MyUIButton.h

#import <UIKit/UIKit.h>

@interface MyUIButton : UIButton

@property (nonatomic, assign) BOOL isPressed;
- (void)setIsPressed:(BOOL)isPressed;

@end

MyUIButton.m

#import "MyUIButton.h"

@implementation MyUIButton

- (instancetype)init
{
    self = [super init];
    if (self) {
        
    }
    return self;
}

- (void)setIsPressed:(BOOL)isPressed {
    _isPressed = isPressed;
    if (isPressed) {
        [self setBackgroundColor:[UIColor grayColor]];
    }
    else {
        [self setBackgroundColor:[UIColor whiteColor]];
    }
}

/*
// Only override drawRect: if you perform custom drawing.
// An empty implementation adversely affects performance during animation.
- (void)drawRect:(CGRect)rect
{
    // Drawing code
}
*/
