ios 8 UITextField hides under Predictive View in iOS 8 - iphone

Question

I am developing a chat application in which I have UIView with UITableView and at the bottom of the UIView there is another UIView(say userInputView) with a UITextField and a UIButton added as a subview on it.
When the user taps on the UITextField keyboard appears and this UIView(userInputView) moves up to adjust itself as per keyboard height using UIKeyboardDidChangeFrameNotification.
When I tap the "Send" Button, I set the text of UITextField to nil.
This is working fine till iOS 7 but in iOS 8 when I change the text of the UITextField the userInputView view is hiding under predictive text view. When I minimize the predictive text view then userInputView is displayed again but when I maximize predictive textview it hides again.
All of this is happening when I try to change to change the text of UITextField on tapping the send button. If I don't change the text of UITextField then it works fine.
How can I resolve this issue in iOS8? Even if I hide predictive text view the userInputView will hide and never display again.

I have the same issue as yours but after checking the keyboard notifications enums.So,I used UIKeyboardDidChangeFrameNotification or UIKeyboardWillChangeFrameNotification because these will tell you the change in keyboard frame when predictive text bar gets up or down when keyboard is in view or user turn on or turn off from setting. Below is the code which working perfectly.
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(keyboardFrameDidChange:)
name:UIKeyboardDidChangeFrameNotification object:nil];
-(void)keyboardFrameDidChange:(NSNotification*)notification{
NSDictionary* info = [notification userInfo];
CGRect kKeyBoardFrame = [[info objectForKey:UIKeyboardFrameEndUserInfoKey] CGRectValue];
if (kKeyBoardFrame.size.height == HEIGHT_OF_KEYBOARD) {
[viewCommentText setFrame:CGRectMake(0, kKeyBoardFrame.size.height+32, 320, viewCommentText.frame.size.height)];
}else if (kKeyBoardFrame.size.height == 224){
[viewCommentText setFrame:CGRectMake(0, kKeyBoardFrame.size.height+18, 320, viewCommentText.frame.size.height)];
}else{
[viewCommentText setFrame:CGRectMake(0, kKeyBoardFrame.size.height-viewCommentText.frame.size.height, 320, viewCommentText.frame.size.height)];
}
}
and also remove observer when you are leaving your view
