I’m teaching iOS and Android at
QCon
on November 14–15, 2013,
so we have no class on Thursday, November 14.
We will add a class on Thursday, December 19.
- Thursday, October 3, 2013:
up to
Hello.
Memorize the two incantations, starting with the following.
“The
init
method of the subclass always
begins
by calling the
init
method of the superclass.”
Run the apps in
Class
and
Hello
and do the exercises,
but don’t hand them in.
Can you get the current price of IBM?
Create a project named
Oct10
that prints something interesting on the screen,
and upload it to a GitHub repository
named
Oct10.
Then look at the repositories of the
other students
in the class.
Bring your NYU NetID (not the number that starts with an uppercase N).
Read ahead to
Internationalize
and
Japan.
- Thursday, October 10, 2013:
up to
Japan
in the
in-class examples.
We also did
Dictionary.
Do the exercises in
Hello
and
Japan,
but don’t hand them in.
Create a project named
Oct17
and upload it to a GitHub repository named
Oct17.
The
Oct17
project should display text and graphics
(circles, rectangles, triangles, etc.),
with a
shadow.
Internationalize
it for at least one language other than English
(note: Klingon does not have a two-letter
ISO 639-1
code),
and give it at least one
icon
and at least one
launch image.
(It’s okay if your icon is one of the stupid yellow icons I made,
and it’s okay if your launch image is similarly unartistic.)
Then look at the repositories of the
other students
in the class.
The course will end as originally scheduled on Thursday, December 12th.
- Thursday, October 17, 2013:
up to
Animate
in the
in-class examples.
To undo the
transformations
(translate, scale, rotate),
see
CGContextSaveGState
and
CGContextRestoreGState
and let me know if they don’t work.
Write and upload a
touch-sensitive
app named
Oct24,
maybe with
animation.
And why not an icon?
Then click on the tip of each nose in the
class photo.
(See also the list under the photo.)
We’ll have a presentation about
winding numbers
on October 24th.
Here’s the
flyer for the group at Stern.
The student with the
app
in the app store
will talk to us on November 21.
His app is a tree map of Central Park,
and they’re having a nature walk to promote it on
Saturday, October 26, 2013 at 2:00 p.m.,
starting at the top of the Great Hill,
Central Park West at 106th Street.
- Thursday, October 24, 2013:
up to
Button
in the
in-class examples.
For
Mike’s
question about detecting which object was touched,
see the new example
Hit.
On October 24th, we tried to run
this project
in class.
We got the message
“/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang
failed with exit code 1.”
Here’s how I fixed it.
In the Supporting Files folder in the Xcode Porject Navigator,
I noticed that the PathTest-Prefix.pch
file was listed in red.
That means the file is missing from the project.
When I copied the -Prefix.pch
file from another project into this one,
naming it
PathTest-Prefix.pch,
the filename changed from red to black.
When I ran the project, I saw the
app’s Line/Fill/Clear buttons.
The coolest man who ever lived was
Derek Flint.
For example,
he was the first person to have a
ringtone.
Write and upload an app named
Oct31
for Mr. Flint to carry in his pocket,
with
background music
or
brief sound effects,
buttons,
and a
swinging (or peeling) door.
- Thursday, October 31, 2013:
up to
Date Picker
in the
in-class examples,
except that we skipped
Page Control.
Why is a
button
created with
buttonWithType:
rather than with the usual
alloc
and
init
like every other
view?
When you launch the
Notification Center
example on an iPhone or iPad,
does it display the string “Unknown” when it first appears?
Read ahead to view controllers to see what we’ll be doing next Thursday.
Write and upload an app named
Nov7
with lots of controls:
buttons
and
segmented controls,
sliders
and
date pickers.
Audio and video a plus;
you could even
record
audio.
Would anyone volunteer to investigate how to record video?
When adding a media file to your app
(graphics, sound, video),
follow the instructions in
this project
for adding the file to your project.
Make sure you check the checkbox for
“copy items into destiation group’s folder”.
After you upload your project to GitHub,
move it and all of its files to a different folder on your Mac.
Then download the project from GitHub and see if you can run
the downloaded copy.
- Thursday, November 7, 2013:
up to
L Train
in the
in-class examples.
I got the
Video
example to work in iOS 7;
the problem was that my video file was corrupted.
Examples that are less than one month old are iOS 7;
look for the date at the top of each
.h
and
.m
file.
I
really
think you should do
exercise #4 of
Navigate
(the “Go East” button)
and
exercise #2 of
Modal
(the “Done” button),
but don’t hand them in.
Please help me with
three unsolved questions:
- In
Text Field,
what difference does it make whether
textFieldShouldReturn:
returns
YES
or
NO?
- In
Video,
why do we see an echo of the status bar?
- In
View Controller,
why can’t we use
edgesForExtendedLayout
to prevent the view from growing to a height of 568 pairs of pixels and
overlapping with the status bar?
Write and upload an app named
Nov21
with a
navigation controller
on top of a row of view controllers.
No class on November 14th.
Read
About
App Distribution
in preparation for the November 21st talk by
the student with the
app
in the app store.
You can see him in
this photo:
red hair, beard, eyeglasses, white shirt.
- Thursday, November 21, 2013:
up to
Activity Indicator
in the
in-class examples.
Nov21-master.zip
has a
navigation
controller
on top of a row of
view
controllers
that display views with different images.
Write and upload an app named
Dec5
that does 60-times-per-second animation with a
CADisplayLink
in a view controller.
See
Pong
and
Pearls.
No class on November 28th.
- Thursday, December 5, 2013:
up to
Goner
in the
in-class examples.
Write and upload an app named
Dec12
with a
UITableViewController
and a
UITableView.
See the
Table
View Programming Guide.
