Japanese keyboard's height - iphone

I want to scroll up my form to let the keyboard under the UITextField. It works for English keyboard, but when i change to Japanese keyboard, my form only scroll up little. I debug and find out that the height of keyboard for two cases is difference.
I do as following
- (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
{
NSDictionary* info = [aNotification userInfo];
CGSize kbSize = [[info objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;
NSLog(#"kbSize.height=%0.1f", kbSize.height);
UIEdgeInsets contentInsets = UIEdgeInsetsMake(0.0, 0.0, kbSize.height, 0.0);
scrollView.contentInset = contentInsets;
scrollView.scrollIndicatorInsets = contentInsets;
CGRect aRect = self.view.frame;
aRect.size.height -= kbSize.height;
if (!CGRectContainsPoint(aRect, activeField.frame.origin) )
{
CGPoint scrollPoint = CGPointMake(0.0, activeField.frame.origin.y-kbSize.height);
[scrollView setContentOffset:scrollPoint animated:YES];
}
}
- (void)keyboardWillBeHidden:(NSNotification*)aNotification
{
UIEdgeInsets contentInsets = UIEdgeInsetsZero;
scrollView.contentInset = contentInsets;
scrollView.scrollIndicatorInsets = contentInsets;
}
- (void)textFieldDidBeginEditing:(UITextField *)textField
{
activeField = textField;
}
- (void)textFieldDidEndEditing:(UITextField *)textField
{
activeField = nil;
}
And here is the result of info:
For ENGLISH keyboard: kbSize.height=216.0
For JAPANESE keyboard: kbSize.height=252.0
Is there anyone got this case? And can somebody help me to solve this problem?
Thank you.

Why does the view scroll up when keyboard is present for a textview but not for a textfield?

I have a textfield and a textview in a scroll view. When I begin to edit the textview the view scrolls up appropriately so the keyboard does not hide the text. The textfield, however, does not scroll up but is hidden by the keyboard. I have set the delegates of the textfields and textviews to the view controllers. The code I have so far is below. Thanks for the help in advance.
- (void)textFieldDidBeginEditing:(UITextField *)textField
{
activeField = textField;
}
- (void)textFieldDidEndEditing:(UITextField *)textField
{
activeField = nil;
}

[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(keyboardWasShown:)

name:UIKeyboardWillHideNotification object:nil];
}
- (void)keyboardWasShown:(NSNotification*)aNotification
{
NSDictionary* info = [aNotification userInfo];
CGRect kbRect = [[info objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue];
kbRect = [self.view convertRect:kbRect toView:nil];
CGSize kbSize = kbRect.size;
UIEdgeInsets contentInsets = UIEdgeInsetsMake(0.0, 0.0, kbSize.height, 0.0);
pageScrollView.contentInset = contentInsets;
pageScrollView.scrollIndicatorInsets = contentInsets;
// 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, activeField.frame.origin) ) {
CGPoint scrollPoint = CGPointMake(0.0, activeField.frame.origin.y-kbSize.height);
[pageScrollView setContentOffset:scrollPoint animated:YES];
}
}
- (void)keyboardWillBeHidden:(NSNotification*)aNotification
{
UIEdgeInsets contentInsets = UIEdgeInsetsZero;
pageScrollView.contentInset = contentInsets;
pageScrollView.scrollIndicatorInsets = contentInsets;
}
michael tyson created TPKeyboardAvoiding which is very easy to use you can get it from github. https://github.com/michaeltyson/TPKeyboardAvoiding
I do not know why it works for your textview, but for a scrollview with textfields I am doing this manually via
// Called when the UIKeyboardDidShowNotification is sent.
- (void)keyboardWillBeShown:(NSNotification*)aNotification
{
if(keyboardShown) return;
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.5];
[UIView setAnimationDelegate:self];
NSDictionary* info = [aNotification userInfo];
// Get the size of the keyboard.
NSValue* keyboardFrameValue = [info objectForKey:UIKeyboardFrameEndUserInfoKey];
CGRect keyboardRectWrtScreen = [keyboardFrameValue CGRectValue];
CGRect keyboardRectWrtView = [scrollView convertRect:[[scrollView window] convertRect:keyboardRectWrtScreen fromWindow:nil] fromView: nil];
float keyboardHeight = keyboardRectWrtView.size.height;
scrollView.frame = CGRectMake(scrollView.frame.origin.x, scrollView.frame.origin.y, scrollView.frame.size.width,scrollView.frame.size.height-keyboardHeight);
if(activeTextField) {
CGRect rect = [contentView convertRect:[activeTextField bounds] fromView:activeTextField];
rect.origin.y -= 25;
rect.size.height += 50;
[scrollView scrollRectToVisible:rect animated:YES];
}
[UIView commitAnimations];
keyboardShown = YES;
}
as you see, I am manually moving the scroll view to the visible part, then ensuring that the text field is in the center of the scroll view.

