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!

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.
其他提示
you can use this method [UIView removeFromSuperView];
