Answer 1

// set titles in viewDidLoad Method or in interface builder
[button setTitle:@"Start" forState:UIControlStateNormal];
[button setTitle:@"Cancel" forState:UIControlStateSelected];


- (IBAction)startBtn:(id)sender {
    UIButton *button = sender;
    button.selected = !button.selected;

    if (button.slected) {
       // start process
    }
    else {
      // stop process
   }

}