Keyboard covering UITextView in Notes App

Hi guys I am making a notes app and I ran into a big problem. I am using a UITextView as the notepad. When the keyboard comes up it blocks some of the text in the UITextView. I have a input accessory view on the UITextView. I tried to find the answer in the internet and can not find a good answer.Any way to fix it? Here is a picture:
You might want to look at modifying the UITextView's contentOffset and contentInset. UITextField is a UIScrollView subclass after all.
I decided to subtract the UITextView height by the keyboard height:
NSDictionary* info = [notification userInfo];
kbSIZE = [[info objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue];
CGRect newTextViewFrame = self.notesTextView.frame;
newTextViewFrame.size.height -= kbSIZE.size.height;
newTextViewFrame.size.height += self.notesTextView.inputAccessoryView.frame.size.height;
self.notesTextView.frame = newTextViewFrame;
You have to set contentInset and scrollIndicatorInsets to the UIEdgeInsets of the keyboard height. The contentInset value makes the scrolling height taller, but allows you to still scroll content under the keyboard. The scrollIndicatorInsets makes the scroll indicators stop at the bottom of the keyboard.
- (void)viewDidLoad
{
[super viewDidLoad];
[[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
{
NSDictionary *info = [notification userInfo];
CGSize kbSize = [info[UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;
UIEdgeInsets contentInsets = UIEdgeInsetsMake(0.0, 0.0, kbSize.height, 0.0);
self.textView.contentInset = contentInsets;
self.textView.scrollIndicatorInsets = contentInsets;
}
- (void)keyboardWillHide:(NSNotification *)aNotification
{
self.textView.contentInset = UIEdgeInsetsZero;
self.textView.scrollIndicatorInsets = UIEdgeInsetsZero;
}

UITextField moving when keyboard will block it

I am trying to make it so that when you click the email field and the keyboard pops up it would move the view up. But right now with this code it moves the view up no matter what textfield I click. Also I cant get the keyboard to dismiss. Not sure how to set this code to only scroll to the active field?
code:
- (void)registerForKeyboardNotifications
{
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(keyboardWasShown:)
name:UIKeyboardDidShowNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(keyboardWillBeHidden:)
name:UIKeyboardWillHideNotification object:nil];
}
// 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);
scrollView.contentInset = contentInsets;
scrollView.scrollIndicatorInsets = contentInsets;
// 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.emailField.frame.origin) ) {
CGPoint scrollPoint = CGPointMake(0.0, self.emailField.frame.origin.y-kbSize.height);
[scrollView setContentOffset:scrollPoint animated:YES];
}
}
// Called when the UIKeyboardWillHideNotification is sent
- (void)keyboardWillBeHidden:(NSNotification*)aNotification
{
UIEdgeInsets contentInsets = UIEdgeInsetsZero;
scrollView.contentInset = contentInsets;
scrollView.scrollIndicatorInsets = contentInsets;
}
I have a view that looks like this (it is on a scrollview)
For this you can ignore the keyboard show/hide notifications and just use the UITextFieldDelegate protocol:
– (BOOL)textFieldShouldBeginEditing:(UITextField *)textField {
if([textField isEqual:self.emailTextField]){
// scroll up
}
return true;
}
– (BOOL)textFieldShouldEndEditing:(UITextField *)textField {
if([textField isEqual:self.emailTextField]){
// scroll back to start
}
return true;
}
– (BOOL)textFieldShouldBeginEditing:(UITextField *)textField {
if([textField isEqual:YourTextfieldName])
{
}
return true; // return true is needed.
}
– (BOOL)textFieldShouldEndEditing:(UITextField *)textField
{
if([textField isEqual:YourTextfieldName])
{
}
return true; //return true is needed.
}

