This is OHAttributedStringAdditions," 56 | " a cool category that lets you manipulate NSAttributedString" 57 | " with nicer methods(1).

" 58 | "

For example you can change the font, make text" 59 | " bold, italics or underlined, …

" 60 | "

Amazing, isn't it?

" 61 | "

You can even indent the first line of your" 62 | " paragraphs to make nice text layouts, justify paragraphs, and a lot more!

Simply add the following line to your `Podfile`: 36 | 37 | ``` 38 | pod 'OHAttributedStringAdditions' 39 | ``` 40 | 41 | Then do a `pod install`. 42 | 43 | ## Example 44 | 45 | A demo project is provided in the repository. Don't hesitate to open `Example/AttributedStringDemo.xcworkspace` and play with it. 46 | 47 | If you have CocoaPods, you can even try that Sample project even if you don't have cloned the project yet, by using `pod try OHAttributedStringAdditions` in your terminal. 48 | 49 | ![Demo Capture](README.png) 50 | 51 | ## Future improvements 52 | 53 | * Improving **documentation on edge cases**, like documenting the behavior about when some attribute is not present or if we are allowed to pass nil to arguments. 54 | * Adding **support for OSX**. This should only need little adjustments, like getting rid of the `#import ` in the pch file, or replacing `UIColor` and `UIFont` classes with `NSColor` and `NSFont` (using macros to switch from one to another depending on the SDK), but that still requires some work and tests. 55 | 56 | > _Note: The original code of these categories comes from my old `OHAttributedLabel` pod, which is now deprecated as I don't have time to maintain it. As this previous implementation was based on CoreText and was not compatible (sometimes even crash) with UIKit/TextKit, I converted those categories to create this UIKit-compliant `NSAttributedString`, not related to CoreText and `OHAttributedLabel` anymore and that now work with latest versions of iOS/UIKit/TextKit._ 57 | 58 | ## Licence 59 | 60 | This component is under the MIT Licence (See the `LICENSE` file). 61 | -------------------------------------------------------------------------------- /README.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/AliSoftware/OHAttributedStringAdditions/15d5d01c917ab60ac0be3ece523229a3de44a866/README.png -------------------------------------------------------------------------------- /Source/NSAttributedString+OHAdditions.h: -------------------------------------------------------------------------------- 1 | /******************************************************************************* 2 | * 3 | * Copyright (c) 2010 Olivier Halligon 4 | * 5 | * Permission is hereby granted, free of charge, to any person obtaining a copy 6 | * of this software and associated documentation files (the "Software"), to deal 7 | * in the Software without restriction, including without limitation the rights 8 | * to use, copy, modify, merge, publish, distribute, sublicense, and/or sell 9 | * copies of the Software, and to permit persons to whom the Software is 10 | * furnished to do so, subject to the following conditions: 11 | * 12 | * The above copyright notice and this permission notice shall be included in 13 | * all copies or substantial portions of the Software. 14 | * 15 | * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR 16 | * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, 17 | * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
