让我简要介绍一下我的项目，我正在显示照片库中的图像，我的视图控制器中有 Imageview 和按钮，当我按下按钮时，当我从库中选择照片时，它将导航到照片库图像将在图像视图中显示。

但是当我运行这个项目时，我遇到了运行时错误，请查看代码并建议我解决方案，如果缺少任何文件，请通知我，以便我可以上传您的需要。

我没有得到错误的确切位置，我用谷歌搜索，甚至看到堆栈溢出我仍然找不到任何解决方案

以下是 Viewcontroller.m 文件和控制台查看错误，请告诉我

在您的ViewController.xib中，选择您的图像视图并检查IBOutlet Connections. 如果它连接到IBOutlet命名的image，请将其删除。您的图像视图应连接到IBOutlet相应.h文件中的图像视图。您可能已重命名UIImageView为imagePic以前image的 .
