getLocalizedTextLines

Get all the text lines in an array of DSLocalizedTextLineElement, which is the basic unit of the localized text line result.

Objective-C
Swift

-(nullable NSArray<DSLocalizedTextLineElement*>*)getLocalizedTextLines;

func getLocalizedTextLines() -> [DSLocalizedTextLineElement]?

Return value

All the text lines in an array of DSLocalizedTextLineElement, which is the basic unit of the localized text line result.

getCount

Get the number of text lines in this unit.

Objective-C
Swift

```
-(NSInteger)getCount;

Objective-C
Swift

-(nullable DSLocalizedTextLineElement*)getLocalizedTextLine:(NSInteger)index;

func getLocalizedTextLine(_ index: Int) -> DSLocalizedTextLineElement?

Parameters

index: The index of the localized text line to be retrieved.

Return value

The localized text line at the specified index in a LocalizedTextLineElement object.

removeAllLocalizedTextLines

Remove all the localized text lines from the unit.

Objective-C
Swift

```
-(void)removeAllLocalizedTextLines;
```
```
func removeAllLocalizedTextLines()
```

removeLocalizedTextLine

Remove a localized text line from the unit.

Objective-C
Swift

-(NSInteger)removeLocalizedTextLine:(NSInteger)index;

func removeLocalizedTextLine(_ index: Int) -> Int

Parameters

index: The index of the localized text line to be removed.

Return value
