RSPizzaGraphView

This library provides a nice pizza graph view. it was made for developers who wants a better UI for their apps!

Installation

From CocoaPods

RSPizzaGraphView is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod "RSPizzaGraphView"

Manually

Copy the source file RSPizzaGraphView into your project.

Usage

RSPizzaGraphView is a UIView. So, you can create a UIView in the InterfaceBuilder and use it as an @IBOutlet, or you can create it manually. If you wanna use as an @IBOutlet, does not forget to set RSPizzaGraphView as the Custom Class of your UIView in the Interface Builder.

You need to have some values and colors in order to configure your graph. You will use the RSPizzaGraph class. You can configure the values of graph like this code, for example:

     let graphs = [RSPizzaGraph(value: 50, color: UIColor.red),
                  RSPizzaGraph(value: 15, color: UIColor.blue),
                  RSPizzaGraph(value: 23, color: UIColor.yellow),
                  RSPizzaGraph(value: 30, color: UIColor.black),
                  RSPizzaGraph(value: 20, color: UIColor.darkGray)]

The size of each slice will be calculated according the value. You can choose any color you want. Choose the nice ones! :)

You just need to call one function to configure the RSPizzaGraphView. This function have three required parameters. The others are optionals. Assuming you already have a initialized RSPizzaGraphView, you can call the function like this code below:

    pizzaGraphView.configureGraph(borderWidth: 150, 
    graphs: graphs, 
    animation: .circular, 
    shouldShowText: true, 
    font: UIFont.systemFont(ofSize: 15), 
    textColor: UIColor.white, 
    unityText: "pt")

• borderWidth: While the width of the view is the width of all RSPizzaGraphView, the border width is the width of the colored border.
• graphs: The array of RSPizzaGraph, like explained above.
• animation: The type of the animation. It is a enum called RSPizzaGraphAnimation. Can be .circular or .sliceFading.
• shouldShowText: It is a boolean that defines if the pizza graph should show the number values over the graph. The default value is false.
• font: The font used in the texts. If shouldShowText is false, it will be useless. The default value is UIFont.systemFont(ofSize: 12)
• textColor: The text color of texts. If shouldShowText is false, it will be useless. The default value is UIColor.black.
• unityText: This text will be showed together the values, in order to define its unity, if necessary. The default is "".

The parameters borderWidth, graphs and animation are required. The other ones are optionals.
