### startCharsBytes

A [NSData](https://developer.apple.com/documentation/foundation/nsdata){:target="_blank"} object representing the start characters of the 1D barcode in a byte array. Start characters are often used to identify the beginning of the barcode.

```objc
@property(nonatomic, readonly, copy, nullable) NSData *startCharsBytes;
```
2. 
```swift
var startCharsBytes: Data? { get }
```

### stopCharsBytes


A [NSData](https://developer.apple.com/documentation/foundation/nsdata){:target="_blank"} object representing the stop characters of the 1D barcode in a byte array. Stop characters are often used to identify the end of the barcode.

```objc
@property(nonatomic, readonly, copy, nullable) NSData *stopCharsBytes;
```
2. 
```swift
var stopCharsBytes: Data? { get }
```

### checkDigitBytes

A [NSData](https://developer.apple.com/documentation/foundation/nsdata){:target="_blank"} object representing the check digit characters of the 1D barcode in a byte array. Check digits are used for error detection and correction in some 1D barcodes.

2. 
```swift
var checkDigitBytes: Data? { get }
```

### startPatternRange

A [UIFloatRange](https://developer.apple.com/documentation/uikit/uifloatrange){:target="_blank"} representing the position range of the start pattern relative to the barcode's location.

```objc
@property(nonatomic, assign, readonly) UIFloatRange startPatternRange;
```
2. 
```swift
var startPatternRange: UIFloatRange { get }
```

### middlePatternRange

A [UIFloatRange](https://developer.apple.com/documentation/uikit/uifloatrange){:target="_blank"} representing the position range of the middle pattern relative to the barcode's location.

```swift
var middlePatternRange: UIFloatRange { get }
```

### endPatternRange

A [UIFloatRange](https://developer.apple.com/documentation/uikit/uifloatrange){:target="_blank"} representing the position range of the end pattern relative to the barcode's location.

<div class="sample-code-prefix"></div>
>- Objective-C

>1. 
```objc
@property(nonatomic, assign, readonly) UIFloatRange endPatternRange;
