iOS浏览器小说去广告分析与Hook技术文档<\/h1>

1. 背景与目标<\/h2>
本文档基于某iOS浏览器的小说阅读功能广告去除需求，分析其广告展示机制并实现Hook拦截。仅供学习研究使用，请支持正版内容。<\/p>

2. 环境准备<\/h2>

2.1 必要工具<\/h3>

iOS逆向工具链：

Frida (动态分析)<\/li>
Theos (Hook开发)<\/li>
IDA Pro\/Ghidra (静态分析)<\/li>
class-dump (类信息导出)<\/li>

Cycript (运行时分析)<\/li> <\/ul> <\/li> <\/ul>

2.2 目标应用<\/h3>

某iOS浏览器应用（版本需具体分析）<\/li>

需获取脱壳后的可执行文件<\/li> <\/ul>

3. 静态分析<\/h2>

3.1 二进制分析<\/h3>

使用otool检查二进制架构：<\/p>

otool -hv target_binary
<\/span><\/span><\/code><\/pre><\/li>

使用class-dump导出头文件：<\/p>
class-dump -H target_binary -o headers\/
<\/span><\/span><\/code><\/pre><\/li>
<\/ol>
3.2 关键类识别<\/h3>
通过分析导出的头文件，寻找与广告相关的类，常见命名模式：<\/p>

AD*<\/code> (如ADManager, ADViewController)<\/li>
*Ad*<\/code> (如BannerAd, NativeAd)<\/li>
*Advertisement*<\/code><\/li>
*Splash*<\/code> (开屏广告)<\/li>
<\/ul>
4. 动态分析<\/h2>
4.1 Frida动态跟踪<\/h3>


枚举所有类：<\/p>
ObjC<\/span>.enumerateLoadedClasses<\/span>({
<\/span><\/span>  onMatch<\/span>:<\/span> function<\/span>(className<\/span>) {
<\/span><\/span>    console<\/span>.log<\/span>(className<\/span>);
<\/span><\/span>  },
<\/span><\/span>  onComplete<\/span>:<\/span> function<\/span>() {}
<\/span><\/span>});
<\/span><\/span><\/code><\/pre><\/li>

跟踪广告相关方法调用：<\/p>
Interceptor<\/span>.attach<\/span>(ObjC<\/span>.classes<\/span>.ADManager<\/span>["- loadAd"<\/span>].implementation<\/span>, {
<\/span><\/span>  onEnter<\/span>:<\/span> function<\/span>(args<\/span>) {
<\/span><\/span>    console<\/span>.log<\/span>("ADManager loadAd called"<\/span>);
<\/span><\/span>  }
<\/span><\/span>});
<\/span><\/span><\/code><\/pre><\/li>
<\/ol>
4.2 Cycript交互分析<\/h3>


获取当前视图控制器：<\/p>
UIApp<\/span>.keyWindow<\/span>.rootViewController<\/span>
<\/span><\/span><\/code><\/pre><\/li>

遍历视图层次查找广告视图：<\/p>
[[[UIApp<\/span> keyWindow<\/span>] rootViewController<\/span>] _printDescription<\/span>]
<\/span><\/span><\/code><\/pre><\/li>
<\/ol>
5. Hook实现<\/h2>
5.1 Theos Hook方案<\/h3>
创建Tweak项目，编写Hook代码：<\/p>
%<\/span>hook ADManager
<\/span><\/span>
<\/span><\/span>-<\/span> (void<\/span>)loadAd {
<\/span><\/span>   NSLog(@"广告加载被拦截"<\/span>);
<\/span><\/span>   \/\/ return %orig; \/\/ 可选是否调用原始实现
<\/span><\/span><\/span><\/span>}
<\/span><\/span>
<\/span><\/span>%<\/span>end
<\/span><\/span><\/code><\/pre>5.2 关键Hook点<\/h3>


广告加载拦截：<\/p>
%<\/span>hook ADService
<\/span><\/span>-<\/span> (void<\/span>)requestAdWithCompletion:(id<\/span>)completion {
<\/span><\/span>    NSLog(@"广告请求被拦截"<\/span>);
<\/span><\/span>    \/\/ 直接返回空数据或模拟成功回调
<\/span><\/span><\/span><\/span>}
<\/span><\/span>%<\/span>end
<\/span><\/span><\/code><\/pre><\/li>

