Focus bar is animating faster than keyboard in iOS 7 - ios

Question

I am implementing a custom focus bar on top of my keyboard. The focus bar has widgets to move cursor back and forward along with a done button.
Now, with iOS 7, I am seeing the focus bar is moving faster than keyboard. Because of this for a second I see screen behind the focus bar before it sits on top of keyboard. This is working fine in iOS 6.
Below is what I am doing:
- (void)keyboardWillShow:(NSNotification *)iNotification {
self.dismissForm = NO;
self.shouldScrollCell = YES;
CGFloat aKeyboardAnimationDuration = [[iNotification userInfo][UIKeyboardAnimationDurationUserInfoKey] doubleValue];
CGRect aKeyboardFrame = [[iNotification userInfo][UIKeyboardFrameEndUserInfoKey] CGRectValue];
CGRect adjustedKeyboardFrame = [self.view convertRect:aKeyboardFrame fromView:nil];
CGFloat adjustedHeight;
adjustedHeight = aKeyboardFrame.size.height + self.focusControlBar.frame.size.height;
[self.focusControlBar viewForFocusControlWillShowWithEndFrame:adjustedKeyboardFrame andAnimationDuration:aKeyboardAnimationDuration];
[UIView animateWithDuration:0.3 animations:^() {
[self.tableView setContentInset:UIEdgeInsetsMake(kScreenOrigin, kScreenOrigin, adjustedHeight, 0.0f)];
[self.tableView setScrollIndicatorInsets:UIEdgeInsetsMake(kScreenOrigin, kScreenOrigin, adjustedHeight, 0.0f)];
}];
}
This is my focus bar animation code:
- (void)viewForFocusControlWillShowWithEndFrame:(CGRect)iFrame andAnimationDuration:(CGFloat)iDuration {
BOOL aShouldAppear = YES;
if (self.delegate && [self.delegate respondsToSelector:#selector(focusControlBarShouldAppear:)]) {
aShouldAppear = [self.delegate focusControlBarShouldAppear:self];
}
if (aShouldAppear) {
if (self.delegate && [self.delegate respondsToSelector:#selector(focusControlBarWillAppear:)]) {
[self.delegate focusControlBarWillAppear:self];
}
CGRect aBarFrame = self.frame;
UIInterfaceOrientation anInterfaceOrientation = [UIApplication sharedApplication].statusBarOrientation;
aBarFrame.size.height = [self heightForOrientation:anInterfaceOrientation];
self.frame = aBarFrame;
aBarFrame.origin.y = self.superview.bounds.size.height - iFrame.size.height - aBarFrame.size.height;
[UIView animateWithDuration:iDuration animations:^(void) {
self.frame = aBarFrame;
} completion:^(BOOL iFinished) {
if (self.delegate && [self.delegate respondsToSelector:#selector(focusControlBarDidAppear:)]) {
[self.delegate focusControlBarDidAppear:self];
}
}];
}
}

I just got to know that with iOS 7 we need to also keep KeyboardAnimationCurve into account. With the below modified code I had it worked.
- (void)keyboardWillShow:(NSNotification *)iNotification {
self.dismissForm = NO;
self.shouldScrollCell = YES;
NSDictionary *aNotificationInfo = [iNotification userInfo];
CGFloat aKeyboardAnimationDuration = [aNotificationInfo[UIKeyboardAnimationDurationUserInfoKey] doubleValue];
UIViewAnimationCurve aKeyboardAnimationCurve = [aNotificationInfo[UIKeyboardAnimationCurveUserInfoKey] intValue];
CGRect aKeyboardFrame = [aNotificationInfo[UIKeyboardFrameEndUserInfoKey] CGRectValue];
CGRect adjustedKeyboardFrame = [self.view convertRect:aKeyboardFrame fromView:nil];
CGFloat adjustedHeight;
adjustedHeight = aKeyboardFrame.size.height + self.focusControlBar.frame.size.height;
[self.focusControlBar viewForFocusControlWillShowWithEndFrame:adjustedKeyboardFrame animationCurve:aKeyboardAnimationCurve andAnimationDuration:aKeyboardAnimationDuration];
[UIView animateWithDuration:0.3 animations:^() {
[self.tableView setContentInset:UIEdgeInsetsMake(kScreenOrigin, kScreenOrigin, adjustedHeight, 0.0f)];
[self.tableView setScrollIndicatorInsets:UIEdgeInsetsMake(kScreenOrigin, kScreenOrigin, adjustedHeight, 0.0f)];
}];
}
- (void)viewForFocusControlWillShowWithEndFrame:(CGRect)iFrame animationCurve:(UIViewAnimationCurve)iAnimationCurve andAnimationDuration:(CGFloat)iDuration {
BOOL aShouldAppear = YES;
if (self.delegate && [self.delegate respondsToSelector:#selector(focusControlBarShouldAppear:)]) {
aShouldAppear = [self.delegate focusControlBarShouldAppear:self];
}
if (aShouldAppear) {
if (self.delegate && [self.delegate respondsToSelector:#selector(focusControlBarWillAppear:)]) {
[self.delegate focusControlBarWillAppear:self];
}
CGRect aBarFrame = self.frame;
UIInterfaceOrientation anInterfaceOrientation = [UIApplication sharedApplication].statusBarOrientation;
aBarFrame.size.height = [self heightForOrientation:anInterfaceOrientation];
self.frame = aBarFrame;
aBarFrame.origin.y = self.superview.bounds.size.height - iFrame.size.height - aBarFrame.size.height;
[UIView animateWithDuration:iDuration delay:0.0 options:(iAnimationCurve << 16) animations:^{
self.frame = aBarFrame;
} completion:^(BOOL finished) {
if (self.delegate && [self.delegate respondsToSelector:#selector(focusControlBarDidAppear:)]) {
[self.delegate focusControlBarDidAppear:self];
}
}];
}
}
