UISearchBar automatically resizes and changes frame

I have an issue with a search bar that behaves in a strange way when it becomes a `firstResponder` and when it resigns. The search bar is added as the header of a table view ``` self.searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0.0f, 0.0f, self.view.frame.size.width, 44.0f)]; self.searchBar.translucent = NO; self.searchBar.barTintColor = [UIColor grayColor]; self.tableView.tableHeaderView = self.searchBar; self.searchController = [[UISearchDisplayController alloc] initWithSearchBar:self.searchBar contentsController:self]; self.searchController.searchResultsDataSource = self; ``` The view controller is set a left panel of `JASidePanelController` and it hides the center panel when the keyboard shows or hides : ``` - (void)keyboardWillAppear:(NSNotification *)note { [self.sidePanelController setCenterPanelHidden:YES animated:YES duration:[[note.userInfo objectForKey:UIKeyboardAnimationDurationUserInfoKey] doubleValue]]; self.searchBar.showsCancelButton = YES; } - (void)keyboardWillDisappear:(NSNotification *)note { [self.sidePanelController setCenterPanelHidden:NO animated:YES duration:[[note.userInfo objectForKey:UIKeyboardAnimationDurationUserInfoKey] doubleValue]]; self.searchBar.showsCancelButton = NO; } ``` Normal state When the search bar becomes a `firstResponder` it either moves about a point up or point down randomly And When the search bar resigns it animates up to reach the window origin and then back to its natural frame Here is a sample project reproducing the bug. EDIT : As per @kwylez suggestion, the unwanted animation that the search bar makes when it resigns can be avoided by: ``` self.searchBar.clipsToBounds = YES; ```
