so hello and welcome to the tutorial so
today I'm gonna be and my name is Tammy
Bakshi and today I'm gonna be talking
about an app that I created and this app
was written in Swift which is Apple's
programming language for Mac OS X and
iOS 9 or iOS 8 and it also works on iOS
9 so yeah this app will essentially
allow you to take a borrower's name and
I am named and also an image of the
items that they borrowed from you and
upload it all to a database on the web
so that you can access it from any other
device whenever you want yeah so this
app is mainly targeted towards people in
you know grade 11 grade 12 that are
trying to do computer science maybe
making a project then and they need to
upload images to a database it would
work for them it could work for even
professional app developers that are
actually trying to create apps that need
to actually upload images that the user
gives them onto a database stuff like
that and yeah I'm just going to go to
our Mac now and you will see the app in
action so as you can see here I have my
iPhone here and so I already have the
app up and running and so as you can see
this is a UI tableview in which all of
the entries are put in so we have Frank
took my mouse and then a picture the
mouse Travis took my well it was
supposed to be marker but again
autocorrect made it market so apparently
he took my market but as a picture of a
marker there and then Tom took my
glasses and then picture their glasses
and then Tim took my USB extension and
then the picture of the USB extension
and so now that we have all these why
don't we actually try uploading
something so to say we upload and let's
just say the person in this name is
Frankie
and then let's just say the item that
they took or my headphones that could
work so now I'm just gonna choose an
image and as you can see here I'm just
going to take my headphones take a quick
picture and then as you can see it asks
me if I want to take a retake or if I
want to just use the photo so I can
click on use photo and as you can see
after a little bit of delay which is one
of the known bugs in the app it will
actually start spinning the UI activity
indicator view which will tell the user
that it's uploading and also this back
button here is now disabled so that we
cannot go back while the uploads because
then it would be in between and
operation and then the next time you
would open the app it would just crash
so once this is done uploading and again
sometimes it takes longer than other
times but usually it's quite fast 30
seconds to a minute
at max so usually this can be done in
like 15 to 20 seconds sometimes if your
Wi-Fi slows 30 seconds and if it's
really slow or if it's a really big
image and it'll take around a minute so
as you can see the uploading bars gone
and the back button is now enabled so if
I click on back you will see that the
back button gets clicked but then we're
still at the view like what happened I
don't know but what actually happened is
it's loading up the images from my
website and it's putting them into the
table view so it's downloading each
image again and it's basically putting
each one into the table view one by one
so if I just wait a second this will in
fact just load up the entire UI
tableview with all the entries and we'll
also have additionally Frankie took my
headphones and then a picture of the
headphones just so I can make sure that
they're not damaged and just really make
sure that they're mine so yeah that'll
load up in a few minutes until then what
we can do is I'm just going to minimize
that and let's just go oh as you can see
it has loaded up and as you can see we
have the classic entries that were
already there
right to her mouth Travis took my marker
Tom took my glasses and took my USB
extension however if I scroll down here
in just a second sometimes it freezes up
like that a second again this is a
pretty big app so it does take some time
to load up so as you can see I can
scroll down even more and it says that
Frankie has taken my headphones and then
a picture the headphones so now that
you've seen a slight demo of the app
let's actually get let's just skim
through the source code here and as
always the source code will for sure me
in the description 100% on github like
always
and so this Apple essentially take the
swift parts and the objective-c part
makes it together and the the iOS end
which is both Swift and objective-c will
contact PHP PHP will upload the image to
web server on my GoDaddy and the name
the item and the name of the actual
image itself will go to the database so
that we can store it and then this is
the UI for the app you should see you've
already seen this but we have the reload
upload the name of the person the item
they took and an image of the item
inside of a costume table view cell and
then we have the UI for the uploading
which is the name of the item the name
of the person sorry and then with the
item then you can choose an image you
can go back and it will tell you if it
is currently uploading apart from that
we have view controller dot select which
will do some basic stuff you know it'll
it's basically the heart of the entire
app itself it controls the entire PHP
and the database and the web server it
just does everything that its little
branches can so in just a second here
and as you can see we have an extension
to the string class which will allow us
to get specific ranges of character were
actually just specific characters itself
from strings and also apart from that we
have a class view controller which
conforms to UI view controller
datasource and UI tableview delegate
it'll also conform to UI navigation
controller could I'll get and
uiimagepickercontroller delegate apart
from that this is just all some
variables and IB outlets we are
declaring then we have a function called
buted load and this function is called
whenever we whenever we run the app and
this function over here is called
whenever a boolean updates meaning
whenever we're done uploading this
function over here is the reload
function it's called whenever we click
on the reload button this button will
basically hide the keyboard whenever we
touch somewhere on the screen this
function here will get JSON values from
my websites or actually from the
database and put it into the table view
and this function will tell us how many
rows in the section there are for the
table view and this function will
actually be able to make a cell for each
cell that's required in that table view
this IB action will allow us to start
taking a picture this function will
allow us to pick an image and then we
can put that from the image picker
controller to the actual web server
itself and the database and this will
allow us to get all the contents inside
of the well basically all the names of
the images inside of the ID the inside
of Mike from my database and then this
function will just allow us to parse out
all those names from the all data and
yeah that was really it for this
tutorial please subscribe if you if
you're new to the channel like the video
if you liked it comment if you have any
questions you can even email me and I
will get back to you as soon as possible
and yeah I hope you guys liked at Khan
Academy most importantly and yeah that
would be it goodbye
