CGRect frame = CGRectMake(0, 0, image.size.width, image.size.height);
UIButton* button = [[UIButton alloc] initWithFrame:frame];
[button setTitle:@"Display" forState:UIControlStateNormal & UIControlStateHighlighted];
[button setImage:image forState:UIControlStateNormal];
[button setImage:[UIImage imageNamed:selectedImage] forState:UIControlStateSelected];
[button addTarget:self action:@selector(button_Clicked:) forControlEvents:UIControlEventTouchUpInside];
