Introduction:

Welcome to the documentation page for FingerprintCapture, an API for capturing fingerprints on iOS. This library provides a simple and easy-to-use interface for integrating fingerprint capture functionality into your iOS applications.

Getting Started:

Installation:

To use the FingerprintCapture library, you need to install it using CocoaPods. If you haven’t already, install CocoaPods by running the following command in your terminal:



$ sudo gem install cocoapods

Next, create a Podfile in your project’s root directory by running the following command:


$ pod init

Inside the Podfile, add the following line:



pod 'FingerprintCapture'

Save the Podfile and then run the following command to install the FingerprintCapture library:


$ pod install

Finally, open your project workspace by running:


$ open YourProject.xcworkspace

Usage:

To use FingerprintCapture in your iOS application, follow these steps:

  1. Import the FingerprintCapture module:



    2. import FingerprintCapture

  2. Create an instance of the FingerprintCapture class:



    3. let fingerprintCapture = FingerprintCapture()

  3. Request permission for fingerprint capture:



    4. fingerprintCapture.requestPermission { (success, error) in
    if success {
    // Permission granted, proceed with fingerprint capture
    } else {
    // Permission denied, handle error
    }
    }

  4. Display fingerprint capture UI:



    5. fingerprintCapture.presentCaptureUI(on: self) { (result, error) in
    if let fingerprintImage = result {
    // Fingerprint captured successfully, handle the image
    } else {
    // Error occurred during fingerprint capture, handle error
    }
    }

Reference:

The FingerprintCapture library provides the following classes:

FingerprintCapture:

The main class of the FingerprintCapture library. It provides methods for requesting permission and capturing fingerprints.

requestPermission:

A method used to request permission for capturing fingerprints. It takes a completion handler that is called with a success flag and an optional error if permission is denied or an error occurs.

presentCaptureUI:

A method used to display the fingerprint capture UI. It takes a view controller on which to present the UI, and a completion handler that is called with an optional fingerprint image if capture is successful, or an error if an error occurs.

Troubleshooting:

Unable to Request Permission:

If you are unable to request permission for fingerprint capture, make sure you have the necessary entitlements configured in your project and that the device supports fingerprint capture.

Capture Fails:

If capturing a fingerprint fails, ensure that the device has a valid fingerprint enrolled and that the user places their finger correctly on the fingerprint sensor.

Conclusion:

Congratulations! You have successfully integrated the FingerprintCapture library into your iOS application. You can now enable your users to capture fingerprints with ease.
