iPhone Keyboard Covers UITextField

I have an app where, in Interface Builder, I set up a UIView that has a text field near the bottom of the view. When I run the app and try to enter text into that field, the keyboard slides up overtop of the field so I can't see what I'm typing until I hide the keyboard again.

Has anyone else run into this problem and found a good way to solve it without either making the parent view scrollable or moving the text field farther up the screen?

Solution 1:

The usual solution is to slide the field (and everything above it) up with an animation, and then back down when you are done. You may need to put the text field and some of the other items into another view and slide the view as a unit. (I call these things "plates" as in "tectonic plates", but that's just me). But here is the general idea if you don't need to get fancy.

- (void)textFieldDidBeginEditing:(UITextField *)textField
{
    [self animateTextField: textField up: YES];
}


- (void)textFieldDidEndEditing:(UITextField *)textField
{
    [self animateTextField: textField up: NO];
}

- (void) animateTextField: (UITextField*) textField up: (BOOL) up
{
    const int movementDistance = 80; // tweak as needed
    const float movementDuration = 0.3f; // tweak as needed

    int movement = (up ? -movementDistance : movementDistance);

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

Solution 2:

This worked wonders for me sliding uitextfields

In particular it has the benefit of calculating the slide animation distance depending on the position of the text field.
