FBSDKLoginButton

A button that initiates a log in or log out flow upon tapping.

Discussion:

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.

Superclass:	`FBSDKButton`

Typedefs

NS_ENUM

Indicates the desired login tooltip behavior.

typedef NS_ENUM(NSUInteger, FBSDKLoginButtonTooltipBehavior) { 
    /*! The default behavior. The tooltip will only be displayed if
        */
    FBSDKLoginButtonTooltipBehaviorAutomatic = 0, /*! Force display of the tooltip (typically for UI testing) 
        */
    FBSDKLoginButtonTooltipBehaviorForceDisplay = 1, /*! Force disable. In this case you can still exert more refined
        */
    FBSDKLoginButtonTooltipBehaviorDisable = 2 
};

القيمة الثابتة	الوصف
`FBSDKLoginButtonTooltipBehaviorAutomatic`	The default behavior. The tooltip will only be displayed if the app is eligible (determined by possible server round trip)
`FBSDKLoginButtonTooltipBehaviorForceDisplay`	Force display of the tooltip (typically for UI testing)
`FBSDKLoginButtonTooltipBehaviorDisable`	Force disable. In this case you can still exert more refined control by manually constructing a `FBSDKLoginTooltipView` instance.
