Usage

Init ERView

Init with ERView, and constructure DrawsInfo.

let frame = CGRect(x: 0, y: 64, width: view.frame.width, height: view.frame.height - 128)
let drawsInfo = [["type": "华为", "percent": "35%"],
                 ["type": "OPPO", "percent": "20%"],
                 ["type": "vivo", "percent": "25%"],
                 ["type": "小米", "percent": "5%"],
                 ["type": "苹果", "percent": "5%"],
                 ["type": "三星", "percent": "5%"],
                 ["type": "金立", "percent": "5%"]]
let erView = ERView(frame: frame, drawsInfo: drawsInfo)

and then, add erView to the contentView that you want to show in.

if let erView = erView {
	view.addSubview(erView)
}

there is nothing at present, you should config some properties.

Config

property	type	description
drawRule	enum	padding, fill, see below.
showShadow	bool	Graphic radian view with shadow. default true
showPercentInRadian	bool	Show the percent string in the erView, default true

erView.drawRule = .padding
erView.titleText = "2017年8月中国手机市场份额"
erView.digestLoc = .top
erView.digestKey = "type"
erView.percentKey = "percent"
erView.showShadow = false

you must invoke startDraw() method.

erView.startDraw()

Effects

showShadow: true or false

drawRule: .padding, .fill

digestLoc: top left right bottom

show3DEffect(ignore drawRule)
