An iOS swift Polygon UI View component
Polygon_iOS_API
an iOS swift Polygon UI View component.
Development Target: iOS 9
Android version API: https://github.com/xattacker/Polygon_Android_API
present a custom defined polygon view:
The API could load data from code for json file(json parsing by ObjectMapper https://github.com/Hearst-DD/ObjectMapper)
and supports event callback
Installation
Cocoapods
PolygonAPI can be added to your project using CocoaPods 0.36 or later by adding the following line to your Podfile:
pod 'ObjectMapper'
pod 'PolygonAPI'
Swift Package Manager
To add PolygonAPI to a Swift Package Manager based project, add:
.package(url: "https://github.com/xattacker/Polygon_iOS_API.git", .upToNextMajor(from: "1.0.1")),
.package(url: "https://github.com/tristanhimmelman/ObjectMapper.git", .upToNextMajor(from: "4.1.0")),
to your Package.swift files dependencies array.
How to use:
import PolygonAPI
var polygonView: UIPolygonView!
// load region map from json
if let path = Bundle.main.path(forResource: "region", ofType: "json")
{
do
{
// load map resource from json file
let json = try String(contentsOfFile: path)
if !json.isEmpty,
let map = PolygonMap(JSONString: json)
{
self.polygonView.loadMap(map)
}
}
catch
{
}
}
// you could also add map region by code:
let region = PolygonRegion()
region.regionColor = UIColor.brown
region.regionId = "north"
region.titleInfo.title = "北部"
region.addPoint(CGPoint(x: 167, y: 103))
region.addPoint(CGPoint(x: 194, y: 142))
region.addPoint(CGPoint(x: 251, y: 170))
region.addPoint(CGPoint(x: 306, y: 173))
region.addPoint(CGPoint(x: 322, y: 162))
region.addPoint(CGPoint(x: 314, y: 81))
region.addPoint(CGPoint(x: 338, y: 56))
region.addPoint(CGPoint(x: 330, y: 32))
region.addPoint(CGPoint(x: 291, y: 19))
region.addPoint(CGPoint(x: 269, y: 2))
region.addPoint(CGPoint(x: 254, y: 30))
region.addPoint(CGPoint(x: 192, y: 49))
self.polygonView.addRegion(region)
// the API provides delegate to catch some events
extension ViewController: UIPolygonViewDelegate
{
func onRegionClicked(region: PolygonRegion)
{
// click region area event callback
}
func onRegionMarkClicked(mark: RegionMark, region: PolygonRegion)
{
// click mark event callback
}
}
