Iphone 线程 NSCondition NSThread - xinghexiyue的专栏. 多线程在各种编程语言中都是难点，很多语言中实现起来很麻烦，objective-c虽然源于c,但其多线程编程却相当简单，可以与java相媲美。 这篇文章主要从线程创建与启动、线程的同步与锁、线程的交互、线程池等等四个方面简单的讲解一下iphone中的多线程编程。 一、线程创建与启动 线程创建主要有二种方式： - (id)init; // designated initializer- (id)initWithTarget:(id)target selector:(SEL)selector object:(id)argument; 当然，还有一种比较特殊，就是使用所谓的convenient method，这个方法可以直接生成一个线程并启动它，而且无需为线程的清理负责。 这个方法的接口是： + (void)detachNewThreadSelector:(SEL)aSelector toTarget:(id)aTarget withObject:(id)anArgument 前两种方法创建后，需要手机启动，启动的方法是： 二、线程的同步与锁要说明线程的同步与锁，最好的例子可能就是多个窗口同时售票的售票系统了。 // SellTicketsAppDelegate.h import <UIKit/UIKit.h> @interface SellTicketsAppDelegate : NSObject <UIApplicationDelegate> {int tickets;int count; NSThread* ticketsThreadone; NSThread* ticketsThreadtwo; NSCondition* ticketsCondition; UIWindow *window;} @property (nonatomic, retain) IBOutlet UIWindow *window; @end SellTicketsAppDelegate.m 文件 三、线程的交互线程在运行过程中，可能需要与其它线程进行通信，如在主线程中修改界面等等，可以使用如下接口： - (void)performSelectorOnMainThread:(SEL)aSelector withObject:(id)arg waitUntilDone:(BOOL)wait 包含如下线程操作方法: 推荐方式.
How to add CoverFlow Effect on your iPhone App – OpenFlow - microchenhong的专栏. Hello all, The main criteria of this post is to help you add a cool effect called the “cover flow/open flow” effect to any of your iphone apps. This is cool in two ways actually. One it adds animation kind of effect to your app and the other, its very easy to build too. I got to learn about this effect when I was working on my “pianos” app where in i’ll have bunch of animals to select which would be displayed as a menu using this “cover flow” effect. Once a particular animal is selected your piano view for that animal comes up. My piano app will be out soon and you can check that out. The source for this post is the link displayed below. “ Based on his post I have simplified things further.
Creating the project Firstly Create a new “view based” project with project name like “CoverFlow”. Add the OpenFlow source code to your project Adding OpenFlow source code to the project.

Iphone应用程序开发指南（读书笔记 2 ） - 今年我们二十五六 - 51CTO技术博客. 创建一个新的视图对象时，需要为其分配内存，并向该对象发送一个initWithFrame:消息，以对其进行初始化。 举例来说，如果您要创建一个新的UIView 类的实例作为其它视图的容器，则可以使用下面的代码： 在iPhone 程序中，有两个地方最常用于创建视图和子视图， 它们是应用程序委托对象的applicationDidFinishLaunching:方法和视图控制器的loadView 方法。 调用父视图的addSubview:方法来添加视图，该方法将一个视图添加到子视图列表的最后。 调用父视图的insertSubview:...方法可以在父视图的子视图列表中间插入视图。 调用父视图的bringSubviewToFront: 、sendSubviewToBack: 、或 exchangeSubviewAtIndex:withSubviewAtIndex:方法可以对父视图的子视图进行重新排序。 调用子视图（而不是父视图）的removeFromSuperview 方法可以将子视图从父视图中移除。
创建一个带有视图的窗口 - (void)applicationDidFinishLaunching:(UIApplication *)application { // Create the window object and assign it to the // window instance variable of the application delegate. window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; window.backgroundColor = [UIColor whiteColor]; // Create a simple red square CGRect redFrame = CGRectMake(10, 10, 100, 100); UIView *redView = [[UIView alloc] initWithFrame:redFrame]; redView.backgroundColor = [UIColor redColor]; // Create a simple blue square // Add the square views to the window.

