Inherits from FBSDKButton : UIButton
Declared in FBSDKLoginButton.h

Overview

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.
