大佬教程收集整理的这篇文章主要介绍了ios – 使用UIImagePickerController访问照片库后崩溃，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

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.
