UIButton UIControl target action 2 actions for single button

Question

I have a button that has a selected and non-selected state.

My target action code for the button is this:

NSArray *targets = [myButton actionsForTarget:self forControlEvent:UIControlEventTouchUpInside];

    if ([targets count] == 0) {
        [myButton addTarget:self action:@selector(save:) forControlEvents:UIControlEventTouchUpInside];

When the button is pressed, it goes to selected state in the method.

If the button is selected, a different action should be called. Is there any unintended consequence to doing it this way or is there a way to add actions with UIControlState instead?

if (myButton.selected == NO){
[myButton addTarget:self action:@selector(save:) forControlEvents:UIControlEventTouchUpInside];
}
else{
[myButton addTarget:self action:@selector(delete:) forControlEvent:UIControlEventTouchUpInside];
}

-(IBAction)myButton:(id)sender
{
UIButton *btn = (UIButton*)sender;
btn.selected = !btn.selected;
if(btn.selected)
{
    //Do whatever you want when button is selected
    [self delete];
}
 else
{
    //Do whatever you want when button isDeselected
     [self save];
}
}
