本文介绍了如何在iOS应用中使用自定义字体文件，包括单个字体文件和字体组合（TTC），适用于iOS 7.0及以上版本。通过Objective-C代码示例展示了如何注册并创建自定义字体。

-(UIFont*)customFontWithPath:(NSString*)path size:(CGFloat)size
{
    NSURL *fontUrl = [NSURL fileURLWithPath:path];
    CGDataProviderRef fontDataProvider = CGDataProviderCreateWithURL((__bridge CFURLRef)fontUrl);
    CGFontRef fontRef = CGFontCreateWithDataProvider(fontDataProvider);
    CGDataProviderRelease(fontDataProvider);
    CTFontManagerRegisterGraphicsFont(fontRef, NULL);
    NSString *fontName = CFBridgingRelease(CGFontCopyPostScriptName(fontRef));
    UIFont *font = [UIFont fontWithName:fontName size:size];
    CGFontRelease(fontRef);
    return font;
}

返回字体组合（TTC）适合ios7.0以上
-(NSArray*)customFontArrayWithPath:(NSString*)path size:(CGFloat)size
{
    CFStringRef fontPath = CFStringCreateWithCString(NULL, [path UTF8String], kCFStringEncodingUTF8);
    CFURLRef fontUrl = CFURLCreateWithFileSystemPath(NULL, fontPath, kCFURLPOSIXPathStyle, 0);
    CFArrayRef fontArray =CTFontManagerCreateFontDescriptorsFromURL(fontUrl);
    CTFontManagerRegisterFontsForURL(fontUrl, kCTFontManagerScopeNone, NULL);
    NSMutableArray *customFontArray = [NSMutableArray array];
    for (CFIndex i = 0 ; i < CFArrayGetCount(fontArray); i++){
        CTFontDescriptorRef  descriptor = CFArrayGetValueAtIndex(fontArray, i);
        CTFontRef fontRef = CTFontCreateWithFontDescriptor(descriptor, size, NULL);
        NSString *fontName = CFBridgingRelease(CTFontCopyName(fontRef, kCTFontPostScriptNameKey));
        UIFont *font = [UIFont fontWithName:fontName size:size];
        [customFontArray addObject:font];
    }
    
    return customFontArray;
}
