Installation

  • pod 'IconFontKit/Core' to install only the IFIcon abstract class.
  • pod 'IconFontKit' to install all icon packs.
  • pod 'IconFontKit/{Font Identifier}' to install certain of icon packs, e.g. pod 'IconFontKit/FontAwesome'.

Usage

  • An icon can be created by three ways: code like @"\uf179", type like IFFAApple, identifier like @"fa-apple".
    The code and type way are recommended.

      IFFontAwesome *faIcon = [IFFontAwesome iconWithCode:@"\uf17b" fontSize:20.0];
      IFIonicons *ionIcon = [IFFontAwesome iconWithType:IFIIWifi fontSize:20.0];
      IFOcticons *octIcon = [IFOcticons iconWithIdentifier:@"octicon-gift" fontSize:20.0];
  • IFIcon are backend with NSAttributedString, and there are several methods for accessing attributes, like:

    - (NSDictionary *)attributes;
    - (void)addAttribute:(NSString *)name value:(id)value;
    - (void)removeAttribute:(NSString *)name;
    - (void)setAttributes:(NSDictionary *)attributes;
  • You may create an icon image using -[IFxxxIcon imageWithSize:] or +[IFxxxIcon imageWithType:color:...] etc.

    UIImage *image = [IFFontAwesome imageWithType:IFOIArrowRight color:nil imageSize:CGSizeMake(30, 30)];
  • Use +[IFxxxIcon fontWithSize:] to get an icon font instance of UIFont type.

  • [UIImage if_imageWithStackedIcons:imageSize:] can stack multi-icons to one image.

    /**
     * Draws the IFIcons on an image.
     * These icons will be centered horizontally and vertically by default.
     * You can set the `drawingPositionAdjustment` property to adjust drawing offset for each icon.
     *
     * @param icons The icons to be drawn. The first icon will be drawn on the bottom and the last icon will be drawn on the top.
     * @param imageSize Height and width for the generated image.
     *
     * @return An image with the icons.
     */
    + (UIImage *)if_imageWithStackedIcons:(NSArray <IFIcon *>*)icons imageSize:(CGSize)imageSize;

    For example:

    IFFontAwesome *container = [IFFontAwesome iconWithType:IFFASquareO fontSize:100.0 color:[UIColor colorWithWhite:0.88 alpha:1.0]];
    container.drawingPositionAdjustment = UIOffsetMake(0, 4);
    IFFontAwesome *forbidden = [IFFontAwesome iconWithType:IFFABan fontSize:70.0 color:[[UIColor redColor] colorWithAlphaComponent:0.6]];
    IFFontAwesome *usbIcon = [IFFontAwesome iconWithType:IFFAUsb fontSize:50];
    
    UIImage *stackedImage = [UIImage if_imageWithStackedIcons:@[container, usbIcon, forbidden] imageSize:CGSizeMake(100, 100)];

Using Custom Icon Fonts

  • To use your own icon fonts, just subclass IFIcon and implement + (NSURL *)fontFileURL method.
  • If the font name is not the same as the filename of fontFileURL, you need to implement + (NSString *)fontName method as well.
  • If you want to use identifier way to create icons, you need to implement + (NSDictionary *)allIcons method as well.
  • Icon types of your custom fonts are the icon's unicode hexadecimal value. e.g. icon code \uf100's type is 0xf100.
  • FYI: You can generate icon fonts using IcoMoon app, Fontello, Fontastic or other awesome services.
  • See "IconFontKitExample/MyFontIcons" for demo.

    // MyFontIcons.h
    
    #import <IconFontKit/IFIcon.h>
    
    typedef NS_ENUM(IFIconType, MyFontIconsType) {
        MFFacebookSquared   = 0xa100,
        MFChat              = 0xa101,
        MFEmoHappy          = 0xa102,
        MFThumbsUp          = 0xa103,
        MFThumbsUpAlt       = 0xa104,
        MFLinkExt           = 0xa105,
        MFVolumeUp          = 0xa106,
        MFCogAlt            = 0xa107,
        MFCode              = 0xa108,
    };
    
    @interface MyFontIcons : IFIcon
    @end
    // MyFontIcons.m
    
    #import "MyFontIcons.h"
    
    @implementation MyFontIcons
    
    + (NSURL *)fontFileURL {
        return [[[NSBundle mainBundle] resourceURL] URLByAppendingPathComponent:@"myfonticons.ttf"];
    }
    
    // Optional becase the font name is the same as the filename of font.
    //+ (NSString *)fontName {
    //    return @"myfonticons";
    //}
    
    + (NSDictionary *)allIcons {
        return @{
                 @"facebook-squared":  @"\ua100",
                 @"chat":              @"\ua101",
                 @"emo-happy":         @"\ua102",
                 @"thumbs-up":         @"\ua103",
                 @"thumbs-up-alt":     @"\ua104",
                 @"link-ext":          @"\ua105",
                 @"volume-up":         @"\ua106",
                 @"cog-alt":           @"\ua107",
                 @"code":              @"\ua108",
                 };
    }
    @end
