Keyboard Blocks The Screen When Typing

Question

I am making an app with multiple UITextField and UITextView The UITextViewis in the bottom of the screen and whenever typing starts, the keyboard blocks the UITextView

How will I able to move up the view of the form when the keyboard appears on the screen? then move it down again when the keyboard disappears?

Yep, you have to scroll the screen up while the keyboard is displayed. — Hot Licks, Apr 11 '13 at 02:20

The best answer is to try and avoid doing that.

However, if you put your stuff in a UIScrollView or a UITableView you can scroll to the input when it becomes first responder.

I like to use this: https://github.com/michaeltyson/TPKeyboardAvoiding It works really well for me and is easy to use.

Make sure you implement the UITextFieldDelegate in your class. These delegate methods should do the trick for a text field named activeField:

- (void)viewDidLoad
{
    [super viewDidLoad];
    [activeField setDelegate:self];    
    [self configureView];
}

- (BOOL)textFieldShouldReturn:(UITextField *)textField {
    [textField resignFirstResponder];
    return TRUE;
}

// Called when the UIKeyboardDidShowNotification is sent.
- (void)keyboardWasShown:(NSNotification*)aNotification
{
    NSDictionary* info = [aNotification userInfo];
    CGSize kbSize = [[info objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;

    UIEdgeInsets contentInsets = UIEdgeInsetsMake(0.0, 0.0, kbSize.height, 0.0);
    scrollView.contentInset = contentInsets;
    scrollView.scrollIndicatorInsets = contentInsets;

    // If active text field is hidden by keyboard, scroll it so it's visible
    // Your application might not need or want this behavior.
    CGRect aRect = self.view.frame;
    aRect.size.height -= kbSize.height;
    if (!CGRectContainsPoint(aRect, activeField.frame.origin) ) {
        CGPoint scrollPoint = CGPointMake(0.0, activeField.frame.origin.y-kbSize.height);
        [scrollView setContentOffset:scrollPoint animated:YES];
    }
}

// Called when the UIKeyboardWillHideNotification is sent
- (void)keyboardWillBeHidden:(NSNotification*)aNotification
{
    UIEdgeInsets contentInsets = UIEdgeInsetsZero;
    scrollView.contentInset = contentInsets;
    scrollView.scrollIndicatorInsets = contentInsets;
}

- (void)registerForKeyboardNotifications
{
    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(keyboardWasShown:)
                                                 name:UIKeyboardDidShowNotification object:nil];

    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(keyboardWillBeHidden:)
                                                 name:UIKeyboardWillHideNotification object:nil];
}