Generic UITableView keyboard resizing algorithm

I've searched a lot for code that resizes the table view to accomodate for keyboard showing and hiding, but almost every single post i came across assumes that the table view is taking the entire view of its view controller. I have an iPad application where the table view is only taking part of the screen. What's the correct way to resize the table view in this case? (all the code in the posts i've mentioned above fails)
The following code does what you want and works with any device and any layout. The code is courtesy of the Sensible TableView framework (with permission to copy and use).
- (void)keyboardWillShow:(NSNotification *)aNotification
{
if(keyboardShown)
return;
keyboardShown = YES;
// Get the keyboard size
UIScrollView *tableView;
if([self.tableView.superview isKindOfClass:[UIScrollView class]])
tableView = (UIScrollView *)self.tableView.superview;
else
tableView = self.tableView;
NSDictionary *userInfo = [aNotification userInfo];
NSValue *aValue = [userInfo objectForKey:UIKeyboardFrameEndUserInfoKey];
CGRect keyboardRect = [tableView.superview convertRect:[aValue CGRectValue] fromView:nil];
// Get the keyboard's animation details
NSTimeInterval animationDuration;
[[userInfo objectForKey:UIKeyboardAnimationDurationUserInfoKey] getValue:&animationDuration];
UIViewAnimationCurve animationCurve;
[[userInfo objectForKey:UIKeyboardAnimationCurveUserInfoKey] getValue:&animationCurve];
// Determine how much overlap exists between tableView and the keyboard
CGRect tableFrame = tableView.frame;
CGFloat tableLowerYCoord = tableFrame.origin.y + tableFrame.size.height;
keyboardOverlap = tableLowerYCoord - keyboardRect.origin.y;
if(self.inputAccessoryView && keyboardOverlap>0)
{
CGFloat accessoryHeight = self.inputAccessoryView.frame.size.height;
keyboardOverlap -= accessoryHeight;
tableView.contentInset = UIEdgeInsetsMake(0, 0, accessoryHeight, 0);
tableView.scrollIndicatorInsets = UIEdgeInsetsMake(0, 0, accessoryHeight, 0);
}
if(keyboardOverlap < 0)
keyboardOverlap = 0;
if(keyboardOverlap != 0)
{
tableFrame.size.height -= keyboardOverlap;
NSTimeInterval delay = 0;
if(keyboardRect.size.height)
{
delay = (1 - keyboardOverlap/keyboardRect.size.height)*animationDuration;
animationDuration = animationDuration * keyboardOverlap/keyboardRect.size.height;
}
[UIView animateWithDuration:animationDuration delay:delay
options:UIViewAnimationOptionBeginFromCurrentState
animations:^{ tableView.frame = tableFrame; }
completion:^(BOOL finished){ [self tableAnimationEnded:nil finished:nil contextInfo:nil]; }];
}
}
- (void)keyboardWillHide:(NSNotification *)aNotification
{
if(!keyboardShown)
return;
keyboardShown = NO;
UIScrollView *tableView;
if([self.tableView.superview isKindOfClass:[UIScrollView class]])
tableView = (UIScrollView *)self.tableView.superview;
else
tableView = self.tableView;
if(self.inputAccessoryView)
{
tableView.contentInset = UIEdgeInsetsZero;
tableView.scrollIndicatorInsets = UIEdgeInsetsZero;
}
if(keyboardOverlap == 0)
return;
// Get the size & animation details of the keyboard
NSDictionary *userInfo = [aNotification userInfo];
NSValue *aValue = [userInfo objectForKey:UIKeyboardFrameEndUserInfoKey];
CGRect keyboardRect = [tableView.superview convertRect:[aValue CGRectValue] fromView:nil];
NSTimeInterval animationDuration;
[[userInfo objectForKey:UIKeyboardAnimationDurationUserInfoKey] getValue:&animationDuration];
UIViewAnimationCurve animationCurve;
[[userInfo objectForKey:UIKeyboardAnimationCurveUserInfoKey] getValue:&animationCurve];
CGRect tableFrame = tableView.frame;
tableFrame.size.height += keyboardOverlap;
if(keyboardRect.size.height)
animationDuration = animationDuration * keyboardOverlap/keyboardRect.size.height;
[UIView animateWithDuration:animationDuration delay:0
options:UIViewAnimationOptionBeginFromCurrentState
animations:^{ tableView.frame = tableFrame; }
completion:nil];
}
- (void) tableAnimationEnded:(NSString*)animationID finished:(NSNumber *)finished contextInfo:(void *)context
{
// Scroll to the active cell
if(self.activeCellIndexPath)
{
[self.tableView scrollToRowAtIndexPath:self.activeCellIndexPath atScrollPosition:UITableViewScrollPositionNone animated:YES];
[self.tableView selectRowAtIndexPath:self.activeCellIndexPath animated:NO scrollPosition:UITableViewScrollPositionNone];
}
}
Notes:
a. The above two methods have been added to the notification center using the following code:
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(keyboardWillHide:) name:UIKeyboardWillHideNotification object:nil];
b. The ivars used above has been declared like this:
BOOL keyboardShown;
CGFloat keyboardOverlap;
c. 'self.activeCellIndexPath' is always set to the indexPath of the cell owning the currently active UITextField/UITextView.
Enjoy! :)
I've found the easiest solution to be this one(I'm not fan of using subviews for this kind of stuff):
register for keyboard frame change notification(idealy register in viewWillAppear: and unregister in viewWillDisappear:):
