A flexible layout tool similar to SwiftUI syntax

FlexLayout

FlexLayout is a flexible layout tool similar to SwiftUI syntax， ConstraintLayout is the syntactic sugar of NSLayoutAnchor.

Example

To run the example project, clone the repo, and run pod install from the Example directory first.

FL.V(frame: view.bounds) {
    if #available(iOS 11.0, *) {
        FL.Space.fixed(self.view.safeAreaInsets.top)
    } else {
        FL.Space.fixed(20)
    }
    FL.Bind(userInfoContent) { rect in
        FL.H(size: rect.size) {
            FL.Space.fixed(20)
            self.avatarImgv.with(main: .fixed(60), cross: .fixed(60, offset: 0, align: .center))
            FL.Space.fixed(20)
            FL.Virtual { rect in
                FL.V(frame: rect) {
                    self.titleLabel.with(main: .fixed(30))
                    FL.Space.grow()
                    FL.Virtual { rect in
                        FL.H(frame: rect) {
                            self.linkName.with(main: .fixed(40))
                            self.linkLabel.with(main: .grow)
                        }
                    }.with(main: .fixed(20))
                }
            }.with(main: .grow, cross: .fixed(60, offset: 0, align: .center))
            FL.Space.fixed(20)
        }
    }.with(main: .fixed(100), cross: .stretch(margin: (start: 20, end: 20)))
    FL.Space.grow()
    self.bottomBar.with(main: .fixed(60), cross: .stretch(margin: (start: 20, end: 20)))
    if #available(iOS 11.0, *) {
        FL.Space.fixed(self.view.safeAreaInsets.bottom)
    } else {
        FL.Space.fixed(20)
    }
}

CL.layout(clTest) {
    clTest.centerXAnchor |== view.centerXAnchor
    clTest.centerYAnchor |== view.centerYAnchor + 100
    (clTest.heightAnchor & clTest.widthAnchor) |== 100
}
CL.layout(clTest2) {
    clTest2.heightAnchor |== clTest.widthAnchor
    clTest2.widthAnchor |== clTest.widthAnchor * 2 + 100
    clTest2.centerXAnchor |== clTest.centerXAnchor
    clTest2.bottomAnchor |== bottomBar.topAnchor
}
