arrays - 从indexpath.row中的数组获取特定值

Question

我正在尝试从汽车制造数组中获取第二个和第三个值并返回到下面的函数中。我努力了cell.title.text = carmake[1...2][indexPath.row] 和 cell.title.text = carmake[indexPath.[1...2]] code> 但没有一个是正确的。请帮助我

carmake = ["hi","hello","how are you","i am good"]

func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
  let cell = viewcontrol.dequeueReusableCellWithReuseIdentifier("cell", forIndexPath: indexPath) as! jobtypeCollectionViewCell

  cell.title.text = carmake[indexPath.row]
  return cell
}

Answer 1

如果你想组合它们，你可以尝试:

cell.title.text = carmake[1] + carmake[2]
