单击图像时,如何将包含图像集内视图的视图控制器传递给另一个视图控制器?因此,当我单击图像时,它会在另一个视图控制器中打开。
cellForItemAtIndexPath代码:
func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell
{
let cell = collectionView.dequeueReusableCellWithReuseIdentifier("cell", forIndexPath: indexPath) as! CollectionViewCell
cell.imageText.adjustsFontSizeToFitWidth = true
cell.layer.borderWidth = 0.5
cell.layer.cornerRadius = 3
let myColor : UIColor = UIColor(red: 0.0, green: 0.0, blue:0.0, alpha: 0.15)
cell.backgroundColor = UIColor(red: 0.0, green: 0.0, blue: 0.0, alpha: 0.025)
cell.layer.borderColor = myColor.CGColor
let post = self.arrayOfDetails[indexPath.row]
cell.currentUserLabel.text = post.username
cell.imageText.text = post.text
cell.uploadedTimeLabel.text = post.CreatedAt.timeAgo
cell.imageView.setImageWithUrl(NSURL(string: post.image)!, placeHolderImage: UIImage(named: "Placeholder"))
return cell
}
详细说明:
struct Details {
var username:String!
var text:String!
var CreatedAt:NSDate!
var image:String!
init(username:String,text:String,CreatedAt:NSDate,image:String){
self.username = username
self.text = text
self.CreatedAt = CreatedAt
self.image = image
}
}
didSelectItemAtIndexPath方法:
func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath)
{
self.performSegueWithIdentifier("showImage", sender: self)
}
有什么建议吗?
答案 0 :(得分:0)
根据您使用故事板或以编程方式进行操作,我会以同样的方式进行操作:
在新VC中设置您可以公开访问的属性,然后在prepareForSegue或您的委托方法中单击单元格,将所需信息传递到新VC的属性中,然后在viewDidLoad
,viewWillAppear
等中设置您需要的所有数据。
最简单的解决方案当然是传入imageView,但它可能不是正确的分辨率等。因此,传递在prepareForSegue
或didSelectItem
中重新创建所需的任何数据方法,并在新VC中使用它
