iPhone SDK Tutorial Part 4 TabBarController showing WebView and MapView

Here we develop an application presenting multiple views using using a tab bar controller. The tab bars presents a web view and a map view. We also add icons to the tab bar items.

The video is a lengthy, and goes into more depth with explanation of what the code does. Not just a how to, but also a how so.

You can download the source code for the app here:

okay so we're gonna call what was it
again on
load request load request and again here
tells you that this is gonna be in an
issue or I'll
requests and that's what I'm gonna do
here than at the end bracket in here so
we don't forget
and we're gonna have to do a com
bracket around the house to call
soul word will do here Xanadu NS
you are now request
and again you
drill down to API reference
and om one thing you can do here's call
a class
class method called request with URL
okay
soul we're gonna call om
the NS you're all request and we're
gonna do a request with your oil
request with your own and it's going to
require an
and this URL URL URL type
okay fine om go ahead bracket that
and men were gonna say alright
arm jumped to
request with you are home and
Tom it's going to be an issue we're all
type the URL
alright arm and
she you are now
URL with strain is the first thing I
suggest
now the URL which train om
isn't oh and it's not your father's
click on that
and Tom and
on URL which train is another class
class method you call on
on an issue RL and you type in your
on HTTP address in here
okay now this is kinda bomb
in again when I would recommend you do
is on each one
these items are doing he PI look at the
API
reference can read on it and she miss
can make sense to you
arm when you first look at this economy
going wall while you know
why didn't happen just haven't have a
simpler method that you can call on the
UI web you to say
are load URL which train
and I jus use this would seem simpler
system having an
just part of a nested on I guess
a URL which train returns and an issue
are well which a request with your all
requires organise your own requires that
you have to give to a load request
mean it's kind of a on its kinda silly
bun on but it these are one of the
matter is that you
om me 12 our copy
and keep in your general Xcode
development chichi
so I have windows she cheats and
on there's like these little on
on nice to nose matter good and
Tom and I
wrote this down so wanna my lessons you
know lot of notes that I have here
and one on them here's some this
on on loading web page for case we're
adding web you into a view to find you I
be outlawed
so basically on you define the IB outlet
and then you just copy and paste
this particular code in to Nick so you
have to remember this whole long thing
on the other thing is that term in
object-oriented
a program is a book by Stephen cohan
programming in objective-c 2.0 I'll
where he talks about the define method
and from where you can define
for example a long string like that and
then put that in your code
I side looked like to get to know your
thoughts about maybe using something
like that instead of using this point
you know do you without maker
code Tom more usable or less usable
on II I'm I B
curious about what people think about
them anyway
com so now we have this awake from
nearby in basically what this
says the view controller arm this is
basically a delegate
function or method that basically says
hey on
not I execute this once you
you load your name into your view and
so we going to do a control a command P
for to save
and compile lists and an hour do not
wish
on command shift are and then command
are to run a program
to see if we'd load are web page
man we didn't okay our home
up pass the word korea justice into
put in www cartoonists to pay dot com
don't have to put the WWW in there so
maybe we just put in
participate on com build
command shift car
and their this all right below to web
page and
I'm and it's all good alright so
on and here's our map you
but there's no back and forwards and
will cover that another another topic
but that basically includes the the
webpage arm the other thing also want to
show you a quick
is on 10 things you can do that for
debugging
is you can put in little things like and
as long om
at and put some kind of them
any kind a statement here okay so here
we call
the web
page load request in the awake
from in him on
method aren't
so uncontrolled on come and be honest
whoops I'll some a column of course
command be command shift are
and noticed when you then
run your program you'll see
that some this message
gets called in your debugger consul so
this is a good debug method you can play
season is long over
in your code so something's not working
complacent in their cunts UK what it's
called what does in
and because sometimes you know math
never gets called you scratch your head
winds
happen but after concludes our are
I'll our tutorial hope farm
you well I liked it it was helpful the
only questions please comment
I will be responsive and any other
thoughts or ideas that you have
mom I would greatly appreciate it talk
to you guys soon
happy participation
