Usage

There is a container view S which width is 100 and height is wrap to all subviews height. there are four subviews A,B,C,D arranged from top to bottom.
Subview A's left margin is 20% width of S, right margin is 30% width of S, height is equal to width of A.
Subview B's left margin is 40, width is filled in to residual width of S,height is 40.
Subview C's width is filled in to S, height is 40.
Subview D's right margin is 20, width is 50% width of S, height is 40

    let S = TGLinearLayout(.vert)
    S.tg_vspace = 10
    S.tg_width.equal(100)
    S.tg_height.equal(.wrap)
    //you can use S.tg_size(width:100, height:.wrap) to instead
    
    let A = UIView()
    A.tg_left.equal(20%)
    A.tg_right.equal(30%)
    A.tg_height.equal(A.tg_width)
    S.addSubview(A)
    
    let B = UIView()
    B.tg_left.equal(40)
    B.tg_width.equal(.fill)
    B.tg_height.equal(40)
    S.addSubview(B)
    
    let C = UIView()
    C.tg_width.equal(.fill)
    C.tg_height.equal(40)
    S.addSubview(C)
    
    let D = UIView()
    D.tg_right.equal(20)
    D.tg_width.equal(50%)
    D.tg_height.equal(40)
    S.addSubview(D)

TangramKit has override operators: ~=、>=、<=、+=、-=、*=、/= to implement equal、max、min、add、offset、multiply methods of TGLayoutSize and TGLayoutPos class, so you can instead to:

let S = TGLinearLayout(.vert)
   S.tg_vspace = 10
   S.tg_width ~=100
   S.tg_height ~=.wrap
   
   let A = UIView()
   A.tg_left ~=20%
   A.tg_right ~=30%
   A.tg_height ~=A.tg_width
   S.addSubview(A)
   
   let B = UIView()
   B.tg_left ~=40
   B.tg_width ~=.fill
   B.tg_height ~=40
   S.addSubview(B)
   
   let C = UIView()
   C.tg_width ~=.fill
   C.tg_height ~=40
   S.addSubview(C)
   
   let D = UIView()
   D.tg_right ~=20
   D.tg_width ~=50%
   D.tg_height ~=40
   S.addSubview(D)

Architecture

TGLayoutPos

TGLayoutPos is represent to the position of a view. UIView provides six extension variables:tg_left, tg_top, tg_bottom, tg_right, tg_centerX, tg_centerY to set view's margin or space distance between self and others.

TGLayoutSize

TGLayoutSize is represent to the size of a view. UIView provides two extension variables:tg_width,tg_height to set view's width and height dimension. there are three special TGLayoutSize const object: .wrap, .fill, .average mean: wrap all subviews size, fill in to superview's residual size, average the superview's size.

TGWeight

TGWeight is used to set relative position and dimension. TangramKit override operator % to easily construct a TGWeight object. e.g 20% is equal to TGWeight(20).

TGLinearLayout

Is equivalent to: UIStackView of iOS and LinearLayout of Android.

Linear layout is a single line layout view that the subviews are arranged in sequence according to the added order（from top to bottom or from left to right). So the subviews' origin&size constraints are established by the added order. Subviews arranged in top-to-bottom order is called vertical linear layout view, and the subviews arranged in left-to-right order is called horizontal linear layout.

override func loadView() {
        
        
            super.loadView()
        
            let S = TGLinearLayout(.vert)
            S.tg_width.equal(120)
            S.tg_height.equal(.wrap)
            S.tg_vspace = 10
            
            let A = UIView()
            A.tg_left.equal(5)
            A.tg_right.equal(5)
            A.tg_width.equal(100)
            A.tg_height.equal(40)
            S.addSubview(A)
            
            let B = UIView()
            B.tg_left.equal(20)
            B.tg_width.equal(40)
            B.tg_height.equal(40)
            S.addSubview(B)
            
            let C = UIView()
            C.tg_right.equal(40)
            C.tg_width.equal(50)
            C.tg_height.equal(40)
            S.addSubview(C)
            
            let D = UIView()
            D.tg_left.equal(10)
            D.tg_right.equal(10)
            D.tg_width.equal(100)
            D.tg_height.equal(40)
            S.addSubview(D)
            
            self.view.addSubview(S)
            S.backgroundColor = .red
            A.backgroundColor = .green
            B.backgroundColor = .blue
            C.backgroundColor = .orange
            D.backgroundColor = .cyan
     }

TGRelativeLayout

Is equivalent to: AutoLayout of iOS and RelativeLayout of Android.

