`FBSDKLoginButton` works with `[FBSDKAccessToken currentAccessToken]` to

determine what to display, and automatically starts authentication when tapped (i.e.,
|
you do not need to manually subscribe action targets).
|
|
Like `FBSDKLoginManager`, you should make sure your app delegate is connected to
|
`FBSDKApplicationDelegate` in order for the button's delegate to receive messages.
|
|
`FBSDKLoginButton` has a fixed height of @c 30 pixels, but you may change the width. `initWithFrame:CGRectZero`
|
will size the button to its minimum frame.
