Ich entwickle eine App, die UICollectionView wie # zhangao0086/DKImagePickerController # Beispiel in Github hat. Jetzt muss ich die angezeigten UICollectionviewCell Bilder auf den Server hochladen. Kann mir jemand die richtigen Tuts zum Hochladen vorschlagen? Danke im Voraus.hochladen Sammlung Bilder in Server mit swift
UICollectionView Code wie folgt:
func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
let asset = self.assets![indexPath.row]
var cell: UICollectionViewCell?
var imageView: UIImageView?
if asset.isVideo {
cell = collectionView.dequeueReusableCellWithReuseIdentifier("CellVideo", forIndexPath: indexPath)
imageView = cell?.contentView.viewWithTag(1) as? UIImageView
} else {
cell = collectionView.dequeueReusableCellWithReuseIdentifier("CellImage", forIndexPath: indexPath)
imageView = cell?.contentView.viewWithTag(1) as? UIImageView
}
if let cell = cell, imageView = imageView {
let layout = collectionView.collectionViewLayout as! UICollectionViewFlowLayout
let tag = indexPath.row + 1
cell.tag = tag
asset.fetchImageWithSize(layout.itemSize.toPixel(), completeBlock: { image, info in
if cell.tag == tag {
imageView.image = image
}
})
}
return cell!
}
