FBProfilePictureView object won't show image

Question

I'm doing the scrumptios facebook developer tutorial for the 3.1 iOS SDK. I've managed to display my profile name from facebook, however the FBProfilePictureView wont show the picture

here's the code for iboutlet

@property (strong, nonatomic) IBOutlet FBProfilePictureView *useProfileImage;

here is what I used to display the pic

self.useProfileImage.profileID = user.id;

I have confirmed that the it changed the profileid variable of the image by displaying it in a label.

When I first ran the project I had this error

"2012-05-18 04:04:11.620 Scrumptious[6548:f803] Unknown class FBProfilePictureView in Interface Builder file."

and solved it they way the FB tutorial suggested- by adding [FBProfilePictureView class]; to "applicationdidfinishlaunching: withoptions" in the app delegate.

any idea why the picture wouldn't show?

Answer 1

Adding the [FBProfilePictureView class]; as the first line in the app delegate method of didFinishLaunching seems kinda hacky to me.

Check out the HelloFacebookSample inside the SDK. Here is the 4 line comment:

// If you have not added the -ObjC linker flag, you may need to uncomment the following line because
// Nib files require the type to have been loaded before they can do the wireup successfully.
// http://stackoverflow.com/questions/1725881/unknown-class-myclass-in-interface-builder-file-error-at-runtime
// [FBProfilePictureView class];

I tried adding the -ObjC flag and it worked fine.

To resolve this, add this as the first line in the app delegate's application:didFinishLaunchingWithOptions: method:

[FBProfilePictureView class];
