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:)
