So I have a main object that has many images associated with it. An Image is also an object.
Say you have a collection view controller, and in that controller you have
cellForItemAtIndexPath
well based on the main object, if it has the current image associated with it I want to set selected to true. But I want the user to be able to "un-select" that current cell at any time to remove its association with the main object.
I find that if you set "selected to true" - if there is an relation between the main object and image in cellForItemAtIndexPath
, de-selection is no longer an option.
in
didDeselectItemAtIndexPath
and
didSelectItemAtIndexPath
I test with a log to see if they are called. If a cell is set to selected - nether gets called, but If I never set a cell to selected in cellForItemAtIndexPath
I can select and deselect all I want.
Is this the intended way a collection view is supposed to work? I read the docs and it does not seem to talk about this being so. I interpret the docs to mean it works the way a table view cell would. with a few obvious changes
This also shows the controller is set up correct and is using the appropriate delegate methods.... hmmmm
I had the same issue, ie. setting cell.selected = YES
in [UICollectionView collectionView:cellForItemAtIndexPath:]
then not being able to deselect the cell by tapping on it.
Solution for now: I call both [UICollectionViewCell setSelected:]
and [UICollectionView selectItemAtIndexPath:animated:scrollPosition:]
in [UICollectionView collectionView:cellForItemAtIndexPath:]
