SXSW - iPhone Dev

Dave strongly suggested I go to this...so here's some notes.

browser devs don't consider system resources when developing

browsers have built in status/progress indicators

iphones don't have any of that – how to do that?

Iphones are asynchronous and should think consider multithreading

Objective-C, what is it?

C w/OO added

Different from web languages

pointers

memory management

non-linear code execution

syntactical old-school

Gotta use Xcode

Cocoa – the display/interface framework – interactions are asynchronous

Protocols

https, u/p authenticated, REST, JSON (rest is considered best practices because it's lighter)

Demo & Tutorial:

MVC, events & delegates

Use Xcode to pull templates down onto the gui

AppDelegate is like the master controller and is where the app is initialized – has to be AppDelegate.m

below that sits models and views

use http://code.google.com/p/json-framework/  to parse json

Memory Management

if you alloc/init then you have to release it

if you don't, do not release cause you could cause exception

use instruments to profile apps, cause you need to be able to respond to release memory request
