Easy UIFont Traits Querying (isBold/ isItalic) Found this hidden gem and made it a gist: http://joshua.nozzi.name/2012/08/easy-uifont-bold-and-italic-querying-with/ - and copyng of fonts to add specific traits

UIFont+Traits.h

#import <UIKit/UIKit.h>
#import <CoreText/CTFont.h>

@interface UIFont (Traits)

@property(nonatomic, readonly) CTFontRef CTFontRef;

@property(nonatomic, readonly) CTFontSymbolicTraits traits;
@property(nonatomic, readonly, getter=isBold) BOOL bold;
@property(nonatomic, readonly, getter=isItalic) BOOL italic;

-(UIFont*)fontWithSymbolicTraitsValues:(CTFontSymbolicTraits)values
                    symbolicTraitsMask:(CTFontSymbolicTraits)mask;

-(UIFont*)fontWithSize:(CGFloat)pointSize
  symbolicTraitsValues:(CTFontSymbolicTraits)Values
    symbolicTraitsMask:(CTFontSymbolicTraits)mask;

@end

UIFont+Traits.mm

#import "UIFont+Traits.h"

@implementation UIFont (Traits)

- (CTFontRef)CTFontRef {
#if !__has_feature(objc_arc)
    return (CTFontRef)self;
#else
    return (__bridge CTFontRef)self;
#endif
}

#pragma mark -

- (CTFontSymbolicTraits)traits
{
    CTFontSymbolicTraits symbolicTraits = CTFontGetSymbolicTraits(self.CTFontRef);
    return symbolicTraits;
}

- (BOOL)isBold
{
    CTFontSymbolicTraits symbolicTraits = [self traits];
    return (symbolicTraits & kCTFontBoldTrait);
}

- (BOOL)isItalic
{
    CTFontSymbolicTraits symbolicTraits = [self traits];
    return (symbolicTraits & kCTFontItalicTrait);
}

#pragma mark - 

-(UIFont*)fontWithSymbolicTraitsValues:(CTFontSymbolicTraits)Values symbolicTraitsMask:(CTFontSymbolicTraits)mask {
    return [self fontWithSize:self.pointSize symbolicTraitsValues:Values symbolicTraitsMask:mask];
}

-(UIFont*)fontWithSize:(CGFloat)pointSize symbolicTraitsValues:(CTFontSymbolicTraits)Values symbolicTraitsMask:(CTFontSymbolicTraits)mask {
    UIFont *newFont = (UIFont*)CTFontCreateCopyWithSymbolicTraits(self.CTFontRef, pointSize, NULL, Values, mask);
#if !__has_feature(objc_arc)
    return [newFont autorelease];
#else
    return newFont;
#endif
}
@end

added a method to copy a font with specific traits
