如何在iOS上显示gauge / SpeedView (Xcode)

platform :ios, '9.0'
use_frameworks!

target 'YourProjectName' do
  pod 'GaugeKit'
end

import UIKit
import GaugeKit

class GaugeView: UIView {
    private var gaugeView: Gauge!

    override init(frame: CGRect) {
        super.init(frame: frame)
        setupGaugeView()
    }

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
        setupGaugeView()
    }

    private func setupGaugeView() {
        gaugeView = Gauge(frame: bounds)
        addSubview(gaugeView)
    }

    // 在这里可以设置gauge的属性，如最小值、最大值、当前值、颜色等
    func configureGauge() {
        gaugeView.minValue = 0
        gaugeView.maxValue = 100
        gaugeView.value = 50
        gaugeView.gaugeColor = .blue
    }
}

import UIKit

class ViewController: UIViewController {
    private var gaugeView: GaugeView!

    override func viewDidLoad() {
        super.viewDidLoad()
        setupGaugeView()
    }

    private func setupGaugeView() {
        gaugeView = GaugeView(frame: CGRect(x: 0, y: 0, width: 200, height: 200))
        gaugeView.center = view.center
        view.addSubview(gaugeView)
        gaugeView.configureGauge()
    }
}
