    Declaration

    Objective-C

    @property (readonly, nonatomic) CGRect frame;

    Declaration

    Objective-C

    @property (readonly, nonatomic, nullable) NSString *rawValue;
  • A barcode value in a user-friendly format. May omit some of the information encoded in the barcode. For example, in the case above the display value might be ‘https://www.google.com’.

May include the supplement value.
