avoid view when opening keyboard from a UITextView inside a UITableView with custom cell

Question

I have a UIViewController that contains a UITableView with custom cells, inside the cell are UILabels, a couple of uneditable UI

Answer 1

When your table view contains data entry fields like a UITextField or a UITextView and the table view is long enough to cover the screen, you will have a problem accessing data entry fields that are hidden by the keyboard.
To overcome this problem two solutions are:

1. The easiest and recommended way is to use a UITableViewController instead of UIViewController, which automatic make sure keypad won't hide the editable field (If possible use this approach to avoid U.I. adjustment inconvenience)

2. If you use a UIViewController and a UITableView as its subview. You can scroll your UI’s frame by observing the UIKeyboardWillShowNotification and UIKeyboardWillHideNotification

   - (void)registerForKeyboardNotifications 
   {
           [[NSNotificationCenter defaultCenter] addObserver:self
                                                    selector:@selector(keyboardWillShow:)
                                                        name:UIKeyboardWillShowNotification object:nil]; //Posted immediately prior to the display of the keyboard
   
           [[NSNotificationCenter defaultCenter] addObserver:self
                                                    selector:@selector(keyboardWillHide:)
                                                        name:UIKeyboardWillHideNotification object:nil]; //Posted immediately prior to the dismissal of the keyboard.
   }
   
   
   - (void)keyboardWillShow:(NSNotification *)aNotification 
   {  
       CGRect keyboardBounds = [[[aNotification userInfo] objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue];
   
       [UIView beginAnimations:nil context:nil];
       [UIView setAnimationBeginsFromCurrentState:YES];
   
       self.tableView.contentInset = UIEdgeInsetsMake(0, 0, keyboardBounds.size.height, 0); //when keyboard is up, that time just bring your text filed above the keyboard
       self.tableView.scrollIndicatorInsets = UIEdgeInsetsMake(0, 0, keyboardBounds.size.height, 0);
   
       [self.tableView scrollToRowAtIndexPath:[self findIndexPathToScroll]
                             atScrollPosition:UITableViewScrollPositionTop
                                     animated:YES]; //findIndexPathToScroll implementation not shown
       [UIView commitAnimations];
   }
   
   - (void)keyboardWillHide:(NSNotification *)aNotification 
   {
       [UIView beginAnimations:nil context:nil];
       [UIView setAnimationBeginsFromCurrentState:YES];
       self.tableView.contentInset = UIEdgeInsetsZero; //Once keyboard is hidden then bring back your table into your original position.
       self.tableView.scrollIndicatorInsets = UIEdgeInsetsZero;
       [UIView commitAnimations];
   }
   

   • registerForKeyboardNotifications - call this method when you load the UITableView, ie: viewDidLoad

   • findIndexPathToScroll - (Implementation not shown) Its your business logic to prepare IndexPath where table view should scroll

   • removeObserver 'UIKeyboardWillShowNotification' and 'UIKeyboardWillHideNotification' both in dealloc and viewDidUnload
