Come lo stesso nome suggerisce, l'Objective C è un'estensione a oggetti del linguaggio C.Esso mantiene la completa compatibilità col C (a …

Objective-C is a general-purpose, object-oriented programming language that adds Smalltalk-style messaging to the C[3] programming language. Originally developed by Brad Cox and Tom Love in the early 1980s, it was selected by NeXT for its NeXTSTEP operating system. Objective-C was the standard programming language supported by Apple for developing macOS and iOS …

Objective-C implements the runtime binding using a mechanism called a selector. This helps make the process a lot more efficient — as you might imagine if a method lookup really had to go through and compare the actual names of the methods letter by letter it would be very slow. Instead, at compile time Objective-C converts every method name ...

The Objective-C language proper (as opposed to coding practice) allows you to have the effect of “hiding” an inherited method by providing an override that calls the “does not understand” method. Furthermore Objective-C allows a conceptual “is-a” relationship to exist apart from the inheritance hierarchy (subtypes don’t have to be ...

C++ is a middle-level language that is being run on various cross-platform operating systems such as Windows, UNIX, Macintosh OS, etc., whereas Objective C is a general-purpose, object-oriented programming language used by Apple in its operating systems and APIs Cocoa, etc. C++ supports data hiding, encapsulation, inheritance and polymorphism ...

Aug 18, 2021 · Well Objective C’s roots actually hark back to Smalltalk (one of the classic languages that introduced object-oriented programming, along with Simula), and of course C. Smalltalk has influenced other languages like Java, hence the similarities. So really Objective C might have some new syntax, but the concepts that underly the language ...

Blocks are a non-standard extension added by Apple Inc. to Clang's implementations of the C, C++, and Objective-C programming languages that uses a lambda expression-like syntax to create closures within these languages. Blocks are supported for programs developed for Mac OS X 10.6+ and iOS 4.0+, although third-party runtimes allow use on Mac OS X 10.5 and iOS 2.2+ …

Formal declaration. In Objective-C, a class can also be declared formally using the @class SomeClass syntax. This is called a forward declaration in Objective-C, but because this term has a different meaning in Pascal, we have termed this a formal declaration in Objective-Pascal.. A formal declaration of an objcclass instructs the compiler to assume that somewhere, there is a …
