Question

Is it a true statement that UIGesturesRecognizer effectively replaced any manual control afforded to us by

- touchesBegan:withEvent:
– touchesMoved:withEvent:
– touchesEnded:withEvent:
– touchesCancelled:withEvent:

Just looking for a confirmation here.

Thanks

Answer 1

If you are saying that the methods is not going to be called, this is not true.

If you are saying that the UIGesture can do what this methods do, the answer is yes, with UIGestures you can do all that you can do with this methods you posted. And probably in an easy way to code 🙂

You can get the state of the gesture, the view and others.
And with the UIGestures is easy to know if is a tap, a longpress, a swipe, etc.

Take a look at the Reference

Edit:

An example for you, to add a PanGesture, that will be handled after:

UIPanGestureRecognizer* pan = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(panGestureHandler:)];
[self.view addGestureRecognizer:pan];

your method that will handle the pan, will receive the gesture, and will look like:

-(void)panGestureHandler:(UIPanGestureRecognizer *)gesture{
    CGPoint postionInView = [gesture translationInView:self.view];
    [yourView setCenter:postionInView];
}
