iOS - Interface elements overlapping when move the view - ios

Question

I have the following interface layout on my application:
When I click on a text field (if you lick add tag a new text field is added) I make my view scroll up as to not be obstructed by the keyboard so the user can properly see what he's typing, but the following happens when I do so:
This is the code I use to scroll:
- (void)keyboardWillShow:(NSNotification *)notification {
if (self.keyboardIsShown) {
return;
}
NSValue *keyboardBoundsValue = [[notification userInfo] objectForKey:UIKeyboardFrameBeginUserInfoKey];
CGSize keyboardSize = [keyboardBoundsValue CGRectValue].size;
NSTimeInterval animationDuration = 0.3;
CGRect frame = self.view.frame;
frame.origin.y -= keyboardSize.height - 94 + self.firstResponder.superview.superview.frame.origin.y;
frame.size.height += keyboardSize.height - 94 + self.firstResponder.superview.superview.frame.origin.y;
[UIView beginAnimations:#"ResizeForKeyboard" context:nil];
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationDuration:animationDuration];
self.view.frame = frame;
[UIView commitAnimations];
self.keyboardIsShown = YES;
}
- (void)keyboardWillHide:(NSNotification *)notification {
NSValue *keyboardBoundsValue = [[notification userInfo] objectForKey:UIKeyboardFrameBeginUserInfoKey];
CGSize keyboardSize = [keyboardBoundsValue CGRectValue].size;
NSTimeInterval animationDuration = 0.3;
CGRect frame = self.view.frame;
frame.origin.y += keyboardSize.height - 94 + self.firstResponder.superview.superview.frame.origin.y;
frame.size.height -= keyboardSize.height - 94 + self.firstResponder.superview.superview.frame.origin.y;
[UIView beginAnimations:#"ResizeForKeyboard" context:nil];
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationDuration:animationDuration];
self.view.frame = frame;
[UIView commitAnimations];
self.keyboardIsShown = NO;
}
Any idea how I can make the view elements show behind the navbar or disappear or another workaround that would work properly?

Answer 1

A quick way to achieve what you want, would be to have your navigation bar below the "content"-view in your view tree. That way the navigation bar will remain on top. If you add the content dynamically. Make sure you add them as subviews of a view that is behind the navigation bar.
// Edit
As proposed in the comments:
self.view.clipsToBounds = YES;
CGRect frame = self.yourWrappingView.frame;
NSUInteger distanceToMove = 200;
self.yourWrappingView.frame = CGRectMake(frame.origin.x - distanceToMove, frame.origin.y, frame.size.width, frame.size.height);
This should work for you mate :)

Probably you are not using a real UINavigationController. But you should. So you wouldn't have those problems and a correct resizing behaviour. But to solve it in your current architecture:
Make sure the Navigation Bar is the top most object in your nib file / storyboard
add an IBOutlet for your UINavigationBar and if you insert new views dynamically, use [self insertSubview: newView belowSubview: navigationBarOutlet];
