UISearchController doesn't move my UITableView up

Question

As you can see, my UITableView 's scroll is maximum down, but my table is not fully visible. Why? I use UITableViewController

Answer 1

Good alternative to Ortwin's answer is to use keyboardDismissMode property of UIScrollView :

tableView.keyboardDismissMode = .OnDrag

Swift 4.1

tableView.keyboardDismissMode = .onDrag

Answer 2

I recommend to simply hide the keyboard as soon as the user starts scrolling. Apple implements this behavior in their own apps. To do that, add in your table view controller:

- (void)scrollViewWillBeginDragging:(UIScrollView *)scrollView {
    [self.searchBar resignFirstResponder];
}

This requires a searchBar property that is populated with the search bar.

Answer 3

using notifications might be easiest way to get the keyboard height as i commented set contentInset property to scroll the tableview above the keyboard, once it hides set to zero insects,

- (void)viewWillAppear:(BOOL)animate
{
  [super viewWillAppear:animate];
  // Do any additional setup after loading the view.
  [[NSNotificationCenter defaultCenter] addObserver:self
                                           selector:@selector(keyboardShown:) 
                                               name:UIKeyboardWillShowNotification object:nil];
  [[NSNotificationCenter defaultCenter] addObserver:self
                                           selector:@selector(keyboardHidden:)
                                               name:UIKeyboardWillHideNotification object:nil];
}

- (void)viewWillDisappear:(BOOL)animated
{
  //remove notifications
}


- (void)keyboardShown:(NSNotification*)aNotification
{
  NSDictionary* info = [aNotification userInfo];
  CGRect keyboardRect = [[info objectForKey:UIKeyboardFrameEndUserInfoKey] CGRectValue];

  float height = keyboardRect.size.height;
  tableView.contentInset = UIEdgeInsetsMake(10, 0, height, 0); 
}

- (void)keyboardHidden:(NSNotification*)aNotification
{
  [UIView animateWithDuration:0.2 animations:^{
    table.contentInset = UIEdgeInsetsMake(0, 0, 0, 0);
  }];
}
