objective c - Cocoa, NSProxy, How to take over a method in an object? -

-

I need to convert a method to an object with its own implementation. For example,

< Pre> person * p; // some object NSMutableArray * array = [NSMutableArray array]; [Array addObject: p];

How do I change addObject with one of my own methods?

In other words, is there a way to change the implementation of addObject: of a specific object with another implementation?

I'm playing around NSProxy but I did not know what I should do.

Any help would be highly appreciated.

Thanks

With a different implementation for that method, Make an example of the square.

Obfuscating Python code? -

I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
