Delphi Cookbook - Second Edition

By: Daniele Teti

Overview of this book

Delphi is a cross-platform Integrated Development Environment (IDE) that supports rapid application development for Microsoft Windows, Apple Mac OS X, Google Android, and Apple iOS. It helps you to concentrate on the real business and save yourself the pain of wandering amid GUI widget details, or having to tackle inter-platform incompatibilities. It also has a wide range of drag-and-drop controls, helping you code your business logic into your business model, and it compiles natively for desktop and mobile platforms. This book will teach you how to design and develop applications, deploy them on the cloud platform, and distribute them within an organization via Google Play and other similar platforms. You will begin with the basics of Delphi and get acquainted with JSON format strings, XSLT transformations, unicode encodings and various types of streams. We then move on to more advanced topics such as developing higher-order functions and using enumerators and RTTI. You will get an understanding of how Delphi RTL functions and how to use FireMonkey in a VCL application. We will then cover topics such as multithreading, using the parallel programming library and putting Delphi on a server. We will also take a look at the new feature of WebBroker Apache modules and then ride the mobile revolution with FireMonkey. By the end of the book, you will be able to develop and deploy cross-platform applications using Delphi .

Using iOS Objective C SDK classes


Just as we saw about Android in the previous recipe, Delphi is able to access the iOS SDK as well. In this section, we'll talk about the mechanisms that the compiler offers to import classes from the iOS SDK. This is not a standard recipe but is more of a show-case showing the possibilities offered by the Delphi compiler and the process needed to fully use them when dealing with OS built-in libraries. The mechanism is similar to the Android ones, but there are some notable differences.

Getting ready

In Objective-C, all classes have NSObject as a common ancestor. iOS SDK is composed of some frameworks. An iOS framework is a number of classes specialized for a single purpose. For example, UIKit is the framework containing all the basic classes related to the UI, the iAd framework contains all the stuff related to the advertising and MapKit wraps up all the mapping related classes.

Note that Objective-C uses the NSString objects while Delphi uses strings. If you...
