Comment faire monter UITextView lorsque le clavier est présent

Comment se déplacer ITextView Haut et bas lorsque vous commencez à entrer une valeur. Comme dans TextField, nous utilisons sa méthode déléguée. Que faire en cas de ITextView?

Pendant la modification, la vue complète se déplacera vers le haut et après la modification, elle se déplacera vers le bas ...

- (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];
    }

J'espère que cela t'aidera...

Je vous suggère de jeter un œil à ce guide

en particulier dans la section: Déplacement de contenu situé sous le clavier . J'ai utilisé cette approche avec succès à plusieurs reprises.

Je l'ai fait en changeant le cadre.

-(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];
}
