This project focuses on developing an innovative iPhone application that taps into user location to provide three main features: current weather updates based on the user's location, restaurant searches with the ability to send text invitations without typing, and a friend locator with directions. Using Objective-C in Xcode, we leverage web services for data retrieval and ensure a smooth user experience with intuitive design. This app not only enhances our developer skills but also offers practical solutions for everyday tasks.

  2. Overview • Requirements and technical facts • Features • Source control • Project plan • Code explanation • Demo • Project website

  3. Requirements Develop an application for the iPhone • Must communicate with a web service. • Must do basic database operations (insert, update), using a web service.

  4. 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.

  5. What does our app do? Three features: • Find the weather from the user’s current location. • Finds restaurants in area, sends text message to a friend in the address book, without the user typing anything. • Find friends in the area, and get directions to where they are.

  6. 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).

  7. 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.

  8. 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.
