presentFromView:

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

Thông số	Mô tả
`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.
