iPhone SDK Tutorial Part 1 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.

You can download the source code for the app here:

well hello I the system
with burkhart is a bit and this is my
first tutorial
on your iPhone SDK development
and the topic recovering today is
I'm gonna show you guys how to had
different views
arm with using a tab bar controller and
before we get started
I wanna give a shoutout to been
HD iPhone are which is a
which is a channel on you too
up which has
a whole bunch of are tutorials
my goodness arm has a budget Orioles
and are he also gives a tutorial
on how to harm do when I'm but sure you
but I'm giving you my own
arm had it twist on
the topic up but I encourage you to
check him out because great
has a budget greater tutorials
are the other thing is there's no
affiliation between participating
an HD icon okay
so will get started with Xcode
a prison Mexico sorry open we gonna do
pay
new project and was gonna do Windows
based application
and going to call it tutorial
I'm you call it whatever you like we did
in college Toro
tutorial expand this opens up
and the basic Windows are application
Creek and just comes with it
I an app delegate and
are under resources it comes with a main
and zip file alright so it's fairly
sparse are what we gonna be doing is it
going to be
working mostly in the Interface Builder
and will start out with that are
by double-clicking on Main window zip
and dots it's also often called
are got
names except for historical reasons so
that newborn im
sensor arson arts cinemas okay so the
the main I'll are mean
on documents window here is usually
given with these icons I like to switch
this over to
eight missed you and they'll become
apparent shortly
the windows we don't really need us and
arm what we're going to do is we were
going to go
to Windows two controllers
and would have been adhere is tab bar
controller okay and the tab bar
controller
comes with its own some views
and has everything in it to
harm to render the views and everything
else
okay so that is really nice and are so
basically instantiates that when you
called this object
into the documents window debase
instantiates archer
I'm arm but did object is not connected
to anything yet and walk to the actual
now the other cool thing weird do years
arm you can and are
different tap or items Inc to you
no at more top or items from at
you the can 2.1
so we'll call this our first aren't you
web
the web time and this one will call it
I am map I and
now the only things that you may want to
adhere is are
and notice that if I'm down click here
you can see
what this happen troller basic insist up
we could consist the staff are which
thus you right here
and Tom farrakhan's with to
are new controllers and a few
controllers
controller in particular taps okay so I
can click on the tab for the tab view
controller
and the inspector will show the various
parameters
of those particular items I'm she could
do to hear
or through here but here you know
exactly which er which a look
okay and that's why this is better than
us okay because if you want to come here
opens up another you know it it doesn't
show
what's really going on here I'm so
are one thing's me want to adhere is in
this particular time
bar is we are you renamed it to where
and to this one too now but you will
have some mom
pictures in here to do that you go to
resources
and when at pictures to your resources
because under the zip file if I wanna at
image
nothing there there's not much okay so
are one thing is want to refer you to
is another great utility on the web
called a glyph ish
I think their design house there's no
affiliation participate include fish but
they have this great
are iPhone icons
and you can download us and once you
download it
are you can view that in your downloads
and
we r download this but basically it's
will create icons folder into subfolders
various stuff in it you import these two
items here
okay and you go to explode go back to
those
and just drag used to folders
under resources okay on select Copy
an ad and now you can I have
your icons or your resources so going
back to
Interface Builder you can now looks
up for that you too bill
pregnancy all it'll help build the
project and
want to build it'll Pisa icons will be
be a ball and Interface Builder alright
so now i click down on
all these icons are available to you so
I'm just going to
I'm sure there's a map well actually
there's a map
icon which is kinda cool here map
magnify
map marker man
mother call did
me when you get the point arm
I should just pick a random one but but
she's become that's kind of cool
cool about
ami p map pan
map marker I'm and
and want to go to the other one go to a
bar up that was
we did for the wrong one on offer the
right okay web one
I for the web tab lots
pic pay and
now now okay well to speak
Spica camera
but I'll alright so now you have your
pictures are you icons for
your your tap bars and
arm and now would want to do is you
wanna connect just have our controller
to the app delegate okay included
outlets for the app delegate
there's nothing there yet so we're gonna
have to go to back to Xcode
on the classes and we're going to have
to
hi declare any tab bar controller
I variable or
pop pay tab bar controller
object pointer variable
okay arm cycle you I
tab bar
controller pointer type
which is the star are call it
route tab bar
comptroller now why am i calling this
root app controller so when things are
going to cover into my tutorials and not
just
how to do this but some general thoughts
regarding harm
programming practices now I'm
fairly new to programming and
us we have to take everything with what
I say with a grain of salt nine by
comments
arm and ideas regarding this but arm
but my thought is that you want
naming conventions are
are can go a long way to help self
document your code
and so you wanna pick names that arm
are could be helpful and
making other people be able to region
code now
since are tap our control is going to be
review
I mimics a the route our controller if
it was part of another sub you
and the delegate arm was are
are reference somewhere else then No
and let's say that's up to you was part
of the scheduler something
saying arm I would perhaps call this the
scheduler tab bar controller
arm again this is a just an idea
and