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(keyboardDidChangeFrame:) name:UIKeyboardDidChangeFrameNotification object:nil];
and then in method:
- (void)keyboardDidChangeFrame:(NSNotification*)aNotification
{
NSDictionary* info = [aNotification userInfo];
UIWindow *window = [[[UIApplication sharedApplication] delegate] window];
CGRect kbFrame = [[info objectForKey:UIKeyboardFrameEndUserInfoKey] CGRectValue];
CGRect kbIntersectFrame = [window convertRect:CGRectIntersection(window.frame, kbFrame) toView:self.scrollView];
kbIntersectFrame = CGRectIntersection(self.bounds, kbIntersectFrame);
UIEdgeInsets contentInsets = UIEdgeInsetsMake(0.0, 0.0, kbIntersectFrame.size.height, 0.0);
self.scrollView.contentInset = contentInsets;
self.scrollView.scrollIndicatorInsets = contentInsets;
}
or if You want to get rid of the "jump" after changing contentInset:
- (void)keyboardDidChangeFrame:(NSNotification*)aNotification
{
NSDictionary* info = [aNotification userInfo];
UIWindow *window = [[[UIApplication sharedApplication] delegate] window];
CGRect kbFrame = [[info objectForKey:UIKeyboardFrameEndUserInfoKey] CGRectValue];
CGRect kbIntersectFrame = [window convertRect:CGRectIntersection(window.frame, kbFrame) toView:self.scrollView];
kbIntersectFrame = CGRectIntersection(self.scrollView.bounds, kbIntersectFrame);
// get point before contentInset change
CGPoint pointBefore = self.scrollView.contentOffset;
UIEdgeInsets contentInsets = UIEdgeInsetsMake(0.0, 0.0, kbIntersectFrame.size.height, 0.0);
self.scrollView.contentInset = contentInsets;
self.scrollView.scrollIndicatorInsets = contentInsets;
// get point after contentInset change
CGPoint pointAfter = self.scrollView.contentOffset;
// avoid jump by settings contentOffset
self.scrollView.contentOffset = pointBefore;
// and now animate smoothly
[self.scrollView setContentOffset:pointAfter animated:YES];
}
The simple solution is to add my extension UIViewController+Keyboard.swift to your project, with a single line setupKeyboardNotifcationListenerForScrollView(tableView) it will auto resize automatically. No need to subclass anything, just an extension! Its open source at SingleLineKeyboardResize
Simple solution - register to receive keyboard notifications on init or viewDidLoad with:
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(keyboardWillShow:)
name:UIKeyboardWillShowNotification
object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(keyboardWillHide:)
name:UIKeyboardWillHideNotification
object:nil];
then when the notification is received, you can use the given rect of the keyboard to adjust the frame of your tableView:
- (void)keyboardWillShow:(NSNotification *)notification
{
// Get the size of the keyboard.
CGSize keyboardSize = [[[notification userInfo] objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;
CGRect newTableFrame = _myTableView.frame;
//Here make adjustments to the tableview frame based on the value in keyboard size
...
_myTableView.frame = newTableFrame;
}
- (void)keyboardWillHide:(NSNotification *)notification
{
//Here change the table frame back to what it originally was.
}
Check out this project, it's drag and drop so just declare the tablview as type TPKeyboardAvoidingTableView
Here is the keyboard method:
func keyboardControl(notification: NSNotification, isShowing: Bool) {
var userInfo = notification.userInfo!
let keyboardRect = userInfo[UIKeyboardFrameEndUserInfoKey]!.CGRectValue
let curve = userInfo[UIKeyboardAnimationCurveUserInfoKey]!.unsignedIntValue
let convertedFrame = self.view.convertRect(keyboardRect, fromView: nil)
let heightOffset = self.view.bounds.size.height - convertedFrame.origin.y
let options = UIViewAnimationOptions(rawValue: UInt(curve) << 16)
let duration = userInfo[UIKeyboardAnimationDurationUserInfoKey]!.doubleValue
//your UITableView bottom constrant
self.tableViewMarginBottomConstraint.constant = heightOffset
var contentInsets = UIEdgeInsetsZero
if isShowing {
contentInsets = UIEdgeInsetsMake(0.0, 0.0, (keyboardRect.size.height), 0.0)
}
UIView.animateWithDuration(
duration,
delay: 0,
options: options.union(.LayoutSubviews).union(.BeginFromCurrentState),
animations: {
self.listTableView.contentInset = contentInsets
self.listTableView.scrollIndicatorInsets = contentInsets
self.listTableView.scrollBottomToLastRow()
self.view.layoutIfNeeded()
},
completion: { bool in
})
}
Here is the UITableView extension:
extension UITableView {
func totalRows() -> Int {
var i = 0
var rowCount = 0
while i < self.numberOfSections {
rowCount += self.numberOfRowsInSection(i)
i++
}
return rowCount
}
var lastIndexPath: NSIndexPath {
get { return NSIndexPath(forRow: self.totalRows()-1, inSection: 0) }
}
func scrollBottomToLastRow() {
self.scrollToRowAtIndexPath(self.lastIndexPath, atScrollPosition: .Bottom, animated: false)
}
}
You can achieve what you're looking for by using IQKeyboardManager, it's a codeless library, you just have to add it to your Podfile: pod 'IQKeyboardManager' and that's it, it will hand the scrolling effect when the keyboard is shown even if the UITextField/UITextView is not part of a scrollView/tableView.

