@abstract Represents a tooltip to be displayed next to a Facebook login button
|
to highlight features for new users.
|
|
@discussion The `FBSDKLoginButton` may display this view automatically. If you do
|
not use the `FBSDKLoginButton`, you can manually call one of the `present*` methods
|
as appropriate and customize behavior via `FBSDKLoginTooltipViewDelegate` delegate.
|
|
By default, the `FBSDKLoginTooltipView` is not added to the superview until it is
|
determined the app has migrated to the new login experience. You can override this
|
(e.g., to test the UI layout) by implementing the delegate or setting `forceDisplay` to YES.
