Objective-C is a high-level 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. Due to Apple macOS’s direct lineage from NeXTSTEP,[4] Objective-C was the standard programming language used, supported, an

最近ではコンピューター、ウェブ、モバイルでゲームを楽しめるようになりました。これらのゲームプログラミングについて学びましょう。 ゲームプログラミングの特徴 ゲームプログラミングは比較的新しいジャンルです。 ゲーム開発に使用される言語は、C#、C++、JavaScript、Swift、Rubyです。ゲームでは通常のアプリケーションと異なり複雑なビジュアルを操作するパフォーマンスと速度が要求されますので、プログラム言語もそれに特化している言語がおすすめです。 ゲームプログラミングは今後も人気の職種です。習得してステップアップを目指しましょう。 Oracle PLのプログラミング言語について学びましょう。 Oracle PLの特徴 SQL、T-SQLと同様にOracle PLもデータベースを処理するための言語です。違いとしてはOracle PLは世界最大のデータベースのひとつであるOracleデ

図形を描画するプログラムを作成する。 プロジェクトの作成 Xcodeで「GraphicsEx」という名前のCocoa Applicationプロジェクトを作成。 「HelloWorld」と同様に「GraphicsView.m/GraphicsView.h」を作成。 FrameworksにQuaartzCore.frameworkを追加。 「HelloWorld」と同様にインターフェイスの作成。 ソースコードの記述 GraphicsView.h #import <Cocoa/Cocoa.h> #import <QuartzCore/QuartzCore.h> //GraphicsEx(View) @interface GraphicsView : NSView { } //色の指定 - (void)setColor:(CGContextRef)c r:(float)r g:(float)

The PyObjC project aims to provide a bridge between the Python and Objective-C programming languages. The bridge is intended to be fully bidirectional, allowing the Python programmer to take full advantage of the power provided by various Objective-C based toolkits and the Objective-C programmer transparent access to Python based functionality. The most important usage of this is writing Cocoa GUI
