ElegantSnap

ElegantSnap(Base on SnapKit) to make Auto Layout easy and elegant on both iOS and OS X.

基于SnapKit, 用法简洁优雅,可运行在iOS、tvOS、macOS上自动布局库

Requirements / 使用条件

iOS 10.0+ / Mac OS X 10.12+ / tvOS 10.0+
Xcode 10.2+
Swift 5.0+

Installation / 安装

CocoaPods

pod 'ElegantSnap'

Carthage

github "ZuopanYao/ElegantSnap"

Manually / 手动安装

If you prefer not to use either of the aforementioned dependency managers, you can integrate SnapKit into your project manually.

如果您不喜欢以上管理依赖库的方式，则可以手动将 ElegantSnap 集成到项目中。

Usage / 使用

Compare with SnapKit / 与 SnapKit 比较

ElegantSnap	SnapKit
aView.make([.top()]) // aView.make([.top(nil, nil)]) // aView.make([.top(nil)])	aView.snp.makeConstraints { (make) in make.top.equalToSuperview() }
aView.make([.top(20)]) // aView.make([.top(nil, 20)])	aView.snp.makeConstraints { (make) in make.top.equalToSuperview().offset(20) }
aView.make([.top(base.snp.bottom)]) // aView.make([.top(base.snp.bottom, nil)])	aView.snp.makeConstraints { (make) in make.top.equalTo(base.snp.bottom) }
aView.make([.top(base.snp.bottom, 20)])	aView.snp.makeConstraints { (make) in make.top.equalTo(base.snp.bottom).offset(20) }
...	...
aView.make([.width()]) // aView.make([.width(nil)])	aView.snp.makeConstraints { (make) in make.top.equalToSuperview() }
aView.make([.width(200)])	aView.snp.makeConstraints { (make) in make.width.equalTo(200) }
aView.make([.width(base.snp.width)])	aView.snp.makeConstraints { (make) in make.width.equalTo(base.snp.width) }

Quick Start / 快速上手

Example 1 / 示例 1

import ElegantSnap

class ViewController: NSViewController {

    override func viewDidLoad() {

        super.viewDidLoad()

        let aView = NSView()

        view.addSubview(aView, constraints: [.top(), .leading(), .width(200), .height(400)])

        // view.addSubview(aView)

        // aView.make([.top(), .leading(), .width(200), .height(400)])

    }

}

        super.viewDidLoad()

        let aView = NSView()

        view.addSubview(aView)

        aView.snp.makeConstraints { (make) in

            make.top.equalToSuperview()

            make.leading.equalToSuperview()

            make.width.equalTo(200)

            make.height.equalTo(400)

        }

        let aView = NSView()

        view.addSubview(aView, constraints: [.top(), .leading(), .width(200), .height(400)])

        let myView = NSView()

        view.addSubview(myView, constraints: [.top(aView.snp.bottom, 20), .leading(), .width(300), .height(aView.snp.height)])

多视图排列

多个View等宽水平排列

import ElegantSnap

class ViewController: NSViewController {

    override func viewDidLoad() {

        super.viewDidLoad()

        let aView = NSView()

        aView.wantsLayer = true

        aView.layer?.backgroundColor = NSColor.red.cgColor

        let bView = NSView()

        bView.wantsLayer = true

        bView.layer?.backgroundColor = NSColor.blue.cgColor

        let cView = NSView()

        cView.wantsLayer = true

        cView.layer?.backgroundColor = NSColor.black.cgColor

        let dView = NSView()

        dView.wantsLayer = true

        dView.layer?.backgroundColor = NSColor.purple.cgColor

        view.addSubview([aView, bView, cView, dView],

                        constraints: [.height(80), .top(20)], spacing: (10, -10, 20), direction: .horizontal)

    }

}

多个View等高垂直排列

import ElegantSnap

class ViewController: NSViewController {

    override func viewDidLoad() {

        super.viewDidLoad()

        let aView = NSView()

        aView.wantsLayer = true

        aView.layer?.backgroundColor = NSColor.red.cgColor

        let bView = NSView()

        bView.wantsLayer = true

        bView.layer?.backgroundColor = NSColor.blue.cgColor

        let cView = NSView()

        cView.wantsLayer = true

        cView.layer?.backgroundColor = NSColor.black.cgColor

        let dView = NSView()

        dView.wantsLayer = true

        dView.layer?.backgroundColor = NSColor.purple.cgColor

        view.addSubview([aView, bView, cView, dView],

                        constraints: [.width(80), .leading(20)], spacing: (10, -10, 20), direction: .vertical)

    }

}
