Question

How to move UITextView Up and Down when you start entering some value. Like in TextField we use its delegate method. What to do in case of UITextView ?

While editing complete View will move up and after done editing will move down...

- (void)textViewDidBeginEditing:(UITextView *)textView
{
   [self animateTextView: YES];
 }

- (void)textViewDidEndEditing:(UITextView *)textView
 {
   [self animateTextView:NO];
  }

- (void) animateTextView:(BOOL) up
    {
        const int movementDistance =heightKeyboard; // tweak as needed
        const float movementDuration = 0.3f; // tweak as needed
        int movement= movement = (up ? -movementDistance : movementDistance);
        NSLog(@"%d",movement);

        [UIView beginAnimations: @"anim" context: nil];
        [UIView setAnimationBeginsFromCurrentState: YES];
        [UIView setAnimationDuration: movementDuration];
        self.view.frame = CGRectOffset(self.inputView.frame, 0, movement);
        [UIView commitAnimations];
    }

I hope this will help you...

Hum, you should use block for animation, your method is discouraged since iOS4 – Beuj Oct 04 '13 at 13:59

I faced lot of issues with this code. solved it by replacing 'self.inputView.frame' with 'self.view.frame' . – Rajesh Jul 07 '14 at 12:40
When you cannot use solution with scrollview, this is the easiest and best way – Alex Sorokoletov Oct 28 '14 at 20:36

Here is a sample code that will handle the keyboard automatically for you. Keyboard avoiding

If you are using TableView then your tableView must be a subclass of TPKeyboardAvoidingTableView and if you are using scrollview then your scrollview must be a subclass of TPKeyboardAvoidingScrollView. And this library will automatically do keyboard handling for you.

I suggest you to take a look at this guide

in particular at section: Moving Content That Is Located Under the Keyboard. I have used this approach successfully several times.

I did by changing the frame.

-(void)textViewDidBeginEditing:(UITextView *)textView{

[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.5];
[UIView setAnimationTransition:UIViewAnimationTransitionNone forView:viewMsg cache:YES];
viewMsg.frame = CGRectMake(10, 50, 300, 200);
[UIView commitAnimations];

NSLog(@"Started editing target!");

}

-(void)textViewDidEndEditing:(UITextView *)textView
{
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.5];
[UIView setAnimationTransition:UIViewAnimationTransitionNone forView:viewMsg cache:YES];
viewMsg.frame = CGRectMake(10, 150, 300, 200);
[UIView commitAnimations];
}

#define kOFFSET_FOR_KEYBOARD 80.0

-(void)keyboardWillShow {
    // Animate the current view out of the way
    if (self.view.frame.origin.y >= 0)

    [UIView commitAnimations];

Annnnnddd you should use block for animation, your method is discouraged since iOS4... — Beuj, Oct 04 '13 at 13:59
...and you shouldn't use a constant for the keyboard size, you're encouraged to get the offset size from Apple. — Matt Parkins, Sep 22 '14 at 15:33
