FBSDKLoginButton

เวอร์ชั่นที่ใหม่กว่าของคลาสนี้พร้อมแล้ว ตรวจสอบได้ เวอร์ชั่นล่าสุด

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, but you may change the width. initWithFrame:CGRectZero will size the button to its minimum frame.

publishPermissions

The publish permissions to request.

@property (copy,
    nonatomic) NSArray *publishPermissions;

Discussion:

Use defaultAudience to specify the default audience to publish to. Note this is converted to NSSet and is only an NSArray for the convenience of literal syntax.

readPermissions

The read permissions to request.

@property (copy,
    nonatomic) NSArray *readPermissions;

Typedefs

NS_ENUM

Indicates the desired login tooltip behavior.

typedef NS_ENUM(NSUInteger, FBSDKLoginButtonTooltipBehavior) { 
    FBSDKLoginButtonTooltipBehaviorAutomatic = 0, 
    FBSDKLoginButtonTooltipBehaviorForceDisplay = 1, 
    FBSDKLoginButtonTooltipBehaviorDisable = 2 
};

ค่าคงตัว	คำอธิบาย
`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.
