iOS Scrolling a UIScrollView/UITableView When Displaying the Keyboard


Example

There are few approaches available there:

  1. You can subscribe for keyboard appearance events notifications and change offset manually:
//Swift 2.0+
override func viewDidLoad() {
    super.viewDidLoad()

    NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(YourVCClassName.keyboardWillShow(_:)), name: UIKeyboardWillShowNotification, object: nil)
    NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(YourVCClassName.keyboardWillHide(_:)), name: UIKeyboardWillHideNotification, object: nil)
}

func keyboardWillShow(notification: NSNotification) {
    if let userInfo = notification.userInfo {
        if let keyboardHeight = userInfo[UIKeyboardFrameEndUserInfoKey]?.CGRectValue.size.height {
            tableView.contentInset = UIEdgeInsetsMake(0, 0, keyboardHeight, 0)
        }
    }
}
    
func keyboardWillHide(notification: NSNotification) {
    tableView.contentInset = UIEdgeInsetsMake(0, 0, 0, 0)
}

//Objective-C
- (void)viewDidLoad {

   [super viewDidLoad];


    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillHide:) name:UIKeyboardWillHideNotification object:nil];

}

- (void)keyboardWillShow:(NSNotification *)notification {

    NSDictionary *userInfo = [notification userInfo];

    if (userInfo) {
    
        CGRect keyboardEndFrame;
        [[userInfo objectForKey:UIKeyboardFrameEndUserInfoKey] getValue:&keyboardEndFrame];
        tableView.contentInset = UIEdgeInsetsMake(0, 0, keyboardEndFrame.size.height, 0);
    
    }

}

- (void)keyboardWillHide:(NSNotification *)notification {

    tableView.contentInset = UIEdgeInsetsMake(0, 0, 0, 0);

}
  1. Or use ready-made solutions like TPKeyboardAvoidingTableView or TPKeyboardAvoidingScrollView https://github.com/michaeltyson/TPKeyboardAvoiding
