Overview

Requirements and technical facts Features Source control Project plan Code explanation Demo Project website

Requirements

Develop an application for the iPhone Must communicate with a web service. Must do basic database operations (insert,

update), using a web service.

Motivation

Why iPhone application ? Developing an iPhone application is

something new for all of our team members.

In this competitive environment of software development one has to have skills with cutting edge.

Learn a different paradigm for programming.

What does our app do?

Three features:1. Find the weather from the user’s current

location. 2. Finds restaurants in area, sends text

message to a friend in the address book, without the user typing anything.

3. Find friends in the area, and get directions to where they are.

Technical facts

Xcode is the IDE for developing iPhone and iPod Touch applications. Can only develop using Xcode on Macs.

Interface Builder is a separate program that works with Xcode to build the user interface.

Objective-C is the language. It is an extension of C, and combines Object-Oriented ideas of Smalltalk.

No automatic garbage collection, so must explicitly manage memory (by allocating objects and releasing them).

What is a web service? A method that you call remotely. The remote machine has access to some

resources or information that you need. Machine-to-machine communication, use

HTTP as the underlying protocol. Uses an XML-based format called SOAP.

Features

Feature 1 : Weather Update This feature finds the current weather, based on the

user’s current location. It uses the Core Location framework to get the user’s

current latitude and longitude. We then find the zip code from the latitude and

longitude from a web page http://geoplugin.net/extras/postalcode.gp?lat=29.24309&long=-94.8645&format=xml. It displays the page as xml, which we then parse for the zip code.

We use a web service which gets the weather, given the zip code.

We parse the SOAP response, and display it in a table view.
