Question

In my app, when I click on a text field, the keyboard hides it. Please help me — how can I move my view up when I click on the text field. I’m using this code in textFieldDidBeginEditing:

self.tableView.scrollIndicatorInsets = UIEdgeInsetsMake(0, 0, 216, 0);
self.tableView.contentInset = UIEdgeInsetsMake(0, 0, 216, 0);

but it doesn’t work.

You can do the following, but first make sure you’ve set the UITextField delegate to your self and

#define kOFFSET_FOR_KEYBOARD 350;

at the top. This is how far you want the view to be shifted

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

-(void)setViewMovedUp:(BOOL)movedUp
{
    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:0.3]; // if you want to slide up the view
    [UIView setAnimationBeginsFromCurrentState:YES];

    CGRect rect = self.view.frame;
    if (movedUp)
    {
        // 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.

        if (rect.origin.y == 0 ) {
            rect.origin.y -= kOFFSET_FOR_KEYBOARD;
            //rect.size.height += kOFFSET_FOR_KEYBOARD;
        }

    }
    else
    {
        if (stayup == NO) {
            rect.origin.y += kOFFSET_FOR_KEYBOARD;
            //rect.size.height -= kOFFSET_FOR_KEYBOARD;
        }
    }
    self.view.frame = rect; 
    [UIView commitAnimations];
}
