Progress Manager

A manager that receives a UILabel and a UIProgressView and updates their status accordingly to informations set on Progress Info

Ideal for token generation based on time (TOTP)

---

Basic Usage

You can set the label and progressView you want to update along with the necessary info

let progressInfo = ProgressInfo(text: "228538", startTime: Date(), timeleft: 10.0, maxTime: 10.0)
let progressManager = ProgressManager(progressInfo: progressInfo, label: label, progressView: progressView)
progressManager.start()

Progress Info

ProgressInfo is the model that defines the information necessary for ProgressManager

struct ProgressInfo {
    let text: String
    let startTime: Date
    let timeleft: Double
    let maxTime: Double
}

In this model you define:

• text is used to update the label
• startTime works together with timeleft. The timeleft property is the amount of time (in seconds) left to finish the progress view in relation to startTime
• maxTime is maximum total time (in seconds) of the progress view

NOTE: If timeleft is bigger than maxTime or less than 0, the progress manager won't function properly.

Personalizing

You can perfome some personalizations, such as:

• direction: defines if the bar progress is increasing or decreasing;
• smoothness: defines how smooth the progress bar will increase or decrease;
• shouldRestartAutomatically: flag to indicate if the progress bar should restart automatically after is finished (a loop).

progressManager.smoothness = .high
progressManager.direction = .increasing
progressManager.shouldRestartAutomatically = true

IMPORTANT

If shouldRestartAutomatically is set as true, is important that you set the delegate for the manager, otherwise it will NOT work.

progressManager.delegate = self

Then, use the ProgressManagerDelegate protocol method progressInfo(forProgressManager:) to update the new ProgressInfo

func progressInfo(forProgressManager progressManager: ProgressManager) -> ProgressInfo {
    return ProgressInfo(text: "234534", startTime: Date(), timeleft: 9.0, maxTime: 10.0)
}

OR

Your can restart the progressView by will using

progressManager.restart(withInfo:)
