在
ProfileViewControllerupdateUserStatussetFileUIImageViewself.profileImageView.file=user[@“profilePicture”]
UIImageView（如has profileImageView）没有文件
属性，因此无法设置它。仔细检查设置文件的预期类。您在哪里调用setFile
？你能发布一些代码吗？在updateUserStatus
方法的某个地方，你调用了setFile:
或者是在错误类型的对象（UIImageView
）上，或者是使用指向已释放并替换为UIImageView
的对象的指针，在Objective-C异常的断点导航器中设置断点。这将导致应用程序停止在比main（）例程更有趣的地方。@NicolaMiotto我为ProfileViewController添加了代码。谢谢您的回答。@Annette:我不知道教程，但您正在某个地方用键profilePicture
将一个对象放入用户
词典中。字典里有什么东西？如果是UIImage
，则我的代码是正确的。如果它不是UIImage
，那么您需要找出字典中的内容，并将其转换为UIImageView
可以显示的内容。谢谢。这门课不正确。我需要将其更改为PFImageView。投票赞成
