我有一个基本的收集视图,该视图是彩色网格。我要做的就是在网格单元格中添加一个文本标签。在情节提要中,我已将标签拖动到单元格的内容视图内。我已经在控制整个集合的视图控制器中为此标签创建了一个出口。但是以某种方式我无法设置此视图控制器内单元格的文本。我该怎么办?
import UIKit
let reuseIdentifier = "CellIdentifer";
class WordsViewController: UIViewController, UICollectionViewDataSource, UICollectionViewDelegate, UICollectionViewDelegateFlowLayout {
@IBOutlet var collectionView: UICollectionView!
@IBOutlet weak var textLabel: UILabel!
@IBOutlet var cellView: UIView!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
//UICollectionViewDelegateFlowLayout methods
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, minimumLineSpacingForSectionAt section: Int) -> CGFloat
{
return 4;
}
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, minimumInteritemSpacingForSectionAt section: Int) -> CGFloat
{
return 1;
}
//UICollectionViewDatasource methods
func numberOfSectionsInCollectionView(collectionView: UICollectionView) -> Int {
return 1
}
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return 100
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: reuseIdentifier, for: indexPath as IndexPath) as UICollectionViewCell
cell.backgroundColor = self.randomColor()
return cell
}
// custom function to generate a random UIColor
func randomColor() -> UIColor{
let red = CGFloat(drand48())
let green = CGFloat(drand48())
let blue = CGFloat(drand48())
return UIColor(red: red, green: green, blue: blue, alpha: 1.0)
}
}

created an outlet for this label inside the view controller
如果您想在每个单元格中都有一个文本,则不能这样做。相反,您想要做的是将UICollectionViewCell子类化(例如CustomCollectionViewCell)。将情节提要中的collectionViewCell设置为此类,然后连接标签。现在,您可以像这样设置文本:
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: reuseIdentifier, for: indexPath as IndexPath) as CustomCollectionViewCell
cell.backgroundColor = self.randomColor()
cell.myShinyNewTextLabel.text = "myCustomText"
return cell
}
