here with your very first

video series

called how to build your first iphone application

and my goal with this YouTube channel is

exactly like it sounds to teach you guys how to build iPhone and iPad apps

this first video series

is going to teach you guys the basic skills and get you guys familiar with

xcode

it's going to be about

eight videos long i think

and by the end of it

you're going to know

basic skills like

creating buttons and

creating composite views

learning what

app architecture means in iOS

uh... how to hook up handlers and using delegates and stuff like that

so

in this particular video we're actually going to

take a look at what we will be building for the next eight or ten videos; I have the demo

ready

and i will tell you guys where to download XCode, so you can

get your environment setup

and then we will

go and set up on our first XCode project

so let's get started!

So this is a demo of what we will be building. It's a dice roll simulator

and as you can see, all that does when you click the roll button is

randomly generate

two random numbers between one to six and then

show their dice representation on the screen

So it's a pretty simple application but it's going to serve the purpose of

teaching you the basics of iOS app architecture

some objective c basics as well as

getting familiar with the xcode so by the end of

this video tutorial series

you're going to know how to handle button clicks

and how to build an iphone view comprised of smaller views, you're going

to know how to load images

and

show text labels

stuff like that

in terms of environment, you don't even need

an actual iOS device at this point. All you really need is a Mac.

You need to download XCode which is free

and as you can see during your development phase you can use this

simulator that comes with XCode

to

to load up your app to see how it's working and stuff and

it comes with

all sorts of cool features like you can rotate it you can you can

simulate shake, you can simulate memory warnings and

you can even

you can even put in a custom location

if you wanted to debug

GPS specific functionalities.

Okay so

the easiest way to get XCode is to download it from the app store

you can search for XCode and it's gonna show up as first result

If you

don't have the Mac App Store for any reason you can still download

the

image.

So all you need to do is

hit this URL right here.

You're going to have to sign up for a

a free

developer account

and

once you do you're going to be able to access this page and download

this image right here.

XCode 4.5.2 is the latest one.

So once you have xcode installed

let's go ahead and launch it

and make sure you pull down the menu here

and go to "About XCode" just to doublecheck what version you're running.

As of the time of this video, the latest version is 4.5.2

And just make sure you're not running anything older than that

because sometimes your Mac may come pre-installed with

XCode. Or maybe you've bought a used mac which already has xcode

and then sometimes

you'll have two icons and you'll end up using the wrong one.

So just make sure you're using the latest version.

And when you launch XCode you may see a welcome to XCode menu.

In my case i don't have that

but if you do have that you're gonna see a button that says "create new project".

so go ahead and click that. For me, i'm going to go through the menu system

which will be the same thing so i'm gonna create new project here

It's going to bring up a window

that allows you to select a couple of templates just a start off your

iOS project.

and make sure that you're under the iOS heading

and under "Application"

so there's a bunch of different

templates you can use and you might recognize some of them especially

the tabbed application which is very common in the app store

but for our

demo dice roll app, we're going to use a single view application.

Here you're specifying a couple properties for your project. You can

change these later but

for now,

give your demo app a name. I'm going to name mine "iPhone App Tutorial"

For organization, you can put your own name and for company identifier

this is going to be really important when you start to deploy your applications

to devices and stuff like that

because

once we get into provisioning and

basically setting up our app

to deploy our on real devices

it's going to matter.

What this is, is going to matter. Normally, the convention is going to be a

top level identifier

and then a secondary one and finally your app name.

You can select

what type of devices you want this to run on

and again

selecting one doesn't mean that

it won't be able to run on

the other.

You can always tweak these settings in the build settings,

the project properties later.

And what's more is that, let's say I select

iPhone and then I wanted to

also allow this run on iPad to have iPad specific views, i could definitely

add iPad specific views and change my project settings later to allow it to run

on iPad. So don't feel like this is set in stone.

But for our demo we're going to select iphone.

We're going to leave

"use storyboards" checked off.

And maybe in the future, i'll do a tutorial on how to use story boards.

You definitely want to have "use automatic reference counting" checked.

You guys might have heard

back then before

iOS5,

developers

had to manage their own memory and that was a huge barrier for people learning

objective c and iphone/ipad development but nowadays, we can have

xcode automatically do that for us so

go ahead and have that checked off and you can leave unit tests

checked.. unchecked i mean.

Click next; its going to ask you where to save it

and

there we go! We have our project created.

By default it's going to dump everything in the root folder and i usually like to

organize this a little bit better.

I think I'll go through that in the next video.

For now, all i want you guys to do is

in this top menu right here

choose iphone 6 simulator and then just hit "Run"

to see that simulator pop up and see your app.

So there you go,

you don't have anything in this application right now so it's showing you an empty

screen.

But that's

pretty much our "hello world".

So i'm gonna end the video off there

and look forward to the next one where i will

it'll probably be about showing you guys

all the different parts of xcode

and getting you familiar with that and maybe revising some of how

this is structured here and organizing the project.

Alright until next time;

Comment especially if you have some questions and you have stuff you don't

understand. That's where i'll be checking and answering your questions.

And please follow along if you want to get the most out of this.

Okay until next time. Bye!
