所以現在我試圖讓集合視圖單元格使用照片庫來更新照片。這裏是我的代碼:試圖在UICollectionViewCell類上使用照片庫
import UIKit
class viewCellVC: UICollectionViewCell, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
@IBOutlet var bookImage: UIImageView!
@IBAction func addImage(_ sender: Any) {
let imagePicker = UIImagePickerController()
imagePicker.delegate = self
imagePicker.sourceType = UIImagePickerControllerSourceType.photoLibrary
imagePicker.allowsEditing = false
self.window?.rootViewController?.present(imagePicker, animated: true, completion: nil)
}
func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
picker.dismiss(animated: true, completion: nil)
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
let image = info[UIImagePickerControllerOriginalImage] as! UIImage
bookImage.image = image
picker.dismiss(animated: true, completion: nil)
}
}
然而,當我嘗試運行代碼,更新圖片,模擬器無法打開照片庫,而不是我收到以下錯誤消息(沒有結束的應用,只是未能運行照片庫):
2017-08-07 21:35:31.709183-0500 ChuBookElf[2817:66569] Warning: Attempt to present <UIImagePickerController: 0x7f907e0bf800> on <ChuBookElf.ViewController: 0x7f907de072c0> whose view is not in the window hierarchy!
有人可以告訴我我做錯了什麼嗎?我已經在這個幾個小時了。
For Reference, here is what the collection view cell looks like
我不知道如何從我的UICollectionViewCell形象,我的ViewController雖然。 –
