Installation
You can install DYPieChartView using CocoaPods. Simply add the following line to your Podfile:
pod 'DYPieChartView'
Then, run pod install in your terminal to install the library.
Usage
To get started with DYPieChartView, follow these steps:
- Create an instance of DYPieChartConfiguration to set the chart’s appearance:
let configuration = DYPieChartConfiguration()
You can customize the appearance of the pie chart by modifying properties of the configuration object.
- Create an instance of DYPieChartView:
let pieChartView = DYPieChartView(frame: CGRect(x: 0, y: 0, width: 200, height: 200), configuration: configuration)
Make sure to set the frame size according to your needs.
- Set the data for the chart:
let data = ["Slice 1": 25, "Slice 2": 35, "Slice 3": 40]
- Assign the data to the pie chart view:
pieChartView.data = data
This will display the pie chart with the specified data.
- Optional: Implement the delegate methods for interactivity:
class MyViewController: UIViewController, DYPieChartViewDelegate {
// Implement the delegate methods here
}
By conforming to the DYPieChartViewDelegate protocol, you can handle events such as tapping on slices or animating the chart.
Example
Here’s an example of how to use DYPieChartView:
// Import the library
import DYPieChartView
class MyViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Create a configuration object
let configuration = DYPieChartConfiguration()
// Create a pie chart view with the configuration
let pieChartView = DYPieChartView(frame: CGRect(x: 0, y: 0, width: 200, height: 200), configuration: configuration)
// Set the data for the chart
let data = ["Slice 1": 25, "Slice 2": 35, "Slice 3": 40]
pieChartView.data = data
// Add the pie chart view to the view hierarchy
self.view.addSubview(pieChartView)
}
}
