你在哪里调用'setFile'？你可以发布一些代码吗？ – 2014-09-23 16:10:26

'updateUserStatus'方法中的某个地方，您在错误类型的对象（'UIImageView'）上调用'setFile：'，或者使用指向已释放的对象并用'UIImageView'代替的指针。 – 2014-09-23 16:11:42

另外，在断点导航器中设置Objective-C异常的断点。它会导致应用程序停止在比main（）例程更有趣的地方。 – 2014-09-23 16:13:05

在你ProfileViewController，在updateUserStatus方法，您呼叫的对象，不知道它的方法setFile。即：一个UIImageView。确保您正在使用您打算调用该方法的对象。

UPDATE：

我们去那里：

self.profileImageView.file = user[@"profilePicture"];

一个UIImageView，这样有profileImageView，没有一个file属性，所以你不能对它进行设置。仔细检查设置文件的目标类别。

谢谢。这个班是不正确的。我需要将其更改为PFImageView。投票 – Annette 2014-09-23 17:25:06