广告视图显示拦截：<\/p>
%<\/span>hook ADBannerView
<\/span><\/span>-<\/span> (void<\/span>)displayAd {
<\/span><\/span>    NSLog(@"广告显示被拦截"<\/span>);
<\/span><\/span>    [self removeFromSuperview];
<\/span><\/span>}
<\/span><\/span>%<\/span>end
<\/span><\/span><\/code><\/pre><\/li>

开屏广告跳过：<\/p>
%<\/span>hook SplashViewController
<\/span><\/span>-<\/span> (void<\/span>)viewDidAppear:(BOOL<\/span>)animated {
<\/span><\/span>    [self dismissViewControllerAnimated:NO completion:nil];
<\/span><\/span>}
<\/span><\/span>%<\/span>end
<\/span><\/span><\/code><\/pre><\/li>
<\/ol>
6. 进阶技巧<\/h2>
6.1 广告数据源替换<\/h3>
%<\/span>hook NovelReaderDataSource
<\/span><\/span>-<\/span> (NSArray *<\/span>)chapterContents {
<\/span><\/span>    NSArray *<\/span>orig =<\/span> %<\/span>orig;
<\/span><\/span>    return<\/span> [orig filteredArrayUsingPredicate:
<\/span><\/span>           [NSPredicate predicateWithBlock:^<\/span>BOOL<\/span>(id<\/span> item, NSDictionary *<\/span>bindings) {
<\/span><\/span>        return<\/span> ];
<\/span><\/span>    }]];
<\/span><\/span>}
<\/span><\/span>%<\/span>end
<\/span><\/span><\/code><\/pre>6.2 网络请求拦截<\/h3>
%<\/span>hook NSURLSession
<\/span><\/span>-<\/span> (void<\/span>)dataTaskWithRequest:(NSURLRequest *<\/span>)request 
<\/span><\/span>          completionHandler:(void<\/span> (^<\/span>)(NSData *<\/span>, NSURLResponse *<\/span>, NSError *<\/span>))completion {
<\/span><\/span>    if<\/span> ([request.URL.host containsString:@"adserver"<\/span>]) {
<\/span><\/span>        completion(nil, nil, [NSError errorWithDomain:@"ADBlock"<\/span> code:500<\/span> userInfo:nil]);
<\/span><\/span>        return<\/span>;
<\/span><\/span>    }
<\/span><\/span>    %<\/span>orig;
<\/span><\/span>}
<\/span><\/span>%<\/span>end
<\/span><\/span><\/code><\/pre>7. 测试与验证<\/h2>


安装测试Tweak：<\/p>
make package install
<\/span><\/span><\/code><\/pre><\/li>

验证方法：<\/p>

检查控制台日志<\/li>
使用Reveal检查视图层次<\/li>
网络抓包验证广告请求<\/li>
<\/ul>
<\/li>
<\/ol>
8. 对抗与反检测<\/h2>


随机化Hook点：<\/p>
static<\/span> __attribute__<\/span>((constructor)) void<\/span> _logosLocalInit() {
<\/span><\/span>  @autoreleasepool<\/span> {
<\/span><\/span>    \/\/ 动态检测类是否存在再Hook
<\/span><\/span><\/span><\/span>    if<\/span> (objc_getClass("ADManager"<\/span>)) {
<\/span><\/span>        %<\/span>init(ADManagerHook);
<\/span><\/span>    }
<\/span><\/span>  }
<\/span><\/span>}
<\/span><\/span><\/code><\/pre><\/li>

反反Hook检测：<\/p>
%<\/span>hook ADSDK
<\/span><\/span>-<\/span> (BOOL<\/span>)isDebugging {
<\/span><\/span>    return<\/span> NO;
<\/span><\/span>}
<\/span><\/span>%<\/span>end
<\/span><\/span><\/code><\/pre><\/li>
<\/ol>
9. 注意事项<\/h2>

法律风险：仅用于学习研究，不得用于商业用途<\/li>
稳定性：Hook可能影响应用稳定性，需充分测试<\/li>
更新维护：应用更新后需重新分析Hook点<\/li>
<\/ol>
10. 参考资料<\/h2>

iOS逆向工程书籍与文档<\/li>
Frida官方文档<\/li>
Theos开发指南<\/li>
ARM64汇编手册<\/li>
<\/ol>

本技术文档提供了从分析到实现的完整流程，实际应用中需根据具体目标应用调整Hook点和实现方式。建议在越狱设备或模拟器中进行测试，避免影响主设备使用。<\/p>
