Delphi Cookbook - Third Edition

By: Daniele Spinetti, Daniele Teti

Overview of this book

Delphi is a cross-platform integrated development environment (IDE) that supports rapid application development on different platforms, saving you the pain of wandering amid GUI widget details or having to tackle inter-platform incompatibilities. Delphi Cookbook begins with the basics of Delphi and gets you acquainted with JSON format strings, XSLT transformations, Unicode encodings, and various types of streams. You’ll then move on to more advanced topics such as developing higher-order functions and using enumerators and run-time type information (RTTI). As you make your way through the chapters, you’ll understand Delphi RTL functions, use FireMonkey in a VCL application, and cover topics such as multithreading, using aparallel programming library and deploying Delphi on a server. You’ll take a look at the new feature of WebBroker Apache modules, join the mobile revolution with FireMonkey, and learn to build data-driven mobile user interfaces using the FireDAC database access framework. This book will also show you how to integrate your apps with Internet of Things (IoT). By the end of the book, you will have become proficient in Delphi by exploring its different aspects such as building cross-platforms and mobile applications, designing server-side programs, and integrating these programs with IoT.

Using iOS Objective-C SDK classes

Just as we saw regarding 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 more of a showcase 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. The iOS SDK is composed of some frameworks. An iOS framework is a number of classes specialized for a single purpose. For example...
