Getting results

This page covers the description of how to get various kinds of results

Text Results

If you know exactly what text data are needed, the fastest way to get information is to use special functions.

Getting values

Getting values of text fields indicating fieldType:

Swift

// Get full name
let surnameAndGivenNames = result.getTextFieldValueByType(fieldType: .ft_Surname_And_Given_Names)
// Get date of birth
let dateOfBirth = result.getTextFieldValueByType(fieldType: .ft_Date_of_Birth)
// Get document number
let documentNumber = result.getTextFieldValueByType(fieldType: .ft_Document_Number)

Objective-C

// Get full name
NSString *surnameAndGivenNames = [resultInstance getTextFieldValueByType:RGLFieldTypeFt_Surname_And_Given_Names];
// Get date of birth
NSString *dateOfBirth = [resultInstance getTextFieldValueByType:RGLFieldTypeFt_Date_of_Birth];
// Get document number
NSString *documentNumber = [resultInstance getTextFieldValueByType:RGLFieldTypeFt_Document_Number];

Getting values of text fields indicating fieldType, lcid:

Swift

// Get full name
let surnameAndGivenNames = result.getTextFieldValueByType(fieldType: .ft_Surname_And_Given_Names, lcid: .belarusian)
// Get place of birth
let placeOfBirth = result.getTextFieldValueByType(fieldType: .ft_Place_of_Birth, lcid: .germanGermany)

Objective-C

// Get full name
NSString *surnameAndGivenNames = [result getTextFieldValueByType:RGLFieldTypeFt_Surname_And_Given_Names lcid:RGLLCIDBelarusian];
// Get place of birth
NSString *placeOfBirth = [result getTextFieldValueByType:RGLFieldTypeFt_Place_of_Birth lcid:RGLLCIDGermanGermany];

Getting values of text fields indicating fieldType, lcid, source:

Swift

// Get full name
let surnameAndGivenNames = result.getTextFieldValueByType(fieldType: .ft_Surname_And_Given_Names, lcid: .belarusian, source: .visualOCRExtended)
// Get address
let address = result.getTextFieldValueByType(fieldType: .ft_Address, lcid: .latin, source: .barCodesTextData)

Objective-C

// Get full name
NSString *surnameAndGivenNames = [result getTextFieldValueByType:RGLFieldTypeFt_Surname_And_Given_Names lcid:RGLLCIDBelarusian source:RGLResultTypeVisualOCRExtended];
// Get address
NSString *address = [result getTextFieldValueByType:RGLFieldTypeFt_Address lcid:RGLLCIDLatin source:RGLResultTypeBarCodesTextData];

Getting values of text fields indicating fieldType, lcid, source, original:

Swift

// Get surname
let surname = result.getTextFieldValueByType(fieldType: .ft_Surname, lcid: .belarusian, source: .visualOCRExtended, original: true)
// Get address
let address = result.getTextFieldValueByType(fieldType: .ft_Address, lcid: .latin, source: .barCodesTextData, original: true)

Objective-C

// Get surname
NSString *surname = [result getTextFieldValueByType:RGLFieldTypeFt_Surname lcid:RGLLCIDBelarusian source:RGLResultTypeVisualOCRExtended original:YES];
// Get address
NSString *address = [result getTextFieldValueByType:RGLFieldTypeFt_Address lcid:RGLLCIDLatin source:RGLResultTypeBarCodesTextData original:YES];

Getting values of text fields indicating fieldType, source:

Swift

// Get surname
let surname = result.getTextFieldValueByType(fieldType: .ft_Surname, source: .visualOCRExtended)

Objective-C

// Get surname
NSString *surname = [result getTextFieldValueByType:RGLFieldTypeFt_Surname source:RGLResultTypeVisualOCRExtended];

Getting values of text fields indicating fieldType, source, original:

Swift

// Get surname
let surname = result.getTextFieldValueByType(fieldType: .ft_Surname, source: .visualOCRExtended, original: true)

Objective-C

// Get surname
NSString *surname = [result getTextFieldValueByType:RGLFieldTypeFt_Surname source:RGLResultTypeVisualOCRExtended original:YES];

Getting values of text fields indicating fieldType, original:

Swift

// Get surname
let surname = result.getTextFieldValueByType(fieldType: .ft_Surname, original: true)

Objective-C

// Get surname
NSString *surname = [result getTextFieldValueByType:RGLFieldTypeFt_Surname original:YES];

You can also go through all instances of text fields and obtain the desired information, e.g.:

Swift

for textField in result.textResult.fields {
    guard let value = result.getTextFieldValueByType(fieldType: textField.fieldType, lcid: textField.lcid) else { continue }
    print("fieldName: \(textField.fieldName), value: \(value)")
}

Objective-C

for (RGLDocumentReaderTextField *textField in result.textResult.fields) {
    NSString *value = [result getTextFieldValueByType:textField.fieldType lcid:textField.lcid];
    NSLog(@"fieldName: %@, value: %@", textField.fieldName, value);
}

let address = result.getTextFieldByType(fieldType: .ft_Address)

Objective-C

// Get a surname instance
RGLDocumentReaderTextField *surname = [result getTextFieldByType:RGLFieldTypeFt_Surname];
