license |
Stores the license used in DynamsoftBarcodeReader. |
initWithLicense |
Initializes DynamsoftBarcodeReader with a license. |
outputLicenseToString |
Outputs the license content as an encrypted string from the license server to be used for offline license verification. |
initLicenseFromDLS |
Initializes the barcode reader license and connects to the specified server for online verification. |
initWithLicenseFromServer |
Initialize license and connect to the specified server for online verification. |
A property that stores the license.
@property (nonatomic, nonnull) NSString* license;
Initializes DynamsoftBarcodeReader with a license.
- (instancetype _Nonnull)initWithLicense:(NSString* _Nonnull)license;
Parameters
[in] license
The license key.
Return Value
The instance of DynamsoftBarcodeReader.
Code Snippet
>- Objective-C >- Swift > >1. ```objc [DynamsoftBarcodeReader initLicense:@"Put your license here" verificationDelegate: self]; - (void)DBRLicenseVerificationCallback:(bool)isSuccess error:(NSError *)error{ } ``` 2. ```swift DynamsoftBarcodeReader.initLicense("Put your license here", verificationDelegate: self) func dbrLicenseVerificationCallback(_ isSuccess: Bool, error: Error?) { } ```Output the license content as an encrypted string from the license server to be used for offline license verification.
- (NSString *_Nullable)outputLicenseToString:(NSError* _Nullable * _Nullable)error;
Parameters
[in,out] error
Input a pointer to an error object. If an error occurs, this pointer is set to an actual error object containing the error information. You may specify nil for this parameter if you do not want the error information.
Return Value
The output string which stores the contents of license.
Code Snippet
>- Objective-C >- Swift > >1. ```objc DynamsoftBarcodeReader *barcodeReader; barcodeReader = [[DynamsoftBarcodeReader alloc] initWithLicenseFromServer:@"" licenseKey:@"C087****" verificationDelegate:self]; NSError __autoreleasing * _Nullable error; [barcodeReader outputLicenseToString:&error]; ``` 2. ```swift let error: NSError? = NSError() let barcodeReader = DynamsoftBarcodeReader.init(licenseFromServer: "", licenseKey: "C087****", verificationDelegate: self) let licenseString = try? barcodeReader.outputLicenseToString() ```Initializes the license and connects to the specified server for online verification.
- (instancetype _Nonnull)initWithLicenseFromServer:(NSString* _Nullable)licenseSeServer licenseKey:(NSString* _Nonnull)licenseKey verificationDelegate:(id _Nullable)connectionDelegate;
Parameters
[in] licenseSeServer
The name/IP of the license server.
[in] licenseKey
The license key.
[in,out] connectionDelegate
The delegate to handle callback when license server returns.
Return Value
The instance of DynamsoftBarcodeReader.
Code Snippet
>- Objective-C >- Swift > >1. ```objc DynamsoftBarcodeReader *barcodeReader; barcodeReader = [[DynamsoftBarcodeReader alloc] initWithLicenseFromServer:@"" licenseKey:@"C087****" verificationDelegate:self]; - (void)licenseVerificationCallback:(bool)isSuccess error:(NSError * _Nullable)error { NSNumber* boolNumber = [NSNumber numberWithBool:isSuccess]; dispatch_async(dispatch_get_main_queue(), ^{ [self->verificationReceiver performSelector:self->verificationCallback withObject:boolNumber withObject:error]; }); } ``` 2. ```swift let barcodeReader = DynamsoftBarcodeReader(licenseFromServer: "", licenseKey: "C087****", verificationDelegate: self) func licenseVerificationCallback(_ isSuccess: Bool, error: Error?) { let boolNumber = NSNumber(value: isSuccess) DispatchQueue.main.async{ self.verificationReceiver?.perform(self.verificationCallback!, with: boolNumber, with: error) } } ```Initializes the barcode reader license and connects to the specified server for online verification.
- (instancetype _Nonnull)initLicenseFromDLS:(iDMDLSConnectionParameters* _Nullable)dlsConnectionParameters verificationDelegate:(id _Nullable)connectionDelegate;
Parameters
[in] dlsConnectionParameters
The struct DMDLSConnectionParameters with customized settings.
[in,out] connectionDelegate
The delegate to handle callback when license server returns.
Return Value
The instance of DynamsoftBarcodeReader.
