Question

我一直在尝试将一系列标签添加到我的收藏视图单元格中，但它们没有显示出来。

import UIKit

class HomeMenuViewController: UIViewController, UICollectionViewDataSource, UICollectionViewDelegate {

var codes = ["NBA","NFL","Girls","Rappers","Celebrities","NFL Teams","Travel","Models","Foodies","Musician","Companies/Brands","Youtube/Viral Stars","Fitness","Snapchat Art","Fashion/Makeup", "MLB Teams"]

var images = [UIImage(named: "title617792344"),UIImage(named: "title236271662"),UIImage(named: "title713937166"),UIImage(named: "title718520594"),UIImage(named: "title205571580"),UIImage(named: "title193064553"),UIImage(named: "title800939906"),UIImage(named: "title987804505"),UIImage(named: "title528311821"),UIImage(named: "title673858816"),UIImage(named: "title543192229"),UIImage(named: "title351533554"),UIImage(named: "title311505831"),UIImage(named: "title579492173-1"), UIImage(named: "title743923696"),UIImage(named: "title544380635")]

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.
}

 func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
    return 16
}

 func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {

    var cell = collectionView.dequeueReusableCell(withReuseIdentifier: "uicvcell", for: indexPath) as! HomeMenuCollectionViewCell

    var image = cell.viewWithTag(1) as! UIImageView

    image.image = images[indexPath.row]

    var code = cell.viewWithTag(2) as! UILabel

    code.text = codes [indexPath.row]

    return cell
}

 func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
    if(indexPath.row == Int("0")){
        performSegue(withIdentifier: "0", sender: nil)
    }
    else if(indexPath.row == Int("1")){
        performSegue(withIdentifier: "1", sender: nil)
    }
    else if(indexPath.row == Int("2")){
        performSegue(withIdentifier: "2", sender: nil)
    }
    else if(indexPath.row == Int("3")){
        performSegue(withIdentifier: "3", sender: nil)
    }
    else if(indexPath.row == Int("4")){
        performSegue(withIdentifier: "4", sender: nil)
    }
    else if(indexPath.row == Int("5")){
        performSegue(withIdentifier: "5", sender: nil)
    }
    else if(indexPath.row == Int("6")){
        performSegue(withIdentifier: "6", sender: nil)
    }
    else if(indexPath.row == Int("7")){
        performSegue(withIdentifier: "7", sender: nil)
    }
    else if(indexPath.row == Int("8")){
        performSegue(withIdentifier: "8", sender: nil)
    }
    else if(indexPath.row == Int("9")){
        performSegue(withIdentifier: "9", sender: nil)
    }
    else if(indexPath.row == Int("10")){
        performSegue(withIdentifier: "10", sender: nil)
    }
    else if(indexPath.row == Int("11")){
        performSegue(withIdentifier: "11", sender: nil)
    }
    else if(indexPath.row == Int("12")){
        performSegue(withIdentifier: "12", sender: nil)
    }
    else if(indexPath.row == Int("13")){
        performSegue(withIdentifier: "13", sender: nil)
    }
    else if(indexPath.row == Int("14")){
        performSegue(withIdentifier: "14", sender: nil)
    }
    else if(indexPath.row == Int("15")){
        performSegue(withIdentifier: "15", sender: nil)
    }
    else if(indexPath.row == Int("16")){
        performSegue(withIdentifier: "16", sender: nil) }
    else if(indexPath.row == Int("17")){
        performSegue(withIdentifier: "17", sender: nil)
    }
    else if(indexPath.row == Int("18")){
        performSegue(withIdentifier: "18", sender: nil)



    }


}
}

这是我的另一个文件，其中包含IBOutlets。

导入UIKit

class HomeMenuCollectionViewCell: UICollectionViewCell {

   @IBOutlet weak var codes: UILabel!
   @IBOutlet weak var image: UIImageView!


}

我能够在UICollection视图控制器中执行此操作，但现在我在视图控制器中添加它不起作用。

Answer 1

DECLARE @tbl AS TABLE([rn] INT IDENTITY(1, 1), [id] INT);
INSERT INTO @tbl([id]) VALUES(5), (64), (2), (8), (7), (1);

SELECT t1.*
FROM [your_table_name] t1
JOIN @tbl t2
ON t1.[id] = t2.[id]
ORDER BY t2.[rn];

并将其与主故事板中的收藏夹视图和

连接

在@IBOutlet weak var yourCollectionView:UICollectionView!方法中添加以下行

ViewDidLoad

Answer 2

<c:url value="/students/add" var="addStudentAction"></c:url>
<form action="${addStudentAction}" method="get">
    <input type="hidden" name="studentId">
    <input type="text" name="studentName"></input>
    <input type="submit" name="submit" value="Add Student" />
</form>

为什么你需要设置标签并使代码复杂化，但是这将显示标签，你将获得所需的输出

标签不出现在UICollectionView单元格上方
