Hi I'm getting the error:
Property 'editingIndexPath' not found on object of type 'ViewController *' with the line:
[self.tableView scrollToRowAtIndexPath:self.editingIndexPath atScrollPosition:UITableViewScrollPositionTop animated:YES];
The error has something to do with this call: self.editingIndexPath
How would I fix this error?
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(keyboardWillShow:)
name:UIKeyboardWillShowNotification
object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(keyboardWillHide:)
name:UIKeyboardWillHideNotification
object:nil];
}
- (void)keyboardWillShow:(NSNotification *)notification
{
CGSize keyboardSize = [[[notification userInfo] objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;
UIEdgeInsets contentInsets;
if (UIInterfaceOrientationIsPortrait([[UIApplication sharedApplication] statusBarOrientation])) {
contentInsets = UIEdgeInsetsMake(0.0, 0.0, (keyboardSize.height), 0.0);
} else {
contentInsets = UIEdgeInsetsMake(0.0, 0.0, (keyboardSize.width), 0.0);
}
self.tableView.contentInset = contentInsets;
self.tableView.scrollIndicatorInsets = contentInsets;
[self.tableView scrollToRowAtIndexPath:self.editingIndexPath atScrollPosition:UITableViewScrollPositionTop animated:YES];
}
- (void)keyboardWillHide:(NSNotification *)notification
{
self.tableView.contentInset = UIEdgeInsetsZero;
self.tableView.scrollIndicatorInsets = UIEdgeInsetsZero;
}
Compiler tells you everything. Just define a editingIndexPath property.
#property(nonatomic, strong) NSIndexPath *editingIndexPath

I have 10 textfields on tableview that tableview scrolling disabled.
How to handle keyboard avoiding textfields.
The Following is what I have tried with
// Register notification when the keyboard will be show
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(keyboardWasShown:)
name:UIKeyboardWillShowNotification
object:nil];
// Register notification when the keyboard will be hide
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(keyboardWillBeHidden:)
name:UIKeyboardWillHideNotification
object:nil];
pragma mark - keyboard notification (Called when the UIKeyboardDidShowNotification is sent.)
- (void)keyboardWasShown:(NSNotification*)aNotification
{
NSDictionary* info = [aNotification userInfo];
CGSize kbSize = [[info objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;
UIEdgeInsets contentInsets = UIEdgeInsetsMake(0.0, 0.0, kbSize.height, 0.0);
guestRechargeTableView.contentInset = contentInsets;
guestRechargeTableView.scrollIndicatorInsets = contentInsets;
// If active text field is hidden by keyboard, scroll it so it's visible
// Your app might not need or want this behavior.
CGRect aRect = self.view.frame;
aRect.size.height -= kbSize.height;
if (!CGRectContainsPoint(aRect, activeField.frame.origin) )
{
[guestRechargeTableView scrollRectToVisible:activeField.frame animated:YES];
}
}
// Called when the UIKeyboardWillHideNotification is sent
- (void)keyboardWillBeHidden:(NSNotification*)aNotification
{
UIEdgeInsets contentInsets = UIEdgeInsetsZero;
guestRechargeTableView.contentInset = contentInsets;
guestRechargeTableView.scrollIndicatorInsets = contentInsets;
}
This is working but not proper when selecting on textfield and moves up.Provide solution for that or any other alternative answer..
Happy Coding....
I've add a scrollView in the view controller and register keyboard show and hidden notifications
- (void)viewDidLoad {
[super viewDidLoad];
self.navigationController.navigationBar.translucent = NO;
[self registerForKeyboardNotifications];
// add UITapGestureRecognizer
UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc]
initWithTarget:self
action:#selector(dismissKeyboard)];
[scrollView addGestureRecognizer:tap];
scrollView.delegate = self;
[self setupAView];
}
- (void)setupAView {
// setting up aView...
scrollView.contentSize = CGSizeMake(self.view.frame.size.width, aView.frame.size.height);
-(void)dismissKeyboard {
[aView.aTextView resignFirstResponder];
}
- (void)registerForKeyboardNotifications
{
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(keyboardWasShown:)
name:UIKeyboardDidShowNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(keyboardWillBeHidden:)
name:UIKeyboardWillHideNotification object:nil];
}
- (void)keyboardWasShown:(NSNotification*)aNotification
{
UIEdgeInsets contentInsets = UIEdgeInsetsMake(0.0, 0.0, aView.frame.size.height, 0.0);
scrollView.contentInset = contentInsets;
scrollView.scrollIndicatorInsets = contentInsets;
CGPoint aPoint = CGPointMake(0, aView.frame.size.height);
[scrollView setContentOffset:aPoint animated:NO];
}
- (void)keyboardWillBeHidden:(NSNotification*)aNotification
{
// scrollView insets
UIEdgeInsets contentInsets = UIEdgeInsetsZero;
scrollView.contentInset = contentInsets;
scrollView.scrollIndicatorInsets = contentInsets;
}
this works fine, when I tap aTextView and aView in scrollView will move above keyboard view, but meanwhile if I scrolled the scrollView, whole view will automatically drop down a bit, How come the action will change the insets value or the scrollView contentSize value?
I have a UITextField embedded in a UIScrollView, and I want the text field to scroll up to be visible when the keyboard is active. I tried the top answer in How to make a UITextField move up when keyboard is present? but it seems that it does not work with auto-layout, so instead I took the code from the apple docs. This almost works, but its not scrolling the view until the user actually enters some data, rather than when the keyboard actually appears.
Here's what I'm doing - is there something obviously wrong?
// Call this method somewhere in your view controller setup code.

