UIView's initWithFrame is not firing.

Question

I have following files. UserSettingsViewController.h, UserSettingsViewController.m, UserSettingsViewController.xib, UserView.h, UserView.m.

Class of UserSettingsViewController.xib is set to UserSettingsViewController
There is a view in UserSettingsViewController.xib (you can see it in Interface builder's document window), i have set its class to UserView.

The problem is that initWithCoder of my UserView class is not firing. I have checked it both by setting break-points and by NSLog(@"initWithCoder") in that class. Why that method is not firing?
