🔫 Usage

import JustLayout

Visually

func visually() {
    view.layout(
        100,
        |-topView-| ~ 80,
        8,
        |-centerView-(>=100)-| ~ 80,
        "",
        |bottomView| ~ 80,
        0
    )
}

Chainable

func chainable() {
    centerView.centerInContainer().width(100).aspectratio(followHeight: 100%)
    topView.left(centerView, -20).top(centerView, -20).size(centerView)
    bottomView.left(centerView, 20).top(centerView, 20).size(centerView)
}

Operator-Based

func operatorBased() {
    bottomView.centerXAttribute == view.centerXAttribute
    bottomView.centerYAttribute == view.centerYAttribute
    bottomView.widthAttribute == 80
    bottomView.heightAttribute == bottomView.widthAttribute

    centerView.rightAttribute == bottomView.centerXAttribute
    centerView.topAttribute == bottomView.centerYAttribute
    centerView.widthAttribute == bottomView.widthAttribute
    centerView.heightAttribute == bottomView.heightAttribute

    topView.leftAttribute == centerView.rightAttribute
    topView.topAttribute == centerView.topAttribute
    topView.widthAttribute == 50 % centerView.widthAttribute
    topView.heightAttribute == centerView.heightAttribute
}

The Operator-Based layout is now chainable after version 1.4.0. For example:

someView.following(leftView).below(topView).size(centerView)

someView.leftAttribute == leftView.rightAttribute
someView.topAttribute == topView.bottomAttribute
someView.widthAttribute == centerView.widthAttribute
someView.heightAttribute == centerView.heightAttribute

DSL

After version 1.5.0 you can now use the JustLayoutDSL:

centerView.just.centerInContainer().width(100).aspectratio(100%)
topView.just.left(centerView, -20).top(centerView, -20).size(centerView)
bottomView.just.left(centerView, 20).top(centerView, 20).size(centerView)

Important

Please add pod 'JustLayout/DSL' to your `Podfile first.
