iPhone/iPad 应用程序代码混淆 - 有可能吗?值得? [英] iPhone/iPad App Code Obfuscation - Is it Possible? Worth it?
问题描述
我已经研究了很多，包括 SO，以及到处都是 google-ing，但我似乎无法找到关于 iPhone/iPad 应用程序代码混淆的直接答案目标-C.
I've researched quite a bit, both on SO, as well google-ing all over the place, but I can't seem to find a straight-forward answer in regards to code obfuscation for iPhone/iPad apps written in Objective-C.
我的问题是:
- 有没有办法做到这一点?如果是这样，怎么办?
- 值得吗?
- 在向 Apple 提交应用程序时，Apple 是否允许这样做或对此存在问题?
推荐答案
Objective-C 似乎没有代码混淆器.但让我们暂时假设一个确实存在.
There doesn't seem to a code obfuscator for Objective-C. But let's assume for a moment that one does exist.
Apple 可能不会拒绝混淆的应用程序，只要它不会崩溃.主要问题是:混淆的重点是什么?通常，您希望混淆代码以保护您的知识，例如，如果您的程序使用复制保护，您想让潜在的破解者更难，或者如果您使用一些高级算法，您不希望商业竞争对手成为能够反编译它.
Apple will probably not reject an obfuscated app as long as it doesn't crash. The main question is: what is the point of obfuscation ? Normally, you want to obfuscate code to protect your knowledge, for example if your program uses a copy protection you want to make it harder for a potential cracker or if you're using some advanced algorithm you don't want the business competitors to be able to decompile it.
复制保护已在 iOS 上得到处理.虽然通过越狱可以复制和运行普通应用程序，但我认为这样做的实际用户数量相当低(至少比 PC 和 Mac 等常规"计算机低很多).您认为盗版是一个需要混淆的大问题吗?
The copy protection is already been taken care of on iOS. Although through jailbreaking a normal app can be copied and run, I'd say the actual number of users who do this is fairly low (at least a lot lower than on "regular" computers like PC and Mac). Do you expect piracy such a big problem that you need to obfuscate ?
如果您确实有重要的知识需要保护，那么混淆可能是值得的.混淆有它的缺点:你不能再调试你的混淆应用程序.崩溃报告将毫无用处.
If you do have important knowledge to protect then obfuscation might be worthwhile. Obfuscation has its downsides: you can't debug your obfuscated app any more. Crash reports will be useless.
您可能还想阅读文章混淆可可.
回到似乎没有混淆器的事实:你可以做的是这个技巧:假设你有一个这样的标题:
Back to the fact there doesn't seem to be an obfuscator: What you can do is this trick: say you have a header like this:
@interface MyClass : NSObject {
}
- (void)myMethod;
你可以像这样进行廉价的混淆:
You could do a cheap obfuscation like this:
#ifndef DEBUG
#define MyClass aqwe
#define myMethod oikl
#endif
@interface MyClass : NSObject {
}
- (void)myMethod;
这样您仍然可以在源代码中使用有意义的符号，但是编译器在不编译用于调试时会将其变成垃圾".
This way you can still use meaningful symbols in your source, but the compiler would turn it into "garbage" when not compiling for debugging.
