DDCalendarView

• a calendar view that looks like the ical view. It supports drag and drop
• the 2 demos (objc and swift) show to use & customise it
• it can easy be used to show and modify EKEvents - ios native calendar store and can be combined with EventKitUI
• The view can be used for storyboarding and is IBDesignable and also partly IBInspectable so you can 'preview' it in IB
• The view has extensive delegate & dataSource support so it feels like working with UITableViews. Have fun and please share additions you make

demo at cocoacontrols

cocoacontrols has a live demo of the control where you can try out d&d and see how it handles multiple events at the same time:
