#interface Foo {
Bar *bar[12][8][2];
}
And I am wondering what that means and what it is actually doing behind the scenes?
bar it is an array of 12 elements. Each element is an array of 8 elements, and each element is an array of 2 pointers to "Bar" objects.
No surprises -- It is a multi-demensional array of pointers to Bars.
In MRC, reference counts are managed manually.
In ARC, they are managed for you.

So, I am currently making a 1942-style game. How can/should I set up the path for my enemies? I know I could do it with CGPathRef but is there an easier way to do it? It seems pretty out of place for more complex paths like for example these 2 I'd like to implement:

(Sorry I can't directly post pictures, I need at least 10 reputation)
Or at least, I haven't found any documentation explaining how to create more complex shapes with CGPaths.
So what are your recommendations?

I am looking for a way to simply create a form in Objective-C. I tried to build one using a table view, but this one does not handle the return key correctly and does not look very apple-like. Is there a "right way" to do this?
Table view is the best control for this. Create a custom cell with UITextField. Handle return key in you UITextField.

I'm getting into iOS and coming with an Android background. Will I have to manually allocate and remove memory in Objective C? I'm getting conflicting answers from blog posts... How does ARC fit in to this?
Yes it is, ARC is the garbage collection system in iOS that checks for nil references and then auto deallocates the objects for you. You still have to manually allocate objects yourself.

What reasons are there to pass an argument to an initializer in objective C? I can't find the information.
When a class operates on (and thus requires) an external object. An example of this is NSScanner, which iterates through substrings in an NSString.
When a class can be instantiated using already known information. An example of this is -[NSArray initWithArray:], which copies the contents of another array.
