Have a button stop working when my labels text = 0?

[xcoderx]

Hey guys i have a label and you can + or - 1 from the label so its like a counter. And when it hits 0 from subtracting so many times, I want the button to stop working. I got it to do this. But my problem is getting the button to start working again after the value is anything greater than 0. Here is my code:

 - (IBAction)subtractButton:(id)sender {
    int val = [label.text intValue];

    [label setText:[NSString stringWithFormat:@"%d",[label.text intValue] -1]];  
    
    if(val - 1 <= 0) { 
        UIButton *button = (UIButton *)sender;
        [button setEnabled:NO]; 
    }
}

Thanks in advance for all the help everybody!

Judging by what you have here, I will assume that you have an "add" method. Whenever you add something using that button, you will be always greater than, or equal to zero if you subtract - hence you can just enable the subtractionButton whenever you add something.

 - (IBAction)addButton:(id)sender {
    
    // ...

    if (![button enabled]) [button setEnabled:YES]; 

}
