Hey Stephen, found this resource on Udemy, describes setting up the panGesture functionality to drag and drop Pictures on a screen.

Added code for dragging objects. Phone detects the object by prioritizing drag gesture. However image has yet to be extracted to show movement.

@szeng2013 have you tried the Udemy method?

szeng2013 commented 10 years ago

That's the first thing I tried. It doesn't apply due to the fact that we use a collection view to view ALL album images rather individual images populated one at a time.

Update on drag and drop: Spent 4 hours implementing drag and drop. Tried using UIPanGesture and UILongPressGesture libraries as well as open source helper object dragging functions. Image thumbnail will not populate but the dragging gesture is detected.
