IOS Development Learning Notes

Recently want to learn the development of iOS, in NetEase Open class to find a course, ready to listen to this course, as a primer.

The course's name is: Stanford University Open Class: ipad and iphone App development (IOS5)

Links: http://open.163.com/special/opencourse/ipadandiphoneapplication.html

Today, I listened to the first lesson and probably said something like this:

2. IOS Overview

   IOS devided 4 Layers:

   1. Core Os:unix kernel and C API

   2. Core service:object-oriented Service API

   3. Multimedia:multimedia is embed into the system design

   4. Cocoa Tough:user Interface Library, service library
      

4. Mvc

   Devide all your classes into 3 camps:

   Model:what your application does

   Controller:how your model is presented in the UI

   View:controller ' s minions, the controllers uses it to present the model on screen

   The Model-view communication:

   1. 1. The controller can access the model

      2. The model never communicate to the controller, it defines notification to broadcast things interesting to controller

The Controller-view communication:

1. 1. 1. Controllers uses an outlet to talk to view

      2. View can ' t communicate to the controller via:

         1. Target/action mechanism

         2. Delegate (Should/will/did)

         3. Controller works as data source, delegates for model

            
            

Controllers can talk to many models and other Controllers, but view can only is controlled by only one controller,and Neve R communicate to models.

3. Objective-c

A strict super-set of C

Header file As. h, source file as. m

#import works like #include, Smarter (good!)

@interface and @end in header file

@implementation and @end in source file

Public versus private is just it's in header or source file (good!)

Can has @interface in source file, be private

Arguments is interspersed in the name of the methods (great!)

(void) Orbitplanet: (Planet * aplanet): ataltitude: (double*) km;

@property (nonatomic) double topSpeed;

@synthesize topSpeed = _topspeed;

Call a method

[self topSpeed] = Self.topspeed

[Self. Nearestwormhole traveltoplanet:aplanet Atspeed:speed]
