Objective-C

Objective-C is a high-level, object-oriented programming language that was developed in the early 1980s. It is primarily used for developing applications for Apple's macOS and iOS operating systems. Objective-C is an extension of the C programming language and adds support for object-oriented programming features such as classes, methods, and inheritance.

Objective-C was originally developed by Brad Cox and Tom Love at Stepstone Corporation. It was later acquired by NeXT Computer, where it was used as the primary programming language for the NeXTSTEP operating system. When NeXT was acquired by Apple in 1997, Objective-C became the primary language for developing applications for macOS and iOS.

Objective-C is known for its dynamic runtime system, which allows for features such as method swizzling and dynamic class loading. It also supports a message-passing syntax, which allows objects to communicate with each other in a highly dynamic way.

In recent years, Objective-C has been largely supplanted by Apple's newer programming language, Swift. However, Objective-C is still widely used in legacy code and in certain specialized applications.

swiftui object-c对比

SwiftUI is a new framework introduced by Apple in 2019 for building user interfaces on all Apple platforms (iOS, iPadOS, macOS, watchOS, and tvOS). It provides a new way of declaratively building user interfaces using Swift code.

Objective-C, on the other hand, is an object-oriented programming language that has been widely used for building Mac and iOS applications. It has been around for much longer than SwiftUI, and has a large and established developer community.

Here are some key differences between the two:

1. Syntax: SwiftUI has a simpler and more intuitive syntax compared to Objective-C, which can be more verbose and difficult to read.

2. Declarative vs Imperative: SwiftUI is a declarative framework, which means you describe what your user interface should look like, and the framework takes care of rendering it on the screen. Objective-C, on the other hand, is an imperative language, which requires you to write code to manipulate the user interface elements directly.

3. Interoperability: SwiftUI and Objective-C can coexist in the same project, and it is possible to use SwiftUI components in Objective-C code. However, the reverse is not true, as Objective-C code cannot be used in SwiftUI.

4. Learning Curve: SwiftUI is generally considered easier to learn for new developers, whereas Objective-C has a steeper learning curve.

Ultimately, the choice between SwiftUI and Objective-C depends on the specific needs and preferences of each developer and the project they are working on. Both frameworks have their strengths and weaknesses, and both can be used to build high-quality and performant applications.
