If you need to show a tooltip for login, consider using the FBSDKLoginTooltipView view.

声明语言: FBSDKTooltipView.h
presentFromView:

Show tooltip at the top or at the bottom of given view. Tooltip will be added to anchorView.window.rootViewController.view

参数描述
anchorView

View to show at, must be already added to window view hierarchy, in order to decide where tooltip will be shown. (If there's not enough space at the top of the anchorView in window bounds - tooltip will be shown at the bottom of it)

- (void) presentFromView:(UIView *)anchorView;
Discussion:

Use this method to present the tooltip with automatic positioning or use -presentInView:withArrowPosition:direction: for manual positioning If anchorView is nil or has no window - this method does nothing.

声明语言: FBSDKTooltipView.h
presentInView:withArrowPosition:direction:

Adds tooltip to given view, with given position and arrow direction.

参数描述
view

View to be used as superview.

arrowPosition

Point in view's cordinates, where arrow will be pointing

arrowDirection

Whenever arrow should be pointing up (message bubble is below the arrow) or down (message bubble is above the arrow).

- (void)
presentInView: (UIView *)view
withArrowPosition: (CGPoint)arrowPosition
direction: (FBSDKTooltipViewArrowDirection)arrowDirection;
