mac地址
@property (nonatomic, copy) NSString *BSSID;
// SSID:路由器的广播名称
@property (nonatomic, copy) NSString *SSID;
// SSIDDATA:SSID的十六进制
@property (nonatomic, strong) NSData *SSIDDATA;
//CNCopySupportedInterfaces返回的数组里的对象
@property (nonatomic, copy) NSString *ifnam;
+(instancetype) getSaveWifiInfo;
@end
@implementation DVWifiModel
+(instancetype) getSaveWifiInfo
{
NSDictionary *dic = [DataManage getObjectFromKey:@"Wifi_info"];
DVWifiModel *model = [DVWifiModel new];
model.ifnam = dic[@"ifnam"];
model.BSSID = dic[@"BSSID"];
model.SSID = dic[@"SSID"];

- XCode11以上可能遇到的问题
问题一：
An empty identity is not valid when signing a binary for the product type 'Dynamic Library'.
解决方案：
在Building Settings中点击下方的 + 号，选择Add User-Defined Setting，最后添加此变量CODE_SIGNING_ALLOWED = NO
问题二：
building for iOS, but linking in .tbd file (/opt/theos/vendor/lib/CydiaSubstrate.framework/CydiaSubstrate.tbd) built for iOS Simulator, file '/opt/theos/vendor/lib/CydiaSubstrate.framework/CydiaSubstrate.tbd' for architecture arm64.
解决方案：
打开/opt/theos/vendor/lib/CydiaSubstrate.framework/CydiaSubstrate.tbd，删除其中的i386,x86_64架构，保存。
