Help/Support Kinds of Returns

xC3FFF0E · May 3, 2015

Can't find any results on internet.

My question is:

What are kind of "Returns" besides on 'nil' (NULL)?

Another one is what is the return code of 'pass-through'?

Any help is appreciated!

You can return everything to anything ."Pass-through" or how you Flex people call it is %orig

so to clarify, there is no more or kinds of return right? And the pass-through if we put it on tweak.xm it is %orig. am I right?

What do you mean 'kind of returns'. You can return what you want there are no restrictions (except function cast) how you return a method. Nil and NULL are not return types. It's just one of many ways.

You shouldn't stick with Flex terms. They get you mad in Objective-C coding a lot because you feel urged to translate the code word by word but that's not how it works.

- (void)callMethod {
}

- (void)callMethod {
%orig;
}

is the same, however 'pass-trough' at arguments in Flex means that they are just not used but not in Objective-C

I get it and it work. I tried.

In short, putting this on the tweak.xm will give you this:

nil = Zero (NULL)

%orig = (The 'pass-through' in Flex) Set to original.

Meanwhile, -(void) cannot be change.

You can only modify an -(id) with 2 ways. The 'nil' and the '%orig'.

Which you'll needed a "return".

Example:

return nil;

return %orig;

This what I understand. And I tried it, it works 100%

You get it

- (void)callMethod { }

disables a method by the way because nothing gets executed. Also you can return an id more than 2 ways but nvm for now. %orig always calls the original code so it doesn't change if you return it to an id
