安装

Swift Package

dependencies: [
    .package(url: "https://github.com/huangwenfei/Yang.git", .upToNextMajor(from: "0.0.1"))
]

Cocoapods

target '<Your Target Name>' do
    pod 'Yang'
end

例子

具体可以查看 Yang-Examples 工程。

注意点

someLayoutItem.yang.addToParent(...)
someLayoutItem.yang.removeFromParent()

addToParent 内部会自动保存 translatesAutoresizingMaskIntoConstraints 的状态。
removeFromParent 内部会重置之前保存的 translatesAutoresizingMaskIntoConstraints 的状态。

当然也可以手动设置：

parentView.addSubview(someLayoutItem)
someLayoutItem.yang.saveState()

/// some yang layout code

someLayoutItem.removeFromSuperview()
someLayoutItem.yang.resetState()

基础

let parentView = ...

let yellow = YellowView()
yellow.yang.addToParent(parentView)

#if false
yellow.yang.edge
    .equalToParent()
    .identifier("yellow-edge")
    .active()
    
#else
yellow.yang.left.equalToParent().identifier("yellow-left").offset(16).active()
yellow.yang.right.equalToParent().identifier("yellow-right").offset(-16).active()
yellow.yang.top.equalToParent().identifier("yellow-top").offset(16).active()

yellow.yang.height
    .equal(to: 50)
    .identifier("yellow-height")
    .active()
#endif

基础 - 更新

let parentView = ...

let yellow = YellowView()
yellow.yang.addToParent(parentView)

yellow.yang.left.equalToParent().identifier("yellow-left").offset(16).active()
yellow.yang.right.equalToParent().identifier("yellow-right").offset(-16).active()
yellow.yang.top.equalToParent().identifier("yellow-top").offset(16).active()

let yellowH = yellow.yang.height
    .equal(to: 50)
    .identifier("yellow-height")
    .active()

DispatchQueue.main.asyncAfter(deadline: .now() + 2) {
    yellowH.updater.offset(280).active()
    self.view.setNeedsUpdateConstraints()
}

批量

let parentView = ...

let yellow = YellowView()
yellow.yang.addToParent(parentView)

yellow.yangbatch.make { make in
    make.left.equalToParent().identifier("yellow-left").offset(46)
    make.right.equalToParent().identifier("yellow-right").offset(-46)
    make.top.equalToParent().identifier("yellow-top").offset(46)
    make.height.equal(to: 150).identifier("yellow-height")
}

批量 - 更新

let parentView = ...

let yellow = YellowView()
yellow.yang.addToParent(parentView)

yellow.yangbatch.make { make in
    make.left.equalToParent().identifier("yellow-left").offset(16)
    make.right.equalToParent().identifier("yellow-right").offset(-16)
    make.top.equalToParent().identifier("yellow-top").offset(16)
    make.height.equal(to: 50).identifier("yellow-height")
}

DispatchQueue.main.asyncAfter(deadline: .now() + 2) {
    yellow.yangbatch.remake { make in
        make.left.right
            .equalToParent()
            .offsetEdge(40)
        make.top
            .equalToParent()
            .offset(100)
        make.bottom
            .equal(to: parentView.yangbatch.bottom)
            .offsetEdge(50)
    }
}

Yang is changed according to the SnapKit.
Yang currently only supports iOS.

Installation

Swift Package

dependencies: [
    .package(url: "https://github.com/huangwenfei/Yang.git", .upToNextMajor(from: "0.0.1"))
]

Cocoapods

target '<Your Target Name>' do
    pod 'Yang'
end

Examples

Check out the Yang-Examples project.

Pay attention

someLayoutItem.yang.addToParent(...)
someLayoutItem.yang.removeFromParent()

addToParent internal will automatically save translatesAutoresizingMaskIntoConstraints state.
removeFromParent internal will reset before save translatesAutoresizingMaskIntoConstraints state.

You can also set it manually:

parentView.addSubview(someLayoutItem)
someLayoutItem.yang.saveState()

/// some yang layout code

someLayoutItem.removeFromSuperview()
someLayoutItem.yang.resetState()

Base

let parentView = ...

let yellow = YellowView()
yellow.yang.addToParent(parentView)

if false
yellow.yang.edge
    .equalToParent()
    .identifier("yellow-edge")
    .active()
    
#else
yellow.yang.left.equalToParent().identifier("yellow-left").offset(16).active()
yellow.yang.right.equalToParent().identifier("yellow-right").offset(-16).active()
yellow.yang.top.equalToParent().identifier("yellow-top").offset(16).active()

yellow.yang.height
    .equal(to: 50)
    .identifier("yellow-height")
    .active()
#endif

Base - Update

let parentView = ...

let yellow = YellowView()
yellow.yang.addToParent(parentView)

yellow.yang.left.equalToParent().identifier("yellow-left").offset(16).active()
yellow.yang.right.equalToParent().identifier("yellow-right").offset(-16).active()
yellow.yang.top.equalToParent().identifier("yellow-top").offset(16).active()

let yellowH = yellow.yang.height
    .equal(to: 50)
    .identifier("yellow-height")
    .active()

DispatchQueue.main.asyncAfter(deadline: .now() + 2) {
    yellowH.updater.offset(280).active()
    self.view.setNeedsUpdateConstraints()
}

Batch

let parentView = ...
