Swift:从自定义单元启动相机

Question

我有一个自定义单元格，里面有一个按钮。点击该按钮后，我想启动相机。

自定义单元格 Xib:

//自定义按钮单元格类代码:

import UIKit

class CameraCell: UITableViewCell, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
    @IBOutlet weak var buttonCamera: UIButton!

    required init(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
    }

    override func awakeFromNib() {
        super.awakeFromNib()
    }

    override func setSelected(selected: Bool, animated: Bool) {
        super.setSelected(selected, animated: animated)

        // Configure the view for the selected state
    }

    @IBAction func buttonCameraTapped(sender: UIButton) {

    if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.Camera) {

    let imagePicker = UIImagePickerController()

    imagePicker.delegate = self
    imagePicker.sourceType = UIImagePickerControllerSourceType.Camera
    imagePicker.mediaTypes = [kUTTypeImage]
    imagePicker.allowsEditing = false

    self.presentViewController(imagePicker, animated: true,
    completion: nil)
    //This 'CameraCell' does not have a member named 'presentViewController'
        }
    }

错误:这个“CameraCell”没有名为“presentViewController”的成员

我还需要一个委托(delegate) (UIImagePickerControllerDelegate) 来处理拍照后的事件。

如何从自定义单元格内的按钮启动相机并将其设置为相机代理？

Answer 1

因为你是UITableViewCell的子类，怎么调用presentViewController。只有 UIViewController 可以调用它。

我要做的是在您处理单元格的 UIViewController 中处理 UIImageViewController 的触发器。
