About these classes
This class allows you to use a
NSAttributedStrings, in order to display styled text with mixed style (mixed fonts, color, size, ...) in a unique label. It is a subclass of
UILabel, which adds an
attributedText property. Use this property, instead of the
text property, to set and get the
NSAttributedString to display.
This class also support hyperlinks and URLs. It can automatically detect links in your text, color them and make them touchable; you can also add "custom links" in your text by attaching an URL to a range of your text and thus make it touchable, and even then catch the event of a touch on a link to act as you wish to.
NSAttributedString and NSTextChecking additions
In addition to this
OHAttributedLabel class, you will also find a category of NS(Mutable)AttributedString to ease creation and manipulation of common attributes of NSAttributedString (to easily change the font, style, color, ... of a range of the string). See the header file
NSAttributedString+Attributes.h for a list of those comodity methods.
There is also a category for
NSTextCheckingResult that adds the
extendedURL property. This property returns the same value as the
URL value for standard link cases, and return a formatted Maps URL for
NSTextCheckingTypeAddress link types that will open Google Maps in iOS version before 6.0, and the Apple's Maps application in iOS 6.0 and later.
How to use in your project
To use this classes in your project:
- include the "OHAttributedLabel" and "NSAttributedString+Attributes" header (.h) and source (.m) files in your Xcode project
- Don't forget to import the CoreText framework in your project (otherwise you will have linker errors when you will compile)
This project is compatible with ARC since its version of August 16th, 2012.
Sample code & Other documentation
There is no explicit documentation of the class yet sorry (never had time to write one), but
- The method names should be self-explanatory (hopefully) as I respect the standard ObjC naming conventions.
- There are doxygen/javadoc-like documentation in the headers that should also help you describe the methods
Also see the "AttributedLabel Example" sample project which tries to demonstrate quite every standard usage of this class — including text alignment, dynamically changing the style of a range of text, adding custom links, catching the touch on links to change the default behavior, and customizing the appearance/color of links.
