Question

我想查找我已复制到Documents Directory的.ttf文件的PostScript名称...这样我就可以在不更改.plist文件的情况下以编程方式将字体设置为标签。

我知道这段代码：

  for (NSString *fontFamilyName in [UIFont familyNames]) {
    for (NSString *fontName in [UIFont fontNamesForFamilyName:fontFamilyName]) {
        NSLog(@"Family: %@    Font: %@", fontFamilyName, fontName);
    }
}

但是我想找到一个文件示例的PostScript名称：segoe.ttf

显然会有不同的字体文件被复制到Documents Directory，我想只为每个文件获取PostScript名称，而不是像上面提到的代码那样。谢谢......

所以我使用这段代码得到它：

- (NSString *)realNameOfFont:(NSString *)fullFontName {

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);

NSString *documentsDirectory = [paths objectAtIndex:0];

NSString *docFilePath = [documentsDirectory stringByAppendingPathComponent:fullFontName];

NSData *data = [NSData dataWithContentsOfFile:docFilePath];
if (data == nil) {
    NSLog(@"Failed to load font. Data at path %@ is null", fullFontName);
    return nil;
}
  CFErrorRef errorRef;
    CGDataProviderRef provider = CGDataProviderCreateWithCFData((CFDataRef)data);
    CGFontRef font = CGFontCreateWithDataProvider(provider);
    NSString *realFontName = (__bridge NSString *)CGFontCopyPostScriptName(font);
    if (!CTFontManagerRegisterGraphicsFont(font, &errorRef)) {
        NSError *error = (__bridge NSError *)errorRef;
        if (error.code != kCTFontManagerErrorAlreadyRegistered) {
            NSLog(@"Failed to load font: %@", error);
       }
    }
    NSLog(@"PostScript Font Name:%@", realFontName);
    CFRelease(font);
    CFRelease(provider);
    return realFontName;

PostScript使用Objective-C而不是所有已安装字体的字体文件名称（.ttf）
