Hello,

In (UIView_) copyOfView:(UIView_) viewToCopy function { ...

NSData* viewCopyData = [NSKeyedArchiver archivedDataWithRootObject:viewToCopy];
    UIView* viewCopy = [NSKeyedUnarchiver unarchiveObjectWithData:viewCopyData];

... } , i am having this issue: " [NSKeyedUnarchiver decodeBoolForKey:]: value for key (UIHighlighted) is not a boolean' ".... Its happening when i DOUBLE TAP on my item AND THEN try TO DRAG

After little research, some people fixed the problem with unsetting Highlighted but its not working for me....

Please, how i have to implement some double Tap function for ignoring double tap.

I have followed the I32RearrangeableExchangeableTablesViewController and when I reorder it crashes. Assuming my fault but not sure where to start looking. Tried debugging but still not seeing clear root cause.

I see it stating "This view probably hasn't received initWithFrame: or initWithCoder:" but not exactly sure what that means. My app was initially implemented back in 2011, so perhaps a version issue (ARC, or something to that effect).

Here is the debugger output with error below.

If you have any insights, would be much appreciated. This is a really great time saver for me. Thanks for putting it together and making it available.

As the delegate protocol does not include a parameter for the helper class that sent the delegate message, there is no way of implementing delegates for multiple helpers in a single class. Here is an example of what we need:

-(void) dragFromDstAtIndex:(NSIndexPath*) from toSrcAtIndex:(NSIndexPath*) to fromHelper:(I3DragBetweenHelper*) sender{

    if(sender == self.helper1){

       // Helper 1 impl
    }
    else if(sender == self.helper2){

      // Helper 2 impl
    }

}

...vs what we have at the moment:

-(void) dragFromDstAtIndex:(NSIndexPath*) from toSrcAtIndex:(NSIndexPath*) to{

    // How can I tell if this message was sent form helper1 or helper2?
}

This is currently being implemented in the delegate-refactor branch

Objectives

The main objective for V2 is to act upon the feedback given thus far in order to bring the codebase from just a helper class to a proper user interface framework.

• Testabillity
  • We now have active users and contributors. Automated tests will help us to review third party PRs, pick up regressions more easily, increase user confidence in the framework's stability and ultimately help standardise our maintenance approach.
  • We want all components of this framework to be coverable by unit tests. This will probably mean refactoring some core components to be more loosely coupled from UIKit in order to separate out the testable business logic.
  • For this release we will aim for 80% test coverage.
  • PRs from third parties must be covered my proper unit tests.
  • We will also endeavour to release some functional tests with the library, but unit tests are higher priority.
  • CI environment? Travis?
• Integration
  • Apple provides some drag-drop-ability (UITableViewRow moveable and editable properties). This framework needs to work alongside, and integrate with, these vendor-provided features.
  • This is so that users can start using the library in applications that use the built-in UIKit features.
• Help
  • People need more classes, provided by the framework, that help them meet their requirements.
  • Namely helpers for CoreData...
• Documentation
  • Documentation around contribution, change-logs, etc, is lacking.
  • This will help to standardise third party contributions and general development practices, as well as providing more transparency for users of the framework.

Plan

Phase 1

• Migrate the drag-n-drop routing logic into its own, isolated class
• Allow for the gesture listener to be injected to this class
• Create a manager-type class to register draggable components against and coordinate how the gesture recogniser is configured and injected
• Should fix #5, #6, #14,
• Should allow for #11
• Should pave the way for #7, #16, #22

Phase 2

• Review the plan
• #8
• #23
• #15
• #12
• #29

Phase 3

• Preview the plan
• _TODO... _

Timeframes

Currently I am aiming to dedicate 1, 8 hour day per week to this project (probably on a Sunday).

I thought it was not as intuitive to force the user to drop the first item at the very top on an empty table, so I made some mods that I think could improve the UX but I am not certain if there are any negative repercussions as I have not done extensive testing, yet, but so far it looks good. Here's what I did.

In I3DragBetweenHelper, I commented out lines 792 - 797 (if nil check on drop index) https://github.com/ice3-software/i3-dragndrop/blob/master/Classes/I3DragBetweenHelper.m#L792

Then in the delegate method, droppedOnDstAtIndexPath:to fromSrcIndexPath:from, I check for index==nil and just create a new NSIndexPath with row set to the size of the datasource of the target table. I have to do the same in the srcTable as I did in the dstTable, obviously.

if (to == nil)
{
    to = [NSIndexPath indexPathForRow:(self.dstDataSource.count) inSection:0];
}

Hope this can make it into your sources as feature if you see it as useful.

Including nil drop indexes when a drop event occurs lets the user drag and drop a cell into an empty Collection/Table VC.

I'm using the draggingView handler to detect when a cell is in a hover state over the destination view.

On iOS 6, if you subclass UITableViewCell or UICollectionViewCell and add subviews as properties to your custom cell they are issues with the duplicate dragging cell - the new subviews that you've added are usually not encoded/decoded for the duplicate dragging view. At present you must implement your own archiving mechanism in the subclass for your custom cell subviews.

I will provide examples on how to do this shortly.

This might not be that big a deal but in my case, I don't want the tables to scroll with single touch. So I disable single finger/touch scroll and force 2 finger scrolling. This has a side effect of allowing drag in any direction to initiate the DnD.

Just do the following in viewDidLoad: self.myLeftSideTable.panGestureRecognizer.minimumNumberOfTouches = 2;

Once I have one item in the dst table, I can DnD without issue. But am unable to add that first item with DnD. I also cannot DnD a cell so that I drop it at the bottom of the table (as the last row in the table) - maybe related?

Again, love this DnD solution. So easy to implement using your helper and example code. Kudos!

Currently, rearrange swaps the drag indexPath with the drop indexPath. It would be useful if the DnD could be optionally configured to just reorder the all indexPaths above the drop by -1.

While using this I3DragBetweenHelper code for rearranging rows in the same table view, app get crashed in the line (+[NSKeyedArchiver archivedDataWithRootObject:]) with exception as follows,

Hello.

https://github.com/ice3-software/between-kit/blob/master/Docs/Usage.md

#import <BetweenKit/UITableView+I3Collection.h> #import <BetweenKit/I3DragArea.h>

Gives error: 'BetweenKit/I3DragArea.h' file not found.

#import <BetweenKit/UITableView+I3Collection.h> #import <BetweenKit/I3DragArena.h>

Work correct.

To get drag events while dragging, I used I3DragRenderDelegate. But after implementing the delegate, the snapshot view is not rendered. Why do I need to implement all the methods if I implement I3DragRenderDelegate? How will I get a snapshot view?

The numbering scheme was originally meant to achieve tutorial-like ordering. The ordering of difficulty can easily be expressed in the Getting Started doc.
