Moving view when UITextField Keyboard gets activated

Question

The following problem occurs when I activate my UITextField (better if I just show a couple images than try toUIViewwhich is nested within myUITableViewController` as the footer.

Yikes can I just delete this question. Jeez

Answer 1

As I understand the question, you are trying to shift the entire view when the UITextField becomes the first responder (i.e. adds the keyboard to the view)? If that is the case, I would add code in the UITextField delegate method:

#define VIEW_TAG 12345
#define kKeyboardOffsetY 80.0f

- (void)textFieldDidBeginEditing:(UITextField *)textField {
    // get a reference to the view you want to move when editing begins
    // which can be done by setting the tag of the container view to VIEW_TAG
    UIView *containerView = (UIView *)[self.view viewWithTag:VIEW_TAG];
    [UIView animateWithDuration:0.3 animations:^{
        containerView.frame = CGRectMake(0.0f, -kKeyboardOffsetY, containerView.frame.size.width, containerView.frame.size.height);
    }];
}

- (void)textFieldDidEndEditing:(UITextField *)textField {
    UIView *containerView = (UIView *)[self.view viewWithTag:VIEW_TAG];
    [UIView animateWithDuration:0.3 animations:^{
        containerView.frame = CGRectMake(0.0f, self.view.frame.origin.y, containerView.frame.size.width, containerView.frame.size.height);
    }];
}

You don't have to use the 'viewWithTag' method, but simply need to get a reference to the container view, which can also be done by iterating through the subviews.

Adjust your tableview's height when keyboard appears.

Here's an example from a project of mine.

First: listen for keyboard events:

-(void) viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];
    //Be informed of keyboard
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardDidShow:) name:UIKeyboardDidShowNotification object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillHide:) name:UIKeyboardDidHideNotification object:nil];    
}



#pragma mark keyboard

- (void)keyboardDidShow:(NSNotification *)notification
{
    NSDictionary *userInfo = [notification userInfo];
    CGSize size = [[userInfo objectForKey: UIKeyboardFrameEndUserInfoKey] CGRectValue].size;
    CGRect frame = CGRectMake(self.tableView.frame.origin.x,
                              self.tableView.frame.origin.y,
                              self.tableView.frame.size.width,
                              self.tableView.frame.size.height - size.height);
    self.tableView.frame = frame;
}

- (void)keyboardWillHide:(NSNotification *)notification
{
    NSDictionary *userInfo = [notification userInfo];
    CGSize size = [[userInfo objectForKey: UIKeyboardFrameEndUserInfoKey] CGRectValue].size;
    self.tableView.frame = CGRectMake(self.tableView.frame.origin.x,
                                      self.tableView.frame.origin.y,
                                      self.tableView.frame.size.width,
                                      self.tableView.frame.size.height + size.height);
}

I did it like this, its animated so it looks good.

The keyboards height is 216px and it takes .25s for it to stop.

Here is the part from my code:

-(void)textFieldDidBeginEditing:(UITextField *)textField {
if (textField.tag == 2) {
    void (^a)(void) = ^(void){
        [UIView animateWithDuration:.25 animations:^{
            RegNrView.frame = CGRectMake(0, -216, 320, 460);
        }
        completion:nil];
    };

    [[NSOperationQueue mainQueue] addOperationWithBlock:a];
}

}

This makes the UIView and keyboard to move at the exact same time.
