rows

The number of rows in the QR Code.

Objective-C
Swift

@property (nonatomic, readonly, assign) NSInteger rows;

```
var rows: Int { get }
```

columns

The number of columns in the QR Code.

Objective-C
Swift

@property (nonatomic, readonly, assign) NSInteger columns;

```
var columns: Int { get }
```

errorCorrectionLevel

Describes the error correction level of the QR Code as a DSQRCodeErrorCorrectionLevel enumeration item.

Objective-C
Swift

@property (nonatomic, readonly, assign) DSQRCodeErrorCorrectionLevel errorCorrectionLevel;

var errorCorrectionLevel: QRCodeErrorCorrectionLevel { get }

version

The version of the QR Code.

Objective-C
Swift

@property (nonatomic, readonly, assign) NSInteger version;

```
var version: Int { get }
```

model

The number of models of the QR Code.

Objective-C
Swift

@property (nonatomic, readonly, assign) NSInteger model;

```
var model: Int { get }
```

mode

Identifies the first data encoding mode used in the QR Code.

Objective-C
Swift

@property (nonatomic, readonly, assign) NSInteger mode;

```
var mode: Int { get }
```

page

The position of the particular symbol in the Structured Append format of the QR Code.

Objective-C
Swift

@property (nonatomic, readonly, assign) NSInteger page;

```
var page: Int { get }
```

totalPage

The total number of symbols to be concatenated into the Structured Append format of the QR Code.

Objective-C
Swift

@property (nonatomic, readonly, assign) NSInteger totalPage;

```
var totalPage: Int { get }
```

parityData

The parity data is obtained by XORing a byte with the ASCII/JIS values of all the original input data before division into symbol blocks. It is used for error checking and correction.

Objective-C
Swift

@property (nonatomic, readonly, assign) Byte parityData;

```
var parityData: Int { get }
```

dataMaskPattern

The data mask pattern reference for QR Code symbols.

Objective-C
Swift

@property (nonatomic, readonly, assign) NSInteger dataMaskPattern;

```
var dataMaskPattern: Int { get }
```

codewords

The codewords of the QR Code.

Objective-C
Swift

@property (nonatomic, readonly, retain) NSData *codewords;

```
var codewords: Data? { get }
```
