You can extends UIButton and add a custom property

//UIButtonDictionary.h
#import 

@interface UIButtonDictionary : UIButton

@property(nonatomic, strong) NSMutableDictionary* attributes;

@end

//UIButtonDictionary.m
#import "UIButtonDictionary.h"

@implementation UIButtonDictionary
@synthesize attributes;

@end
