Advanced iOS Programming for iPhone® & iPad® Apps

All HOTT courses are available face-to-face, remote-live, on-demand or on-site at your facility. 

Participants in this hands-on course will develop apps to interact with many of the hardware systems available on iPhone, iPad and iPod Touch hardware devices.

Students will learn how to use the camera and microphone for still images, videos and audio. The course includes coverage of the Core Location and Map Kit for GPS systems and the motion systems for the internal gyroscope system. 

Students will learn how to save and read files for local systems and how to use the Core Data system to create local SQLite databases.

Students Will Learn:

• Using templates to create applications in Xcode 
• Designing applications for multi-platform devices 
• Designing user interfaces for multiple screen resolutions and aspect ratios 
• Using advanced views to create complex user interfaces
• Accessing the device's camera and microphone 
• Integrating with the Mail app, Messages app, Calendar app and Reminder app 
• Saving files on the device to create data persistence
• Loading and parsing XML data from a stored file 
• Using Core Data to more easily store and fetch data of different types 
• Using encryption and keychain to secure data such as usernames and passwords 
• Creating shapes, images, paths, and colors using Core Graphics
  Animating objects using Core Animation 
• Using the device's accelerometer and gyroscope to detect movement and orientation 
• Responding to multi-touch and gesture user interactions 
• Localizing the user interface based on language and region 
• Using MapKit
  Using Core Location to access GPS data 
• Implementing UIDynamics into user interfaces

The course emphasizes Service Oriented Architecture (SOA), and students learn how iOS apps interact with Web services through request/response systems. Hands on practice includes implementing code to access a web service asynchronously using SOAP.

Attendees also learn how to develop apps incorporating iCloud support, and the requirements for sharing documents

Comprehensive hands on exercises are integrated throughout to familiarize students with many of the hardware systems and concepts needed for iOS apps, as well as security concerns to address prior to launching iOS apps. Exercises include use of the redesigned iOS7 UI controls and many of the new features of the latest release of iOS.

Course Prerequisites: Strong experience with Objective-C programming language and basic iOS application development. HOTT's iOS Programming for iPhone and iPad Applications Using Objective-C course strongly recommended.

Note: Classes do not have fixed location. Prior to each class they examine the geographical location of the enrolled students and then select a venue that will provide most convenient overall access for the students. Classes are held in hotel conference rooms and exact location is determined 2 weeks prior to the course date.
