提供字體文件路徑，返回所需要字體：

-(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;
}

這樣就不需要在plist設(shè)定任何東西，只需要得到字體庫文件的路徑，就可以取出對應(yīng)的字體。

上面的方法對于TTF、OTF的字體都有效，但是對于TTC字體，只取出了一種字體。因為TTC字體是一個相似字體的集合體，一般是字體的組合。所以如果對字體要求比較高，所以可以用下面的方法把所有字體取出來：

-(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;
}
