Question

I want to make a common function which takes a control as an argument (like UITextField, UIButton etc.)

Its working fine if I do like this

- (void)  myFunction : (UITextField*) : control
{

}

//But I want to make it common for any control

- (void)  myFunction : (`I don't know what to write here`) : control
{
     //suppose if control is UITextField, I can set its font and its size.
     //something like this
    [control setFont:[UIFont fontWithName:@"Verdana" size:12]];
}

Is this possible?

Answer 1

You can also go like this

- (void)  myFunction : (id) control
{
  if([control isKindOfClass:[UITextField class]]){
     // Your textfield condition
  }
}
