[英]Theos: How to hook a method with a block argument? (CDUnknownBlockType)
%hook HTTPClient
- (CDUnknownBlockType)completionForSuccess:(CDUnknownBlockType)arg1 {
}
%end
I am wondering what to place in place of CDUnknownBlockType
here (generated from class-dump). 我想知道在这里放置什么代替
CDUnknownBlockType
(从类转储生成)。 I do not know the arguments to the block so I cannot put the exact signature. 我不知道块的参数所以我不能把确切的签名。 Is it possible to instead use
MSHookMessage
with a generic pointer as the argument? 是否可以使用带有通用指针的
MSHookMessage
作为参数? A generic void *
pointer did not work for me here as the message does not match. 一般的
void *
指针在我这里不起作用,因为消息不匹配。
Is there a way to get the block's signature? 有没有办法获得该块的签名?
You can replace the CDUnknownBlockType
with id
. 您可以使用
id
替换CDUnknownBlockType
。 It's as simple as that. 就这么简单。