Win a $500 raffle (there are four of them)
by filling out the course evaluation at

Your instructor
would be happy to invite you to join the team
if you give him your name and email address.
He will also register your device (iPhone, iPad, iPod Touch)
if you give him its 40-hex-character identifier,
and will create an App ID for you.
After you have joined the team,
go
here
to see who else has joined the team (click on People),
and go
here
to see your device and App ID
(on the left, click on Devices and App IDs).
Read
zip.html.
Get your
loginname
(same as your NYU NetID)
and
secret password,
if you don’t already have them,
for our Fedora Linux server
oit2.scps.nyu.edu.
If you couldn’t get a secret password from
start.nyu.edu,
contact the
accounts office.
One way to conact them is by calling (212) 998-3333 option 1.
Make it clear to the accounts office that you are trying to get a password
for
oit2.scps.nyu.edu,
not for Blackboard.
(They think everyone is a Blackboard user.)
The following examples constitute a
précis
of iPhone Part I X52.9236.
HelloWorldJapan: graphicsTouch:
touch the screenAnimate:
animationButton:
the target/action patternPLViewController.
In the previous example, the
application
delegate
created the
view.
In this example, the
application
delegate
creates a
view
controller,
and the
view
controller
creates the
view.
Nib:
create objects using the Interface Builder
by dragging them off a pallet.
Do the exercises in
Map.
Extra credit: instead of giving the
MKAnnotationView
an image such as
nyu.png,
could you give the
MKAnnotationView
a
drawRect:
method that is called whenever the
MKAnnotationView
needs to be drawn?
Could the
drawRect:
draw a different picture depending on the location of the annotation?
Another extra credit: can the overlay view be more elaborate than
a solid colored region?
How about a solid colored region with a border in another color?
Hint: class
MKPolyginView
is derived from class
MKOverlayPathView.
(We did paths
here.)
- Wednesday, October 13, 2010:
up to
Attitude,
except that I forgot to mention the “first responder”
methods in
Motion.
Click on the tip of each person’s nose in the
class photo.
Keep working on the map homeworks.
The
New York Times
review
of Euclid’s
Elements
suggests turning it into an app.
This app
from last semester
lets you draw a line with your finger.
Check it out: Android gives you the
area
and
pressure
of a finger touch.
iPhone gives you only the
location
of the touch.
- Wednesday, October 20, 2010:
up to the end of
Attitude
in the map section of the
in-class examples.
Could someone please tell me if
Attitude
actually works on an iPhone 4?
Does the black line point in the same direction?
Does the black line appear at all?
Here is one of the
Map.zip
files we fixed in class.
We also did
Objective-C and C++.
iPhone
Animation
meetup
during the same time slot as next Wednesday’s class.
Maybe I can convince some of my Thursday night iPhone Part I students to go.
Research question.
How can the shellscript at the bottom of
this page
run
sftp
non-interactively with the
-b
option on a Mac,
eliminating the need for
expect?
Exactly how would we use
ssh-keygen
(or whatever)
to allow
sftp
to connect to
oit2.scps.nyu.edu?
Research question.
Could we run the shellscript from the
Xcode
Organizer,
even though the shellscript require one command line argument (giving the
name of the folder that holds the project)?
Try to get the
Triangle
program to run on your Mac,
even though it isn’t an iPhone app.

Animation meetup notes.
- Wednesday, November 3, 2010:
there’s a simple solution to my iOS 4.0 vs. iOS 4.1
problem with OpenGL.
If you have 4.1, please create an iPhone project named Project, selecting
Choose a template for your new project: OpenGL ES Application
Do not make any change to this project that you get by default.
Save it in a
.zip
file and email it to me.
Do this after 12:45 p.m. on Saturday, November 6th,
when I get out of my Android class.
Thanks.
Can you do two different animations with the same object at the same time?
Does it work for explicit animations like the opacity and transform animations
here?
Does it work for implicit animations like the ones
here?
Can you find the official specs for the iPhone icon jiggle?
How many hertz (cycles per second),
how many degrees of rotation,
does the center of the icon move,
and if so,
along what path does it move?
For this remote database thing,
can you point me in the right direction?
Should I be looking at class
NSURL
in
this
document?
HTML 5
conference on Tuesday, November 9th.
- Wednesday, November 10, 2010:
Read the
Xcode template
for an OpenGL ES project.
Can you modify
this program
to make a stop sign instead of a square?
Can you modify
this program
to draw something more interesting than one triangle?
Can you run
this program?
- Wednesday, November 17, 2010:
Here are the four groups of extensions we can make to
the app that uploads an image file
to a server.
- Configure the name of the server and the 16-bit TCP/IP port number
in the Settings app,
and inform the app when the settings have been changed.
See
Configuring a Settings Page.
- Let the app get the imagesfrom the iPhone
camera
or photo albums.
- Find out what the delegate of the connection object could
do for us.
See the “delegate methods” of the delegate of an
NSURLConnection
object.
- Instead of relying on Safari to display the shared image files,
the app could download the image files and display them itself,
with appropriate ruffles and flourishes
(e.g.,
UIViewAnimationOptionTransitionCurlUp).
My torus program
is debugged.
- Wednesday, November 24, 2010:
No homework.
- Wednesday, December 1, 2010:
What projection is needed for a map printed on a sphere?
Google Maps gives us the Mercator projection by default.
Can we get the desired projection from Google Maps?
Here is Google’s
documentation
for creating a custom projection using JavaScript.
Is there any reason why
tga format
is the best format for texture files?
How can we use a different format (png, jpg, etc.) instead?
Find a beautiful image file of the Earth (or another planet)
that we can print on a sphere.
Anything we can use
here?
Is there an industry-standard layer we can put on top of OpenGL ES
to group primitive objects into higher-order objects and move them together?
