This method causes the view or one of its UIView.Subviews to resign first responder status. If force is true, the field is not even asked to resign: it is forced.

This method returns true if the view or subview resigned first responder status. It will return false if:

• Neither the MonoTouch.UIKit.UIView nor any of its UIView.Subviews was first responder; or
• The force parameter was false and the first responder refused to resign (i.e., returned false from UIResponder.ResignFirstResponder.)
