Usage
Generating Barcodes
To generate a PDF417 barcode, follow these steps:
- Create an instance of the
PPpdf417RecognizerSettings
class. - Set the desired properties for the barcode generation, such as data, error correction level, and more.
- Create an instance of the
PPpdf417Recognizer
class. - Call the
recognizer.recognize()
method to generate the barcode.
Scanning Barcodes
To scan a PDF417 barcode, follow these steps:
- Create an instance of the
PPpdf417RecognizerSettings
class. - Set the desired properties for the barcode scanning, such as the scanning region, expected barcode types, and more.
- Create an instance of the
PPpdf417Recognizer
class. - Call the
recognizer.recognize()
method to start the barcode scanning process.
Example Code
Here’s an example code snippet for generating a PDF417 barcode:
// Import the necessary dependencies
#import <PPpdf417/PPpdf417.h>
// Create settings for the barcode generation
PPpdf417RecognizerSettings *settings = [[PPpdf417RecognizerSettings alloc] initWithData:@"Hello World"];
// Create a recognizer instance
PPpdf417Recognizer *recognizer = [[PPpdf417Recognizer alloc] initWithSettings:settings];
// Generate the barcode
UIImage *barcodeImage = [recognizer recognize];
And here’s an example code snippet for scanning a PDF417 barcode:
// Import the necessary dependencies
#import <PPpdf417/PPpdf417.h>
// Create settings for the barcode scanning
PPpdf417RecognizerSettings *settings = [[PPpdf417RecognizerSettings alloc] init];
// Set the desired properties for scanning
// settings.region = ...;
// settings.expectedBarcodeTypes = ...;
// Create a recognizer instance
PPpdf417Recognizer *recognizer = [[PPpdf417Recognizer alloc] initWithSettings:settings];
// Start the barcode scanning process
[recognizer recognize];
Troubleshooting
If you’re experiencing any issues or errors while using the PPpdf417 library, please try the following:
Issue 1: Barcode not generating/scanning
Make sure you have provided the correct data and settings for barcode generation/scanning. Double-check the properties you have set in the PPpdf417RecognizerSettings
class.
Issue 2: Library not found
If you’re using CocoaPods, ensure that you have run the pod install
command and that you have correctly added the PPpdf417 library to your Xcode workspace.
Conclusion
Congratulations! You are now equipped with the knowledge to use the PPpdf417 library for generating and scanning PDF417 barcodes. Feel free to explore the library further and customize its functionality to suit your needs.
