When adding a dragged node from a supernode to another, it causes the panGesture to be cancelled.
private func dragged(_ panGesture: UIPanGestureRecognizer) {
guard panGesture.view != nil else {return} // View here is wrapped in ASDisplayNode
switch panGesture.state {
case .began:
self.superview!.superview!.addSuperview(panGesture.view!)
case .cancelled:
print("Cancelled!") // Fires, Why???
}
}
However, this exact example works perfectly with UIKit default UIViews.
Also, moving the layers to super does work(ish), and doesn't detach the layer from the node, but it's coordination is set to (0,0) (on the supernode.supernode)
The problem with this approach is that I cannot manipulate the layer directly, nor the node/uiview position change affect anything. (including all sorts of setNeedsLayout, setNeedsDisplay.
For some reason on the next .changed event, if I change the view position, it does affect it. (Code with notes):
func dragged(_ panGesture: UIPanGestureRecognizer) {
guard let draggedView = panGesture.view else { return }
switch panGesture.state {
case .began:
_beginDragLocation = draggedView.center
_beginDragLocation = draggedView.convert(_beginDragLocation!, to: supernode!.supernode!.view)
//supernode!.supernode!.view.addSubview(draggedView) // Causes immeditate cancelled.
// The following does work(ish), however, it detaches the relaion between the CALayer and the UIView.
// So from that point, I cannot directly manipulate neither the view nor the layer (since the view reference is gone).
supernode!.supernode!.layer.addSublayer(draggedView.layer)
// draggedView.center = _beginDragLocation! // not working
// self.style.layoutPosition = _beginDragLocation! // not working either
// self.setNeedsLayout()
// self.setNeedsDisplay()
case .changed:
let translation = panGesture.translation(in: self.supernode!.supernode!.view)
// draggedView.center = CGPoint(x: _beginDragLocation!.x + translation.x, y: _beginDragLocation!.y + translation.y) // when applited, it does cause the node to change position.
case .cancelled:
print("cancelled!")
default:
print("default!")
}
}
