Keyboard hiding textfield animation for another View - iphone

Question

When I press my textfield, the keyboard hides it. So I have implemented this code to "scroll" the view up:
- (void)textFieldDidBeginEditing:(UITextField *)textField
{
[self animateTextField: textField up: YES];
}
- (void)textFieldDidEndEditing:(UITextField *)textField
{
[self animateTextField: textField up: NO];
}
- (void) animateTextField: (UITextField*) textField up: (BOOL) up
{
const int movementDistance = 80; // tweak as needed
const float movementDuration = 0.3f; // tweak as needed
int movement = (up ? -movementDistance : movementDistance);
[UIView beginAnimations: #"anim" context: nil];
[UIView setAnimationBeginsFromCurrentState: YES];
[UIView setAnimationDuration: movementDuration];
self.view.frame = CGRectOffset(self.view.frame, 0, movement);
[UIView commitAnimations];
}
The UIView I'm trying to do this on is in another nib. I think since I have two UIViews, the program is getting confused and doesn't know which one to set the animation to.
I don't get any errors, but the animation isn't happening.
I've declared the UIView "surveyPage" for the view I'm trying to animate. Is there somewhere in the code above where I have to specify the UIView I want to animate?
Update:
The suggestion below didn't work for me. I tried changing self.view to surveyPage.
Above the code I posted above, I have this in my program:
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
[self.view endEditing:YES];
}
The above code works without a problem, yet the animation does not.

You're specifying the UIView here:
self.view.frame = CGRectOffset(self.view.frame, 0, movement);
it's self.view.
Try:
[UIView animateWithDuration:movementDuration animations:^{
self.view.frame = CGRectOffset(self.view.frame, 0, movement);
}];
instead of
[UIView beginAnimations: #"anim" context: nil];
[UIView setAnimationBeginsFromCurrentState: YES];
[UIView setAnimationDuration: movementDuration];
self.view.frame = CGRectOffset(self.view.frame, 0, movement);
[UIView commitAnimations];