("to-many key not allowed here") Programming The iPhone For Accessibility By The Visually Impaired. Per Busch, a blind iPhone user from Germany, has been on a crusade to raise developer awareness about VoiceOver, a new-in-3.0 accessibility enhancement. Per’s is a noble quest, so we’ll do our part here: VoiceOver Over View VoiceOver, says Apple, “describes an application’s user interface and helps users navigate through the application’s views and controls, using speech and sound.”
Apple offers a concise document that describes how accessibility is delivered with iPhone 3.0. I’ll further distill what’s involved: VoiceOver literally describes what’s on-screen in spoken word. You can label your UI from an inspector panel in Interface Builder. Supporting this level of accessibility isn’t hard. Standard UIKit controls/views support accessibility by default. Limitations, And A Wish-List For Apple Per shared an email conversation with Daniel Ashworth, CEO & Chief Architect of Quokka Studios about the limitations of the VoiceOver.

把Iphone程序连接真机调试--中国移动开发者社区. 对于真机调试，首先要在苹果网站上注册APP ID，以及购买iPhone Develop Program(iDP) 开发者授权，99美元。 然后要创建证书请求CSR，创建步骤如下： 设置OCSP和CRL为关闭状态。 Mac OS 中，打开应用程序，找到 钥匙串访问（Keychain Access）工具打开主菜单 － 证书助理(Certificate Assistant)－从证书代理请求证书（Request a Certificate From a Certificate Authority）输入iDP注册时的email，用户名自定义，选择“存储到磁盘”，选择‘Let me specify key pair information’。 选择保存路径，证书请求创建成功。 1.接下来就可以登录iDP Portal提交证书请求了,到这个页面 点Development，‘Request Certificate’，然后点Browser，添加刚才生成的证书，点submit。 点击Approve，一分钟后会生成一个.cer文件。 下载Download，双击它。 单击“好”，就可以把certificate加入到keychain里面了。 2. 打开XCODE，在window菜单下，点击Organizer，出现这个页面（前提是要连上真机哦） identifier那一行字符就是device id了，复制它。 点击“Add Devices” 给device name取个自己的名字，把之前复制的字符粘贴到Device ID那，点下面的submit就可以了 3. 申请IDP图文教程 | App Store上线/推广/销售讨论区 - CocoaChina 开发讨论区 最热的iOS开发论坛| 最热的Mac开发论坛 | 最热的iPhone开发论坛 | 最热的iPad开发论坛.

Before you begin using Three20 in your project, you should decide what directory layout works best for you. Recommended: Shared Layout In this layout, Three20 is shared between multiple projects. If you need to make project-specific modifications to Three20, use git branches. If you are unfamiliar with git, it's highly recommended that you learn the basics in order to take advantage of this directory layout. Directories Example workflow Submodule Layout In this layout, Three20 lives directly within each project's folder as a git submodule.
There are two primary means of adding Three20 to your project. Automatically add Three20 to your project Three20 includes a python script that adds Three20 to Xcode iOS projects. In order to add Three20 to your project, it's recommended that you do the following: This will add the Three20 module and all of its dependencies to your project.

The operating system that powers Apple’s iPhone and iPad devices, iOS, has proved incredibly popular with developers. A large part of this is almost certainly due to the opportunity that the App Store gives developers to make money, but the great development tools that Apple provide, in the form of XCode and Interface Builder, and also the Objective-C programming language, which iOS developers are required to use, certainly play their part.
The iOS SDK that developers use to build iPhone and iPad apps is relatively low level, requiring the developer to do a lot of work to get their app up and running. Fortunately there are lots of third party libraries available that provide useful functionality that can make your life as an iOS developer much easier. Here we discuss 10 of the best: MBProgressHUD – Progress Indicator Library Many official Apple apps have a nice translucent progress display.

This tutorial is outdated, proceed at your own risk. Introduction to custom three20 cells In my last tutorial I showed you how to use CSS-like stylesheets in your iPhone Apps. Although I did make a custom cell I didn’t really show how this is done, and I’ve decided to go into a bit more detail. In this tutorial I am going to show you how to make custom table cells in your iPhone Apps using Joe Hewitt’s Three20 library .
Custom cells are very useful, they let you do things like this: But it’s worth mentioning that i’m not going show you how to make a complete iPhone App, nor install the Three20 library in your Apps (there is already a guide on how to do this on the three20 github page ). By the way, all my Three20 tutorials are available on gitHub .
First things first, There are cells, and there are fields. control the labels, images, interface elements, etc that are actually displayed when a table cell is rendered.
