iOS Learning Path

IOS Developer Roadmapstart Your journey today! Where do I Start?

becoming an IOS developer are a lot of fun and a valuable skill in today's market. But there's a catch:it isn ' t as easy as It looks.

Even experienced programmers is challenged by developing apps for a mobile device. And when your ' re just starting out, you ' re faced with learning a bunch of new Things:xcode and the IOS developer tools, th E objective-c programming language, the Cocoa Touch frameworks, and various other technologies in the IOS SDK. If you try to learn them all at once, it can be quite overwhelming.

So where does you start in the path to learning what to create IOS apps? Well, that's depends. There ' s no how-to article, book, screencast, or training course, everyone. You'll need the honest stock of your current skills and choose the appropriate resources. Here is some pointers to help you get started:

• If This was your first adventure with programming in general, the start by learning BASIC programming.
• If you ' re already a experienced programmer, but you ' re new to programming on the Mac, start by learning the developer too LS and objective-c and Cocoa.
• If you ' re comfortable with programming on the MAC and then jump right into creating your IOS app.
• Finally, if you ' ve already created a basic IOS app and then it's time to make it shine!

Not a Programmer? Creating IOS Apps from scratch is easy to look and it can be deceptively challenging even for experienced programmers. Many people underestimate what ' s involved. If you're not a programmer, and you had an idea for the IOS app, you'll likely get your idea to the market quicker by Working with an experienced IOS developer.

Basic programming

object-oriented Programming is a style of computer programming that uses concepts such as classes, objects, Metho DS, and inheritance. object-oriented programs also use more traditional programming concepts such as variables, loops, conditional statements, And so on.

objective-c is the Object-oriented programming language, the use of to create IOS apps. It's similar to other programming languages in many ways, but also significantly different on other ways.

#1 If You ' re new to programming in general, we recommend working through the following book:

Beginning Mac programming:develop with Objective-c and Cocoa
This was intended for folks who has little or no previous experience programming. It introduces the principles of object-oriented programming, Objective-c, and the Cocoa frameworks in clear, easy-t O-understand lessons.

 Get comfortable with the Developer Tools

The IOS SDK is a set of objective-c frameworks (libraries) and tools which allow you to create apps for IPhone, IP Od Touch, and IPad devices. It also includes IOS Simulator so you can run your apps on your Mac during development.

Xcode is the IDE used for MAC and IOS programming. It is created by Apple, and included in the IOS SDK.

A Mac is the instantly-recognizable computer that's now has an excuse to buy! Seriously, the whole toolchain is mac-only, and you need a MAC, the have an Intel processor to create IOS apps.

#2 Download Xcode and the IOS SDK:

• To develop your IOS app, you'll need to purchase Xcode from the Mac app Store ($4.99). The IOS SDK is included in Xcode.
• Once you has an app which is want to test in a device and distribute on the app Store, you need to apply to the IOS Devel Oper program. The program costs $99/year for individuals and $299/year for in-house enterprise apps. Program members can download Xcode for free.

#3 Xcode can look intimidating at first. Before you dive to coding, we recommend watching the following free video tutorials:

• Xcode 4 Project Setup (6 minutes, QuickTime)
• Xcode 4 Interface Overview (minutes, QuickTime)
• Using Interface Builder in Xcode 4 (minutes, QuickTime)

Then check out our full series of free Xcode 4 video tutorials.

Learn Objective-c and Cocoa

objective-c is a object-oriented programming language used primarily to develop IOS and MAC apps. However, it ' s a general purpose programming language. To build sophisticated apps, you'll need some libraries that does the heavy lifting for you.

Cocoa is a set of objective-c frameworks (libraries) created by Apple, enable you to develop apps for the MAC . Cocoa Touch is based on Cocoa, but was used specifically for developing mobile apps that look and feel like the familiar AP PS on your iPhone or IPod Touch. Cocoa Touch provides all of the core user interface components you'll need to develop graphical, event-based IOS apps.

#4 If You had a programming background, but you ' re new to the Objective-c language, we recommend watching the fol lowing Video tutorial:

Coding in OBJECTIVE-C 2.0
This Three-part video series would give you a overview of all the major features of the Objective-c language and the core Concepts of object-oriented programming. You'll also learn how to manage memory, which are especially important on IOS devices!

 

#5 then , once you ' ve had a look at objective-c, you ' re-ready for some Cocoa. We recommend working through the following book:

Cocoa programming:a Quick-start Guide for Developers
This book would give you a better understanding of Cocoa fundamentals. The IOS SDK uses many of the same concepts, and a good working knowledge of Cocoa, would serve you well. Work through the "exercises to get" hands-on experience with the tools, language syntax, and basic COCOA concepts.

 

#6 Join a cocoaheads group:

Cocoaheads is a group devoted to discussion of Apple computer's Cocoa Framework for programming on Mac OS X and IOS. Cocoaheads groups meet in a number of locations, worldwide! If you can ' t find a cocoaheads group, consider starting a new group.

Create Your IOS App

putting it all together for the first time is exciting. Here's where all your foundational work really pays off. When you ' re comfortable with the language, libraries, and tools, you can start turning your idea into reality.

#7 Consider learning in one's our acclaimed hands-on training courses:

• Attend a public course and learn all the major features of the IOS SDK so you can develop mobile apps like the pros.
• Schedule an on-site course to quickly get your team up to speed on IOS development. On-site courses is ideal for teams of 8 or more developers.

You'll learn how to create an IOS apps directly from the experienced developers offering expert guidance and instruction.

#8 If You are Tinker, experiment with Apple's sample IPhone apps:

Apple has provided a number of sample IOS apps. Download The source code, run it in the IOS Simulator, and then start experimenting. Reading through the code is a great the "to cement" what's learned about Objective-c and Cocoa. And you can use the code and design from these samples to inspire your own development.

#9 Many books about IOS development is now available. Here is a couple recommendations:

IOS SDK Development
This pragmatic guide takes you through the tools and APIs so can use to create your own software for the IPhone, IPa D and IPod Touch. Packed with useful examples, this book would give you both the big-picture concepts and the everyday ' gotcha ' details that Developers need to make the most of the IOS platform.
