Question

I am new to iPhone programming and when I use this code to enable/disable a button nothing happens. I connected my button through an IBOutlet and I know when I disable it in viewDidLoad it works. I just cant figure out why this method isn’t working.

- (void) multiplicationButtonPressed {
    if (multiplicationIsPressed) {
        multiplicationButton.enabled = NO; 
    } else {
        multiplicationButton.enabled = YES; 
    }
}

Answer 1

Please Check that your IBOutlet had connected properly for this button or not and then

use this piece of code

- (IBAction) multiplicationButtonPressed 
 {
    multiplicationButton.selected = !multiplicationButton.selected;
 }

That’s it. You don’t need to have any boolean flag. It works like toggle.
