UICollectionView Moving

I followed the directions here, http://nshint.io/blog/2015/07/16/uicollectionviews-now-have-easy-reordering/ - to add iOS9 style dragging to my UICollectionView - and it sort of works. As described in the article, I added a long press gesture recognizer and wired it in to make calls on the collect

Re: UICollectionView Moving

I’d check your return value for this method in your layout: - (UICollectionViewLayoutAttributes *)layoutAttributesForInteractivelyMovingItemAtIndexPath:(NSIndexPath *)indexPath withTargetPosition:(CGPoint)position NS_AVAILABLE_IOS(9_0); Luke On Mar 7, 2016, at 9:55 AM, Luther Baker mailto:lut

Re: Returning a string value from a c function to a Objective-C class method. Is there an approved approach?

Just a formal note: You guys are awesome. THANK YOU. I've got a .m file that serves as a C and Objective-C layer (glue layer?) to the library methods. In it, I have one id that is the reference back to the object itself. Each static C function that returns data, constructs an Objective-C frie

Re: UICollectionView Moving

Thanks Luke! That was it - I can drag and drop successfully now. One more question, how do I modify a property of the item I'm dragging around if the property is NOT currently in UICollectionViewLayoutAttributes ... I don't see a call to the datasource or delegate when I select the cell for moving

Re: UICollectionView Moving

You can create your own subclass of UICollectionViewLayoutAttributes and add something like an “isMoving” property to that. Then teach your cell classes to respond to that property by changing the background color. Luke On Mar 7, 2016, at 11:44 AM, Luther Baker mailto:lutherba...@gmail.com>> w

Re: UICollectionView Moving

> teach your cell classes to respond to that property Want to think about this out loud. Wondering what would 'trigger' a lookup on the layout's layoutAttributesForItemAtIndexPath ... and where would I store the indexPath I am dragging around. If I were to be more literal - in my view controller,

Re: UICollectionView Moving

By teaching a cell to respond to an attribute I merely meant that it should override setLayoutAttributes: and do something in there with the relevant property. Hope that helps. Luke On Mar 7, 2016, at 9:39 PM, Luther Baker mailto:lutherba...@gmail.com>> wrote: > teach your cell classes to res
