hello there and today I am back with
another tutorial this time I'm going to
be going over a second revision of one
of my most popular tutorials in the link
to it will be down in the description
below this is going to be a tutorial on
how to include a search bar into my
database assets
now what this deck basically does is
it's the same that what that we had
before the only thing we're doing is
we're adding a search bar to it so
basically as you can see I have a UI
here it's just going to load up the
storyboard and so I've just added two
more things here a search bar and a
little label so inside of this inside of
the search bar we have a some
placeholder text and this placeholder
text is type string to search and click
return so basically it's telling you to
search something you have to put
something in here and click return on
the keyboard and then to clear the
search as you can see or move all the
text and hit return so that's basically
how the UI is and so basically you need
to have watched my previous tutorial in
order to fully understand this one and
the full source code for this tutorial
will be down in the description so if
you haven't checked it out already
please go do check it out and then you
can come back and revisit this tutorial
ok so as you can see I have an extension
here to the string class and I'm doing
is I'm adding a function called find in
strength I'm taking a parameter called
string defined as a string and then
returning a boolean sorry so what I'm
doing is I'm checking if self is not
equal to nothing meaning I haven't self
is equal
to something then if self as and as
string since and a string has an easier
contain string method well then if self
is in a string dot contain string and
then whatever string you wanted to find
as a lowercase string so it's not
case-sensitive
then return true however if it's not
then returned false and if self is equal
to nothing then just return false
straight so next what we're doing is we
have all the normal functions it's just
that we are declaring two new variables
data second and search and we're also
creating a new iboutlet called text
field search then what we're doing is
inside of the text field should return
the function we are basically setting
the data second array to nothing and
then we're checking if the text fields
text is equal to nothing and search is
equal to false and self dot reload
meaning it's setting in search variable
to false and it's reloading at the
tableview else what we're doing if the
text field has text in it and they
clicked enter then we're going for for I
in data so we're looping through the
main data array and then we're checking
if I so basically the actual array
inside of the data array and the name
parameter which we are getting from the
database as you should know if you
watched my previous tutorial and just as
a little thing here I'll just show you
as you can see well
okay I'll just run the app for you till
then was just got a PHP myadmin and yeah
so as you can see we have two rows in
the database name and additional info so
this will only search the name so we
have all of these variables going from
the database to this app as you can see
so basically always we need to do now is
search these names and we're going to do
that by saying if the name is string
because it's it's an any object when you
get it and as a lower case string as I
said so that we have the same case not
find in string text field text then data
second dot add object I so we're adding
that to a specific element since it has
whatever you're searching for in it and
then we're setting search to true and
we're reloading ourselves now you must
be wondering how are we putting those
search results inside of the table view
well that's really really really simple
all we're doing is in the number of rows
in section function we are checking if
you're currently searching then returned
data second count if you're not
searching then return data count and
then inside of the cell for row at index
path function for the table view we are
declaring a new NS dictionary called
main data and we're checking if you're
searching then datas and then if data ii
is not equal to nothing so there's
actually something that you have
searched for and you have a result then
the main data is equal to the second
array of data specifically that index
path that were at the
specific role we're at as nsdictionary
so then we have basically have all the
data from what you've searched else if
you're not searching then just set it to
the normal database data then what we're
doing is we are creating a variable
called cell as a custom cell and I'm
using the additional info cell class and
you should be familiar with this if you
watch my previous tutorial and then we
are just setting the text name and
additional info labels to whatever
they're supposed to mean
and then we're just returning the cell
and so if I test this out really quickly
let's say I search for what should i
search something with an A and and and
minute and if I click enter on my
keyboard as you can see it comes up with
Tanmay and if i remove everything and
click enter so you can see everything
comes back let's say I search something
with an O in it anything with an O
everything with an O will pop up and you
sing with a teeth yeah and then anything
with enough nothing you saying with a G
people to know now which I already did
and P problem yeah so that's basically
how all of this works subscribe if
you're new to the channel comment for
any suggestions improvement so if that's
a question I definitely do like the
video if you liked it and yeah I'll see
you goodbye
