KXHtmlLabel

KXHtmlLabel is a powerful UILabel/UIButton extension. It enables UILabel/UIButton to interprete HTML tags. Besides, it also enables UILabel/UIButton to display awesome icons from FontAwesome.

Features

• Enables UILabel and UIButton to interprete HTML tags
• Supports UILabel and UIButton and their subclasses.
• Supports FontAwesome html tags
• Supports paragraphs with text alignment, wordwrap and line spacing
• Supports font weight attribute on iOS 8.2 and above

Requirements

Requires iOS 8.0+ and ARC.

Installation

CocoaPods

The easiest way of installing KXHtmlLabel is via CocoaPods.

pod 'KXHtmlLabel'

Old-fashioned way

• Add all subfolders and *.h, *.m, FontAwesome.otf from folder KXHtmlLabel/ to your project.
• Add CoreText.framework to your linked frameworks.
• #import "KXHtmlLabel.h" where you want to use the framework.

Usage

Include the header

#import "KXHtmlLabel.h"

Hello World example

Use -(void) setHtml:(NSString *) method to display HTML strings on UILabel

Use -(void) setHtmlTitle:(NSString *) forState:(UIControlState) for UIButton

// Display HTML on UILabel
[label1 setHtml:@"<p align=\"right\">Hello <b>World</b>! This is <u>awesome</u>!</p>"];
// Display HTML on UIButton
[button1 setHtmlTitle:@"<b>Hello</b> <font color=\"#00ff00\">World</font>" forState:UIControlStateNormal];

Additional settings

KXHtmlLabel uses its own XML parser to parse HTML strings. To avoid parsing identical strings repeatedly (for instance, display HTML strings in a UITableViewCell), KXHtmlLabel caches the parsed results of HTML strings. This feature is turned on by default.

You can turn off this feature using the following code.

[KXXmlCacheManager sharedManager].enabled = NO; 

Also, you can clear the cache by using the following code.

[[KXXmlCacheManager sharedManager] clear];
