hello,

For making keyboard Done button press :-

import keyboard displacement by adding this line

#define kOFFSET_FOR_KEYBOARD  80.0

here you can set 80.0 according to your need

-(void)textFieldDidBeginEditing:(UITextField *)sender
{

    if ([sender isEqual:TextField])
    {

        if  (self.view.frame.origin.y >= 0)
        {
            [self setViewMovedUp:YES];
        }
    }
}

-(void)setViewMovedUp:(BOOL)movedUp
{
    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:0.5];  
    CGRect rect = self.view.frame;
    if (movedUp)
    {
                rect.origin.y -= kOFFSET_FOR_KEYBOARD;
        rect.size.height += kOFFSET_FOR_KEYBOARD;
    }
    else
    {
        // revert back to the normal state.
        rect.origin.y += kOFFSET_FOR_KEYBOARD;
        rect.size.height -= kOFFSET_FOR_KEYBOARD;
    }
    self.view.frame = rect;

    [UIView commitAnimations];
}


- (void)keyboardWillShow:(NSNotification *)notif
{


    if ([TextField isFirstResponder] && self.view.frame.origin.y >= 0)
    {
        flag=YES;

        [self setViewMovedUp:YES];
    }
    else if (![TextField isFirstResponder] && self.view.frame.origin.y < 0)
    {
        [self setViewMovedUp:NO];
    }
}




- (void)viewWillAppear:(BOOL)animated
{
    // register for keyboard notifications
    [[NSNotificationCenter defaultCenter]addObserver:self selector:@selector

(keyboardWillShow:)

                 name:UIKeyboardWillShowNotification object:self.view.window]; 
}

- (void)viewWillDisappear:(BOOL)animated
{
    // unregister for keyboard notifications while not visible.
    [[NSNotificationCenter defaultCenter]

removeObserver:self name:UIKeyboardWillShowNotification object:nil]; }

-(void) touchesBegan :(NSSet *) touches withEvent:(UIEvent *)event
{

    //NSLog(@"%@",flag);
    if (flag==TRUE)
    {
    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:0.5];
    CGRect rect = self.view.frame;
    rect.origin.y += kOFFSET_FOR_KEYBOARD;
    rect.size.height -= kOFFSET_FOR_KEYBOARD;
    self.view.frame = rect;

    [UIView commitAnimations];
        flag=FALSE;
    }
    [TextField resignFirstResponder];
        [super touchesBegan:touches withEvent:event ];
}
