Keyboard hides UITableView issue

Question

I have a view controller on which I have a table view, in the table view, each row has a text field, when I click on the keyboard of the text field and hide the table view and then do not see the editing, how can I fix this problem? I set an observer who corrected the alignment of the view controller, but it did not work here, this is the code.

- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField{ [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:nil]; return YES; } -(void)keyboardWillShow { // Animate the current view out of the way [UIView animateWithDuration:0.3f animations:^ { self.viewFrame = CGRectMake(0, -160, 320, 480); }]; }

 you have to write below code, it will hide and show keyboard. ====>.h file: declare one UITextField as below: UITextField *actifText; ====>.m file: -(void)viewDidAppear:(BOOL)animated { // Register notification when the keyboard will be show [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:nil]; // Register notification when the keyboard will be hide [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillHide:) name:UIKeyboardWillHideNotification object:nil]; } - (BOOL)textFieldShouldReturn:(UITextField *)textField { [textField resignFirstResponder]; return YES; } -(void)viewDidDisappear:(BOOL)animated { [[NSNotificationCenter defaultCenter] removeObserver:self]; } -(void) keyboardWillShow:(NSNotification *)note { // Get the keyboard size CGRect keyboardBounds; [[note.userInfo valueForKey:UIKeyboardFrameBeginUserInfoKey] getValue: &keyboardBounds]; // Detect orientation UIInterfaceOrientation orientation = [[UIApplication sharedApplication] statusBarOrientation]; CGRect frame = self.tblName.frame; // Start animation [UIView beginAnimations:nil context:NULL]; [UIView setAnimationBeginsFromCurrentState:YES]; [UIView setAnimationDuration:0.3f]; // Reduce size of the Table view if (orientation == UIInterfaceOrientationPortrait || orientation == UIInterfaceOrientationPortraitUpsideDown) frame.size.height -= keyboardBounds.size.height; else frame.size.height -= keyboardBounds.size.width; // Apply new size of table view self.tblName.frame = frame; // Scroll the table view to see the TextField just above the keyboard if (self.actifText) { CGRect textFieldRect = [self.tblName convertRect:self.actifText.bounds fromView:self.actifText]; [self.tblName scrollRectToVisible:textFieldRect animated:NO]; } [UIView commitAnimations]; } - (void)textFieldDidEndEditing:(UITextField *)textField { self.actifText = nil; } - (void)textFieldDidBeginEditing:(UITextField *)textField { self.actifText = textField; } -(void) keyboardWillHide:(NSNotification *)note { // Get the keyboard size CGRect keyboardBounds; [[note.userInfo valueForKey:UIKeyboardFrameBeginUserInfoKey] getValue: &keyboardBounds]; // Detect orientation UIInterfaceOrientation orientation = [[UIApplication sharedApplication] statusBarOrientation]; CGRect frame = self.tblName.frame; [UIView beginAnimations:nil context:NULL]; [UIView setAnimationBeginsFromCurrentState:YES]; [UIView setAnimationDuration:0.3f]; // Reduce size of the Table view if (orientation == UIInterfaceOrientationPortrait || orientation == UIInterfaceOrientationPortraitUpsideDown) frame.size.height += keyboardBounds.size.height; else frame.size.height += keyboardBounds.size.width; // Apply new size of table view self.tblName.frame = frame; [UIView commitAnimations]; }

When you click on a text field inside a cell, you need to know the current index path of the cell, so when the keyboard is displayed, you can focus it.

 -(BOOL) textFieldShouldBeginEditing:(UITextField *)textField { UITableViewCell *cell = (UITableViewCell *)[textField superview].superview; NSIndexPath *idxPath = [table indexPathForCell:cell]; selectedIndex = idxPath.row;//instance variable return YES; } -(void)keyboardWillShow { [table scrollToRowAtIndexPath:[NSIndexPath indexPathForRow:selectedIndex inSection:0] atScrollPosition:UITableViewScrollPositionTop animated:YES]; } 

Also add the following line to ViewDidLoad , meaning to watch when the keyboard appears. If you use UIKeyboardWillShowNotification , keyboardWillShow will be called first, followed by textFieldShouldBeginEditing: which is incorrect.

 [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:) name:UIKeyboardDidShowNotification object:nil]; 

and install

 textfield.delegate = self; 

in cellForRowAtIndexPath when creating a text field. It will call the required methods.
