Ios 将数据从ViewController传递到表格单元格内的集合单元格

这可能有点混乱，但我有一个视图控制器，它有一个包含自定义表单元格的表视图，在这个表单元格中，我有一个collectionView，每个单元格都有一个图像。我试图使用下面的userToView变量配置collectionCell的映像

下面的委托函数是配置表格单元格的位置：

OtherUserAccountViewController.swift

class OtherUserAccountViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {

    var userToView = User() 

...

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

        let cell:OtherUserPhotosTableViewCell = self.tableView.dequeueReusableCell(withIdentifier: photosCellReuseIdentifier) as! OtherUserPhotosTableViewCell
        cell.selectionStyle = .none

        return cell
    }
...

}

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "otherUserPhotosCollectionCell", for: indexPath) as! OtherUserPhotosCollectionViewCell
    //Configure cell with photo from parent ViewController
    return cell
}

class OtherUserPhotosCollectionViewCell: UICollectionViewCell {

    @IBOutlet weak var imageView: UIImageView!
}

下面的委托函数是设置此图像的位置：

OtherUserPhotosTableViewCell.swift

class OtherUserAccountViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {

    var userToView = User() 

...

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

        let cell:OtherUserPhotosTableViewCell = self.tableView.dequeueReusableCell(withIdentifier: photosCellReuseIdentifier) as! OtherUserPhotosTableViewCell
        cell.selectionStyle = .none

        return cell
    }
...

}

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "otherUserPhotosCollectionCell", for: indexPath) as! OtherUserPhotosCollectionViewCell
    //Configure cell with photo from parent ViewController
    return cell
}

class OtherUserPhotosCollectionViewCell: UICollectionViewCell {

    @IBOutlet weak var imageView: UIImageView!
}

我的自定义CollectionViewCell如下所示：

OtherUserPhotosCollectionViewCell.swift

class OtherUserAccountViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {

    var userToView = User() 

...

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

        let cell:OtherUserPhotosTableViewCell = self.tableView.dequeueReusableCell(withIdentifier: photosCellReuseIdentifier) as! OtherUserPhotosTableViewCell
        cell.selectionStyle = .none

        return cell
    }
...

}

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "otherUserPhotosCollectionCell", for: indexPath) as! OtherUserPhotosCollectionViewCell
    //Configure cell with photo from parent ViewController
    return cell
}

class OtherUserPhotosCollectionViewCell: UICollectionViewCell {

    @IBOutlet weak var imageView: UIImageView!
}

在过去的几周里，我才真正习惯了Swift&iOS的开发，因此非常感谢您的帮助。谢谢你抽出时间

假设您已有可用的

假设您有一个UICollectionViewCell

在

OtherUserPhotosTableViewCell.swift中

var photoFromTableView: UIImage?    

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "otherUserPhotosCollectionCell", for: indexPath) as! OtherUserPhotosCollectionViewCell
    //Configure cell with photo from parent ViewController
    if let photo:UIImage = photoFromTableView {
        cell.imageView.image = photo
    }
    return cell
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

    let cell:OtherUserPhotosTableViewCell = self.tableView.dequeueReusableCell(withIdentifier: photosCellReuseIdentifier) as! OtherUserPhotosTableViewCell
    cell.selectionStyle = .none
    cell.photoFromTableView = //Image you want to pass
    return cell
}

var photosArray: [UIImage]?    

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "otherUserPhotosCollectionCell", for: indexPath) as! OtherUserPhotosCollectionViewCell
    //Configure cell with photo from parent ViewController
    if let photo_array:[UIImage] = photosArray {
        cell.imageView.image = photo_array[IndexPath.row]
    }
    return cell
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

    let cell:OtherUserPhotosTableViewCell = self.tableView.dequeueReusableCell(withIdentifier: photosCellReuseIdentifier) as! OtherUserPhotosTableViewCell
    cell.selectionStyle = .none
    cell.photosArray = //Array of Images you want to pass
    return cell
}

在
OtherUserAccountViewController.swift中

var photoFromTableView: UIImage?    

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "otherUserPhotosCollectionCell", for: indexPath) as! OtherUserPhotosCollectionViewCell
    //Configure cell with photo from parent ViewController
    if let photo:UIImage = photoFromTableView {
        cell.imageView.image = photo
    }
    return cell
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

    let cell:OtherUserPhotosTableViewCell = self.tableView.dequeueReusableCell(withIdentifier: photosCellReuseIdentifier) as! OtherUserPhotosTableViewCell
    cell.selectionStyle = .none
    cell.photoFromTableView = //Image you want to pass
    return cell
}

var photosArray: [UIImage]?    

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

    //Configure cell with photo from parent ViewController
    if let photo_array:[UIImage] = photosArray {
        cell.imageView.image = photo_array[IndexPath.row]
    }
    return cell
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

    let cell:OtherUserPhotosTableViewCell = self.tableView.dequeueReusableCell(withIdentifier: photosCellReuseIdentifier) as! OtherUserPhotosTableViewCell
    cell.selectionStyle = .none
    cell.photosArray = //Array of Images you want to pass
    return cell
}

假设您有多个UICollectionViewCell

    //Configure cell with photo from parent ViewController
    if let photo:UIImage = photoFromTableView {
        cell.imageView.image = photo
    }
    return cell
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

    cell.selectionStyle = .none
    cell.photoFromTableView = //Image you want to pass
    return cell

    //Configure cell with photo from parent ViewController
    if let photo_array:[UIImage] = photosArray {
        cell.imageView.image = photo_array[IndexPath.row]
    }
    return cell
}

    let cell:OtherUserPhotosTableViewCell = self.tableView.dequeueReusableCell(withIdentifier: photosCellReuseIdentifier) as! OtherUserPhotosTableViewCell
    cell.selectionStyle = .none
    cell.photosArray = //Array of Images you want to pass
    return cell
}

在
OtherUserAccountViewController.swift中

var photoFromTableView: UIImage?    

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

    //Configure cell with photo from parent ViewController
    if let photo:UIImage = photoFromTableView {
        cell.imageView.image = photo
    }
    return cell

    let cell:OtherUserPhotosTableViewCell = self.tableView.dequeueReusableCell(withIdentifier: photosCellReuseIdentifier) as! OtherUserPhotosTableViewCell

userToView
变量包含什么？你从哪里获得图像？正确，我将使用UIImages数组非常感谢！！
