Sort UIViews with UIPanGestureRecognizer. Receive delegate notifications for the positions of moved views and swapped views. Useful for games, pickers, settings, and menus.
- Xcode 4.5 or higher
- Apple LLVM compiler
See this tutorial for an explanation of how I put it together and what I use it for.
Drag the 'MELSortingView' folder into your project. Make sure 'Copy items if needed' and 'Create groups' is checked.
Add the object to your view controller specifying the x and y offsets, the width, and the number of sortable views that you need. You can also add numbered labels. To stay in tune with Apple's Human Interface Guidelines, the view must be at least 100px wide.
MELSortingView *sortView = [MELSortingView sortingViewWithFrame:CGRectMake(0, 0, view.width, view.height) forView:view numberOfViews:6];
sortView.delegate = self;
NSArray *labels = @[@"0", @"1", @"2", @"3", @"4", @"5"];
[sortView setLabels:labels];
[self.view addSubview:sortView];Receive delegate notifications whenever a view is moved or two views have swapped places. These methods tell you the positions of the moving views from 0..n.
