Usage

HTMLString allows you to add and remove HTML entities from a String.

🔏 Add HTML Entities (Escape)

When a character is not supported into the specified encoding, the library replaces it with a decimal entitiy, such as & <=> & (compatible with HTML 4+).

You can choose between ASCII and Unicode escaping.

💡 Pro Tip: When your content supports UTF-8 or UTF-16, use Unicode escaping as it is faster and yields a less bloated output.

• addingASCIIEntities

Example

import HTMLString

let emoji = "My favorite emoji is 🙃"
let escapedEmoji = emoji.addingASCIIEntities // "My favorite emoji is 🙃"
let noNeedToEscapeThatEmoji = emoji.addingUnicodeEntities // "My favorite emoji is 🙃"

let snack = "Fish & Chips"
let escapedSnack = snack.addingUnicodeEntities // "Fish & Chips"

📝 Remove HTML Entities (Unescape)

To remove HTML entities from a String, use the removingHTMLEntities property.

Docs

• removingHTMLEntities

Example

import HTMLString

let escapedEmoji = "My favorite emoji is 🙃"
let emoji = escapedEmoji.removingHTMLEntities // "My favorite emoji is 🙃"

let escapedSnack = "Fish & Chips"
let snack = escapedSnack.removingHTMLEntities // "Fish & Chips"

Objective-C API

With Obj-C Mix and Match, you can import and use the HTMLString module from in Objective-C code.

The library introduces a set of Objective-C specific APIs as categories on the NSString type:

• [aString stringByAddingUnicodeEntities]; : Replaces every character incompatible with HTML Unicode encoding by a decimal HTML entitiy.
• [aString stringByAddingASCIIEntities]; : Replaces every character incompatible with HTML ASCII encoding by a decimal HTML entitiy.
• [aString stringByRemovingHTMLEntities]; : Replaces every HTML entity with the matching Unicode character.

Escaping Examples

@import HTMLString;

NSString *emoji = @"My favorite emoji is 🙃";
NSString *escapedEmoji = [emoji stringByAddingASCIIEntities]; // "My favorite emoji is 🙃"

NSString *snack = @"Fish & Chips";
NSString *escapedSnack = [snack stringByAddingUnicodeEntities]; // "Fish & Chips"

Unescaping Examples

@import HTMLString;

NSString *escapedEmoji = @"My favorite emoji is 🙃";
NSString *emoji = [escapedEmoji stringByRemovingHTMLEntities]; // "My favorite emoji is 🙃"

NSString *escapedSnack = @"Fish & Chips";
NSString *snack = [escapedSnack stringByRemovingHTMLEntities]; // "Fish & Chips"
