Use UIControlEventTouchDragInside and UIControlEventTouchUpInside events of UIButton like

// add drag listener
[button addTarget:self action:@selector(wasDragged:withEvent:) forControlEvents:UIControlEventTouchDragInside];
// add tap listener
[button addTarget:self action:@selector(wasTapped:) forControlEvents:UIControlEventTouchUpInside];

You can use hbdraggablebutton control..

- (void)viewDidLoad {
  [super viewDidLoad];
  [eventButton addTarget:self action:@selector(dragOut:withEvent:)forControlEvents:UIControlEventTouchDragOutside |UIControlEventTouchDragInside];
   }

-(IBAction)dragOut: (id)sender withEvent: (UIEvent *) event {
 UIButton *selected = (UIButton *)sender;
 selected.center = [[[event allTouches] anyObject] locationInView:self.view];
 }
