应用程序提供的字体列表（iOS） [英] List of Fonts Provided by Application (iOS)

问题描述

没有人知道如何从Xcode中的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

解决方案

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 https://stackoverflow.com/a/17519740/1187415 $

Objective-C

  NSDictionary * infoDict = [[NSBundle mainBundle] infoDictionary]; 
 NSArray * fontFiles = [infoDict objectForKey：@UIAppFonts]; 
 $ b $（字体文件中的NSString * fontFile）{
 NSLog（@文件名：％@，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）; 
 
 $ / code> 

Swift 3相当于：



 如果让infoDict = Bundle.main.infoDictionary，
让fontFiles = infoDict [UIAppFonts]为？ fontFiles中fontFile的$ {
 {
 print（file name，fontFile）
 if url = Bundle.main.url（forResource：fontFile，withExtension：nil），
让fontData = NSData（contentsOf：url），
 let fontDataProvider = CGDataProvider（data：fontData）{
 let loadedFont = CGFont（fontDataProvider）
 if fullName = loadedFont.fullName { 
 print（font name，fullName）
} 
} 
} 
} 
  




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

解决方案

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)
            }
        }
    }
}
