[Pyobjc-dev] Translator needed to begin my journey

[Matt L. <jm...@gm...>]

Hey guys, I am trying to learn Objective-C. All of my current programming
background is in Python and this new syntax isn't sitting well with me. I
have been reading tons of documentation and seen loads of tutorial videos,
but I'm just not quite picking it up yet. I would be really appreciative if
someone could translate this sample Python code into ObjC so I can make all
the connections in my head. I think it will give me the kick start I really
need to dive deeper into the language. Please be sure to include both header
and implementation so I can see the whole picture.

Thanks in advance!


#!/usr/bin/python

# This section to show class and method structure
class Employee(object):
    def __init__(self, name, salary):
        self.name = name
        self.salary = salary

    def nameUpper(self):
        return self.name.upper()

    def giveRaise(self, percent):
        self.salary *= (1.0 + percent)


# This section to show normal function structure
def printHeader():
    print 'Company HR'
    print '-' * 20
    print ''


def main():
    printHeader()
    matt = Employee('Matt', 100000)
    print matt.nameUpper()
    print (%s: %d) % ('Old Salary', matt.salary)
    matt.giveRaise(.20)
    print (%s: %d) % ('New Salary', matt.salary)


if __name__ == '__main__':
    main()

Matt,

I've attached the thee (!) files that translate your code as well as
an Xcode project to build and run them. I've made use of the
Objective-C 2.0 @property and @synthesized getters/setters. In this
case you could get away with using the instance variables directly
(though this is bad practice in ObjC because it exposes the
implementation and it's hard to convert to properties later, unlike
Python).

Cheers,
Barry

Barry,  you cant begin to know how helpful that is! Thank you so much! I
really appreciate the level of detail and the helpful tips and info inside
the code. I have just glanced over the files and it already makes 100% more
sense to me. I cant wait to start learning and coding more.

Thanks again!

Matt