// If active text field is hidden by keyboard, scroll it so it's visible
// Your application might not need or want this behavior.
CGRect aRect = self.view.frame;
aRect.size.height -= kbSize.height;
if (!CGRectContainsPoint(aRect, self.activeField.frame.origin) ) {
[self.scrollView scrollRectToVisible:self.activeField.frame animated:YES];
}
}

Try this,

bool keyboardIsShown;
UITapGestureRecognizer *tapGesture;
ViewController.m
- (void)viewDidLoad
{
[super viewDidLoad];
tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(dismissKeyboard)];
tapGesture.cancelsTouchesInView = NO;
[self.view addGestureRecognizer:tapGesture];
scrollView.contentSize =CGSizeMake(0, self.view.frame.size.height+50);
// register for keyboard notifications
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(keyboardWillShow:)
name:UIKeyboardWillShowNotification
object:self.view.window];
// register for keyboard notifications
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(keyboardWillHide:)
name:UIKeyboardWillHideNotification
object:self.view.window];
keyboardIsShown = NO;
}
- (void)viewDidUnload
{
[super viewDidUnload];
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
// unregister for keyboard notifications while not visible.
[[NSNotificationCenter defaultCenter] removeObserver:self
name:UIKeyboardWillShowNotification
object:nil];
// unregister for keyboard notifications while not visible.
[[NSNotificationCenter defaultCenter] removeObserver:self
name:UIKeyboardWillHideNotification
object:nil];
}
///// KEYBOARD
- (void) moveView:(float) yPos
{
[scrollView setContentOffset:CGPointMake(0, yPos) animated:YES];
}
- (void)keyboardWillHide:(NSNotification *)n
{
keyboardIsShown = NO;
[self.view removeGestureRecognizer:tapGesture];
[self moveView:0.0];
}
- (void)keyboardWillShow:(NSNotification *)n
{
if (keyboardIsShown)
{
return;
}
keyboardIsShown = YES;
[self.view addGestureRecognizer:tapGesture];
[self moveView:255.0];
}
// method to hide keyboard when user taps on a scrollview
-(void)dismissKeyboard
{
[self.view endEditing:YES];
}
Try the code below:
-(void)keyboardWillShow:(id)sender
{
if ([orientation==#"Landscape"])
[loginScrollView setContentSize:CGSizeMake(480, 620)];
else
[loginScrollView setContentSize:CGSizeMake(320, 670)];
}
and while editing the text use this
- (void)textFieldDidBeginEditing:(UITextField *)textField {
if ([orientation == #"Landscape"]) {
if (textField == usernameTextField)
[loginScrollView setContentOffset:CGPointMake(xValue, 200) animated:YES];
if (textField == passwordTextField)
[loginScrollView setContentOffset:CGPointMake(xValue, 220) animated:YES];
}
else{
if (textField == usernameTextField)
[loginScrollView setContentOffset:CGPointMake(xValue, 168) animated:YES];
if (textField == passwordTextField)
[loginScrollView setContentOffset:CGPointMake(xValue, 172) animated:YES];
}
}
This probably isn't an easy one to answer....
I have 8 text fields on screen which sit in a scrollView. When I select the first field, the keyboard appears and the scrollView shrinks. I can then scroll up and down.
When I select another text field, I can't scroll anymore.
I've checked the scrollView height using textFieldDidBeginEditing and it definitely grows back up.
I've also registered for all 4 of the keyboard notifications but none of them are triggered during the move to the new text field.
Any pointers would be much appreciated :)

[self.scrollView setContentOffset:scrollPoint animated:YES];
}

In this kind of tasks I'm using BSKeyboardControls
There is good example project and Usage description
I am using UITableView, where each cell contains a UITextField, and using Apple official example, I wish to perform goal, moving the active field above the keyboard if it's already hidden. However, the form doesn't move although the UITableView is scroll eabled. Here is my relevant code, please help me pointing on what seems to be missing/wrong:
#interface ViewController (){
UITextField *activeField;
}
