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。

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)])
    }

class ViewController: NSViewController {
    
    override func 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)
    }

        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)
