 1 | ReorderableGridView-Swift
 2 | =======================
 3 | 
 4 | reorderable grid view solution implemented with swift. <br>
 5 | its UIScrollView subclass, its not a collection view layout.<br>
 6 | automatically sets horizontal item spacing by item widths. so items must be fixed-width.<br>
 7 | also sets automatically its content size. <br>
 8 | if you call `gridView?.invalidateLayout()` after orientation changed, it will lays out the grid by new orientation.

11 | Demo
12 | ----
13 | 
14 | ![alt tag](https://raw.githubusercontent.com/cemolcay/ReordableGridView-Swift/master/demo.gif)
15 | 
16 | Usage
17 | -----
18 | 
19 | copy & paste the `ReorderableGridView.swift` into your project. <br>
20 | 
21 |       gridView = ReorderableGridView(frame: self.view.frame, itemWidth: 180, verticalPadding: 20)
22 |       self.view.addSubview(gridView!)
23 | 
24 | Grid view ready !
25 | 
26 | now you can add it `ReorderableView` instances 
27 |       
28 |       let itemView = ReorderableView (x: 0, y: 0, w: 180, h: 250)
29 |       ...
30 |       gridView?.addReorderableView(itemView)
31 |       
32 |       // or
33 |       let pos = GridPosition (x: 0, y: 1)
34 |       gridView?addReorderableView (itemView, gridPosition: pos)
35 | 
36 | 
37 | 
38 | or  remove them
39 | 
40 |     gridView?.removeReorderableViewAtGridPosition(GridPosition (x: 0, y: 0))
41 |     
42 |     // or
43 |     gridView?.removeReorderableView (itemView)
44 | 
45 | 
46 | > **Design Tip**  
47 | > View itself don't have any margin padding.  
48 | > It uses all frame width to calculate how many `ReorderableView`s can fit and
49 | > what should be their horizontal padding in a row.   
50 | > Padding between columns (vertical padding) can be set in init method,    
51 | > which is 10 by default.  
52 | > You can have a container view and use something like   
53 | > `CGRectInset (containerView.frame, marginX, marginY)`  
54 | > when init grid with margin
55 |

58 | Optional Values
59 | ---------------
60 | 
61 |       var reorderable : Bool = true
62 |       var draggable : Bool = true
63 |       var draggableDelegate: Draggable?
64 | 
65 | set them if you want your grid editable or not
66 | 
67 | **Draggable Protocol**
68 | 
69 |     func didDragStartedForView (reorderableGridView: ReordableGridView, view: ReordableView)
70 |     func didDraggedView (reorderableGridView: ReordableGridView, view: ReordableView)
71 |     func didDragEndForView (reorderableGridView: ReordableGridView, view: ReordableView)
72 | 
73 | 
74 | set `gridView.draggableDelegate = self` and implement `Draggable` protocol functions if you want to access info about dragging actions in grid.   
75 | This can be useful for multiple grid layouts.  
76 | Example included in second tab of demo.
