Beginner’s Guide to iOS Development: Building Your First App – Part II In the first part of our iOS tutorial I took you through a guided tour of the iPhone app development. We got a deeper look at Xcode 4, and also took a very short tutorial on building iPhone app. The beginner tutorial was written for anyone who is looking to get into programming iOS apps. Today, we’ll get into the second segment of the topic, where we will be building a fully-functioning iPhone application. At the end of the tutorial you will get an application which can’t be pushed into the iPhone since it will need you to purchase developer program, but we can run it inside the iOS Simulator on a Mac OS X system. Note: You will need a computer with Macintosh Operating System (Mac OS) for Xcode installation, application development and app submission, there’s no way you can do it on Windows legally. Pre-Setup: Installing Xcode Packages If you haven’t done so already you will need to get Xcode 4 on your computer. 1. Hit “Next” and you’ve got to enter a name for your project. 2. 3. 4. 5.
How to make iOS/Android games on a PC – for free • Andy Moore I’ve gotten a lot of EMails over the last few days demanding to know how I can make mobile games on a PC. Some ask about Android, most ask about iOS, and everyone is all jaw-agape that AS3 code runs on these devices in some sort of native format (as opposed to in a browser instance). Then they get all wobbly in the knees when they figure I’ve done it using completely free software. There are plenty of (IMHO: Over-complicated) tutorials out there, and my knee-jerk reaction is to just … well, LMGTFY. After all, I didn’t divine this knowledge myself; it came with a bunch of research, and thankfully following the path of other people. I think I can simplify most of the tutorials though. Step 1: Boot up your PC. These steps are for Windows operators only. Step 2: Install FlashDevelop. When I say “install FlashDevelop” I mean for you to install the latest version (4.0.1 RTM at the time of this writing). Step 3: Start a new project in FlashDevelop. This one’s easy. Step 8-ish?

Comparison of the Available iOS Charting Libraries In this post, I explore four of the available iOS charting libraries and investigate the features, API, and pros and cons of each. In order to conduct a fair investigation, I have developed a comparison framework which loads historic stock market data from the Yahoo Finance API. My findings were that Core Plot had a strong set of documentation, yet was a little light on features and built in functionality. The Framework The framework can be easily extended to display the data fetched in different view controllers that can be set up to use various charting libraries. Framework Library / API Usage Rather than generating random data or using the same hard-coded data every time the comparison was run, stock market data is fetched from the Yahoo Finance API in CSV format . Framework Structure The framework is based around a Data Transfer Object (DTO) named StockPriceDataContainer. The Data Manager has two operations which fetch data to display in the framework. The Libraries Core Plot iOS:Chart
How Much Does It Cost To Develop an App | iPhone App Development Costs Table of Contents Types of AppsApp Development ProcessDevelopment CostsDesign CostsTotal CostsFree iPhone App Quote Overview In the past two years, the app market has exploded. In under 9 months the Apple store reported over a billion downloads, and then doubled that number in half the time. And for good reason. The good news? Let’s talk about what goes into getting an app developed. Types of Apps You Can Develop There are many different kinds of apps you can develop. Basic table functionality – think about this as a hierarchy: opening screen has big topics and you click one and you now have a set of new lists to click on. The type of app you want to develop may change based on how much content you have and how much control you want to have over the entire process. App Development Process The app development process can be broken out into four major parts – idea, layout and planning, design, and going live. 1. 2. 3. 4. iPhone App Development Costs iPhone App Design Costs Total App Costs Carter
You’ll never believe how LinkedIn built its new iPad app (exclusive) Guess how much of LinkedIn’s new iPad app is actually mobile web and not native. Go ahead — guess. We’ve had a lot of fun asking people to guess this over the past couple days. They’ll start with 40 percent and edge up to 70 percent, but no one comes close to the real figure: 95 percent. Yes, only one screen in the entire LinkedIn iPad app is actually native. We were shocked to hear this 95-percent figure from Kiran Prasad, who heads up LinkedIn’s mobile development team. But the new iPad app had struck us as so surprisingly sexy during our initial review that we had to know more about how Prasad and his team of four (yep, just four devs built this app) packed so much punch into a web app for a tablet. Especially as Silicon Valley tech companies pick sides in the web-versus-native war, it’s fascinating to see the presumably conservative LinkedIn lean toward the more progressive side of mobile technology.

Programming with Objective-C: Encapsulating Data In addition to the messaging behavior covered in the previous chapter, an object also encapsulates data through its properties. This chapter describes the Objective-C syntax used to declare properties for an object and explains how those properties are implemented by default through synthesis of accessor methods and instance variables. If a property is backed by an instance variable, that variable must be set correctly in any initialization methods. If an object needs to maintain a link to another object through a property, it’s important to consider the nature of the relationship between the two objects. Although memory management for Objective-C objects is mostly handled for you through Automatic Reference Counting (ARC), it’s important to know how to avoid problems like strong reference cycles, which lead to memory leaks. Properties Encapsulate an Object’s Values Most objects need to keep track of information in order to perform their tasks. Declare Public Properties for Exposed Data
How much revenue can I get from iAd? As for 1, I was in the same situation as you. Since I went with iAd only and the ad only actually gets displayed for users in countries where iAd is available, I decided I had to put a limitation on the app as well as ads. My app is a webcam viewer, and the free version limits the number of webcams you can add, disables slideshow mode (one of my favorite features from the paid version) and disables import/export/saving images support. I made it clear in the app with a popup on launch that these features are available for $1. At first I thought maybe I don't even need to encourage them to upgrade because the iAd revenue from lots of users could be better than the one time $0.70 revenue if they buy my app. If I were you, I would put some limitations on the ad based version but make those limitations relatively minor so the user can still enjoy the free app, just give them a good incentive to upgrade as well. As far as where the ads can be displayed, I'm not sure.

ios - What kind of leaks does automatic reference counting in Objective-C not prevent or minimize Macintosh Performance Guide: Latest News How to write your first BlackBerry application – Lesson 1: UI fields This article is the first in a series of articles about BlackBerry development. With App World, third party software vendors and the web, there are a ton of opportunities for an independent developer to make money. BlackBerry Development in Java – Lection 1: Basic fields in the User Interface Let’s get right into it. Download the JDE (Java Development Environment) from the BlackBerry website. For advanced features and other APIs you may want to use, you need code-signing keys from RIM. For this introductory application, you don’t need signature keys and the compiled *.cod file can be run on the device (and not only on the simulator). After installation of the JDE, launch it and then click on: 1. Then on the left side in the JDE, you see the Tab Files. 1. That’s how the ‘Files’ should look like on the left side of the screen: The *.java Files: We have two *.java files for our Project. A BlackBerry application always starts with the main() method.
