uicollectionviewcell

问题 I have set up a collectionView to have custom reordering behavior via the solution here However, when a cell is quickly dragged to a new row, the animation shows the dragged cell animate from its original position again (see below): I am wondering how I could have it just drop the dragged cell at the row it's been dragged to, rather than showing it animate from its original cell again. 回答1: I have solved this well by increasing the setting the dragged cell's layer.speed property when the

问题 I am seeing some extremely odd behavior that I would like some assistance with. I have a collection view cell that originally had one label, with a tag of 43. I am setting the value of the label using the following code: func collectionView(collectionView: UICollectionView!, cellForItemAtIndexPath indexPath: NSIndexPath!) -> UICollectionViewCell! { let object = self.fetchedResultsController.objectAtIndexPath(indexPath) as NSManagedObject let cell = collectionView

问题 I have a button inside a collectionview cell that I programmatically created. @IBAction func editButtonTapped() -> Void { print("Hello Edit Button") } j func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell { let editButton = UIButton(frame: CGRect(x: 8, y: 241, width: 154, height: 37)) editButton.setImage(UIImage(named: "background-1 (dragged).tiff"), for: UIControlState.normal) editButton.addTarget(self, action: #selector

问题 tl;dr: I'm having trouble figuring out how to segue from my NewTransactionViewController back to my main CollectionViewController and when going back, adding the data from the NewTransactionViewController into my collection list view.
