鍵盤出現時偏移UITableView內容

Question

嗨，我收到錯誤：在'ViewController *'類型的對象上找不到屬性'editingIndexPath'，其中包含以下行：
[self.tableView scrollToRowAtIndexPath:self.editingIndexPath atScrollPosition:UITableViewScrollPositionTop animated:YES];

該錯誤與此調用有關： self.editingIndexPath

我該如何解決這個錯誤？

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    [[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
{
    CGSize keyboardSize = [[[notification userInfo] objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;

    UIEdgeInsets contentInsets;
    if (UIInterfaceOrientationIsPortrait([[UIApplication sharedApplication] statusBarOrientation])) {
        contentInsets = UIEdgeInsetsMake(0.0, 0.0, (keyboardSize.height), 0.0);
    } else {
        contentInsets = UIEdgeInsetsMake(0.0, 0.0, (keyboardSize.width), 0.0);
    }

    self.tableView.contentInset = contentInsets;
    self.tableView.scrollIndicatorInsets = contentInsets;
    [self.tableView scrollToRowAtIndexPath:self.editingIndexPath atScrollPosition:UITableViewScrollPositionTop animated:YES];
}

- (void)keyboardWillHide:(NSNotification *)notification
{
    self.tableView.contentInset = UIEdgeInsetsZero;
    self.tableView.scrollIndicatorInsets = UIEdgeInsetsZero;
}

編譯器告訴你一切。 只需定義editingIndexPath屬性即可。

@property(nonatomic, strong) NSIndexPath *editingIndexPath
