ios - 在表格 View 中显示从相机拍摄的照片

Question

我发现了一些类似的问题，但没有回答我的问题。我希望用户选择一个表格单元格，打开相机，拍照，然后将照片加载到表格单元格的 imageView 中。到目前为止，这是我的代码片段。我只是不知道如何将这张照片添加到表格单元格中。谢谢!

 func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]){
    imagePicker.dismissViewControllerAnimated(true, completion: nil)
    var photo = info[UIImagePickerControllerOriginalImage] as? UIImage
}

func numberOfSectionsInTableView(tableView: UITableView) -> Int {
    return 1
}

func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return bedroomCells.count
}

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

    let cell = tableView.dequeueReusableCellWithIdentifier(textCellIdentifier, forIndexPath: indexPath) as UITableViewCell

    let row = indexPath.row
    cell.textLabel?.text = bedroomCells[row]
    //cell.imageView?.image =
    return cell
}

试试这个，似乎对我有用:

class ExampleTableViewController: UITableViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {

    struct TestStruct {
        var text: String?
        var image: UIImage?
    }

    var imagePicker = UIImagePickerController()
    var bedroomCells = [TestStruct]()
    var lastSelectedIndex: NSIndexPath?
    override func viewDidLoad() {
        super.viewDidLoad()
        imagePicker.delegate = self
        for var i = 0; i < 10 ; i++ {
            var entry = TestStruct(text: "\(i)", image: nil)
            bedroomCells.append(entry)
        }
    }

    override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return bedroomCells.count;
    }


    override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

        let cell = tableView.dequeueReusableCellWithIdentifier("sampleCell", forIndexPath: indexPath) as UITableViewCell
        cell.textLabel?.text = bedroomCells[indexPath.row].text
        cell.imageView?.image = bedroomCells[indexPath.row].image

        return cell
    }


    override func tableView(tableView: UITableView, didDeselectRowAtIndexPath indexPath: NSIndexPath) {
        self.lastSelectedIndex = indexPath // Save the selected index
        self.presentViewController(imagePicker, animated: true, completion: nil)
    }


    func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]) {
        imagePicker.dismissViewControllerAnimated(true, completion: nil)
        var photo = info[UIImagePickerControllerOriginalImage] as? UIImage
        bedroomCells[lastSelectedIndex!.row].image = photo // Set the image for the selected index
        tableView.reloadData() // Reload table view
    }

}
