You can assign a BOOL value to your button and check this value everytime the button is tapped:

@implementation youCustomViewController {
    BOOL buttonSelectionned;
    UIButton *myButton;
}

- (void)viewDidLoad
{
    /* Init objects */
    buttonSelectionned = NO;

    [super viewDidLoad];
    // Do any additional setup after loading the view.

    myButton = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 100, 100);
    myButton setImage:[UIImage imageNamed:@"MinSelected.png"] forState:UIControlStateNormal];
    [myButton addTarget:self action:@selector(buttonTapped:) forControlEvents:UIControlEventTouchUpInside];
}

and then implement your method buttonTapped

- (void)buttonTapped:(id)sender
{
    if (buttonSelectionned) {
        buttonSelectionned = NO;
        myButton setImage:[UIImage imageNamed:@"MinSelected.png"] forState:UIControlStateNormal];
    } else {
        buttonSelectionned = YES;
        myButton setImage:[UIImage imageNamed:@"MinSelected2.png"] forState:UIControlStateNormal];
    }  
}
