So, I have a custom UIView inside a UIScrollView. I am able to detect the touches Events in the customUIView. I am trying to drag the UIView outside the UIScrollView onto a Canvas (UIView). However, when it gets out of bounds from the SrollView, it just hides behind it? How can I overcome this? Thanks guys!
해결책
When you start dragging the view, remove it from the superview that is the UIScrollView, and make it a subview of the app's Window, and bring it to front (z-order-wise).
But first you need to calculate (convert) the dragging view's frame with regards to the window, since the coordinates will be different after changing its superview.
다른 팁
you can use this method [UIView removeFromSuperView];
