[SWIFT] Implement ProgressBar using library

Introduction

I decided to introduce a Progress Bar to tell the count app currently under development how much it is to reach the goal. In this article, I will output what I tried at that time.

Library used

・ MBCircularProgressBar →https://github.com/MatiBot/MBCircularProgressBar

Install using CocoaPods

Install SwiftConfettiView using CocoaPods.

pod "MBCircularProgressBar"

Enter the above in the Podfile and pod install.

Place parts on Storyboard

coding

python

    var number: Float = 0
    var paersent: Float!
    var targetNumber: Float!
    @IBOutlet weak var targetNumberTextField: UITextField!
    @IBOutlet weak var countNumberLabel: UILabel!
    @IBOutlet weak var progressView: MBCircularProgressBarView!

Declare variables and associate parts.

 @IBAction func countButton(_ sender: Any) {
        //Get the target number of times
        targetNumber = Float(targetNumberTextField.text!)
        //Add 1 to number
        number += 1
        //Display the number obtained by adding 1 to number
        countNumberLabel.text = "\(number)"
        //Calculate percentage
        paersent = number / targetNumber * 100
        //Show percentage
        progressView.value = CGFloat(paersent)
    }

Processing when the countButton is pressed.

    @IBAction func resetButton(_ sender: Any)
        number = 0
        progressView.value = CGFloat(number)
    }

Processing when the resetButton is pressed.

Summary

This time, we set a target number of times and visualized how much it was left as a percentage. The library can also customize bar colors and more. Please refer to the following URL for customization.
