SMDiagramViewSwift

Meet cute and very flexibility library for iOS application for different data view in one circle diagram. The opportunity of transformation of this sample make application interactive, colorful with wow-effect.

CocoaControls

Requirements

  • Xcode 9
  • iOS 9.x+
  • Swift 4

Be sure to read all instructions carefully.

Installing with CocoaPods

use_frameworks! 

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
    }
