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",

             @"cog-alt":           @"\ua107",
             @"code":              @"\ua108",
             };
