FBLoginView is a custom UIView that renders a button to login or logout based on the state of FBSession.activeSession

Discussion:

This view is closely associated with FBSession.activeSession. Upon initialization, it will attempt to open an active session without UI if the current active session is not open.

The FBLoginView instance also monitors for changes to the active session.

Properties
defaultAudience

The default audience to use, if publish permissions are requested at login time.

@property (nonatomic, assign) FBSessionDefaultAudience defaultAudience;
Declared In: FBLoginView.h
delegate

The delegate object that receives updates for selection and display control.

@property (nonatomic, assign) IBOutlet id<FBLoginViewDelegate> delegate;
Declared In: FBLoginView.h
loginBehavior

The login behavior for the active session if the user logs in via this view

@property (nonatomic) FBSessionLoginBehavior loginBehavior;
Discussion:

The default value is FBSessionLoginBehaviorUseSystemAccountIfPresent.

permissions

The permissions to login with. Defaults to nil, meaning basic permissions.

@property (readwrite, copy) NSArray *permissions __attribute__((deprecated
Discussion:

Methods and properties that specify permissions without a read or publish qualification are deprecated; use of a read-qualified or publish-qualified alternative is preferred.

Declared In: FBLoginView.h
publishPermissions

The publish permissions to request if the user logs in via this view.

@property (nonatomic, copy) NSArray *publishPermissions;
Discussion:

Note, that a defaultAudience value of FBSessionDefaultAudienceOnlyMe, FBSessionDefaultAudienceEveryone, or FBSessionDefaultAudienceFriends should be set if publish permissions are specified. Additionally, when publish permissions are specified, then read should not be specified.

Declared In: FBLoginView.h
readPermissions

The read permissions to request if the user logs in via this view. The basic_info permission must be explicitly requested at first login, and is no longer inferred, (subject to an active migration.)

@property (nonatomic, copy) NSArray *readPermissions;
Discussion:

Note, that if read permissions are specified, then publish permissions should not be specified.

Declared In: FBLoginView.h
