How to move up the UIView while writing in UITextField

Inside .h File of your ViewController

Declare UIText field delegate(

) in .h file

- (void)setViewMovedUp:(BOOL)movedUp;

Inside .m file of your ViewController

-(void)textFieldDidBeginEditing:(UITextField *)sender

{

NSLog(@"Inside textFieldDidBeginEditing");

    if ([sender isEqual:leftTextField] || [sender isEqual:rightTextField])

    {

NSLog(@"Inside textFieldDidBeginEditing (INSIDE IF)");

        //move the main view, so that the keyboard does not hide it.

        if  (self.view.frame.origin.y >= 0)

        {

NSLog(@"Inside textFieldDidBeginEditing (INSIDE y>0)");

            [self setViewMovedUp:YES];

        }

    }

}

- (void)keyboardWillShow:(NSNotification *)notif

{

    //keyboard will be shown now. depending for which textfield is active, move up or move down the view appropriately

    if (self.view.frame.origin.y >= 0)

    {

        [self setViewMovedUp:YES];

    }

    else if (self.view.frame.origin.y < 0)

    {

        [self setViewMovedUp:NO];

    }

}

//method to move the view up/down whenever the keyboard is shown/dismissed

-(void)setViewMovedUp:(BOOL)movedUp

{

//NSLog(@"Inside setViewMovedUp");

    [UIView beginAnimations:nil context:NULL];

    [UIView setAnimationDuration:0.5]; // if you want to slide up the view

    CGRect rect = self.view.frame;

    if (movedUp)

    {

NSLog(@"Inside else movedUP YES");

        // 1. move the view's origin up so that the text field that will be hidden come above the keyboard 

        // 2. increase the size of the view so that the area behind the keyboard is covered up.

        rect.origin.y -= kOFFSET_FOR_KEYBOARD;

        rect.size.height += kOFFSET_FOR_KEYBOARD;

    }

    else

    {

NSLog(@"Inside else movedUP NO");

        // revert back to the normal state.

        rect.origin.y += kOFFSET_FOR_KEYBOARD;

        rect.size.height -= kOFFSET_FOR_KEYBOARD;

    }

    self.view.frame = rect;

    [UIView commitAnimations];

}
