MTStringAttributes
An easier way to create an attributes dictionary for NSAttributedString (for iOS and OSX)
Installation
In your Podfile, add this line:
pod "MTStringAttributes"
pod? => https://github.com/CocoaPods/CocoaPods/
Example Usage
#include <MTStringAttributes.h>
Create an attributes object
MTStringAttributes *attributes = [[MTStringAttributes alloc] init];
Set some basic properties
attributes.font = nil;
attributes.textColor = [UIColor redColor]; //or NSColor in OSX
attributes.backgroundColor = [UIColor blackColor]; //or NSColor in OSX
attributes.strikethrough = YES;
attributes.underline = YES;
Some more advanced stuff
attributes.ligatures = YES;
attributes.kern = 1.0f;
attributes.outlineColor = [UIColor blueColor]; //or NSColor in OSX
attributes.outlineWidth = 2.0f;
Finally
NSAttributedString *str = [[NSAttributedString alloc] initWithString:@"The attributed string!"
attributes:[attributes dictionary]];
Parser
Relying on Slash, MTStringParser allows you to add styles to tags and then generate attributed strings from markup of those tags.
#include <MTStringParser.h>
[[MTStringParser sharedParser] addStyleWithTagName:@"red"
font:[UIFont systemFontOfSize:12]
color:[UIColor redColor]];
NSAttributedString *string = [[MTStringParser sharedParser]
attributedStringFromMarkup:@"This is a <red>red section</red>"];
###And like a beautiful symphony, they work together like so:
Easily create a string attributes object
MTStringAttributes *attributes = [[MTStringAttributes alloc] init];
attributes.font = [UIFont fontWithName:@"HelveticaNeue" size:14];
attributes.textColor = [UIColor blackColor];
Add this as the default for the whole string we're about to parse
[[MTStringParser sharedParser] setDefaultAttributes:attributes];
Define a style for a tag called <relative-time> that uses this font and has this color:
[[MTStringParser sharedParser] addStyleWithTagName:@"relative-time"
font:[UIFont fontWithName:@"HelveticaNeue-Bold" size:14]
color:[UIColor colorWithRed:215.0/255.0 green:0 blue:0 alpha:1]];
And easily add another tag that has a font, color, background color and is underlined:
[[MTStringParser sharedparser] addStyleWithTagName:@"em"
font:[UIFont systemFontOfSize:14]
color:[UIColor whiteColor]
backgroundColor:[UIColor blackColor]
strikethrough:NO
underline:YES];
Now write the markup using the tags you defined styles for:
NSString *markup = [NSString stringWithFormat:@"You can have a <em>complex<em> string that \
uses <em>tags</em> to define where you want <em>styles</em> to be defined. You needed \
this <relative-time>%@</relative-time>.", timeAgo];
And boom, your attributed string:
NSAttributedString *attributedString = [[MTStringParser sharedParser] attributedStringFromMarkup:markup];
