Usage

Install with CocoaPods

Call 'makeDraggable' or 'makeDraggableWithDropViews:delegate:' on a UIView or UIView subclass, set a delegate, and configure as needed


//make a view draggable
[self.view1 makeDraggable];
[self.view1 setDelegate:self];

// Set drop views with an array of UIView elements
[self.view1 setDropViews:@[..]];

// Restricts drag motion to x axis
[self.view1 setDragMode:UIViewDragDropModeRestrictX];
