NS_ENUM
Acts with the most appropriate mode that is available.
typedef NS_ENUM(NSUInteger, FBSDKShareDialogMode) { /*! */ FBSDKShareDialogModeAutomatic = 0, /*! */ FBSDKShareDialogModeNative, /*! */ FBSDKShareDialogModeShareSheet, /*! */ FBSDKShareDialogModeBrowser, /*! */ FBSDKShareDialogModeWeb, /*! */ FBSDKShareDialogModeFeedBrowser, /*! */ FBSDKShareDialogModeFeedWeb, };
The automatic mode will progressively check the availability of different modes and open the most appropriate mode for the dialog that is available.
