## 说明
* 本项目改编于[Naituw IPAPatch](https://github.com/Naituw/IPAPatch)，站在巨人的肩膀上学习
* 本工程已集成Reavel 20的framework，直接运行即可添加
* 本工程集成了FLEX.framework，运行后即可动态调试
* 本工程集成了Dobby框架，使用方法见下方（Dobby默认不启用，需自行开启）
* 本工程集成了frida-gadget，基于frida 15.0.15版本重新编译，解决了线程阻塞问题，可以在非越狱手机上使用frida调试APP
* 本工程集成了常见的反调试方法的绕过，如ptrace，syscall，sysctl，isatty等（IPAPatchBypassAntiDebugging.m）
* 修复恢复符号表功能， **目前只能恢复arm64的machO文件**，如果是Fat格式machO需要自己先瘦身
* 本工程集成了svc 0x80的反调试方法的绕过（IPAPatchBypassAntiDebugging.m），代码来自于[xia0LLDB](https://github.com/4ch12dy/xia0LLDB)，未经完全测试，可能会有[页边界问题](https://bbs.pediy.com/thread-254385.htm)
* 本工程利用OC的runtime机制，添加了替换任意方法(包括代理方法)的函数（Tools.m）
* 使用方法：将砸壳后的ipa包重命名为app.ipa，然后放入Assets文件夹下，打开IPAPatch工程直接运行即可，运行前请选好证书，改好bundleID
* 代替class-dump的新方案[dsdump](https://github.com/paradiseduo/dsdump)
* 在装有M1芯片的Mac上脱壳的方案[appdecrypt](https://github.com/paradiseduo/appdecrypt)
## Dobby使用
首先在option.plist中将Dobby的选项打开：
以hook sum方法为例，sum为写在app.ipa中的一个C语言函数：
```
int sum(int a,int b){
return a + b;
}
```
在IPAPatchEntry.m内
```
#import //为了使用objc_msgSend
int (*originSum)(int a, int b); // 保留原始的方法实现的指针地址
//新函数
int hookSum(int a,int b){
return a * b;
}
+ (void)load {
static uintptr_t sumOffset = 0x100005724; // sum函数的偏移地址可以通过IDA去查看
uintptr_t mainASLR = _dyld_get_image_vmaddr_slide(0); // 获取主程序的ASLR，因为sum函数在主程序的image中，因此这里的参数是0
uintptr_t sumAddress = mainASLR + sumOffset;
// 构造SEL，dobbyHookWith:replace:origin:是OC封装过得DobbyHook(void *address, void *replace_call, void **origin_call)
SEL sel = NSSelectorFromString(@"dobbyHookWith:replace:origin:");
// 通过反射寻找DobbyOC类，并调用SEL
((void (*) (id, SEL, void *, void *, void **)) objc_msgSend) (NSClassFromString(@"DobbyOC"), sel, (void *)sumAddress, hookSum, (void *)&originSum);
}
```

## Features
**IPAPatch** includes an template Xcode project, that provides following features:
- **Build & Run third-party ipa with your code injected**
You can run your own code inside ipa file as a dynamic library. So you can change behavior of that app by utilizing Objective-C runtime.
> *Presented an custom alert in Youtube app*
>
> 
- **Step-by-step Debugging with lldb**
You can debug third-party apps like your own. For example:
- Step-by-Step debug your code inside other app
- Set Breakpoints
- Print objects in Xcode console with lldb
> *Debugging Youtube with Xcode*
>
> 
- **Link external frameworks**
By linking existing frameworks, you can integrate third-party services to apps very easily, such as Reveal.
> *Inspect Youtube by linking RevealServer.framework*
>
> 
- **Generate distributable .ipa files**
You can distribute your patch/work to your friends very easily, with IPAPatch generated modified version of .ipa files
> *Modified version of Facebook.ipa created by IPAPatch*
>
> 
## Instructions
1. **Clone or Download This Project**
Download this project to your local disk
2. **Prepare Decrypted IPA File**
The IPA file you use need to be decrypted, you can get a decrypted ipa from a jailbroken device or download it directly from an ipa download site, such as http://www.iphonecake.com
3. **Replace Placeholder IPA**
Replace the IPA file located at `IPAPatch/Assets/app.ipa` with yours, this is a placeholder file. The filename should remain `app.ipa` after replacing.
4. **Place External Resources/Frameworks (Optional)**
Follow types of external file are supported:
- **Frameworks**:
- External frameworks can be placed at `IPAPatch/Assets/Frameworks` folder.
- Frameworks will be linked automatically.
- For example `IPAPatch/Assets/Frameworks/RevealServer.framework`
- **Dynamic Libraries**:
- External dynamic libraries can be placed at `IPAPatch/Assets/Dylibs` folder.
- Libraries will be linked automatically
- **Resources/Bundles**:
- Other resources or bundles can be placed at `IPAPatch/Assets/Resources`
- Resources will be copied directly to the main bundle of original app
5. **Configure Build Settings**
- Open `IPAPatch.xcodeproj`
- In the Project Editor, Select Target `IPAPatch-DummyApp`
- `Display Name` defaults to "💊", this is used as prefix of the final display name.
- Change `Bundle Identifier` to match your provisioning profiles
- Fix signing issues if any.
6. **Configure IPPatch Options**
- You can config IPAPatch's behavior with `Tools/options.plist`
| Name | Description | Default |
| --- | --- | --- |
| RESTORE_SYMBOLS | When `YES`, IPAPatch will try to restore symbol table from Mach-O for debugging propose (with tools from https://github.com/tobefuturer/restore-symbol, also thanks to @henrayluo and @dannion) | NO |
| CREATE_IPA_FILE | When `YES`, IPAPatch will generate a ipa file on each build. Genrated file is located at `SRCROOT/Product` | NO |
| IGNORE_UI_SUPPORTED_DEVICES | When `YES`, IPAPatch will delete `UISupportedDevices` from source app's `Info.plist` | NO |
| REMOVE_WATCHPLACEHOLDER | When `YES`, IPAPatch will remove `com.apple.WatchPlaceholder` folder from source app's bundle | YES |
| USE_ORIGINAL_ENTITLEMENTS | When `YES`, IPAPatch will use source app's entitlements to resign, you need to make sure your Provisioning Profile matches the entitlements, or you need to disable `AMFI` on target device | NO |
7. **Code Your Patch**
The entry is at `+[IPAPatchEntry load]`, you can write code start from here. To change apps' behavior, You may need to use some method swizzling library, such as [steipete/Aspects](https://github.com/steipete/Aspects).
8. **Build and Run**
Select a real device, and hit the "Run" button at the top-left corner of Xcode. The code your wrote and external frameworks you placed will inject to the ipa file automatically.
## Example
I created some demo project, which shows you how to use `IPAPatch`:
- Reveal + Youtube:
- https://github.com/Naituw/IPAPatch/releases/tag/1.0
- Cycript + Youtube (Idea from @phpmaple):
- https://github.com/Naituw/IPAPatch/releases/tag/1.0.1
## FAQ
- Q: Library not loaded with reason: `mach-o, but wrong architecture` ?
- A: Try set `IPAPatch` target's `Valid Architectures` to match your ipa binary's architecture.
- Q: process launch failed: Unspecified (Disabled) ?
- A: The ipa file use with IPAPatch must be decrypted, See step.2 of Instructions.
- Q: dyld: Symbol not found: XXX, Referenced from: XXX, Expected in: XXX/libswiftXXX.dylib
- The swift version the framework you injecting use, is incompatible with the version of your Xcode
