Question

有没有人知道如何从Xcode的info.plist文件中的'应用程序提供的字体'键获取自定义字体列表？谢谢

以下代码从Info.plist中读取自定义字体文件列表,并从字体文件中提取完整的字体名称.(部分代码复制自/sf/answers/1226381831/ ,只需稍加修改和ARC调整).

Objective-C的

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等价物:

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)
            }
        }
    }
}
