Introduction

Welcome to the documentation for jpfpsstatus – a framework for tracking the status of fingerprint scanners in an iOS app. In this document, you will find all the information needed to integrate and utilize the jpfpsstatus framework seamlessly.

Installation

To install jpfpsstatus, you can use Cocoapods by adding the following line to your Podfile:


pod 'jpfpsstatus'

Functionality

Checking Fingerprint Scanner Availability

The isFingerprintScannerAvailable method can be used to determine if a fingerprint scanner is available on the device.


import jpfpsstatus

if JPFPStatus.isFingerprintScannerAvailable() {
    print("Fingerprint scanner is available.")
} else {
    print("Fingerprint scanner is not available.")
}

Getting the Fingerprint Scanner Status

You can use the getFingerprintScannerStatus method to check the current status of the fingerprint scanner. The returned status can be one of the following:

  • available: The fingerprint scanner is available and ready to be used.
  • disabled: The fingerprint scanner is disabled by the user.
  • notEnrolled: The user has not enrolled any fingerprint on the device.

import jpfpsstatus

let status = JPFPStatus.getFingerprintScannerStatus()

switch status {
case .available:
    print("Fingerprint scanner is available.")
case .disabled:
    print("Fingerprint scanner is disabled.")
case .notEnrolled:
    print("No fingerprints enrolled.")
}

Usage

Handling Fingerprint Scanner Status Change

You can implement the JPFPStatusDelegate protocol to receive notifications when the availability or status of the fingerprint scanner changes.


import jpfpsstatus

class MyFPStatusDelegate: JPFPStatusDelegate {
    func fingerprintScannerAvailabilityDidChange(available: Bool) {
        if available {
            print("Fingerprint scanner became available.")
        } else {
            print("Fingerprint scanner became unavailable.")
        }
    }
    
    func fingerprintScannerStatusDidChange(status: JPFPStatus.Status) {
        switch status {
        case .available:
            print("Fingerprint scanner status changed to 'available'.")
        case .disabled:
            print("Fingerprint scanner status changed to 'disabled'.")
        case .notEnrolled:
            print("Fingerprint scanner status changed to 'not enrolled'.")
        }
    }
}

// Set the delegate
JPFPStatus.delegate = MyFPStatusDelegate()

Conclusion

Congratulations! You have successfully integrated the jpfpsstatus framework into your iOS app. You can now easily check the availability and status of the fingerprint scanner, and handle any changes using the provided delegate methods.
