登录后FBProfilePictureView不显示个人资料图片

Question

I am using Facebook IOS SDK to display profile pictures of a few friends. When the app is not signed-in, FBProfilePictureView can display different pictures by assigning profileIDs. However, it displays nothing when the app is associated with a signed-in user. Why?

Thank you!

I had the same problem. If your app is designed like mine, you are likely setting the profileID in a callback that is executed once the FB user is logged in. The problem is the view controller doesn't know to update the FBProfilePictureView. The solution I found was to just update the model user object in the callback by assigning the profileID to one of its properties. You can then use that property to update the FBProfilePictureView's profileID property in the view controller's viewWillAppear property.
