Question

just wondering how to make a button “START” that when pressed triggers a function and the text changes to “STOP”. then when pressed again the function will stop and the text changes back to “START”

Ive got the button already that starts the function. and i can handle changing the title, just not sure on what to use to make the 1 button have 2 functions

Add the IBAction method like:

- (IBAction)buttonTapped:(id)sender
{
  UIButton *btn = (UIbutton *)sender;
  NSString *title=btn.titleLabel.text; 
  if ([title isEqualToString:@"Start"])
  {
   //Start 
  }else
  {
   //Stop
  }
}
