How can I add a swipe hint?

[oferRounds]

I'm using the the class in my on boarding. I'd like to add hint, with delicate card move to hint the user that the view is he's currently seeing is swipeable.

Anyone has an idea how can I achieve this? I'd like the change to appear "real", as if someone really did a little swipe to the right, and then removed his finger.

@zhxnlai - I tried to use UIView animateWithDuration, but was not able to achieve an effect which looked real.

Any idea maybe?

How about animating the anchorView?

[oferRounds]

Thanks! What does the anchorView represent?

[zhxnlai]

It is a special view used to animate the card with physics

Ok, so you what you have in mind is to use UIView's animateWithDuration and just set a new location to it? And what will be the best way to make it go back to it's origin (as if the user removed his finger)?

[zhxnlai]

After the user places his/her finger on the cardView, the library will start to animate the cardView based on anchorView's location. In this case, just animate the anchorView and the cardView will follow it.

Ok, got you. Two more questions please:

1. Does it also consider his transform state? I'd like to give a delicate twist.
2. And how will I mimic the finger removal - snapping back the view to its origin?

[zhxnlai]

1. Only the position of anchorView is used
2. Do you have access to ViewManager class? If so you can call setStateSnapping to mimic finger removal

[oferRounds]

1. Then what will be the best way to animate a delicate rotation?
2. Sounds good - I do have

[oferRounds]

Did a very preliminary test of changing the location of the top view via the anchorView, but it does not move... This is the code I use:

-(void)showHint
{
    ViewManager *viewManager = [self managerForView:self.topView];
    UIView *anchorView = viewManager.anchorView;

    anchorView.center = CGPointMake(anchorView.center.x + 15.0, anchorView.center.y + 15.0);
}

I tried also another approach: Passing an array of movement values (which I recorded earlier when testing a slight hint) to a method which I added, which is similar to the gesture handler method. This method handles these values (the first value is treated as the began, the last as the end and all the others - as changed), but it didn't really work - the top card did not move...

@zhxnlai - any chance you can have a look at my trials here?
