My table view automatically resize when keyboard appear

Question

I'm working on a chat app.When my keyboard appear I want to resize the table view and text view according to the keyboard frame.

The problem is that my table view automatically resize and reposition when my key board appear.

My code is..

-(void)KeyboardWillShow:(NSNotification *)keyboardInfo
{
    @try {
        NSDictionary *userInfo = keyboardInfo.userInfo;
        // Get keyboard size.
        NSValue *endFrameValue = userInfo[UIKeyboardFrameEndUserInfoKey];
        CGRect keyboardEndFrame = [self.view convertRect:endFrameValue.CGRectValue fromView:nil];

        // Get keyboard animation.

        NSNumber *durationValue = userInfo[UIKeyboardAnimationDurationUserInfoKey];
        NSTimeInterval animationDuration = durationValue.doubleValue;

        NSNumber *curveValue = userInfo[UIKeyboardAnimationCurveUserInfoKey];
        UIViewAnimationCurve animationCurve = curveValue.intValue;
[UIView animateWithDuration:animationDuration delay:0.0 options:(animationCurve<<16) animations:^{

    [self.messageView setFrame:CGRectMake(self.messageView.frame.origin.x, self.view.frame.size.height-keyboardEndFrame.size.height-self.messageView.frame.size.height, self.messageView.frame.size.width, self.messageView.frame.size.height)];

   [self.tableView setFrame:CGRectMake(self.tableView.frame.origin.x, self.tableView.frame.origin.y, self.tableView.frame.size.width, self.view.frame.size.height-keyboardEndFrame.size.height-self.messageView.frame.size.height-self.tableView.frame.origin.y)];
} completion:nil];
    }

    @catch (NSException *exception) {

   NSLog(@"Error in func:%s, line:%d with reason:%@",__func__,__LINE__,exception.reason);
    }

}

You are changing frame of tableview so what's the issue here?? — Ahmad Ishfaq, May 10 '16 at 13:40
You have given constraint to tableview the frame won't change than you have to change the bottom constraint of tableview — Ahmad Ishfaq, May 10 '16 at 13:44

Take an outlet of bottom constraint of tableview and programatically change it like this

tablebottomConstraint.constant =  keyboardEndFrame.size.height+self.messageView.frame.size.height

You cold use the table inset, modyfying the bottom inset of the content of tableView :

self.tableView.contentInset = UIEdgeInsetsMake(0, 0, keyboardEndFrame.size.height + self.messageView.frame.size.height, 0);
