The file ' s owner in iOS

Seen from the StackOverflow.

Two points to being remembered:the File owner is the "object" loads the nib. Ie. This object which receives the message Loadnibnamed:or initwithnibname:.                                  So if you are want to access the "objects in the nib" to "Loading it, you set a outlet to the" file owner My own understanding is this, if you have a custom control as CustomView, and then loadnibname to load the Xib file, then file ' s owner is best not to use, because Custo Mview can specifically deal with this xib need for the corresponding Iboutlet and ibaction, if you do not have such a customview, then you can set the file ' owner to a VC or custom class for processing and loading xib files, Note that this file ' owner must be consistent with the owner in the Loadnibname method, regardless of the circumstances.
