Help/Support Question regarding the hooking method

[kevindurant35 30 8]

I am trying to use the hooking method to create a code from a flex patch I have on my device.

I am trying to set id to null (please see the link below) and I am not sure how to do it. 
Below you can see the flex unit I am trying to edit.

Your help would be greatly appreciated. 

Thanks in advance.

This is the basic Template:

%hook TargetClass //TargetClass from Flex
- (void)productPurchased:(id)product //Target Method from flex, MAKE SURE to add names after :(id), :(bool), :(int) etc
    name = nil; //Set the argument to nil (null), use the name you provided for the argument
    %orig(); //call %orig;, Note how the method is - (void), if it was something else, use "return %orig();"
}
%end

You result should be: (Please don't look this before attempting to fill out the template above, so you can actual learn)

 

%hook MyLessonsViewController
- (void)productPurchased:(id)product {
   produc = nil;
   %orig();
}
%end
