廢話不多說，直接上代碼

NSData *data = [NSData dataWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"方正蘭亭纖黑簡體" ofType:@"TTF"]];
CGDataProviderRef dataRef = CGDataProviderCreateWithCFData((__bridge CFDataRef)data);
CGFontRef fontRef = CGFontCreateWithDataProvider(dataRef);
CFStringRef fontName = CGFontCopyFullName(fontRef);
NSLog(@"%@",(__bridge NSString *)fontName);
CFRelease(dataRef);
CFRelease(fontRef);
CFRelease(fontName);
