Getting a return value from a button's action method

Question

I have a button, and I've set an action in code:

[buttonOk addTarget:self action:@selector(check:) forControlEvents:UIControlEventTouchUpInside];

The check: method returns an int. How can I receive this int?

Answer 1

Create a different method that calls check:. Have this method process the return value.

- (void)mymethod:(id)sender {
  int value = [self check:sender];
  // use your value or send it somewhere
}
