[英]I have the cell displayed but I want the image to be displayed in the collection view cell when i press the button
I want to insert images from array when I press the button 我想在按下按钮时从数组中插入图像
func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCellWithReuseIdentifier("Cell", forIndexPath: indexPath)
cell.backgroundColor = UIColor.orangeColor()
return cell
}
func buttonCreateStickerPressed(sender: UIButton!){
let stickerName = "Sticker Number "+String(stickerDictionary.count+1)
let stickerNumber = stickerDictionary.count+1
makeSticker(stickerName, stickerNumber: stickerNumber)
// let count = stickerArray.count
}
您可以尝试reloadData然后设置图像,或者如果只对某些索引进行设置,则可以尝试reloadDataForRowIndexes:columnIndexes然后在选定的行中设置图像
