I am very new to programming and have never used cocoa touch...
I need a bit of help continuing with this tutorial http://www.raywenderlich.com/4756/how-to-make-a-catapult-shooting-game-with-cocos2d-and-box2d-part-1
I have finished with it and it all works fine, I now want to add a menu page which when the application loads it will go to, then a "start" button to start the application... and once level 1 is completed (all enemies destroyed) the next level will start.
Could anyone help me in achieving this, I will happily pay someone to just edit the code for me so I can then continue with adding the levels, I just need a base so then I can just repeat steps etc.
Many thanks,
Alex.
The problem with just working from tutorials and others' code is that you become limited to doing what others have done instead of innovating. Getting started with stuff like this can be challenging, but the best way to go about it is to try to understand it bit by bit. I'd recommend working on a simpler project first; stuff that involves physics can get gnarly. I feel your pain; sometimes I wish for nothing more than for my code to write itself and carry out my vision, but I just have to push through and keep trying to understand what I need to know to make things work. If you haven't already, you should probably look for some more basic Cocos2D tutorials to see how things work and fit together; once you've done that, figuring out a menu system should be pretty easy.

I lack any knowledge in xcode, cocoa touch or c+++ etc. Now, I am going to try to make a photography app, where I got a tab bar, and 4 undercategories. At the first category, I want it to be a grid of photos who can be enlarged by touching them. I really don't have time to learn more about programming for a couple of months. How is this achieved in the easiest possible way? I am currently leaning towards AQGridView, but since I have zero knowledge of the area I cannot fully understand the instructions. Now before you ask why I want to make an app without any sorts of knowledge, let me answer it. My father is a photographer, and wishes to get an app. If I manage to make one for him, I can get loads of jobs where his photographer friends pay for an app. And if I have already made it, I will probably have a template from the earlier project to take advantage from.
So, in conclusion, my question is: How do I make this possible in the easiest way possible?
Thanks.
Sounds like a great candidate for the new UICollectionViews. There are many grid frameworks out there, but if you have any experience with TableViews on iOS, CollectionViews are a breeze to get up and running quickly. One of the best resources for learning and implementing CollectionViews (outside of the API docs) can be found here:

20,000 lines of spaghetti code (iPhone ObjC) was just dropped in my lap. QUESTION: where to begin, is there a tool to just profile it all? It's a mess, not even sure where to start. Suggestions welcome.
What you're looking for is something called Unified Markup Language (UML). This is a critically overlooked part of the development process and is used to layout "class names, methods, links, etc".
Luckily for you, your problem has been faced by many a programmer in the past and there are a few different Magic Bullet solutions available. Since I've never worked backwards from code to UML (normally you build the UML first) I had to do a quick search to find some solutions:
This one looks promising: doxygen
or this one: AutoGraf
And I'm sure with a few minutes on Google you can find everything you need if these don't work out for you; now that you're aware of UML.

I've never programmed for an iPhone before, but have the coding experience to get by with learning Obj-C. I've been trying to come up with a good first project so that I can learn a little about the process involved with mobile development.
My idea was to make an app composed of 5 questions. Users would check off a box for each question representing "yes", "no", or "maybe", sort of like a survey. There would be a submit button at the end and the data would be sent to an email address. I figured the idea/concept was simple enough, but does anyone with iPhone experience think this is going to be too difficult to start with?
I really like the idea of creating a checklist in this first app, so any ideas related to that would be greatly appreciated. Not looking to make a usable app, just something to mess around with!
If you're just messing around to learn I suggest you pick up one of the many iOS books. A previous SO answer will have a list here.
Usually the books start out simply and explain to you really well what you're doing. They progress to more intermediate and 'advanced' topics and tutorials throughout the books and by the end you will have touched on many of the frameworks and API needed to get started on your own ideas.
Good luck!

I am very new to Xcode and am trying to learn as fast as i can.
As i am learning i would like to try and make a simple "question and answer" application for IOS. Like this:
Question: Is the moon bigger than a table?
Answer: "YES" or "NO"
And one of the answers is right the other is wrong. After you chosen your option and gotten a right or wrong answer i would like a new question built in the same way to appear.
So, first of all, is this kind of application even "easy" to make and if so do you know if there is some kind of tutorial that is similar to what i want to do? I've tried to search for hours now but i have not found anything.
If there is no tutorial would one of you want to tell my how to make one?
I know that this is a very big question to ask but it would be great if someone could help me!
Thank you!
Keep working on the learning. Don't worry too much about producing something useful yet -- you're trying to put the puzzle together before you've seen all the pieces. Break your problem down into much smaller problems:
How do I display text on the screen?
How do I change that text?
How can I put a button on the screen?
How do I find out when the user taps the button?
How do I read data from a file?
How do I write data to a file?
Once you understand the parts, you'll be able to put your Q&A app together pretty easily. If you try to get to the end goal without first learning the basics, you're going to end up frustrated with the process and building the app will take much longer than it would otherwise.
Use labels to display the question. YES and NO are two different buttons, that the user can click on. Each button is connected to an IBAction that tells the app which button the user clicked. The app then checks to see if that response is correct, and notifies the user if it is. Then, repeat with a different question. Good luck!
There are some wonderful resources online for the beginner. Heres just one:

These happen to be screencasts so they are easy to follow.

I'm doing some work right now for a small startup who wants to build a multiplayer game for the App Store. The basic idea is that users of the game can look to see if anyone else is online and enter a 2 player turn based game.
I have no experience with this kind of thing, so I'm not responsible for that part but we need to know the right kinds of questions to ask potential hires. Does apple provide a framework for what we're trying to achieve? What kind of experience would you expect somebody capable of setting this up and maintaining it to have? I know we'll need an SQL-server to manage accounts and stats and such, but beyond that I'm not too sure.
How would you get started tackling this?
I'd start by looking at Apple's Game Center, which was added in iOS 4: https://developer.apple.com/devcenter/ios/gamecenter/
(You will need an Apple ID to see that page).
Game Center provides much of the framework you're looking for. (Note: it's less than a year old, so you may find limited experience with your interviewees).
Apple provides Game Center for turn-based multi-player gaming.