What is the reason the UIKeyBoardWIllShowNotification called once?

I am using keyboardWasShown and keyboardWillBeHidden notification for sliding the view to get the visible text view.
I have a UITabBar application with six tabs.
In each view I am using the UINavigationController.
In the detail view of each UITableViewCell I am using the keyboard notifications.
So the problem is that the keyboard notifications work for the first time that I will use . on on the other tabs it won't work .
The code is as follows :
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(keyboardWasShown:)
name:UIKeyboardDidShowNotification
object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(keyboardWasHidden:)
name:UIKeyboardDidHideNotification
object:nil];
and the methods
- (void)keyboardWasShown:(NSNotification *)aNotification {
if ( keyboardShown )
return;
NSDictionary *info = [aNotification userInfo];
NSValue *aValue = [info objectForKey:UIKeyboardBoundsUserInfoKey];
CGSize keyboardSize = [aValue CGRectValue].size;
NSTimeInterval animationDuration = 0.300000011920929;
CGRect frame = self.view.frame;
frame.origin.y -= keyboardSize.height-100;
frame.size.height += keyboardSize.height-100;
[UIView beginAnimations:#"ResizeForKeyboard" context:nil];
[UIView setAnimationDuration:animationDuration];
self.view.frame = frame;
[UIView commitAnimations];
viewMoved = YES;
keyboardShown = YES;
}
- (void)keyboardWasHidden:(NSNotification *)aNotification {
if ( viewMoved && tvAddreview) {
NSDictionary *info = [aNotification userInfo];
NSValue *aValue = [info objectForKey:UIKeyboardBoundsUserInfoKey];
CGSize keyboardSize = [aValue CGRectValue].size;
NSTimeInterval animationDuration = 0.300000011920929;
CGRect frame = self.view.frame;
frame.origin.y += keyboardSize.height-100;
frame.size.height -= keyboardSize.height-100;
[UIView beginAnimations:#"ResizeForKeyboard" context:nil];
[UIView setAnimationDuration:animationDuration];
self.view.frame = frame;
[UIView commitAnimations];
viewMoved = NO;
}
keyboardShown = NO;
}
you should dothis in eachClass like this:
-(void) viewWillAppear: (BOOL)animated
{
[super viewWillAppear:animated];
NSNotificationCenter *nc = [NSNotificationCenter defaultCenter];
[nc addObserver:self
selector:#selector(keyboardWasShown:)
name:UIKeyboardWillShowNotification
object:nil];
[nc addObserver:self
selector:#selector(keyboardWasHidden:)
name:UIKeyboardWillHideNotification
object:nil];
}
- (void) viewWillDisappear: (BOOL)animated{
[super viewWillDisappear:animated];
NSNotificationCenter *nc = [NSNotificationCenter defaultCenter];
[nc removeObserver:self
name:UIKeyboardWillShowNotification
object:nil];
[nc removeObserver:self
name:UIKeyboardWillHideNotification
object:nil];
}
because the notifications are on the application level not to your class level. So if you have added them in one class and not in all classes, then going to the next class. the notification will still call the the key keyboardWasShown: and the other from the class in which you added the notifications hence your local variables like...
viewMoved = YES;
keyboardShown = YES;
will throw the bad excess exceptions
In your case it is also required to do in all 6 view controllers
Hope this helps.