Relative layout is a layout view that the subviews layout and position through mutual constraints.The subviews in the relative layout are not depended to the adding order but layout and position by setting the subviews' constraints.

override func loadView() {
        
        
            super.loadView()
        
        let S = TGRelativeLayout()
        S.tg_width.equal(170).and().tg_height.equal(280)
        
        let A = UIView()
        A.tg_left.equal(20).and().tg_top.equal(20)
        A.tg_width.equal(40).and().tg_height.equal(A.tg_width)
        S.addSubview(A)
        
        let B = UIView()
        B.tg_left.equal(A.tg_centerX).and().tg_top.equal(A.tg_bottom).offset(10)
        B.tg_width.equal(60).and().tg_height.equal(A.tg_height)
        S.addSubview(B)
        
        let C = UIView()
        C.tg_left.equal(B.tg_right).offset(10)
        C.tg_bottom.equal(B.tg_bottom)
        C.tg_width.equal(40)
        C.tg_height.equal(B.tg_height, multiple:0.5)
        S.addSubview(C)
        
        let D = UIView()
        D.tg_bottom.equal(C.tg_top).offset(10)
        D.tg_right.equal(15)
        D.tg_height.equal(A.tg_height)
        D.tg_width.equal(D.tg_height)
        S.addSubview(D)
        
        let E = UIView()
        E.tg_centerY.equal(0)
        E.tg_centerX.equal(0)
        E.tg_height.equal(40)
        E.tg_width.equal(S.tg_width).add(-20)
        S.addSubview(E)
        //...F,G
        
            self.view.addSubview(S)
            S.backgroundColor = .red
            A.backgroundColor = .green
            B.backgroundColor = .blue
            C.backgroundColor = .orange
            D.backgroundColor = .cyan
            E.backgroundColor = .magenta
       }

TGFrameLayout

Is equivalent to: FrameLayout of Android.

Frame layout is a layout view that the subviews can be overlapped and gravity in a special location of the superview.The subviews' layout position&size is not depended to the adding order and establish dependency constraint with the superview. Frame layout devided the vertical orientation to top,vertical center and bottom, while horizontal orientation is devided to left,horizontal center and right. Any of the subviews is just gravity in either vertical orientation or horizontal orientation.

 override func loadView() {
        
        
        super.loadView()
        
        let S = TGFrameLayout()
        S.tg_width.equal(320)
        S.tg_height.equal(500)
        
        let A = UIView()
        A.tg_width.equal(40)
        A.tg_height.equal(40)
        S.addSubview(A)
        
        let B = UIView()
        B.tg_width.equal(40)
        B.tg_height.equal(40)
        B.tg_right.equal(0)
        S.addSubview(B)
        
        let C = UIView()
        C.tg_width.equal(40)
        C.tg_height.equal(40)
        C.tg_centerY.equal(0)
        S.addSubview(C)
        
        let D = UIView()
        D.tg_width.equal(40)
        D.tg_height.equal(40)
        D.tg_centerY.equal(0)
        D.tg_centerX.equal(0)
        S.addSubview(D)
        
        //..E，F,G
        
        self.view.addSubview(S)
        S.backgroundColor = .red
        A.backgroundColor = .green
        B.backgroundColor = .blue
        C.backgroundColor = .orange
        D.backgroundColor = .cyan
}

TGTableLayout

Is equivalent to: TableLayout of Android and table of HTML.

Table layout is a layout view that the subviews are multi-row&col arranged like a table. First you must create a rowview and add it to the table layout, then add the subview to the rowview. If the rowviews arranged in top-to-bottom order,the tableview is caled vertical table layout,in which the subviews are arranged from left to right; If the rowviews arranged in in left-to-right order,the tableview is caled horizontal table layout,in which the subviews are arranged from top to bottom.

   override func loadView() {
        
        
        super.loadView()
        
        let S = TGTableLayout(.vert)
        S.tg_height.equal(.wrap)
        S.tg_width.equal(.wrap)
        S.tg_vspace = 10
        S.tg_hspace = 10
        
        
        S.tg_addRow(size:TGLayoutSize.wrap,colSize:TGLayoutSize.wrap)
        
        let A = UIView()
        A.tg_width.equal(50)
        A.tg_height.equal(40)
        S.addSubview(A)
        
        let B = UIView()
        B.tg_width.equal(100)
        B.tg_height.equal(40)
        S.addSubview(B)
        
        let C = UIView()
        C.tg_width.equal(30)
        C.tg_height.equal(40)
        S.addSubview(C)
        
        S.tg_addRow(size:TGLayoutSize.wrap,colSize:TGLayoutSize.wrap)
        
        let D = UIView()
        D.tg_width.equal(200)
        D.tg_height.equal(40)
        S.addSubview(D)
        
        //...E,F  
        
        self.view.addSubview(S)
        S.backgroundColor = .red
        A.backgroundColor = .green
        B.backgroundColor = .blue
        C.backgroundColor = .orange
        D.backgroundColor = .cyan       
}

TGFlowLayout

Is equivalent to: flexbox of CSS3.

