List of Fonts Provided by Application (iOS)

问题

does anyone know how to get a list of custom fonts from the 'Fonts provided by application' key in the info.plist file in Xcode? Thanks

回答1:

The following code reads the list of custom font files from the Info.plist, and extracts the full font name from the font file. (Parts of the code is copied from https://stackoverflow.com/a/17519740/1187415 with small modifications and ARC adjustments).

Objective-C

NSDictionary* infoDict = [[NSBundle mainBundle] infoDictionary];
NSArray* fontFiles = [infoDict objectForKey:@"UIAppFonts"];

for (NSString *fontFile in fontFiles) {
    NSLog(@"file name: %@", fontFile);
    NSURL *url = [[NSBundle mainBundle] URLForResource:fontFile withExtension:NULL];
    NSData *fontData = [NSData dataWithContentsOfURL:url];
    CGDataProviderRef fontDataProvider = CGDataProviderCreateWithCFData((__bridge CFDataRef)fontData);
    CGFontRef loadedFont = CGFontCreateWithDataProvider(fontDataProvider);
    NSString *fullName = CFBridgingRelease(CGFontCopyFullName(loadedFont));
    CGFontRelease(loadedFont);
    CGDataProviderRelease(fontDataProvider);
    NSLog(@"font name: %@", fullName);
}

Swift 3 equivalent:

if let infoDict = Bundle.main.infoDictionary,
    let fontFiles = infoDict["UIAppFonts"] as? [String] {
    for fontFile in fontFiles {
        print("file name", fontFile)
        if let url = Bundle.main.url(forResource: fontFile, withExtension: nil),
            let fontData = NSData(contentsOf: url), 
            let fontDataProvider = CGDataProvider(data: fontData) {
            let loadedFont = CGFont(fontDataProvider)
            if let fullName = loadedFont.fullName {
                print("font name", fullName)
            }
        }
    }
}
