UIButton - Checkmark not showing

I'm trying to create a uibutton to work as a checkbox. Everything is working fine but the view: I'm setting to change the view when clicked. When it is supposed to show no checkmark it's fine, but when I need to show the checkmark, it's not working. This is what happens:

image with no checkmark image with checkmark

And this is the code:

- (void)viewDidLoad {
    [super viewDidLoad];

    [self.myButton setTitle:@"\u2610" forState:UIControlStateNormal];
    [self.myButton setTitle:@"\u2610" forState:UIControlStateHighlighted];
    [self.myButton setTitle:@"\u2610" forState:UIControlStateDisabled];
    [self.myButton setTitle:@"\u2610" forState:UIControlStateNormal];
    [self.myButton setTitle:@"\u2611" forState:UIControlStateSelected];
}

//action sent to the button when touched up inside
- (IBAction)moneyButtonClicked:(id)sender {
    UIButton *button  = (UIButton *)sender;
    button.selected = !button.selected;
}

What is wrong?

Regards!

I think you forgot to add action event from your storyboard or by code

- (void)viewDidLoad {
    [super viewDidLoad];
    [self addMenuButton];

    [self.myButton setTitle:@"\u2610" forState:UIControlStateNormal];
    [self.myButton setTitle:@"\u2611" forState:UIControlStateSelected];

    [self.myButton addTarget:self action:@selector(moneyButtonClicked:) forControlEvents:UIControlEventTouchUpInside];
}

- (IBAction)moneyButtonClicked:(UIButton *)sender {

    NSLog(@"%d",sender.selected);

    sender.selected = !sender.selected;
}

Button type must be Custom else you will found the tint color of button with the selection.

Answers from ooops and Ashish Kakkad, but the problem with my code was: in the interface builder, my button was set as a System button and not as a Custom.

I just create a new project and add the following code. It works like the gif shows. You can do a compare.

enter image description here

- (void)viewDidLoad {
    [super viewDidLoad];
    self.checkButton = [UIButton buttonWithType:UIButtonTypeCustom];
    [self.checkButton addTarget:self action:@selector(moneyButtonClicked:) forControlEvents:UIControlEventTouchUpInside];
    self.checkButton.frame = CGRectMake(50, 50, 50, 50);
    self.checkButton.titleLabel.textColor = [UIColor redColor];
    self.checkButton.backgroundColor = [UIColor yellowColor];
    [self.checkButton setTitle:@"\u2610" forState:UIControlStateNormal];
    [self.checkButton setTitle:@"\u2611" forState:UIControlStateSelected];
    [self.view addSubview:self.checkButton];
}

- (IBAction)moneyButtonClicked:(id)sender {
    UIButton *button  = (UIButton *)sender;
    button.selected = !button.selected;
}
