In Objective-C why should I check if self = [super init] is not nil?
Hey guys, I have a general question about writing init methods in Objective-C. I see it everywhere (Apple's code, books, open source code, etc.) that an init method should check if self = [super init] is not nil before continuing with initialisation. The default Apple template for an init method is: - (id) init { self = [super in...
How does inheriting from NSObject work?
There are a couple of things about Objective-C that are confusing to me: Firstly, in the objective-c guide, it is very clear that each class needs to call the init method of its subclass. It's a little bit unclear about whether or not a class that inherits directly from NSObject needs to call its init method. Is this the case? And if...
Can I you use __init__.py to define global variables?
I want to define a constant that should be available in all of the submodules of a package. I've thought that the best place would be in in the __init__.py file of the root package. But I don't know how to do this. Suppose I have a few subpackages and each with several modules. How can I access that variable from these modules? Of cours...
Why are alloc and init called separately in Objective-C?
Note: I'm relatively new to Objective-C and am coming from Java and PHP. Could someone explain to me why I always have to first allocate and then initialize an instance? Couldn't this be done in the init methods like this: + (MyClass*)init { MyClass *instance = [MyClass alloc]; [instance setFoo:@"bla"]; return instance; }...

Cleanest way to define classes in Python?
I want to define classes in Python, but I'm currently putting them in modules, contained within packages. Is there a cleaner way of doing this? Is it okay to define classes in __init__.py of the package itself? I'm still learning how to arrange my Python source code, but this seems to be creating a slight ambiguity? Thanks to all! ...

Django Admin: Getting request in ModelForm's constructor
The below code removes certain values from a drop down menu. It works fine but I want to remove the value if the user lacks certain permissions.

C# Asp.Net User Control button click
In my code I load a user control (uc) in the page_load event. The uc contains a button which sets a label text to the textbox value. (lblTest.Text = txtText.Text) . This works fine in the load event of my page. But when I set the loading of the uc in my Init event, the label isn't set. When I set breakpoints, I see the button event is fi...
Confused when I see 'self' and '__init__'
I don't understand what these are used for, particularly the self argument? Could some please explain this to me and why on earth you would want to pass this in? Also, I've always thought __init__ was for 'initialisation', but it didn't occur to me that I've never had to put anything in here before. Could someone give me an easy example...
Is there any reason to choose __new__ over __init__ when defining a metaclass?
I've always set up metaclasses something like this: class SomeMetaClass(type): def __new__(cls, name, bases, dict): #do stuff here But I just came across a metaclass that was defined like this: class SomeMetaClass(type): def __init__(self, name, bases, dict): #do stuff here Is there any reason to prefer one ...