Flow layout is a layout view presents in multi-line that the subviews are arranged in sequence according to the added order, and when meeting with a arranging constraint it will start a new line and rearrange. The constrains mentioned here includes count constraints and size constraints. The orientation of the new line would be vertical and horizontal, so the flow layout is divided into: count constraints vertical flow layout, size constraints vertical flow layout, count constraints horizontal flow layout, size constraints horizontal flow layout. Flow layout often used in the scenes that the subviews is arranged regularly, it can be substitutive of UICollectionView to some extent. the TGFlowLayout is almost implement the flex-box function of the HTML/CSS.

   override func loadView() {
        
        
        super.loadView()
        
        let S = TGFlowLayout(.vert,arrangedCount:4)
        S.tg_height.equal(.wrap)
        S.tg_width.equal(300)
        S.tg_padding = UIEdgeInsetsMake(10,10,10,10)
        S.tg_gravity = TGGravity.horz.fill
        S.tg_space = 10
        
        for _ in 0 ..< 10
        {
            let A = UIView()
            A.tg_height.equal(A.tg_width)
            S.addSubview(A)
            
            A.backgroundColor = .green
        }
        
        self.view.addSubview(S)
        S.backgroundColor = .red
}

TGFloatLayout

Is equivalent to: float of CSS.

Float layout is a layout view that the subviews are floating gravity in the given orientations, when the size is not enough to be hold, it will automatically find the best location to gravity. float layout's conception is reference from the HTML/CSS's floating positioning technology, so the float layout can be designed in implementing irregular layout. According to the different orientation of the floating, float layout can be divided into left-right float layout and up-down float layout.

     override func loadView() {
        
        
        super.loadView()
        
        let S = TGFloatLayout(.vert)
        S.tg_height.equal(.wrap)
        S.tg_width.equal(300)
        S.tg_padding = UIEdgeInsetsMake(10,10,10,10)
        S.tg_space = 10
        
        let A = UIView()
        A.tg_width.equal(80)
        A.tg_height.equal(70)
        S.addSubview(A)
        
        let B = UIView()
        B.tg_width.equal(150)
        B.tg_height.equal(40)
        S.addSubview(B)
        
        let C = UIView()
        C.tg_width.equal(70)
        C.tg_height.equal(40)
        S.addSubview(C)
        
        let D = UIView()
        D.tg_width.equal(100)
        D.tg_height.equal(140)
        S.addSubview(D)
        
        let E = UIView()
        E.tg_width.equal(150)
        E.tg_height.equal(40)
        E.tg_reverseFloat = true
        S.addSubview(E)
        
        let F = UIView()
        F.tg_width.equal(120)
        F.tg_height.equal(60)
        S.addSubview(F)
      
        self.view.addSubview(S)
        S.backgroundColor = .red
        A.backgroundColor = .green
        B.backgroundColor = .blue
        C.backgroundColor = .orange
        D.backgroundColor = .black
        E.backgroundColor = .magenta
        F.backgroundColor = .white
}

TGPathLayout

Is unique characteristic layout view of iOS.

Path layout is a layout view that the subviews are according to a specified path curve to layout. You must provide a type of Functional equation，a coordinate and a type of distance setting to create a Path Curve than all subview are equidistance layout in the Path layout. path layout usually used to create some irregular and gorgeous UI layout.

Sample code:

override func loadView() 
{
       
   super.loadView()
   
   let S = TGPathLayout()
   S.tg_width.equal(320)
   S.tg_height.equal(320)
   S.tg_coordinateSetting.isReverse = true
   S.tg_coordinateSetting.origin = CGPoint(x: 0.5, y: 0.2) 
   S.tg_polarEquation = { 80 * (1 + cos(CGFloat($0))) } // r = a *(1 + cos(𝛉))
   
   for _ in 0 ..< 4
   {
       let A = UIView()
       A.tg_size(width:40,height:40)
       S.addSubview(A)
       
       A.backgroundColor = .green
   }

   self.view.addSubview(S)
   S.backgroundColor = .red
}

TGViewSizeClass

Is equivalent to: Size Classes of iOS.

TangramKit provided support to SizeClass in order to fit the different screen sizes of devices. You can combinate the SizeClass with any of the 6 kinds of layout views mentioned above to perfect fit the UI of all equipments.

    public func tg_fetchSizeClass(with type:TGSizeClassType, from srcType:TGSizeClassType! = nil) ->TGViewSizeClass

//all device
let rootLayout = TGLinearLayout(.vert)
        rootLayout.tg_padding = UIEdgeInsetsMake(10, 10, 10, 10);
        rootLayout.tg_vspace = 10
        rootLayout.tg_hspace = 10
        
//iPhone landscape orientation.
let lsc = rootLayout.tg_fetchSizeClass(with: .comb(.any, .compact, nil), from:.default) as! TGLinearLayoutViewSizeClass
        lsc.tg_orientation = .horz
