UIButton with pan gesture and press method - ios

Question

I would like to give a UIButton different features depending on if it is pressed and released once, or held down (ideally for 1.5 sec) and moved around the screen. I am using this code at the moment:
[button addTarget:self action:#selector(open:)
forControlEvents:UIControlEventTouchDown]
panRecognizer = [[UIPanGestureRecognizer alloc] initWithTarget:self action:#selector(move:)];
[panRecognizer setMinimumNumberOfTouches:1];
[panRecognizer setMaximumNumberOfTouches:1];
[panRecognizer setDelegate:self];
[button addGestureRecognizer:panRecognizer];
-(IBAction)open:(id)sender {}
-(void)move:(id)sender{}
move: works fine, but open: doesn't.

Answer 1

maybe you can use button's drag event, like
[button addTarget:self action:#selector(wasDragged:withEvent:)
forControlEvents:UIControlEventTouchDragInside];
You can look at this link: http://www.cocoanetics.com/2010/11/draggable-buttons-labels/
you can put a flag in move mehod, when enter touch up method, you check if the button has moved, to decide to trigger open related logic
#define BUTTON_DRAGGED_TAG -100
#define BUTTON_DEFAULT_TAG 0
- (void)onButtonTouchUpInside:(UIButton *)button withEvent:(UIEvent *)event
{
if (button.tag != BUTTON_DRAGGED_TAG)
{
//doOpen
}
button.tag = BUTTON_DEFAULT_TAG;
}
- (void)onButtonTouchUpOutside:(UIButton *)button withEvent:(UIEvent *)event
{
button.tag = BUTTON_DEFAULT_TAG;
}
- (void)onButtonTouchCancel:(UIButton *)button withEvent:(UIEvent *)event
{
button.tag = BUTTON_DEFAULT_TAG;
}
- (void)onButtonDraged:(UIButton *)button withEvent:(UIEvent *)event
{
button.tag = BUTTON_DRAGGED_TAG;
}

I did this, let me know if it works for you:
- (void)viewDidLoad
{
[super viewDidLoad];
UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(didRecognizeTapGesture:)];
tapGesture.cancelsTouchesInView = NO;
tapGesture.delegate = self;
[tapGesture requireGestureRecognizerToFail:self.scrollView.panGestureRecognizer];
[self.scrollView addGestureRecognizer:tapGesture];
self.tapGesture = tapGesture;
}
-(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch
{
if (touch.view == self.button)
{
return NO;
}
return YES;
}
- (void)didRecognizeTapGesture:(UITapGestureRecognizer*)gesture
{
if (gesture.state == UIGestureRecognizerStateEnded)
{
NSLog(#"GESTURE ENDED");
}
}
- (void)didPressButton:(UIButton*)sender
{
NSLog(#"BUTTON TOUCH UP INSIDE");
}
