Tutorial Hooking method(s) with a dot class in Flex to Tweak.xm

[Amuyea 87.4k iPhone 7 Plus 14.3]

In some of the apps, when you try to hack a class with a  "." or a dot function.

 

Flex to Tweak.xm Tutorial:

https://iosgods.com/topic/904-tutorialvideo-hack-games-with-flex-and-convert-it-to-deb-tweak/

There are more on this kind, check them out!

 

Let's get started!

In Flex, it would work fine, but when you try to convert flex to tweak.xm and make package.

It gives you an error, "error: cannot use dot operator on a type"

*I don't hack this application, it's an example to solve this issue*

 

Using the tutorial, flex to tweak.xm.

I get this,

%hook OkCupid.OKMessage
-(BOOL)read {
return TRUE;
}
%end

It will throw me an error after "make package" command in terminal.

 

A way around the error template:

%hook AnyRandomNameHere
- (id)description {
    return %orig();
}
%end

%ctor {
    %init(AnyRandomNameHere = objc_getClass("ClassNameWithADotHere"));
}

 

Now, I will convert it in this way.

Final Code:

%hook CupidMess
-(BOOL)read {
return TRUE;
}
%end

%ctor {
    %init(CupidMess = objc_getClass("OkCupid.OKMessage"));
};

I saved the file and use "make package" command and it proceed without error!

 

 

Adding 2 or more dot functions Guide

 

 

 

Regular: Throws error

%hook OkCupid.OKMessage
-(BOOL)read {
return TRUE;
}
%end

%hook OkCupid.OKProfileQuestions
-(BOOL)showUnansweredState {
return FALSE;
}
%end

Wrong way:

%hook CupidMess
-(BOOL)read {
return TRUE;
}
%end

%hook CupidQ
-(BOOL)showUnansweredState {
return FALSE;
}
%end

%ctor {
    %init(CupidMess = objc_getClass("OkCupid.OKMessage"));
    %init(CupidQ = objc_getClass("OkCupid.OKProfileQuestions"));
};

Throws "error: re-%init of %group _ungrouped, first initialized at Tweak.xm:xx"

 

A way around the error template:

%hook AnyRandomNameHere
- (id)description {
    return %orig();
}
%end

%hook AnyRandomNameHere2
- (bool)description {
    return %orig();
}
%end

%ctor {
    %init(AnyRandomNameHere = objc_getClass("ClassNameWithADotHere"), AnyRandomNameHere2 = objc_getClass("ClassNameWithADotHere2"));
  	/* Add a comma "," between both function. 
    AnyRandomNameHere = objc_getClass("ClassNameWithADotHere")
    AnyRandomNameHere2 = objc_getClass("ClassNameWithADotHere2")
  	*/
}

 

Final Code:

%hook CupidMess
-(BOOL)read {
return TRUE;
}
%end

%hook CupidQ
-(BOOL)showUnansweredState {
return FALSE;
}
%end


%ctor {
    %init(CupidMess = objc_getClass("OkCupid.OKMessage"), CupidQ = objc_getClass("OkCupid.OKProfileQuestions"));
};

I saved the file and use "make package" command and it proceed without error!

saved my day

P.S.: Do not use tabulator or other white spaces after "%init(", it will interpret it as an illegal classname (using theos git from 30.01.2018). After the first argument you are free to use what you want for pretty printing.
