## Attributes

| Attributes | Type | Description |
| ---------- | ---- | ----------- |
| [`rows`](#rows) | *NSInteger* | The number of rows of the Aztec barcode. |
| [`columns`](#columns) | *NSInteger* | The number of columns in the Aztec barcode. |
| [`layerNumber`](#layernumber) | *NSInteger* | Specifies the layer number of the Aztec barcode. A negative number (-1, -2, -3, -4) specifies a compact Aztec code. A positive number (1, 2, .. 32) specifies a normal (full-range) Aztec code. |

### rows

### layerNumber

Returns the layer number of the Aztec barcode. A negative number (-1, -2, -3, -4) specifies a compact Aztec code, while a positive number (1, 2, .. 32) specifies a normal (full-range) Aztec code. The layer number determines the complexity and capacity of the Aztec barcode.
