ios – 使用UIImagePickerController访问照片库后崩溃

概述点击按钮时访问照片库时遇到麻烦.像往常一样,我在问它是否可以访问.以下是我的代码 @IBAction func photoLibraryButtonTapped(sender: UIButton) { if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.PhotoLi 点击按钮时访问照片库时遇到麻烦.像往常一样,我在问它是否可以访问.以下是我的代码

@IBAction func photolibrarybuttonTapped(sender: UIbutton) {        if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.Photolibrary) {            let imagePicker = UIImagePickerController()            imagePicker.delegate = self            imagePicker.sourceType = UIImagePickerControllerSourceType.Photolibrary            imagePicker.allowsEditing = true            self.presentVIEwController(imagePicker,animated: true,completion: nil)        }    }

这是Xcode所说的：

解决方法 1.请检查视图控制器和故事板文件的目标应该在同一目标中.
2.选择您的xib并删除映射到该故事板的类并将其映射回来,并在粘贴您的类后按Enter键,您的笔尖名称保持相同以进行测试.
3.如果此按钮正在加载表单自定义视图,则视图控制器需要检查自定义视图是否已添加到右目标,并再次使用ibaction重新映射内部.

通过查看您的对话,我可以解决这个问题.
