iOS 9 Development using Objective-C

Description

Duration: 5 Days

Description

This five-day course explores the language, tools, and libraries required to build “native” iPhone/iPad applications with iOS 9. Developers can choose from three different starting points depending upon previous iOS experience (from no experience to minimal view controller experience).  This course starts at the beginning of the development process, identifying what is needed to obtain the iOS SDK and continuing with a thorough exploration of Objective-C, the native programming language for iOS. After all of the necessary foundations are established, the iOS 9 SDK and its related development tools are introduced, providing a detailed examination of views, controls, view controllers, and their event based lifecycle.

Throughout the course, concepts are reinforced through “hands-on” lab exercises.  The culmination of these exercises result in an iPhone / iPad app that is intended to be used by attendees of a software development seminar (including a “master-detail” schedule of sessions, attendee notes, map / directions to the venue location, and display of a live website).

Learning Objectives

•  Build iPhone and iPad applications with the iOS 9 SDK
•  Master the underlying programming language, Objective-C
•  Discover the tools and APIs used to build dynamic user interfaces
•  Delve into the methods in which user input is collected
•  Improve code quality through Unit Testing
•  Explore advanced programming concepts including Persistence and Concurrency

Audience

Experienced object oriented software developers who are new to, or have minimal experience with, Objective-C and the iOS SDK.

Prerequisites

Strong development experience in any Object Oriented programming language.  Students should feel very comfortable with concepts such as Inheritance and Polymorphism.
