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;
}
