Requirements

• Xcode 9
• iOS 9.x+
• Swift 4

Be sure to read all instructions carefully.

Installing with CocoaPods

pod 'SMDiagramViewSwift', '~> 1.0'

Usage

Add a UIView instance in your .storyboard or .xib, set SMDiagramView class, connect IBOutlet and add DataSource

import SMDiagramViewSwift

class ViewController: UIViewController, SMDiagramViewDataSource {
    
    let dataSource = [1, 2, 3, 4, 5]
    
    @IBOutlet weak var diagramView: SMDiagramView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        diagramView.dataSource = self
    }
}

Setup SMDiagramView if need

    override func viewDidLoad() {
        super.viewDidLoad()
        
        diagramView.dataSource = self
        diagramView.minProportion = 0.1
        diagramView.diagramViewMode = .arc // or .segment
        diagramView.diagramOffset = .zero
        diagramView.radiusOfSegments = 80.0
        diagramView.radiusOfViews = 130.0
        diagramView.arcWidth = 6.0 //Ignoring for SMDiagramViewMode.segment
        diagramView.startAngle = -.pi/2
        diagramView.endAngle = 2.0 * .pi - .pi/2.0
        diagramView.colorOfSegments = .black
        diagramView.viewsOffset = .zero
        diagramView.separatorWidh = 1.0
        public var separatorColor = .white
}

DataSource functions

    //Required
    func numberOfSegmentsIn(diagramView: SMDiagramView) -> Int {
        return dataSource.count
    }
    
    //Optional
    func diagramView(_ diagramView: SMDiagramView, proportionForSegmentAtIndex index: NSInteger) -> CGFloat {
        return CGFloat(1/dataSource.count)
    }
    func diagramView(_ diagramView: SMDiagramView, colorForSegmentAtIndex index: NSInteger, angle: CGFloat) -> UIColor? {
        return .black
    }
    func diagramView(_ diagramView: SMDiagramView, viewForSegmentAtIndex index: NSInteger, colorOfSegment color:UIColor?, angle: CGFloat) -> UIView? {
        return UIView()
    }
    func diagramView(_ diagramView: SMDiagramView, offsetForView view: UIView?, atIndex index: NSInteger, angle: CGFloat) -> CGPoint {
        return .zero
    }
    func diagramView(_ diagramView: SMDiagramView, radiusForView view: UIView?, atIndex index: NSInteger, radiusOfSegment radius: CGFloat, angle: CGFloat) -> CGFloat {
        return 130.0
    }
    func diagramView(_ diagramView: SMDiagramView, radiusForSegmentAtIndex index: NSInteger, proportion: CGFloat, angle: CGFloat) -> CGFloat {
        return 80.0
    }
    func diagramView(_ diagramView: SMDiagramView, lineWidthForSegmentAtIndex index: NSInteger, angle: CGFloat) -> CGFloat {
        //not called for SMDiagramViewModeSegment
        return 6.0
    }
